What causes root rot in mint?

1. Overwatering

Cause: If you usually water too much, waterlogging is likely to occur, and once waterlogging occurs, root rot easily develops; its roots cannot breathe normally, which leads to root rot.

Solution: Reduce the amount of watering, and wait until the surface soil dries before watering, but never water too much. If you have watered too much, loosen the soil appropriately and place it in a ventilated spot.

2. Too much fertilizer

Cause: If you do not get the fertilizer amount right, frequent over-fertilizing will cause fertilizer burn, which in turn leads to root rot.

Solution: Reduce the amount of fertilizer. After root rot occurs, stop fertilizing, take it out of the potting soil, cut off the rotted roots, then disinfect them, and replant after disinfection.

3. Poorly aerated potting soil

Cause: If the potting soil is not breathable, then once waterlogging occurs, root rot develops very easily. Especially in the rainy season, if the potting soil is not breathable, it will not only cause root rot but, in severe cases, can also cause the whole plant to die.

Solution: Replace it with a breathable flower pot, and also change the soil to a loose, well-aerated soil, so that water can drain out more quickly when waterlogging occurs.
