Growing Techniques Jan 1, 1970 0 views

When it comes to the orchid, this is a plant that many people absolutely adore. Just hearing the name conjures up elegance, but keeping an orchid thriving is no easy task. Let's take a look at why orchid leaves turn yellow, wither, and roots rot. What to do when orchid leaves develop spots: Why leaves turn yellow

I. Why Leaves Turn Yellow

1. Yellowing leaf surface

If the leaf surface or leaf edges turn yellow but there are no other symptoms and growth is relatively normal, this is usually caused by sunlight that is too intense. If the leaf color is dull, then there is too little light. Move it to a spot with suitable light, with 3-5 hours of scattered light per day.

2. New leaves yellow or weak

If newly grown leaves turn yellow or become smaller, then the soil is lacking nitrogen or the environmental humidity is insufficient. At this point, you need to mist more often and appropriately increase nitrogen fertilizer supplementation.

3. Bottom leaves drop off and turn yellow

This is usually caused by careless watering. If you repotted not long ago, it is also easy for leaves to drop and bottom leaves to turn yellow. At this point, you need to control watering frequency, and the soil must absolutely not become waterlogged.

II. Why Do Leaves Wither?

Orchid leaf blight is also one of the most common diseases. You can see small reddish-brown or grayish-brown disease spots at the leaf tips, which slowly spread to the entire leaf. It is best to prevent and treat it early, as it can be easily resolved.

The first thing to do is naturally to remove the diseased leaves. Cutting off the source of infection is the most critical step. Combine this with spraying a fungicide, such as Bordeaux mixture, once a week (three sprays) and it will be fine.

Of course, you should also improve the care environment. After an orchid becomes diseased, isolate it from other plants. Repot the following year, and the pot and soil must both be disinfected before use.

III. Why Do Leaves Develop Disease Spots?

1. Fungal infection

This condition is also easily contracted during cold winter weather, and in severe cases it can affect blooming. At this point, isolate the diseased plant, disinfect and sterilize promptly, first clean up the diseased leaves thoroughly, and leave no diseased leaves in the pot soil. You can spray with chlorothalonil, and it can be used alternately with dimethoate emulsifiable concentrate.

2. Anthracnose

This is one of the most common orchid diseases. Roundish gray or black spots can be seen on the leaf surface, slowly enlarging. Promptly cut off the diseased leaves, spray Bordeaux mixture 2 times (once per week), and also improve ventilation and water appropriately.

IV. How to Handle Orchid Root Rot

At this point, you can see the orchid's leaves turning black, especially near the root crown.

What you need to do is dig out the diseased plant, rinse it clean with water, and use a sharp knife to cut away the rotted parts.

Then soak it in a 0.1% potassium permanganate solution for 30 minutes. You can apply plant ash to the wounds to speed up healing and also prevent bacterial infection.

What to Do When Clivia Leaves Turn Yellow? Pest and Disease Prevention Methods for Clivia

What should you do when Clivia leaves turn yellow? Today let's look at the causes of yellowing Clivia leaves and how to handle them.

Clivia (scientific name: Clivia), also known as sword-leaf bush lily, is an ornamental flowering plant in the genus Clivia, family Amaryllidaceae. It is native to southern South Africa. In China, it is often grown in greenhouses as a potted ornamental. It propagates by division or seeds. The nodding Clivia (C. nobilis) has the same uses and is cultivated in greenhouses in various regions.
Perennial herb, with fleshy roots. Basal leaves are leathery, numerous, broadly strap-shaped, with leaf bases arranged in two rows tightly clasping each other to form a bulb-like structure. It blooms in spring and summer. The scape is upright, flat, and fleshy, bearing a terminal umbel with many flowers, yellowish-red on the outside and yellow on the lower inner side. The berry is purplish-red.

Yellowing Clivia leaves often occur in summer and greatly reduce its ornamental value. If your Clivia is showing these symptoms, then take a quick look at the following causes and solutions.

The entire leaf turns yellow.

This is caused by sunlight that is too intense, scorching the Clivia. The solution is to cut off the yellowed leaves and provide shade. After some time, the yellowing of Clivia leaves will decrease.

Yellowing starts from the leaf tip.

This may be caused by the soil being too raw or too rich in fertilizer, and should be handled according to the actual situation.

Individual leaves turn yellow.

