How to grow potted clivia and the points to note: watering should not be excessive
When it comes to clivia, I believe every flower lover is familiar with it. Although it lacks the beauty of a peony and the emerald green of a dumb cane, its broad, thick green leaves and fiery red flowers set each other off beautifully, making it an ideal potted flower for beautifying the environment. In daily life, many people choose to grow clivia, so how do you grow potted clivia? Below is a carefully compiled guide to clivia growing methods and points to note; if you want to grow it, you must not miss it~
I. How to grow potted clivia: watering is key
Growing clivia at home is the first choice of many flower lovers, but some people report that their clivia died after being grown for a while. What is going on? In fact, this may be due to overwatering, because among the growing methods and points to note for clivia, watering is very crucial. How do you grow potted clivia? Let us continue reading for the specific methods and points to note.
II. Growing methods and points to note for clivia
1. Potting soil
When it comes to how to grow clivia, potting soil is the first thing to consider. Although many friends buy it directly from flower shops, repotting and changing the soil is always necessary, so the potting soil requirements for clivia are also something we need to understand.
As for the flowerpot: clivia is a famous flower, but the flowerpot is not better the more exquisite it is; breathability is what matters most.
As for the soil: it is best to use tile pieces at the bottom of the chosen flowerpot to help drain excess water. For the soil, you can use a mix of leaf mold, garden soil and a small amount of river sand blended evenly. Reference soil mix: leaf mold 50%, coarse sand 15%, charcoal and tile debris 20%, decomposed fertilizer 15%.
Points to note: Flowerpot: old flowerpots used for many years have poor breathability, so they should be soaked and cleaned, then exposed to sunlight before use; Soil: avoid clayey soil and alkaline soil, otherwise it will lead to poor growth and yellowing leaves.
2. Watering: do not allow excess water to accumulate
No matter what kind of flower you grow, watering is essential, and this is exactly what needs the most attention among the growing methods and points to note for clivia. Clivia roots are fleshy, and standing water in the flowerpot can easily cause root rot, so watering must not be excessive. Grasp the principle: do not water until the soil is thoroughly dry, and when you water, water thoroughly.
Points to note: When watering clivia, never pour water on the leaves, to prevent the leaves from rotting. If you find dust on the leaves, gently wipe the leaf surface with a soft cloth; do not wash it with large amounts of water. During the flowering period, use the method of watering the roots, but the flowerpot must never retain water.
3. Fertilizing: apply thin fertilizer frequently
In clivia growing methods, fertilizing is also very important. Clivia likes fertilizer, but too much fertilizer will also cause problems for clivia, so watering and fertilizing are best done at the same time. During the vigorous growth period, it can be done every 15 to 20 days. There are mainly three types of fertilizer: dry fertilizer, liquid fertilizer and solid fertilizer.
Points to note: For clivia fertilization, in spring and autumn apply a fermented solid fertilizer once a month, and apply liquid fertilizer once a week, mainly nitrogen fertilizer; in winter and summer it is best not to apply additional fertilizer, or in winter apply a solid fertilizer once to clivia, with less nitrogen fertilizer and more phosphorus and potassium fertilizer. Just remember one principle: apply thin fertilizer frequently.
4. Light: it must not be too strong
Among the growing methods and points to note for clivia, although light is indispensable, the requirements are not strict. It is understood that clivia prefers semi-shade and fears direct light. If exposed to strong light, transpiration will be greatly increased; if watering is improper at this time, the leaf color will become dull and scorched yellow, or even wilt.
Points to note: Because summer air temperature and soil temperature are relatively high, it is easy for the root system to become disordered, leading to unbalanced nutrient absorption and phenomena such as neck stretching and leaf bolting. Therefore, when light is strong, clivia should be moved to a shaded place, along with a little more watering.
