Growing Techniques Jan 1, 1970 0 views

Geraniums are perennial herbaceous plants of the genus Pelargonium in the family Geraniaceae, native to southern Africa and widely cultivated around the world. They are highly adaptable, with bright flower colors and a long blooming period, suitable for indoor display, flower bed arrangement and more. In the West, they are excellent flowers for decorating windowsills, and on the European continent, such as in Germany and Austria, they are especially common

Propagation Methods for Geraniums

1. Seed propagation: Can be done in spring or autumn, with indoor pot sowing in spring being preferable. The suitable germination temperature is 20-25°C. Geranium seeds are not large, so after sowing the soil covering should not be deep, and they germinate in about 2-5 days. If sown in autumn, they can bloom the following summer. Seedlings grown from seed propagation can be selected to breed excellent intermediate-type varieties.

2. Cutting propagation: Cuttings can be taken at any time except when the plants are in a semi-dormant state in June-July, but spring and autumn are preferable. In summer, high temperatures cause cuttings to easily turn black and rot. Select cuttings 10 cm long, with the top portion being best, as it has vigorous growth and roots quickly. After cutting, let the cut end dry for several days until a thin film forms, then insert into a sand bed or a mixed substrate of expanded perlite and peat. Be careful not to damage the stem bark of the cutting, otherwise the wound will easily rot. After inserting, place in a semi-shaded area and maintain a room temperature of 13-18°C. Roots form 14-21 days after insertion, and when roots are 3-4 cm long they can be potted.

3. Tissue culture: Geraniums can also be propagated by tissue culture. Using MS medium as the basic medium, add 0.001% indoleacetic acid and kinetin to promote callus and adventitious bud formation from explants, and use 0.01% indoleacetic acid to promote rooting. Tissue culture provides a new pathway for the breeding of superior varieties and the selection of new cultivars of geraniums.

Cultivation Methods for Geraniums

1. Temperature control: The most suitable temperature for geraniums is 10-20°C, which means spring and autumn are the most suitable seasons. Winter is too cold and summer is too hot. Therefore, in summer, be sure to prevent exposure to direct sunlight and place them in a cool spot. In winter, indoor temperatures should not fall below 0°C, otherwise they will suffer frost damage. If there is no heating equipment, turning on a 200° large light bulb in a small room can also have a certain antifreeze effect.

2. Water control: Geraniums should not be overwatered. If you find the roots of a geranium rotting, it may be due to excessive watering combined with relatively hot and humid weather. Keep the watering frequency to once every two or three days, and each time water generously to ensure thorough watering.

3. Soil selection: Geraniums are suited to sandy soil. Mixing some sandy soil into the soil bought from a flower market is more beneficial for geranium growth.

4. Weather effects: Strong winds will snap geraniums, and heavy rain will cause the root system of geraniums to be soaked by rainwater, resulting in root hypoxia and subsequent rot.

6. Fertilizer control: Applying too much fertilizer at once will cause dehydration in geraniums. If too much fertilizer is applied, for example excessive nitrogen fertilizer, it will cause the plant to grow excessively and not bloom. After over-fertilizing, watering more frequently can alleviate the symptoms.

7. Light conditions: Sufficient sunlight helps geraniums bloom, but when temperatures are too high, direct sunlight is not suitable. In spring and autumn, expose them to more sunlight. In summer, pay attention to the temperature; when it is too high, avoid exposing geraniums to light.

Precautions for Geraniums

January: Place in a sunny spot to prevent damage. When the weather is clear, water, preferably at noon. Do not use snow water or cold water.

February: Apply a thin liquid fertilizer once every 2 weeks, appropriately increase watering, and pay attention to ventilation on nice days.

March: Cutting propagation can be combined with pruning. Select cuttings from mother plants that bloom frequently, are of pure variety, and grow well, cutting healthy one-year-old branches, each 4-6 cm long with 2-3 nodes. Remove the lowest leaf and place in a cool spot for a day. After the cut end dries, insert. Choose sandy soil on high, dry terrain with good drainage, deep-plow and level it to make a seedbed, then mix 60% yellow mud with 40% rice husk ash and spread it on the seedbed for cutting.

