The light is uncomfortable. Plants lack oxygen and are placed in a ventilated and dry place. Begonia flowers don't like closed and stuffy environment, but begonia flowers like ventilated environment. If the leaves of begonia flowers are dry and the ambient air is not smooth, potted begonia flowers should be placed outdoors and in a ventilated place on the balcony immediately.

Solution:

1, often loosen the soil, control watering, and avoid spraying in heavy rain.

2. Gradually increase water and fertilizer and change pots in time.

3, water frequently, suspend fertilization, sprinkle some seeds in the pot, pull them out after emergence, so as to consume fertilizer in the pot and restore the normal growth of flowers and trees.

Soak the grass in water and apply some ferrous sulfate, and the leaves will return to normal.
