What's up with the dried leaves of petunia?

1. Unsuitable soil

1. Reason: If the soil used is not suitable for the growth of petunia, it will easily cause its leaves to dry up. Specifically, slightly acidic soil is best for it. Alkaline soil may cause its leaves to fall off.

2. Measures: In this case, the soil needs to be changed in time. It is best to use acidic soil, but neutral soil can be used if this is not possible.

2. Iron deficiency

1. Reason: Iron plays a very important role in the growth of petunia. Lack of iron in watering can cause leaves to dry out.

2. Measures: Iron needs to be supplemented in time. It is most appropriate to use some iron-rich fertilizers, such as alum fertilizer water.

3. Humidity is too low

1. Reason: If petunia is kept in a very dry place for a long time, its leaves will easily dry up.

2. Measures: The first task is to increase the humidity of the surrounding environment. Especially when the weather is dry, proper watering and spraying are very necessary tasks.

4. Too much light

1. Reason: If petunia is exposed to strong light for a long time, its leaves may dry up and fall off.

2. Measures: Move it to a cool place. Semi-shaded places are more suitable for its growth. Especially the strong light at noon, be sure to avoid it.