5. Temperature: it must not be too high
How to grow potted clivia: suitable temperature is key. Clivia fears high temperatures in summer. If the temperature exceeds 30°C, or if it is exposed to scorching sun, cooling measures should be taken, placing clivia in a cool, low-temperature, ventilated semi-shaded place.
Points to note: Although clivia fears high temperatures, it is also not cold-tolerant. If the temperature is too low, it will stop growing or even die. Therefore, in winter, when sunlight is soft, it should be placed indoors in a place with sufficient light; a room temperature above 10°C is enough for it to overwinter safely.
III. Points to note when growing clivia
Although there are already quite a few points to note in the clivia growing methods above, if you want to grow clivia well, there are still a few things we need to pay attention to, such as repotting and pruning. The points to note when growing clivia are specifically as follows:
1. Pruning
In summer, be sure to cut off excess flower stalks of clivia. The normal flowering period of clivia is from New Year's Day to Spring Festival. If it bolts in summer, it cannot produce good flowers, and if not cut off in time, it will consume nutrients and affect normal growth and flowering in winter and spring.
2. Repotting
Among the points to note when growing clivia, repotting is also very crucial. In the second year, flower lovers should change to a 15 cm clay pot, and afterward change to a clay pot one size larger every 2 years. Repotting is best done in spring and autumn, and a temperature of about 20°C is most suitable.
Potted growing methods and points to note for clivia
Clivia is native to southern South Africa and is a perennial herbaceous plant. Its flowering period lasts up to 30-50 days, mainly in winter and spring, and it also blooms around New Year's Day to Spring Festival. It fears strong light, is a semi-shade plant, prefers coolness, fears high temperatures, and its suitable growth temperature is 15-25°C. Below 5°C it stops growing. It likes fertile, well-drained soil and moist soil, and fears dry environments. It has very high ornamental value. In China it is often grown in pots in greenhouses for viewing. Now let us take a look at what the growing methods and points to note for clivia are!
Growing methods for clivia
1. Soil: Clivia is suitable for soil rich in humus. This kind of soil has good breathability and water permeability, and the soil is fertile and slightly acidic (pH6.5). Generally, the soil mix for clivia is 6 parts leaf mold, 2 parts pine needles, 1 part river sand or furnace ash residue, and 1 part base fertilizer (hemp seed, etc.). Leaf mold mainly refers to oak leaves, also called oak. This kind of leaf is thick in texture and is very good humus. It is nutritious and has good water permeability. Other leaves are too thin and disappear after decaying, so they cannot be mixed with other media to make soil. When cultivating, use pots that gradually increase in size as the plant grows. For one-year-old seedlings, use a 3-inch pot. In the second year, change to a 5-inch pot, and afterward change to a flowerpot one size larger every 1-2 years. Repotting can be done in spring and autumn.
2. Light: Clivia is a plant that likes moisture and is suitable for growing in high-humidity environments, but it does not have high light requirements. As long as the temperature is suitable, it does not matter whether the light duration is a little longer or shorter. Although good light can ensure bright clivia flower colors, it still prefers slightly weaker light, so strong light must be avoided.
3. Repotting: When clivia grows up, it needs to be moved to a larger pot, which is "repotting and changing soil." The best time to change soil is spring and autumn, because clivia grows vigorously then and will not have its growth affected by changing the soil. The most crucial point when changing soil is to pack the roots firmly with soil. Otherwise, if there is no soil around the roots, water and nutrients will not reach the roots, easily causing root rot.
4. Watering: Clivia has relatively well-developed fleshy roots, and the roots store a certain amount of water, so this flower is relatively drought-tolerant. However, even drought-tolerant flowers cannot be severely short of water, especially in summer when high temperatures are combined with dry air; do not forget to water in time, otherwise the roots and leaves of the flower will be damaged, causing new leaves to fail to sprout and the original leaves to scorch, which not only affects flowering but may even cause the plant to die. However, too much watering will also cause root rot. So you must grasp it well, often observe the dryness and moisture of the potting soil, and water once when it becomes half-dry, but the amount watered should not be too much. Keeping the potting soil moist but not soggy is just right.
