What to do if the roots of Rieger Begonia rot

1. Improper watering

Reason: When caring for it, watering is the most important step. If you water too much, water will easily accumulate in the pot, causing the roots to lack oxygen, which in turn affects their breathing. Over time, the roots will naturally begin to rot. However, you cannot go without watering for a long time, as this will prevent the roots from getting enough water and cause root rot.

Solution: When you find root rot, cut it off in time. If it is caused by overwatering, you need to replace part of the soil and reduce the amount of watering, especially in summer. You should wait until the leaves begin to wilt and the soil in the pot is dry before watering. Also water less in winter to prevent frost damage. If it is caused by too little watering, you need to increase the amount of watering and water it thoroughly at one time.

2. Improper fertilization

Reason: When fertilizing Begonia, if the concentration is too high and the amount of fertilizer is too large, it will cause fertilizer damage, which will then burn the roots, and the roots will begin to rot.

Solution: First, cut off the rotten roots and replace the soil in the pot. Then, when applying fertilizer again, dilute the fertilizer to prevent burning the roots. In addition, the number of fertilizations should be reduced appropriately. Usually, fertilization should be stopped in summer and winter. In spring and autumn, just apply a little more.

3. Improper temperature

Reason: Begonia is very afraid of cold. If the temperature is too low indoors or outdoors, it will cause frost damage, especially in winter. This will first damage the roots, and then the roots will begin to rot.

Solution: The appropriate temperature needs to be maintained all year round, especially in winter. It should be moved indoors in time and the indoor temperature should be kept at around 4 degrees. This will avoid frost damage and the roots will not rot.
