How to prevent geranium root rot

There are many reasons for geranium root rot: excessive watering, resulting in water accumulation in the pot; a hot and stuffy environment, which prevents the roots from breathing well; pests and diseases, which eat the roots; and improper fertilization, which burns the roots. Any inappropriate behavior in maintenance will cause root rot. The point is not to analyze the cause, but to find ways to avoid it.

Choosing the right soil

The quality of the soil determines the root growth of geranium. Choose sandy loam that is rich in humus, well-drained and has good permeability. The roots grow robustly and are relatively resistant, and even if properly maintained, they will not rot easily.

Be careful when repotting

Geraniums need to be repotted or replaced with larger pots every autumn, which can cause extensive root damage. Therefore, when operating, keep the shovel away from the root system to avoid cutting the roots. You must know that every wound is fatal to the plant.

Watering Correctly

Proper watering is the key to preventing root rot. Don’t water too much at normal times. You can water a little more during the growing season in spring and autumn, but the soil in the pot should not be waterlogged. Watering should be strictly controlled during the high temperatures in summer. Try not to water unless the soil in the pot is very dry, especially at noon, as watering will harm the plant. In addition, during the rainy season in many places, the potting soil should not be exposed to rain or excessive moisture for a long time. You can collect rainwater for watering, but pay attention to the amount.

Pest and disease control

Nematodes are the main pest causing root rot in geraniums. When planting, it is best to use artificial media such as perlite and vermiculite, or disinfect the soil. And if diseased plants are found, they should be removed and burned in time.
