Sufficient sunshine Spring is the peak season for the growth of young trees of the rich trees, so it is necessary to ensure sufficient light and water and fertilizer supply. When the outdoor temperature is stable above 15℃, it can be decided whether to turn over the pots according to the growth, and move the potted plants to the semi-shade of the balcony or the bright indoor light for maintenance. After the temperature rises in late spring, plants should be moved to a sunny place for maintenance in the morning and evening.

Replenish water. Usually use dry and wet water to keep the soil moist, and often spray water to increase the air humidity.

Fertilize in spring, reduce fertilization, or even not fertilize. If the leaves are found to be yellow, foliar fertilizer should be sprayed in time, and urea 500 times 1~2 times should be sprayed on the leaves to supplement nutrition.

Cultivation and maintenance methods in summer

Shading and watering the rich trees like high temperature, but they can't stand the scorching sun. When the weather is hot in summer, plants should be maintained in a semi-shady place, watered in time to ensure moisture, properly sprayed with water to increase air humidity. Stop fertilizing in hot season.

It is the best season to breed Nostoc flagelliforme in June-July. Cutting propagation can be used. Select 10~ 15 cm, leave 2~3 leaves at the top, and it can be inserted into the soil to take root and become seedlings in about 30 days.

Cultivation and maintenance methods in autumn

In autumn, plants should ensure sufficient light and timely water and fertilizer. When the temperature drops, plants should be moved to a bright place indoors for maintenance. The maintenance in spring and autumn is similar. Please refer to the spring maintenance method for details.

Cultivation and maintenance methods in winter

Warm-rich trees are not cold-tolerant, and can safely overwinter when the winter temperature is above 1 1℃. If it is below 5℃, plants are easily frostbitten and defoliated.

Light and moisture ensure sufficient light in winter, which can be supplemented manually if it is cloudy. When the temperature is high at noon, spray it everywhere to increase the air humidity. Adult plants need to be watered in a controlled way. When they are dry, they will get wet, but they should be watered frequently.
