1、 Reasonable light exposure

Reason: iris is suitable for growing in a semi shady environment and can't stand the irradiation of strong light. Once exposed to strong light, it may burn the leaves, cause the leaves to turn yellow and dehydrate, and then fall down

solution: when you grow iris, you must pay attention to good light. After the strong light, remove the iris to the shade, maintain proper shade, spray the plants properly, increase the humidity of the air, and promote the plant recovery. p>

2、 Natural metabolism

After a natural growth cycle, the iris will fall after a natural growth cycle

Solution: This is a normal phenomenon and belongs to natural metabolism. In this case, no more treatment is needed, just continue to maintain

3、 Adjust watering

Reason: in the process of maintenance, watering is also very important. Too little watering will lead to drought and water shortage, causing leaves to turn yellow and fall off. Watering too much will lead to ponding at the root and rotten roots and leaves

Solution: Iris doesn't need too much water and doesn't like the humid growth environment, but it can't lack water, so it should be watered according to the growth needs, but not too much

4、 Pest control

Cause: poor maintenance may breed diseases and insect pests, which will cause diseases and insect pests, cause problems on leaves, and lead to yellowing and falling

Solution: pay attention to the maintenance method, do a good job in ventilation treatment, and treat the diseases and pests in time