The most likely cause of this is insufficient light for the Clivia. The corresponding measure is to supplement with artificial light or place it in a position with ample sunlight.

Yellow leaves in Clivia (including deterioration of leaf tips) are mostly caused by improper watering, fertilizing, and soil use, which first causes root rot and then leads to yellow leaves. Therefore, you should take the plant out of its pot to inspect it, cut off the rotted roots, replace the soil, and repot, while also cutting off the yellow leaves to reduce the burden on the plant. The main causes of root rot are:

1. Under poor ventilation, a large amount of water will cause root rot, because the water poured into the pot cannot evaporate for a long time, the plant's metabolic function will be hindered, which will inevitably lead to root rot.

2. Applying excessive fertilizer or unfermented fertilizer: when the room temperature rises above 25°C, it will ferment in the pot and generate high heat, thus burning the roots. 3. Using alkaline soil, clay soil, or undecomposed horse manure soil to grow Clivia: some are not loose, some have poor air permeability, and some will cause high temperatures in the pot soil, which can also cause root rot.

10 Solutions for Yellowing Clivia Leaves

1. Clivia leaves turn yellow, and the small central leaves turn black and rot

Solution: When this symptom appears, you first need to use the above 9 methods to address the root cause. If the small central leaves turn black and rot, further judgment is needed. Pry apart two leaves to check. If the gap between the leaves is black and oozing decayed liquid, then it can be determined that a formed Clivia flower scape failed to grow out from between the leaves in time and instead rotted directly in the middle of the leaves.
There are many causes of flower scape rot: one is that the flower was sprayed with too much water while in the owner's care, causing dirty water to flow into the gaps and leading to bacterial infection and rot; another situation is that careless watering caused dirty water to splash into the gaps and cause rot. Consequences: Generally it will not affect the life of the plant, but in high-temperature and high-humidity weather, it can easily cause the plant head to drop off and the entire plant to rot. Handling method: You can use toilet paper or facial tissue to absorb the decayed liquid, use an appropriate method to remove the debris that can be cleaned, keep the environment relatively dry in normal times, and it is recommended to use the bottom-watering method.

2. All Clivia leaves turn yellow

Solution: When all leaves turn yellow, it is often a symptom of sunscald. Solution: Immediately provide shade and cut off the yellow leaves.

3. Clivia leaves wither, yellow, and droop

Solution: Withered, yellow, or drooping leaves are symptoms of water shortage. Watering should follow the principle of not watering until dry, and no water accumulation in the pot.

4. Localized yellowing of Clivia leaves

Solution: Localized yellowing is very likely caused by heat scorching, cold wind, hot water, or acid-base damage. Simply eliminate the external cause promptly. Sometimes, insufficient nitrogen fertilizer may cause the plant to suffer from chlorosis. The reduction of chlorophyll leads to yellowing of the leaves. In this case, increase the application of fermented cake fertilizer water. (Growing methods also differ by season.)

5. Clivia leaves wrinkle and develop yellow spots
Solution: Excessive fertilization causes root burn. Immediately change the soil, and use a 0.1% potassium permanganate aqueous solution to soak the roots for 20-30 minutes, then rinse with clean water, air-dry, cut off the rotted roots, apply plant ash to the wounds, and replant.

6. The two outer leaves of Clivia turn yellow (grown for 4 years)

Solution: This is normal metabolism of new growth layers. Simply prune off the 2 outer leaves.

7. Clivia leaves appear grayish-yellow

Solution: The main cause of grayish-yellow Clivia leaves is direct sunlight that is too strong. Clivia needs to be shaded.

8. Clivia leaves show chlorosis symptoms

Solution: Due to insufficient light, if the room is very dark, Clivia will become chlorotic. Solution: Use fluorescent lamps to supplement light.

9. Clivia leaves are yellow and weak

Solution: Yellow and weak leaves indicate a fertilizer deficiency. Apply thin fertilizer frequently. Yellowing leaves indicate the soil is raw and not breathable. You should change to leaf mold soil or pine needle soil.

10. Yellowing of lower leaves causes root rot

Solution:

Materials: scissors, utility knife, chlorothalonil, rooting water, nutrient solution, spray bottle.

Steps:

①: Pull the Clivia out by the roots.

②: Use a utility knife to cut off old leaves and rotted leaves.

③: Use scissors to cut off already rotted roots and old roots.

④: Mix water and chlorothalonil in a 3:5 ratio in the spray bottle.

