When the leaves of Begonia appear curled, it may be that the water is not given enough, that is, half of the water is absorbed, and the places underneath that should be absorbed cannot be absorbed. It is also possible that too much nutrients are applied, far exceeding the requirements. Or aphids or leaf rollers are spreading unchecked. If the leaves begin to turn yellow and wither, it may be that they cannot withstand the sun.

1. What is the reason for the curled leaves?

1. Half-watering: When giving it water, it is not given enough water, which is the situation of half-watering. The roots are all underneath it, and water is poured from the top, but it doesn't seep down to the bottom. Naturally, the places underneath that should be absorbed can't absorb it, so it can't drink water. If the water supply is insufficient, the leaves will begin to curl. This situation often happens. When adding water, estimate the water requirement based on the size of the plant at the roots, and add water until the water can flow out from the bottom of the pot.

2. Too much fertilizer: any plant needs nutrition To support, but nutrients must also be controlled in a certain degree. When the amount applied is too much, which far exceeds the demand, and some is piled on the roots underneath, it will cause the root system to burn out. After it appears, you can dilute the concentration by adding water.

3. Insect damage: It has overall leaf curling, or it may be affected by insect damage. Aphids or leaf rollers spread wantonly, and leaf curling is inevitable. Opening more windows for ventilation can effectively avoid this situation. In the early stages, it can also be extinguished manually.
