How to Grow Calliandra? Detailed Guide to Cultivation Methods and Precautions

Although Calliandra is beautiful and everyone especially loves its flowers and wants to grow a pot at home, they find it is not so easy to grow and requires certain skills, especially since various problems arise during cultivation. So the editor will now introduce its cultivation methods and precautions.

How to Grow Calliandra

1. Potted cultivation: For home potting, it is best to choose garden soil mixed with some river sand as the potting soil, and place it on a south-facing balcony for growing and viewing. The optimum growing temperature is 23°C to 30°C. During overwintering, keep the temperature at 15°C to 18°C and shelter it from wind to reduce leaf drop. Normally, water when the top 1 cm of the potting soil surface is dry. In winter, water when half of the potting soil is dry. Apply a compound fertilizer once a month from spring to autumn.

2. Water and fertilizer: Young Calliandra plants need more water, so attention should be paid to irrigation during the growing period. Potted plants are more prone to drought and water shortage, with leaves appearing wilted, so attention should be paid to replenishing water.

For fertilization, natural organic fertilizer or compound fertilizer can be used, applied once a month, with more phosphorus and potassium fertilizer applied during the flowering period. The cultivation site needs sufficient sunlight; flowering is poor in shaded places.

Calliandra Cultivation Methods and Precautions

I. Cultivation Methods

1. Soil: To grow Calliandra, you can choose a mixed soil of garden soil and river sand as the substrate. The soil should be deep, fertile and well-drained, and some base fertilizer can be added.

2. Light and temperature: In terms of light and temperature, Calliandra likes a warm and sunny environment. The suitable growing temperature is 20°C to 30°C. It is slightly intolerant of cold, and the overwintering temperature in winter should be kept above 15°C, and it needs to be protected from cold wind.

It relatively likes sunlight, and sufficient light should be maintained during the growing period. Insufficient light will cause poor flowering.

3. Water and fertilizer management: Calliandra has a relatively large demand for water and fertilizer. During the growing period, it needs more watering. Potted plants are more prone to water shortage, so water needs to be replenished frequently to keep the soil moist. Generally, watering can be done after the soil surface dries. For fertilization, some compound fertilizer can be applied, once a month during the growing period. During the flowering period of Calliandra, more phosphorus fertilizer and potassium fertilizer can be applied to make the flowers more colorful.

II. Precautions

1. Pruning: Calliandra plants will grow very large. When the small tree reaches more than 2 m in height, pruning can be carried out. The main branches of Calliandra can be cut off to promote new branches and make the crown fuller. Usually, attention should be paid to pruning the plant shape to make the tree shape beautiful, and dead branches and diseased branches that affect the healthy growth of Calliandra should also be cut off.

2. Pests and diseases: The main disease suffered by Calliandra during growth is canker disease. When Calliandra develops canker disease, it can be treated by spraying with a 800-fold dilution of 50% Tuzet. The main pests are longhorn beetles and psyllids. Insecticidal agents can be used to kill the insects, or environmentally friendly methods can be chosen to eliminate the insects.

Calliandra Propagation Methods

1. Propagation by sowing

The flowering period of Calliandra is August and September each summer, and the best seed collection period is October. Select plump, complete and healthy seeds and store them in a dry and ventilated environment. Wait until the following spring to sow.

Before sowing, the seeds need to be soaked in clean water at 60 degrees, changing the water once a day for three consecutive days, then taken out. Keep them moist for germination. Sow the seeds in moist soil, and they will germinate in about one week.

2. Propagation by cuttings

In Calliandra cultivation, cutting propagation is generally chosen. In spring, cut healthy branches about 20 cm long, remove dead leaves, and insert them into a moist sandy soil substrate. It is best to keep the temperature between 15——30°, and just pay attention to shading and moisture retention.

Solutions to Common Pests and Diseases of Calliandra

1. Canker disease: Spray with a 800-fold dilution of 50% Tuzet.

2. Pests: The biggest pests of Calliandra are longhorn beetles and psyllids. To kill longhorn beetles, use 1 kg of kerosene plus 50 g of 80% dichlorvos emulsifiable concentrate. For psyllids, spray with a 1500-fold dilution of 40% dimethoate emulsifiable concentrate.

It seems that if you want to grow a beautiful pot of Calliandra, it is like going through stages, encountering various problems that all need to be solved one by one, otherwise it will affect its growth and thus affect its beauty. Especially when pest and disease problems appear, they cause great harm to it. We must do a good job of prevention to avoid similar problems.