⑤: Put the Clivia back into the pot.

⑥: Water with rooting water and nutrient solution.

⑦: At first, water about 2 times a month for 5 months.

⑧: After 5 months, water about 4 times a month for 2 months.

⑨: Return to normal watering frequency.

⑩: Done.

Methods to Prevent Clivia Leaves from Turning Yellow:

The main cause of yellow Clivia leaves is improper management. The reasons for yellowing Clivia leaves are generally the following:

1. Overwatering (water-induced leaf yellowing): If the flower pot retains water for too long, the leaves are prone to water-soaked yellowing, occurring at the tips of young leaves, with symptoms developing from top to bottom. This is the common "water yellow," caused by watering too frequently. Its characteristic is that old leaves show no obvious change while young leaves turn yellow. In this case, immediately control watering.

2. Lack of water (drought-induced leaf yellowing): If it is too dry, or if only half-watering is done each time, the old leaves will develop yellow tips. Caused by water shortage and drought, its characteristic is that old leaves turn yellow first from bottom to top. If the water shortage lasts a little longer, the whole plant's leaves will turn yellow, or even die. Water promptly.

3. Excess fertilizer (yellowing caused by over-fertilizing): Applying too much or too concentrated fertilizer will cause root burn and yellow leaf tips. Caused by fertilizing too frequently or at too high a concentration; its characteristic is that young leaves are thick, glossy, and uneven. You should reduce fertilizer, cultivate the soil, and water.

4. Nutrient deficiency chlorosis (iron deficiency): If the pot soil lacks iron, the leaf tips will turn yellow first. If it lacks nitrogen, new leaves appear yellowish-white.

5. Yellowing caused by insufficient nutrients: Caused by insufficient fertilizer, low fertilizer concentration, and too-long intervals between fertilizing; its characteristic is that young leaves and tender stems turn yellow first. If this phenomenon is not followed by timely fertilization, it can also cause the whole plant's leaves to turn yellow or even die. For flowers lacking fertilizer, never apply a large amount of concentrated fertilizer at once, to avoid root burn. For woody flowering plants in greenhouses, due to large changes in soil fertility conditions, yellowing often occurs; its characteristic is that young leaves are obviously affected, old leaves are less so, the leaf flesh is yellow, the veins are green, and a typical network pattern forms. This can be solved by applying ferrous sulfate aqueous solution. The method is: mix 7 parts cake fertilizer, 5 parts ferrous sulfate, and 200 parts water into a diluted solution and water with it.

6. Sunscald: After strong direct sunlight (in summer), yellow spots appear on the leaves, called sunscald. In high temperature (above 30°C) and dry conditions, leaves also easily become withered and yellow.

7. Pollution: Clivia leaves should be kept clean. If dirty things splash on them, the contaminated areas may turn yellow.

8. Freeze damage: Clivia suffers freeze damage below 0°C, and the symptom is still yellow leaves. To restore normal growth to Clivia with yellow leaves, you need to find the source of the problem and take corresponding measures. The method is: dig out the entire Clivia to check the roots. If there is root rot, remove the rotted parts, replace with new soil, and replant, placing a layer of fine sand under the roots. The pot soil should be loose leaf mold soil, with a pH preferably neutral. Keep the soil neither dry nor wet, with good air permeability. Clivia prefers weak light. Except in winter, place it in a semi-shaded, semi-sunny spot in summer, avoiding direct sunlight. If "chlorosis" occurs, you can add liquid fertilizer (such as black alum fertilizer water). The key point is small amounts and frequent applications. Be careful not to splash fertilizer liquid or mud onto the leaves or stems. If it splashes on the leaves, rinse it off promptly with clean water. When applying solid fertilizer, also avoid direct contact with the fleshy roots.

Questions About Handling Yellowing Clivia Leaves

1. Can yellowing Clivia leaves be pruned?

The key is to figure out why there are yellow leaves.

Common causes of yellow leaves include:

①Keep it in a semi-shaded spot for care. If the sun is too strong, the leaves will get sunburned and turn yellow.

②Clivia has fleshy roots. Keep the pot soil slightly moist. Overwatering will damage the roots and the leaves will turn yellow.

③Yellowing leaves due to fertilizer deficiency: apply a thin nitrogen fertilizer once every half month to Clivia. Do not fertilize in the hot summer to avoid root damage. Yellowing Clivia leaves can be pruned. Hold the scissors over a flame to sterilize them, then cut off the yellow leaves. But do not tear them off.