April: Continue cutting propagation. For seed propagation, since the seeds are not large, the soil covering should not be too deep. After sowing, keep warm at 20-25°C, and germination occurs about 2 weeks after sowing. After cuttings have rooted, they should be potted promptly. Use a mix of leaf mold, rice husk ash, and garden soil in equal parts, plus some bone meal and phosphorus-potassium compound fertilizer. April to June is the full blooming period, and a thin liquid fertilizer can be applied once a week. In late April, they can be moved outdoors for cultivation. When seedlings are 12-15 cm tall, pinch off the growing tips to encourage side branch formation.

May: After flowers fade, promptly remove spent blooms. When cutting, it is best to cut 3-4 cm from the first leaf below the flower stalk to reduce nutrient consumption and promote new flower growth. Do a good job with fertilizing, watering, and pest and disease control. Seeds mature 40-50 days after flowering and should be collected promptly, dried, and stored.

June: As the flowering period ends, short pruning should be carried out to make the plant short, sturdy, full, and attractive. Do not water or fertilize for one week after pruning, so the cut ends shrivel and avoid rotting from moisture. By late June, the plant enters a semi-dormant state. It should be placed in a shaded, cool area, watering should be controlled, and fertilizing stopped.

July: Water mainly in the early morning each day, with supplementary watering in the evening, watering when dry. After rain, drain promptly, and absolutely avoid water accumulation in the pot.

August: Autumn cutting propagation can be carried out. Geraniums grow rapidly and need repotting every year, replacing the soil and heavy pruning, leaving about 10 cm at the base. Also appropriately trim some longer fibrous roots, and properly remove excess shoots from the upper part.

September: Continue cutting. They grow rapidly, so apply a thin liquid fertilizer about once every 10 days. When fertilizing, do not splash it onto the leaves.

October: Flowering begins and continues until June of the following year. Pay attention to placing them in a wind-sheltered, sunny spot to prevent cold air intrusion. In late October, move into a greenhouse and pay attention to ventilation.

November: Ensure sufficient sunlight, control watering, fertilize promptly, strengthen ventilation, and prevent pest and disease occurrence.

December: Room temperature must not be below 5°C. Do not water unless dry. Promptly remove spent flowers and dead leaves.

Cultivation Methods and Precautions for Geraniums

Pelargonium, also known as fish geranium, zonal geranium, and pelargonium, belongs to the family Geraniaceae and is a genus of flowering plants that includes about 230 species of perennial succulent, subshrub, or shrub plants. Geraniums are native to southern Africa and widely cultivated around the world.

Geraniums are perennial evergreen herbaceous or subshrub flowering plants of the genus Pelargonium in the family Geraniaceae. Native to southern Africa, they are widely cultivated around the world. Geraniums have a long flowering period and strong adaptability to the environment. Their plant size is suitable for home pot cultivation, and they are easy to propagate, making them very popular. They are one of the common potted flowers in homes and also a commonly used flower for flower beds in warm winter regions. Geranium flowers cluster together, and the large inflorescences resemble hydrangeas, with vivid colors. They can be used for indoor decoration and also for arranging spring flower beds and venues. Below is a detailed introduction to how to grow geraniums:

1. Soil Selection for Geranium Cultivation

For potted geraniums, the growing medium can be a mix of 4 parts leaf mold, 3 parts garden soil (or peat soil), 2 parts river sand (or perlite), and 1 part organic fertilizer. It can also be prepared by mixing fine sandy soil, leaf mold, perlite, and organic fertilizer. Potted geraniums need repotting in autumn.

2. Fertilization Methods for Geranium Cultivation

During the growing period, apply liquid fertilizer once every 10-15 days. In the vigorous growth seasons of spring and autumn, apply liquid fertilizer once every 7-10 days. Before bud formation, mainly use nitrogen fertilizer; after bud formation, mainly use phosphorus and potassium fertilizer, with a concentration of 0.1%-0.2% being appropriate. If the winter room temperature is relatively high and growth has not stopped, fertilizer should also be applied. During the high-temperature period in summer, the plant is in a semi-dormant state and fertilization should be stopped. Because its stems and leaves have fine hairs, rinse immediately with clean water after fertilizing.

3. Watering Methods for Geranium Cultivation

Watering should be appropriate, preferring dry over wet. During the peak growth seasons of spring and autumn, provide sufficient water to keep the potting soil consistently moist, but not waterlogged. On low-temperature cloudy days, generally do not water or fertilize. In summer, water less. In northern regions, the high-temperature season coincides with the rainy season. During this period, the plant's root system is relatively weak, so avoid excessive rainwater irrigation. Consecutive rainy days will cause root rot, so place them in a shaded, cool, high, dry, and well-ventilated area. In winter, water according to indoor temperature; water less when room temperature is low and more when it is high. Geraniums have strong drought tolerance and will not die from drying out after several days without water, but old leaves will turn yellow and drop.