5. Fertilizing: Many flowers like fertilizer, but fertilizing fertilizer-loving flowers also has a limit. Too much fertilizer is unfavorable for growth and may even cause root rot or scorching of the plant. Clivia also belongs to this type of plant, and fertilizer must be applied in appropriate amounts. Flowers have different nutrient needs at different growth and development stages. Therefore, different fertilization methods suitable for the plant's needs should be adopted at each stage. Such as base fertilizer, additional fertilizer, and foliar fertilization.
① Base fertilizer (also called basal fertilizer): The purpose is to create conditions for plant growth and development and meet its nutrient needs. Base fertilizer for clivia should be applied when repotting every 2 years. Commonly used fertilizers mixed into the soil include barnyard manure (that is, poultry and livestock manure), compost, green manure, bean cake fertilizer, etc.
② Additional fertilizer: Mainly to promote plant growth. Clivia can be given fertilizers such as cake fertilizer, fish meal, bone meal, etc. Apply less at the initial planting stage, and afterward, as the plant grows larger and the leaves increase, the amount of fertilizer should gradually increase. When fertilizing, scrape open the potting soil and apply it into the soil at a depth of 2-3 cm, but note that the fertilizer applied should not be too close to the root system, to avoid burning the roots. Applying this kind of solid fertilizer once a month is generally enough; it should not be more frequent.
③ Additional liquid fertilizer: Additional liquid fertilizer is made by soaking and fermenting animal and plant materials, then diluting the decomposed supernatant with 30-40 parts clean water and pouring it onto the potting soil. For small seedlings, dilute with 40 times water; for medium seedlings, dilute with 30 times water; for large seedlings, dilute with only 20 times water. After applying the fertilizer solution, water once with clean water 1-2 days later (the amount of water should not be too much), so that the fertilizer penetrates the root system in the potting soil and fully exerts its fertilizing effect. Do not water 1-2 days before applying liquid fertilizer; let the potting soil become somewhat drier before applying the fertilizer solution, which is more effective. The best time to fertilize is early morning; when watering it on, the fertilizer solution should be poured along the edge of the pot, and care should be taken to avoid applying it on the plant and leaves. In addition, the type of fertilizer should also be chosen according to the season. For example, in spring and winter, it is suitable to apply some phosphorus and potassium fertilizers, such as fish meal, bone meal, hemp cake, etc., which help leaf vein formation and improve leaf glossiness; in autumn, it is suitable to apply a leachate of decomposed animal hair, horns, hooves, or bean cake, diluted with 30-40 times clean water and poured on, to promote leaf growth.
④ Foliar fertilization: Fertilizing with this method is mainly to make up for the lack of nutrients in the soil, to solve the problem of nutrient deficiency in the plant, so that seedlings grow faster and flowers and fruits grow plump. Foliar fertilization is spraying the diluted fertilizer solution directly onto the leaf surface of the plant with a misting device, allowing nutrient elements to penetrate the leaf epidermal cells and stomata into the leaf tissues and then be transported throughout the plant. Commonly used fertilizer types include urea, monopotassium phosphate, superphosphate, etc. When spraying, spray evenly on both the front and back sides of the leaves. Spray once every 4-6 days during the growing season, and once every 2 weeks during semi-dormancy. Generally spray after sunrise. After the plant blooms, spraying should be stopped. It must be noted that this method can only be used when the plant is found to be lacking fertilizer. If the plant has sufficient nutrients and is growing vigorously, it should not be used.
Later-stage management of clivia cultivation
The flowering period of clivia is generally from February to April. After flowering, the flowering period can be extended by appropriately lowering the temperature, increasing ventilation and reducing light. The length of the clivia flowering period can be controlled through people's cultivation techniques.
