The cultivation method and precautions of colorful iron should be 15cm diameter flowerpot.

Soil: slightly acidic sandy soil should be selected, which should be loose and permeable, fertile, rich in humus and good drainage. Temperature: the suitable growth temperature is about 20-28 ℃, and anti-freezing measures should be taken when it is lower than 10 ℃. Light: like light but can not be exposed to the sun. Watering: the method of alternating dry and wet, no dry, no watering, watering thoroughly, reducing the watering frequency in winter. Fertilization: fertilize about every half a month, nitrogen should not be too much. Pruning: remove yellow leaves, withered leaves and old and weak leaves in time.

Soil flowerpots

Colorful iron is very fond of growing in slightly acidic sandy soil, so when potted, we must choose nutritious soil that is loose and breathable, fertile, rich in humus and good drainage, so as to promote the healthy growth of colorful iron. During this period, we should pay attention not to use clay for planting. As for the choice of flowerpots, it is mainly based on the size of colorful iron plants. Generally choose a flowerpot with a diameter of 15cm.

2. Suitable temperature

The suitable growth temperature of colorful iron is about 20-28 ℃. Generally, in winter, when the temperature is below 10 ℃, corresponding anti-freezing measures should be taken to ensure that the temperature should not be lower than 5 ℃. In the process of breeding, the temperature should not be too high or too low. The suitable temperature is conducive to the growth of colorful iron, so we can choose to breed indoors with better heat preservation effect.

Third, reasonable lighting

Colorful iron is a plant that loves light, but it is afraid of exposure in the hot sun, so it can be cultured in a semi-shaded and ventilated environment, during which it can be properly exposed to a little sun. therefore, special attention should be paid to shading the colorful iron in summer, but the sun care is not very strong in the morning or evening in winter. A little exposure to the sun can promote the healthy growth of colorful iron.

Fourth, late watering

Colorful iron is more able to withstand a short period of drought and wet stains, can be watered alternately when watering, can also choose not to water when not dry, but the principle of watering thoroughly, a small amount of foliar water can be sprayed in the morning and evening, so as to enhance the humidity in the air, and appropriate watering should be reduced in winter to prevent freezing damage and excessive stagnant water from causing rotting roots.

5. Apply fertilizer

Colorful iron can be fertilized every 15 days, during which some water-soluble fertilizer or rotten cake fertilizer can be applied to ensure that nitrogen, phosphorus and potassium are more comprehensive, nitrogen should not be too much, and it is very easy to cause the color of leaves to be dimmed. Colorful iron, which is generally cultivated for several years, can be fertilized every 7 days, and a small amount of fertilizer should be applied more and more to avoid some fertilizer damage.

6. Pruning branches and leaves

When yellow leaves appear during the growth period of colorful iron, withered leaves and old and weak diseased leaves, it is necessary to prune branches and leaves properly. if there are more healthy and luxuriant branches and leaves, they can be transplanted and propagated by cuttings. it is beneficial to promote the growth and development of colorful iron.
