Sowing and planting watercress

Here are our tips for growing watercress, from sowing and harvesting to watering and pests to watch out for.

The watercress seedlings is carried out in waterlogged soil or kept very humid, and rich in humus (mixture composed of 50% potting soil or good garden soil, and 50% compost).

  • Bury the seeds a little (0.5-1cm).
  • Transplanting takes place when the seedlings have 4 or 5 leaves.
  • You can also plant, directly in place, young plants purchased in pots or mini-clods.

Since watercress is a plant that grows naturally in running, shallow water (river banks), it is necessary to provide, in the absence of a stream, a 30 cm deep culture tank to the maximum.

If the water is not constantly renewed by a pump system, it must be changed at least twice a week.

What watercress likes:

  • waterlogged soil, ideally running water
  • rich soil
  • transplanting, which strengthens the seedlings.

Watercress diseases

Watercress is not prone to disease and, apart from aphids, it is little affected by pests (the stems that emerge from the water are beyond the reach of slugs and snails).

Harvesting watercress

Harvests take place about 6 weeks after transplanting or planting. You simply cut the leaves and stems as needed.

In the fall, protect the crop from frost with a wintering veil to extend harvests.

Warning ! Never harvest wild watercress: it can harbor the liver fluke, a parasite that causes the dangerous liver disease in humans, distomatosis.