1. Fertilizing: Apply an additional round of bone meal, well-fermented fish innards, and bean cake water, which can make the flower color vivid, the flowers larger, and the leaves thicker. Otherwise, it is easy to have small flowers, few in number, and pale flower color. At the same time, care should be taken to avoid excessive nitrogen fertilizer and insufficient phosphorus and potassium fertilizer, which would lead to weak growth or leggy leaves and affect bud formation and flowering.
2. Light: A certain amount of light should be provided to meet the requirements of photosynthesis and flowering for light. Under strong light, the flowering period is short and the flower color is vivid; under weak light, the flower color is pale. Too long or too strong light, or long-term shading and insufficient light, will all affect the production and accumulation of nutrients, preventing bud formation and flowering.
3. Temperature: Suitable temperature has a clear effect on the quality of flowering. If the temperature is too high, root hairs exist for an extremely short time, and the function of absorbing water and fertilizer is greatly reduced, causing clivia to enter a semi-dormant state; if the temperature is below 10°C, growth will also be inhibited; during the growing period it should be controlled at 15-25°C, and during the flowering period it should be 15-20°C. When root hairs exist for a long time and the water and fertilizer absorption function is good, the leaves grow short and wide, and the flowers are luxuriant. It should also be noted that clivia needs to maintain a temperature difference of about 8°C between day and night, because the organic matter it produces under higher daytime temperatures needs to be stored and digested under lower nighttime temperatures.
4. Water: Clivia cannot lack water throughout the plant's growth period, and its water demand is even greater once it enters the flowering period. The growing humidity should not be lower than 60%.
Causes of clivia flower stalk jamming and treatment methods
1. Causes of flower stalk jamming
① Temperature too low: The temperature for clivia to send up its stalk is about 20°C. If the temperature remains below 15°C for a long time, its flower stalk is very difficult to grow out.
② Insufficient nutrition: Clivia has a relatively large demand for phosphorus and potassium fertilizer during bud formation and flowering. If lacking, the power for clivia to send up its stalk will be insufficient, resulting in flower stalk jamming.
③ Lack of oxygen in the potting soil: During the bud formation period, the clivia root system has a large oxygen demand. If the potting soil is too fine or remains in a relatively moist state for a long time, the permeability of the potting soil will be reduced, resulting in oxygen deficiency and causing flower stalk jamming.
④ Constant-temperature cultivation: Clivia flowering requires a day-night temperature difference of 5°C to 8°C. If the plant is kept at basically the same temperature during both day and night, it will affect nutrient accumulation in clivia, and flower stalk jamming is very likely to occur during the flowering period.
⑤ Root damage or root rot: If the clivia root system is damaged or rotted, the channel for nutrient absorption will be blocked, affecting the plant's stalk emergence and flowering.
⑥ Poor variety: Some clivia varieties are naturally prone to flower stalk jamming.
2. Prevention and control measures
① Adjust temperature and increase temperature difference: In early winter, after clivia has undergone low-temperature treatment for about 20 days, place the plant under normal cultivation temperature at the appropriate time, and try to keep the day-night temperature difference at 5°C to 8°C.
② Apply more phosphorus and potassium fertilizer to ensure nutrition: In autumn and winter, appropriately apply more phosphorus and potassium fertilizer to promote flower formation and stalk emergence.
③ Ensure an appropriate water supply: During the period when clivia sends up its stalk, ensure that the water content of the potting soil is between 30% and 50%.
④ Use both medicine and manual assistance to promote stalk and urge flowering: You can apply clivia stalk-promoting agent bought on the market to the flower stalk according to the instructions, or drip it into the potting soil; you can also manually spread apart the leaves on both sides of the jammed stalk, but do not damage the leaves, in order to reduce the clamping force of the leaves on the flower stalk and prompt the flower stalk to extend and grow taller as soon as possible.
⑤ Change the soil again, first dry then wet: When changing the soil again, note that you should not water within 5 days after changing the soil. The replacement soil cannot be dry soil; it should maintain about 30% moisture. After 5 days, water heavily once. In this way, it can generally send up a stalk and bloom.