Water by the principle of "see dry, see wet." Too-wet potting soil easily causes root rot, while too-dry potting soil easily causes leaves to yellow. From June to July, they enter a semi-dormant state, and watering should be strictly controlled. In summer, spray water frequently to cool down and keep the potting soil moist, and also pay attention to ventilation and light. In winter, restrict watering.

4. Temperature Requirements for Geranium Cultivation

Geraniums prefer warmth, dislike high temperatures, and fear cold. The suitable temperature for geranium growth is 15-25°C, and in winter, indoor temperatures should be maintained at 10°C. Below 3°C, they are susceptible to cold damage, though some varieties can tolerate low temperatures of 0°C. In summer, when temperatures exceed 35°C, they enter a semi-dormant state.

5. Light Requirements for Geranium Cultivation

Under direct sunlight, they grow robustly with dark green leaves, short internodes, and an attractive plant shape. However, when summer light is too strong, 30%-50% shading is needed. For home cultivation, in autumn, winter, and spring, they should be placed in locations with direct sunlight. When blooming, they can be moved indoors for appreciation, but after flowering they should still be placed in a lighted area. They prefer abundant sunlight, and without enough light they will not bloom. During the flowering period, avoid direct strong light, otherwise the petals will scorch and easily drop.

Rotate the pot once a week to ensure even light exposure on the leaf surface and maintain a balanced plant shape. In summer, place in a cool area and avoid exposure to the scorching sun. In winter, room temperature should not be below 5°C, with full light exposure.

6. Pest and Disease Control for Geranium Cultivation

The main diseases of geraniums include mosaic disease, crinkle disease, chlorosis, gray mold disease, root rot, and bacterial wilt. The main pests include whiteflies, caterpillars, and small plume moths. To control mosaic disease, eliminating aphids is of great significance, and other nearby parasitic plants should also be cleared. To control small plume moths, spray with 90% trichlorfon at 1000 times dilution.

7. Precautions for Geranium Cultivation

(1) To control plant height and achieve the goal of large, brightly colored flowers, in addition to selecting dwarf geranium varieties, the application of growth regulators is very important. Two weeks after geraniums are planted in 12 cm or 15 cm pots, spray the leaf surface with 0.15% chlormequat or daminozide once a week for 2 consecutive weeks, with 14-18 hours of daily light. This can effectively control the height of geraniums and provide high-quality commercial potted flowers.

(2) They are relatively tolerant of dryness and afraid of waterlogging. Too much water easily causes plant death, and under high temperature and high humidity, the roots easily rot. They require well-drained, loose soil rich in organic matter. The flowering period is long, with the full blooming period from April to June. If given relatively high temperatures in winter and managed properly, they can bloom continuously from September in autumn to June of the following year.

8. Propagation Methods for Geranium Cultivation

Geraniums are commonly propagated by seed and cuttings, and can also be propagated by tissue culture.

(1) Seed propagation: Single-petaled geranium varieties easily set seed, and seeds can be sown immediately after collection. If sowing is to wait until the weather is cooler, first dry the seeds and store them in a paper bag. At 20°C, germination occurs in about 7-10 days. After seedling separation and transplanting, when seedlings grow to 5-7 cm, plant them in 10 cm flower pots, and they can bloom the following spring.

Because seedlings grown from seed have relatively poor plant characteristics and flowering quality, seed propagation is usually not used.

(2) Cutting propagation: Cuttings can be taken at any time except when the plant is in a semi-dormant state from June to August. However, spring and autumn are best. Cuttings should preferably be taken from mother plants that bloom consistently, bloom frequently, are of pure variety, and are free of pests and diseases. Both the tender shoot tips and the tender stems below can be used as cuttings, but the top portion is best, as it has vigorous growth and roots quickly. After cutting the cuttings, soak in 100 mg/kg indolebutyric acid for 5-10 seconds, then dry for half a day. After they wilt, insert into a sand bed or a substrate of perlite and peat mixed 1:1. After thorough watering, cover with a small arched shelter, and shade when sunlight is strong. Maintain a temperature of 15-20°C. Roots form 2-3 weeks after insertion, and transplant when roots are 3-4 cm long.