2. Solutions for yellowing Clivia leaves in spring:

After a winter, the Clivia's leaves have turned yellow and withered. Will it still survive in spring?

It should be able to. Repot it, remove the dead leaves and hollow roots, use special Clivia soil mixed with large pieces of orchid stone, soil:orchid stone = 3:2. After repotting, water thoroughly once, place in a spot with scattered light and ventilation to let it recover for 1 month, then gradually expose it to light over a week, and return to normal care. Do not expose it to strong sun.

3. Solutions for yellowing Clivia leaves in summer:

Check whether it is usually being overwatered. Too much water easily causes root rot, leaf rot, and core rot, and water should be poured into the pot soil, not on the leaves, especially not into the central leaves. If the pot soil is often too wet, it will cause water to flow backward, and then, as you described, blackening and rotting will gradually appear starting from the leaf tips. Therefore, Clivia pot soil should preferably be on the drier side. In addition, summer temperatures are relatively high. If its growing environment temperature drops below 25°C, you can also apply a thin liquid fertilizer diluted at 1:20 or more in summer, once every half month. This can promote Clivia's growth and shorten or eliminate its dormancy period. There is another situation: light that is too strong. Clivia prefers soft light. If exposed to strong direct light, the leaf surface will become rough, the leaf color will turn yellow and dark, losing its emerald green, and it is also prone to "sunscald."=========================================================================

Summary: Growing Clivia is something that requires constant summarization and constant discovery of problems. Only with careful observation and meticulous care can you grow Clivia with ornamental value. Finally, I wish all friends' Clivia healthy growth.

Common Clivia Diseases

Diagnosis and Treatment of Diseases
Because unsuitable cultivation conditions often allow pathogens to invade, Clivia develops diseases. Mild cases affect its ornamental value, while severe cases lead to plant death. Therefore, early diagnosis of the type of Clivia disease and timely prevention and treatment measures are very necessary.
1. Leaf blight: Occurs at the tips of young leaves, with symptoms developing from top to bottom. In severe cases, the entire leaf turns yellow and withers. This disease is caused by root crown rot, also called root rot, which is a relatively serious disease caused by a fungus invading the roots. It mainly damages the root crown area of the plant and the cortex and phloem of nearby stems above the ground. It is a physiological disease caused by excessive fertilization or overwatering. If it is due to excess fertilizer, change the pot soil, place a layer of fine sand under the roots, and use loose leaf mold soil with a neutral pH. If it is due to too much water, control the amount of watering and remove the yellow leaves; the plant can still return to normal growth.
2. Leaf spot disease: Small yellow spots appear on the leaves, and the lesions enlarge to about 3-5 mm in diameter, round in shape. When the lesions spread and merge into one area, the leaves will wither and yellow. Another type is larger lesions on the leaves, irregular in shape, yellow-brown to gray-brown, with slight concentric rings, and later small black dots appear on the back of the lesions. Both of these diseases are caused by poor ventilation and parasitic scale insects, which lead to weakened plant growth. The control method is: apply 0.5% potassium permanganate solution to the lesions, or spray with 50% carbendazim 1000x solution. If the disease is severe, remove the affected leaves, burn them, and absorb the wound with sterile absorbent cotton.
3. Bacterial soft rot: Pathogens invade through mechanical wounds or damage caused by scale insects, harming the leaf sheath and leaf core. The rotted area should be cut away, the wound blotted dry with absorbent cotton, and then smeared with 0.02% streptomycin.

