How to deal with yellow leaves in orchids

When orchids have yellow leaves, they should be improved by light, temperature, watering and fertilization. Receive 6-8 hours of sunlight every day to avoid strong direct light exposure. Keep the growth temperature at 18-25 degrees, keep the basin soil slightly moist during each watering, and apply mature organic fertilizer every half a month during the growing period.

First, keep enough light

When the orchid has yellow leaves, it is necessary to maintain sufficient light. For example, put it in a sunny position every day and receive 6-8 hours of sunlight. When the light is relatively strong, it is necessary to properly deal with shading and prohibit exposure to the sun.

Keep a warm environment

When the orchid leaves are yellow, keep the environment warm. Because orchids like to grow in a warm environment, the most suitable temperature for growth is between 18 and 25 degrees. Maintain normal maintenance in spring and autumn, cooling measures in summer and heat preservation measures in winter.

Third, rational watering

When the orchid leaves are yellow, it should be watered reasonably. Orchids like to grow in a slightly moist environment, so they must be properly watered every time and keep the basin soil slightly moist. Do not water too much, resulting in serious root rot in stagnant water.

IV. Rational fertilization

When the orchid has yellow leaves, it is necessary to apply fertilizer reasonably. During the growth period of orchids, mature organic fertilizer can be applied every half a month, phosphorus and potassium fertilizer can be added before flowering, foliar fertilizer of potassium dihydrogen phosphate should be applied once a month, phosphorus and potassium fertilizer should be applied mainly and nitrogen fertilizer should be used as auxiliary fertilizer before overwintering.