(3) Tissue culture propagation: Use MS medium, add 10 mg/kg indolebutyric acid and kinetin to promote callus and adventitious bud formation from explants, and use 100 mg/kg indolebutyric acid or indoleacetic acid to promote rooting. Tissue culture propagation is mainly used for breeding superior varieties and selecting new cultivars.

When Is the Best Time to Repot Geraniums

Geraniums are easy to cultivate and have a long flowering period. Flowers can be single or double, with colors including red, white, pink, and purple. The leaf shape is attractive, and the large inflorescences resemble hydrangeas with vivid colors, making them an excellent variety for balcony flower growing.

Because they grow fast and bloom profusely, they need repotting once a year. Early spring is the blooming season, and after blooming in June, they enter an unfavorable hot and humid season and a semi-dormant state. The best time for repotting is from late August to early September. Before repotting, prune to remove overly dense branches, slender branches, pest- and disease-damaged branches, and leggy branches. Keep 3-5 evenly distributed main branches, then shorten the main branches and side branches, leaving only 3 side buds on each side branch, so that the branches are evenly distributed, compact, and the plant shape is full and short.

Use bone meal and other materials as base fertilizer, and water 2 days after planting. In November, move indoors to a sunny spot, and at the end of April move to the balcony, avoiding exposure to the scorching sun. During the growth and flowering period, apply a thin liquid fertilizer once a week. In July-August, stop fertilizing and water less. At other times, also control watering, and only water when the potting soil turns pale.

How to Prevent Geranium Root Rot

Geranium, also known as fish geranium, zonal geranium, hydrangea geranium, and pelargonium, is a subshrub or perennial herbaceous plant of the genus Pelargonium in the family Geraniaceae. It is covered with fine soft hairs throughout and has a distinctive scent.

Native to southern Africa, it is now widely cultivated around the world. It prefers a cool climate, with a suitable temperature of 10-25°C. It can tolerate low temperatures of 0°C, and enters a semi-dormant state during high-temperature summer periods. It prefers sufficient light, and without enough light it will not bloom. During the flowering period, avoid direct strong light, otherwise the petals will scorch and easily drop. It is drought-tolerant and averse to waterlogging; excessive water can be fatal. It prefers well-drained, loose soil. The full blooming period is from April to June, and the flowering period is long. If given relatively high temperatures in winter and managed properly, it can bloom continuously from October in autumn to June of the following year.

Spring and autumn are the vigorous growth periods for geraniums, and watering can be appropriately increased. When summer temperatures are high, geraniums enter a semi-dormant state, and watering must be strictly controlled. It is sufficient that the potting soil is not too dry. At the same time, watering in the morning and evening is preferable. Never water at noon when soil temperature is relatively high, otherwise it will very easily cause root rot. On rainy days, shelter from rain. During the "plum rain" season, never let the potting soil remain overly moist for long periods.

To prevent geranium root rot, in addition to paying attention to watering, also choose sandy loam rich in humus with good drainage and aeration. Heavy clay soil has poor structure and poor drainage and aeration, and should not be used for planting geraniums.

When transplanting geraniums, the shovel should not be too close to the roots, to avoid damaging the root hairs. Keep the roots as intact as possible; if the root hairs are damaged, they are most prone to mold and rot after watering.

To keep geraniums from root rot, timely pest and disease control is also needed. Nematodes are a common pest of geraniums. When the temperature is 25-30°C and humidity is around 40%, it is the most suitable time for nematodes to invade geranium roots. When damage is severe, the root system falls off segment by segment, and may even rot entirely.

How to Cultivate Large-Flowered Geraniums?

Large-flowered geraniums prefer warmth, humidity, and sufficient sunlight. They are afraid of waterlogging and frost, are somewhat drought-tolerant, and also have a certain flood tolerance. They are not particular about soil, but grow well in slightly acidic, fertile soil. If the temperature remains at 18-25°C and sufficient light is provided, large-flowered geraniums can bloom year-round. If light or fertilizer is insufficient, branches will become leggy, with few or no flowers. In home cultivation, they enter a semi-dormant state during the high temperatures of June to August in summer. In northern home cultivation, in winter they should be placed on a sunny indoor balcony, maintaining 15-20°C. After the weather stabilizes in April, move them outdoors. During the growing period, continuously spray water on the leaves.

