1、 Natural aging

1. Reason: with the continuous growth of orchid itself, it will metabolize itself. Old leaves will gradually become thinner, softer and yellow. At the same time, new leaves will grow. This is a natural process

2. Treatment method: at this time, there is no need for special treatment, as long as it is cured in a normal way. After a period of time, its old leaves will shrink and fall off, and the new leaves will grow bigger and bigger, so as to replace the old leaves

2、 Insufficient moisture

1. Reason: its growth needs water support. If it is not watered for a long time, it will not be able to absorb enough water to maintain normal growth. At this time, its blades will become soft and thin

2. Treatment method: at this time, pour some water into the plant material first, wet and pour through the plant material, but do not let water accumulate in it. After that, slightly increase the watering frequency, and timely spray water around the plant with a watering can to increase the humidity. It will recover in a period of time

3、 Insufficient light

1. Reason: it is a shade loving flower, but it is not resistant to long-term shade. If the maintenance environment is too dark and there is no light, it will grow poorly and the leaves will become soft and thin

2. Treatment: put the plant in a ventilated and bright place to supplement the light. After a period of time, it will recover
