Identify my watercress

This cress is an aquatic plant of the cabbage family, moderately resistant to cold, which prefers rich and neutral or alkaline mediums, in partial shade. It forms drooping, slightly branched stems. The leaves are broad, oval, opposite.

Reap my watercress

Watercress can be harvested most of the year except in March and April - just before flowering. Be careful - do not harvest watercress grown near a sheep farm.

Sow my watercress

Sow in open soil from May to July, in semi-shade and in very moist, neutral or alkaline soil.

Plant my watercress

Plant preferably between March and July, in alkaline or neutral soil, rich in humus. Inopen soil, it is necessary to install a perforated plastic in a pit of twenty centimeters deep filled with potting soil and compost in equal quantities. Water copiously just after planting if necessary. In pots, plant in a pot with a volume matching your plant, otherwise if it is too small you will have to water all the time.

Water my watercress

Water regularly in the first weeks. Try to avoid watering on sunny afternoons to minimize the amount of moisture lost to evaporation. If your plant is in a pot, check the top soil in the pot either by looking at it or touching it with your finger. In any case, if it hasn’t rained in a month, water !