In daily management, create a suitable growing environment according to the habits of large-flowered geraniums. Although they are highly adaptable, to keep them blooming profusely with lush foliage year-round still requires careful management, especially ensuring daily light is no less than 4 hours. First, always pay attention to ventilation, ensure humidity, and do a good job of cold protection in winter. Second, large-flowered geraniums grow quickly and their branches have a strong phototropic tendency. Rotate the flower pot every 3-5 days to prevent uneven crown growth, and also pay attention to supplementing with compound fertilizer.

Third, the flower stems of large-flowered geraniums emerge from the growth point at the top of the stem. Therefore, only with more pruning can the plant shape be full and symmetrical, with abundant flowers, and leggy growth prevented. Note that they should be protected from death from soft rot under conditions of sustained high temperature, high humidity, and poor ventilation, and from cold damage when temperatures are below 2-3°C. The leaves of large-flowered geraniums can secrete antibiotics and have extremely strong resistance to pests and diseases.

How to Grow Geraniums Well in Summer and Winter?

Geraniums have beautiful flowers and beautiful leaves. In particular, their leaves closely resemble a shield, which makes people feel curious, but some people find the smell of the leaves unpleasant. The characteristics of geraniums are many flowers and a long flowering period.

Geraniums have two prominent problems. First, flowers or leaves easily drop in summer because they encounter heat and enter a semi-dormant state. Therefore, at this time, control watering, and even more so do not fertilize. Move them to a cool place and spray water around them to create a cool environment. After heavy rain, drain promptly to prevent water accumulation from causing root rot and leading to leaf drop and yellowing.

Another point is that for overwintering, the temperature should be controlled at around 12°C, and they should be placed in a sunny spot for the winter. When the plant grows to 15 cm, pinch off the growing tips to encourage more side branches, more flowers, and a graceful plant shape.

Control Methods for Geranium Leaf Spot Disease

[Symptoms] In the early stage of the disease, chlorotic spots appear on infected leaves, and afterward the lesions gradually expand to form relatively large round spots. The lesions are dark brown with concentric rings. In the late stage of the disease, a dark green mold layer appears on the lesions, which consists of the pathogen's conidia.
[Occurrence pattern] The pathogen overwinters as mycelium in diseased residues or diseased tissues. When environmental conditions are suitable, it produces conidia. Conidia spread through wind and rain to infect and cause damage. During the growing season, conidia can repeatedly infect plants. The pathogen can directly invade through stomata, lenticels, or the epidermis, forming a primary infection. After an incubation period of 2-3 days, lesions appear, and after 3-4 days conidia are produced, which then undergo multiple repeated infections through airflow and rainwater.

When geraniums enter the vigorous growth and flowering period, the basal leaves begin to age, and the pathogen accumulates on the plant. At this time, if there is continuous rainy weather with relative humidity greater than 70%, the disease begins to occur and spread. Therefore, the timing of the arrival of the rainy season, the number of rainy days, and the amount and distribution of rainfall all affect the outbreak and spread of this disease.

[Control methods] (1) Reduce sources of infection. Promptly cut off diseased leaves when found and destroy them together with diseased leaves. (2) Chemical control. In the early stage of the disease, spray with 1:1:200 Bordeaux mixture, or 50% thiram wettable powder, or 65% zineb wettable powder at 600-800 times dilution, once every 10-15 days, spraying 2-3 times.

Key Points for Propagating Geraniums by Cuttings

Geraniums are mainly propagated by cuttings. Cuttings taken in April-May can bloom in autumn; cuttings taken in September-October bloom in winter and spring. The stems are tender, juicy, and hollow, and rot very easily after cutting. The thicker the stem, the higher the rot rate. Therefore, the following points should be noted when propagating by cuttings:

(1) Cutting time.

Geranium cutting propagation is usually best in spring from April to May or autumn from mid-to-late September, when temperatures are suitable. In summer, temperatures are high and humidity is high, so cuttings easily rot. In winter, temperatures are low and rooting is relatively slow.

(2) Cutting selection and treatment.

Select cuttings from mother plants that bloom consistently, bloom frequently, are of pure variety, and are free of pests and diseases, cutting vigorous tender shoot tips and tender stems below, 7-10 cm long. After cutting the cuttings, do not insert them immediately. Let them dry for at least a day and night, and insert only after the cut ends have dried. Alternatively, pinch off the growing tips on the mother plant intended for cuttings in advance. After new side branches emerge, cut from the base of the new side branches close to the mother plant. Such cuttings have smaller cut ends, are solid rather than hollow inside, easily form callus, root relatively quickly, rarely rot, and have a high survival rate.

