What is the cause of the yellowing of the leaves of the gentleman s orchid and how to treat it

In general, there are the following reasons and solutions.

Reason 1: Apply raw fertilizer or thick fertilizer.

Reason 3: Treatment method:

Control watering immediately.

Avoid rain. Stop fertilizing.

Loosen the soil frequently, so that the soil increases the oxygen content, improves the absorption capacity of the root system, and promotes the growth of plants.

Water in moderation first.

In the case of high and dry temperatures, it is more important to pay attention to balanced watering.

After the orchid gradually recovers its vitality, it can be transferred to normal water and fertilizer management.

Always keep the potting soil moist and loose.