Handling Root Rot

When Clivia is divided, if the wounds are not disinfected and become infected by bacteria; or during cultivation, overwatering, poor soil permeability, overly concentrated fertilizer, or application of unfermented raw fertilizer are all common causes of Clivia root rot. In large mature Clivia, if individual roots rot, it will show as some leaves with dry tips, blackened blades, and scorched, falling leaves. Find the cause, overcome it, and stop the root rot from continuing.
When many roots have rotted, most of the leaves will fall off, leaving only the small central tongue leaves. In severe cases, the plant becomes unstable, and a light touch with the hand makes it sway. At this point, take it out of the pot, and you can see that some of its fleshy roots have rotted entirely, while others are half-rotted. The rotted roots are left with only a shriveled, membranous outer skin, and over time the outer skin also becomes soft and rotted. When this is discovered, shake off all the soil, rinse the roots clean with water, carefully remove the rotted roots, and use clean scissors to cut off the rotted parts. Then soak the roots in a 0.1% potassium permanganate solution for disinfection. After 5 minutes, lift out the roots, rinse with clean water to remove the disinfectant, dip in a small amount of sulfur powder or plant ash, air-dry the surface indoors, and replant in a pot. When repotting, plant shallowly, just covering the stem disc, and the pseudobulb should be exposed above the soil surface, which is beneficial for rooting. After watering thoroughly once, place in a semi-shaded spot for care. Afterward, mist frequently or cover with a plastic film to keep air humidity as high as possible and water less. Maintain the temperature at around 20°C until the small tongue leaves grow. By then new roots have emerged, and you can switch to normal water and fertilizer management. Young plants have few and very delicate roots. If root rot occurs, the roots will quickly rot completely and the leaves will droop. When these situations occur, promptly take the plant out of the pot, clean off the residue on the not-yet-rotted stem disc, rinse, disinfect, air-dry the surface, and then insert it shallowly into plain sand following the cutting method. Under environmental conditions of 20-25°C, provide shade, maintain relatively high air humidity and moist cutting soil, let it produce new roots, and once the leaves recover their vitality, promptly repot with leaf mold soil.
Common Viruses
Several common diseases of Clivia include southern blight, soft rot, and anthracnose.
Southern Blight
When this disease occurs, water-soaked, irregular brown lesions appear on the stem near the roots, the cortex becomes soft and rotted, and then white silky mycelium grows and spreads over the soil surface around the roots. Later it forms small sclerotia, which finally become colored like rapeseed, enlarging until the entire base rots and dies.
Prevention and control methods:
1. Before potting, the growing soil should be disinfected. A relatively simple method is to place the growing soil at 60°C for 24 hours.
2. Frequently observe the soil surface. If white mycelial threads are found, pick them out and burn them, and sprinkle some lime powder around the diseased area for disinfection.
3. In the early stage of the disease, irrigate the stem base and surrounding soil with 50% carbendazim wettable powder 500x solution, once a week, 2-3 times is sufficient.
Soft Rot
Pathogens often invade through wounds. When the disease occurs, pale yellow water-soaked spots appear on the leaves, then expand into irregular lesions, causing the leaves to become brown and soft-rotted, with bacterial liquid flowing from the wound lesions.
Prevention and control methods:
1. Once this disease is discovered, immediately separate the diseased plant, dig away the growing soil around the plant to expose the affected area, pry open the rotted leaves, use a sterilized knife to scrape away the rotted parts, expose to appropriate sunlight, and keep ventilated and dry.
2. If many plants are rotted, all diseased tissue must be removed, soaked in 5% potassium permanganate aqueous solution for 1 hour, rinsed with clean water and air-dried, apply plant ash to the cuts, repot in new pots, and place in a well-ventilated spot with low temperature.
3. For drug treatment, penicillin, streptomycin, or oxytetracycline diluted with 4000-**** times water solution can be sprayed or applied to the lesions, with some efficacy.
Anthracnose
This disease mostly occurs in rainy, humid, and stuffy seasons, and the affected areas are mostly at leaf tips and leaf edges. In the early stage, moist brown small spots appear on the leaves, then expand into oval and wave-like main lesions, with yellow surrounding areas, and later gradually shrink and dry up. Pot soil that is too wet and excessive nitrogen fertilizer make this disease more likely.
Prevention and control methods:
1. Provide the flowerpot with a well-ventilated and well-lit environment. The potting soil should only be kept moist; do not water too much or too frequently. Increase phosphorus and potassium fertilizer, and control nitrogen fertilizer.
2. When signs of disease are detected, immediately spray with a solution made from 50% wettable carbendazim powder diluted with 800 times water, or a solution of 60% thiophanate-methyl plus 1000 times water. Spray about once every 6 days; 3-5 sprays will be effective. [5]
Common pests
The common pest of clivia is scale insects. When an infestation occurs, scale insects often gather on the tender tips of the leaves, suck the leaf sap, and secrete large amounts of pathogens, turning the stems and leaves moldy black, causing sooty mold and making the leaves wither. This insect has strong reproductive capacity and can produce multiple generations in a year. A single female adult can often produce hundreds of offspring. If control measures are not taken in time, it can cause death.
Control method: Prevention should be the priority. Usually, frequently observe the plant body, and when pests are found, remove and treat them early to prevent spread. To control scale insects, both manual and chemical methods can be used together. If pests are found on only 1 or 2 leaf tips, manual scraping can be done, using a sharpened thin wooden stick or a bamboo pick to remove the insect bodies. If large numbers of nymphs appear, spray with 25% phosmet emulsifiable concentrate at 1000 times dilution, or spray with a solution made from 40% omethoate emulsifiable concentrate plus 1000-1500 times water. Generally, spraying 1-2 times can kill them.
In addition, note that: earthworms can also become pests of clivia. When the clivia plant is young, its fleshy roots are very tender and weak. If there are earthworms in the potting soil, they often burrow around randomly, injuring the tender roots, destroying the clivia's ability to absorb nutrients, causing the plant to stop growing and developing or causing root rot.
The control method is: frequently check whether there are round soil granules on the surface of the potting soil (that is, earthworm excrement). If found, immediately drench with a solution made from 50% dichlorvos emulsifiable concentrate plus 1500-2000 times water. If earthworms are seen moving after drenching, remove them immediately; repeat the same treatment one week later, and the earthworms can be completely eliminated.