Points to note when growing clivia
1. Clivia likes a semi-shaded, cool environment, and absolutely avoid high temperature, strong light and dryness. The most suitable temperature is 15-25°C. Below 5°C it begins to go dormant and stop growing. High temperatures are also unsuitable, and in summer attention should be paid to avoiding heat. Otherwise, the leaves will become long and narrow and affect the ornamental value, so it should be cooled in time.
2. During the clivia growing period, keep the potting soil moist. During the high-temperature semi-dormant period, the potting soil should be on the drier side, and water should often be sprayed on the leaf surface to achieve the purpose of cooling. Clivia likes fertilizer. Repot once every 2 to 3 years in spring and autumn, adding leaf mold to the potting soil. Turn the pot often to prevent the leaves from leaning to one side.
How to grow potted clivia, potted clivia methods
Clivia is also called arrow-leaf stone garlic and large-leaf stone garlic, in the Amaryllidaceae family, Clivia genus. It is a perennial herb that prefers a warm, moist, semi-shaded environment. It fears heat, is not cold-tolerant, and fears direct sunlight in summer. The suitable growth temperature is 16-25°C. Below 5°C it stops growing and enters dormancy. Above 30°C the plant is also in a semi-dormant state. Home potting is a good way to grow clivia, so do you know how to grow potted clivia and what the potted clivia methods are?
How to grow potted clivia
1. Temperature: The suitable temperature for clivia growth is 15-25°C. When the summer temperature exceeds 30°C for a long time, growth is inhibited. At this time, if the air humidity is below 60%, clivia leaves will become lighter and yellow and even wilt; if the humidity is above 90%, the stems and leaves will grow leggy. To prevent these undesirable phenomena, appropriately lower the temperature, pay attention to ventilation and light transmission, and control humidity. When the temperature drops below 5C, clivia basically stops growing. If the temperature drops to about 0C, frost damage may occur, causing the leaf tips and leaf edges to lose green and turn yellow, and even yellow-white necrotic spots to appear. Therefore, in winter, good warmth protection should be done for clivia to prevent frost damage.
2. Light: Clivia is a semi-sun plant and prefers scattered light. Too strong light is unfavorable for its growth and easily causes sunscald. However, if the placement location is too dark and light is insufficient for a long time, the leaves will also lose their luster, old leaves will be dark green, and new leaves will become thin and yellow or yellow-green. Some people call this yellow-leaf phenomenon shade yellowing. At this time, clivia should be moved to a place with slightly stronger light. If it is not suitable to move it, use lamplight to supplement illumination.
3. Soil and fertilizer: Clivia likes loose, fertile sandy loam. Soil compaction and insufficient fertilizer supply will make the leaves yellow and affect flowering. At this time, apply more dilute liquid fertilizer and pay attention to loosening the soil.
4. Water: Clivia likes moisture. If the potting soil is too dry for a long time and the temperature is also high, the leaves are prone to yellowing. But long-term excessive watering can also easily lead to disease. Therefore, in clivia cultivation, in spring and autumn the soil should be kept moist, in the winter dormant period it should be slightly drier, and in summer the potting soil should not be too warm. You can appropriately spray clean water on the leaf surface and surrounding ground every morning or evening to maintain a cool environment.
5. Ventilation: If clivia is placed too densely and the surrounding environment is closed off, it will hinder air circulation and make the plant weak, yellow and thin. Therefore, indoor ventilation should be strengthened and crowded placement should be avoided.
The above is the article on how to grow potted clivia and potted clivia methods. Clivia is suitable for growing in loose, fertile soil rich in humus and slightly acidic, and absolutely avoid standing water. In winter, place it indoors, and it can overwinter safely at a room temperature above 5°C. Common clivia varieties include large-flowered clivia and drooping clivia. The flowering period is from April to June, and propagation methods mainly use division and sowing.
