Why does watercress rot?

The root rot of watercress may be caused by improper temperature, excessive watering, improper fertilization or soil deterioration, so corresponding measures should be taken according to different situations. When the temperature is not suitable, adjust the temperature; Stop watering when watering too much; Improper fertilization requires diluting fertilizer with water; When the soil deteriorates, it is necessary to change the soil for farming.

The reason of root rot of watercress green 1 is that the temperature is not suitable.

People often plant watercress as a family pot, so why does watercress rot when it is planted? Root rot of watercress may be caused by improper temperature. When the temperature is too high and the roots of plants rot, we should do a good job of cooling down; When the temperature is too low and the roots of plants rot, measures should be taken to prevent cold and keep warm in time.

2, watering too much

The rotten roots of watercress green may also be caused by excessive watering and soil water accumulation. At this time, it is necessary to stop watering and drain the excess water in the soil in time. Watercress green is a water-loving plant, which can be watered according to the change of soil or season in the later stage of planting, and generally can keep the soil moist and not dry.

3. Improper fertilization

The requirements of watercress green on fertilizer are very strict, and too high fertilizer concentration will also lead to root rot, so it is necessary to properly water the soil to dilute the fertilizer. When the cultivated watercress turns green in the later stage, the plant can be applied with a small amount of fertilizer frequently or thinly, and the fertilizer can be diluted with water before each fertilization.

4. Soil degradation

If the soil is not changed for a long time, the poor air permeability of the soil will also lead to root rot of watercress, so it is necessary to change the soil in time for reproduction. Bean green likes to grow in loose, fertile and breathable soil, and the replaced soil can be mixed with humus soil, garden soil, river sand and perlite in proportion.