Cultivation history of clivia

In 1823, the Englishman James Bowie discovered Clivia nobilis in the Eastern Cape of South Africa and cultivated it in a private garden at Clive in Northumberland, northern England. In the 1820s, clivia began to be cultivated in European countries such as Germany, Denmark, and Belgium, and was introduced to Japan in 1854.
Clivia is the city flower of Changchun, Jilin Province, China. In 1932, clivia was introduced from Japan to Changchun, China, and at first was cultivated only in the Manchukuo court and imperial garden. After Japan's defeat in 1945, clivia spread from the court to the people for cultivation.

In recent years, China has cultivated more than 160 valuable clivia varieties, and it is a common flower variety in ordinary households. The flowering period is March to April. It likes warm, humid, and semi-shaded environments, is not cold-tolerant, and requires soil with good drainage. There are two propagation methods: division and sowing. Division is carried out in March-April. During the growing period, apply more topdressing; in summer, when it is hot and rainy, generally do not fertilize. Clivia has a long flowering period and evergreen leaves, and is most suitable for indoor potted ornamental display.

How to grow Aspidistra elatior and what to note? What to do if Aspidistra elatior leaves turn yellow

Aspidistra elatior, recorded in the Liliaceae, is an evergreen plant and a perennial herbaceous plant. The more common varieties include spotted-leaf and golden-line types. Its leaves are often used for wrapping zongzi during the Dragon Boat Festival. It has certain medicinal value, ornamental value, and landscaping value, and can absorb exhaust gas, impurities, nicotine, and so on, making it suitable for indoor planting. This article introduces the cultivation methods for Aspidistra elatior and the notes on growing it.

Morphological characteristics of Aspidistra elatior:

For Aspidistra elatior, the main ornamental value is the leaves, while the rhizome part is mainly cylindrical, with a diameter that can reach more than 5 cm, mostly growing in a jointed form. The rhizome is scale-like, with a spacing of 1 cm.

The leaves are solitary, flat, and mostly wedge-shaped at the base. The length of Aspidistra elatior is more than 22 cm, and the width is 8 cm. The leaf margins are wrinkled, both sides are green with yellow-white spots, and the petiole and leaf veins are clear and thick, with a length of about 25 cm.

In Aspidistra elatior, the total peduncle length is about 2 cm, and the color is pale green, or with small purple dots; the perianth is bell-shaped, with a length of more than 12 cm, dark purple on the outside, and split open. The flower shape of Aspidistra elatior is unique, with petals separated from the corolla; the petals are slender and spread out, while the flower tube is bell-shaped, with an inflorescence at the margin, and the inner stamens have small yellow dots, mostly terminal, giving it a certain ornamental value.

Growing conditions of Aspidistra elatior:

Before planting Aspidistra elatior, it is necessary to understand and choose a suitable planting site, mostly flat land, with suitable temperature afterward, no severe heat, no severe cold, and a semi-shaded environment. The most suitable temperature for the growth of Aspidistra elatior is 7-30°C. For example, it can be widely planted in southern China, and is mostly distributed in Sichuan, Yunnan, and so on. During the propagation of Aspidistra elatior, care should be taken for warmth and cooling. A soil moisture content of about 30 percent can be chosen; it is not suitable for planting in tropical regions.