(3) Cutting and post-cutting management.

For the cutting substrate, clean river sand, vermiculite, perlite, and similar materials can be used. The insertion depth should be about 1/3 of the cutting length, and large leaves on the cutting should be trimmed off, leaving only 1/2 of a small leaf to reduce water evaporation. After inserting, water thoroughly, and first place in a cool area, avoiding direct sunlight. Maintain the substrate temperature at 15°C. Roots form in about 1 month. After rooting, pot them promptly.

Propagation Methods for Geraniums

(1) Seed propagation can be carried out in spring or autumn, with indoor pot sowing in spring being preferable. The suitable germination temperature is 20-25°C. Geranium seeds are not large, so after sowing the soil covering should not be deep, and they germinate in about 14-21 days. If sown in autumn, they can bloom the following summer. Seedlings grown from seed propagation can be selected to breed excellent intermediate-type varieties.

(2) Cutting propagation can be carried out at any time except when the plant is in a semi-dormant state in June-July. Spring and autumn are preferable. In summer, high temperatures cause cuttings to easily turn black and rot. Cuttings are 10 cm long, with the top portion being best, as it has vigorous growth and roots quickly. After cutting, let the cut end dry for several days until a thin film forms, then insert into a sand bed or a mixed substrate of expanded perlite and peat. Be careful not to damage the stem bark of the cutting, otherwise the wound will easily rot. After cutting, place in a semi-shaded area and maintain a room temperature of 13-18°C. Roots form 14-21 days after insertion, and when roots are 3-4 cm long they can be potted. During the cutting process, soaking the base of the cuttings in 0.01% indolebutyric acid solution for 2 seconds can improve the survival rate and rooting rate of cuttings. Generally, cutting-grown seedlings bloom after 6 months of cultivation, that is, cuttings taken in January bloom in June; cuttings taken in October bloom in February-March of the following year.

(3) Tissue culture propagation: Geraniums can also be propagated by tissue culture. Using MS medium as the basic medium, add 0.001% indoleacetic acid and kinetin to promote callus and adventitious bud formation from explants, and use 0.01% indoleacetic acid to promote rooting.

What Are the Cultivation Methods and Precautions for Geraniums

The leaves of geraniums are palmate with long petioles, mostly serrated leaf margins, and have relatively deep ring-like markings on the leaf surface. The corolla has five petals, and the inflorescence is umbel-shaped, beautiful in appearance. Therefore, they are often grown in gardens and as home potted plants, not only beautifying the living environment but also effectively purifying the air. So what are the cultivation methods and precautions for geraniums in daily life? Let us take a look together below!

Cultivation Methods for Geraniums: Water

Geraniums are native to southern Africa and are plants that do not like too much water. Therefore, during cultivation, never water geraniums too much. If watered excessively, it will cause the roots of geraniums to rot. If they grow long-term in such a waterlogged environment, it will affect their growth and lead to death. Therefore, when growing geraniums, it is enough to water them once every two to three days, but each watering should be sufficient.

Cultivation Methods for Geraniums: Fertilizing

Applying an appropriate amount of fertilizer is also a key point in growing geraniums. Too much fertilizer will cause dehydration in geraniums and affect their normal growth, but if you do not fertilize them for a long time, it will also cause insufficient nutrients. The amount of fertilizer for geraniums is directly related to the quality of the soil, the size of the flowers, and the size of the flower pot. Therefore, when purchasing, it is best to ask the shopkeeper to understand the required fertilizer amount and frequency.

Cultivation Methods for Geraniums: Temperature

Geraniums prefer warm, humid, and sunny environments. The most suitable growing temperature is between 10 and 20°C, which is the temperature of spring and autumn. Therefore, protective measures must be taken in both winter and summer. In winter, place them in an environment where the temperature is not lower than 0°C to avoid frost damage. In the hot summer, move them to a cool place and avoid exposure to the scorching sun.

Conclusion:The above are some cultivation methods for geraniums introduced to you. Geraniums are very easy plants to grow. As long as you understand their growth habits and give them a little care in daily life, they will bloom with beautiful and brilliant flowers.
