What to do if petunia root rots

1. Treatment methods

First, take it out of the potting soil, clean the soil, wash it with water, then use scissors to cut off the rotten roots until healthy roots are exposed, then disinfect the roots, prepare new soil and flower pots, and wait for it to dry before replanting it.

2. Prevention Methods

1. Scientific watering

Reason: Do not overwater the petunia. Once the soil is too moist or there is water accumulation, it will be detrimental to the growth of the roots and can easily lead to root rot. Its root regeneration ability is very poor, and it is generally difficult to save the roots after rot.

Solution: The amount of watering must be controlled. Water it thoroughly at one time. Wait until the soil is dry before watering again. Do not water too much, especially in summer, and reduce watering. In addition, the soil must have good drainage so that excess water can be discharged, and it will grow more healthily.

2. Proper rain protection

Reason: Petunia is most afraid of the rainy season. If it is still grown outdoors during the rainy season or is not sheltered from the rain, its roots will definitely rot, and in severe cases, the plant may die.

Solution: During the rainy season, you should shelter it from the rain in time and place it indoors or in a place where it will not be exposed to the rain. If you cannot shelter it from the rain in time, take appropriate drainage measures in time and do not let the water in the pot soil remain for a long time.
