What is the cause of rose root rot?

1. The soil in the pot is not breathable

Reason: If the soil is not breathable, it will cause the potting soil to be damp and stuffy, which will easily breed bacteria and easily cause water accumulation, leading to root rot.

Solution: Replace it with soil with good air permeability.

2. Excessive watering

Reason: Roses are afraid of moisture, so if you water them too much, water will easily accumulate, which will cause root rot.

Solution: Control the amount of watering. Wait until the soil is completely dry before watering. Do not water too much. Just keep the soil surface moist but without water accumulation.

3. Large amount of fertilizer

Reason: Roses like fertilizer, but if too much fertilizer is applied, fertilizer damage will occur, and its roots will be burned and then rot.

Solution: Be sure to reduce the amount of fertilizer and the frequency of fertilization should also be appropriately reduced. Fertilize once before bud formation and after the flowers fade. Try not to fertilize at other times.

4. Pests and diseases

Reason: Bacteria will multiply in large numbers in a humid environment. The increase in bacteria will lead to a series of diseases and pests. These diseases and pests will harm the roots of roses and cause root rot.

Solution: If you find pests and diseases, you should remove them in time and spray them with pesticides to prevent them. Apply phosphorus and potassium fertilizers appropriately to improve the rose's disease resistance. The rotten roots should be cut off and disinfected to avoid secondary infection.
