What is the cause of geranium root rot? How to remedy geranium root rot

Geraniums, also known as hydrangeas, are known for their gorgeous flowers and long flowering period. Many people grow one or two pots of them in their gardens, but many people find that their roots rot after growing them for a while. So what is the reason for geranium root rot? Let's take a look at it together.

What is the cause of geranium root rot?

1. The soil has poor air permeability, so accumulated water is not easy to drain out. If there is accumulated water in the potting soil and a stuffy environment, it will easily lead to root rot.

2. Many flower lovers are careless when repotting, and often injure the roots of geraniums. Once wounds appear, coupled with bacterial growth, it will lead to root rot.

3. Excessive watering can easily cause water accumulation. If the accumulated water cannot be drained, the roots will rot.

4. If pests and diseases appear, such as nematodes, it can easily lead to root rot.

How to remedy geranium root rot

Replace the soil

When we are caring for geraniums, we need to change the soil regularly. Because geraniums absorb nutrients from the soil for a long time, it can easily cause the soil to become compacted, which will make the soil air permeability and drainage worse. The roots of geraniums cannot be exposed to enough air and will rot. Therefore, we need to change the soil for geraniums every one to two years.

Proper watering

Geraniums like a dry growing environment and are very afraid of water. If we water too much and cause water accumulation, the roots of the geraniums will rot. At this time, we need to drain the accumulated water and increase ventilation. If the root rot is very serious, then we need to check the roots of the geraniums, trim off the rotten roots, disinfect them, and then re-pot them.

Reasonable fertilization

Geraniums do not like heavy fertilizers, so when we care for geraniums, we need to apply light fertilizers frequently. If the concentration of fertilizer is too high, the roots of the geraniums will be burned and will easily rot. If the root rot is caused by excessive fertilizer concentration, then we need to immediately rinse the soil with plenty of water. If the situation is serious, we need to trim the roots and repot.

How to determine if geranium blueberry has root rot

1. Both old and new leaves begin to turn yellow. When you find that the leaves of geraniums are yellowing, if only the old leaves are slightly yellowing, it means that they are lacking water. If both the old and new leaves are yellowing, it means that the roots are rotten.

2. The whole plant turns yellow. Although we haven't seen yellow leaves yet, the edges of the leaves are starting to turn yellow, and the leaves are lifeless and very soft, which is likely to be root rot.