Key points for growing Aspidistra elatior:

Aspidistra elatior can be propagated by division. To ensure a smooth transplanting process for Aspidistra elatior, spring with suitable temperature should be chosen as the propagation period. At the same time, before the new buds sprout during propagation, division and repotting should be carried out. Before sprouting, divide it together with the rhizome into several clumps, which can increase the propagation quantity.

When planting Aspidistra elatior, it has extremely high adaptability to soil, but this does not mean it can adapt to any soil. Loose, fertile soil is the best choice. In daily care, Aspidistra elatior is not suitable for being kept indoors for a long time; combining with light can improve its vitality. Also, when planting Aspidistra elatior, it can be suitable for released cultivation and care; it is only necessary to avoid exposure to blazing sun, which can keep the leaves clear and bright.

Propagation methods of Aspidistra elatior:

Aspidistra elatior mostly uses division as its propagation method, mostly choosing the period in spring when the temperature rises. At this time, before the new buds sprout, lift out the entire plant and sort out the root system;

Afterward, separate the mixed rhizome from the mother plant, or directly use a small knife to separate the side roots attached to the mother plant, ensuring that each root has a complete rhizome;

Trim the leaves and so on of the divided daughter plants; it is only necessary to ensure that each plant has more than 3 leaves and fewer than 5 leaves;

Then soak the daughter plants in a 1500 times solution of chlorothalonil for 5 minutes, then take them out and pot them;

Because after division the rhizome will suffer some damage, the water absorption demand will increase, so the amount and frequency of watering can be appropriately increased, but at the same time the soil moisture should be controlled to avoid water accumulation and root rot;

After division, Aspidistra elatior does not need fertilizing. In addition to daily watering, the leaves can be misted every day, and it can be placed in a shade shed for care;

After division, after about 4 weeks, it will recover to a sprouting state. At this time, transplanting can be carried out. First prepare potting soil, and you can choose perlite, peat, sawdust, river sand, vegetable garden soil, paddy soil, leaf mold, and so on, mixed and blended;

After transplanting, repot once every year can be ensured. Place it mostly in a cool place, ensure sufficient water during the growing period, maintain humidity, and afterward apply a thin liquid fertilizer once a month, which can promote the growth of new buds.

Notes on propagating Aspidistra elatior:

Care details

Aspidistra elatior is not suitable for frequent fertilizing, so the correct fertilizer can be chosen according to the growth of the leaves. If the fertilizer solution is too weak or too strong, it will affect growth. Too much watering will cause water accumulation in the pot, and root rot will be difficult to repair, while excessive fertilizing can easily lead to dead leaves, yellow leaves, death, and so on.

During the new bud sprouting period, Aspidistra elatior can be moved to a balcony, but the time needs to be controlled, maintaining two hours per day. Avoid direct sunlight in summer. If Aspidistra elatior is often placed in a dark environment during the sprouting period, it can easily cause small leaves to be lusterless, wrinkled, and slender and weak.

Aspidistra elatior should avoid being placed directly in a high-temperature environment, so cooling treatment should be carried out in summer. Even short-term exposure to blazing sun may cause the leaves to be scorched. In spring, during the vigorous growth period, the frequency of fertilizing can be reduced, but the soil should be avoided from being directly soaked in water. Watering methods such as root watering and leaf spraying should be used more often.

Pest and disease control

Anthracnose: This is a common pest and disease of Aspidistra elatior. When diseased, lesions mostly appear on the leaves, round, in colors such as gray, white, and grayish brown. In severe cases, the lesions become black, and the rhizome can also be infected. The main cause is excessive water accumulation inside. When the disease is found, the diseased leaves should be trimmed in time to reduce the source of infection. A 300 times solution of double-effect micro-fertilizer can also be sprayed to treat the pest and disease and improve disease resistance.

Gray mold: This pest and disease mostly occurs at the leaf margins, mostly as water-soaked lesions, and spreads quickly. It also affects the growth of Aspidistra elatior, causing irregular leaf shapes and directly leading to withering, and so on. As the climate becomes cool and rainfall is excessive, gray mold will be triggered, continuously producing spores. It has infectious characteristics and is difficult to eliminate.
