Water cress does not have to be grown in running water according to BBC’s Gardeners’ Question Time last Sunday.
Watercress roots grow in the water, but the plant grows above the water. To harvest cut the leaves above the water leaving about 10cm of stem, which will regrow. Watercress is a cut and come again herb!
Two ways of growing water cress were described on the program:
- on the water surface in a water butt
- in a washing up bowl with holes in the bottom which is placed in a water bath. The water should be changed weekly as watercress does not like stagnant water
To Grow Watercress:
- Plant watercress seed on a paper towel that has been soaked in water in April
- Keep the paper towel moist
- Germination takes about 10 days
- Place the seedlings into their growing position when the danger of frost has passed
- They like full sun.
For a shortcut way to grow watercress:
- buy a bunch of watercress at the greengrocers
- place the bunch in a bucket of water
- put the bucket outside in full sun
- change the water daily
The dark green peppery flavoured leaves of Water Cress are rich in vitamins and minerals including vitamin C and iron. Watercress is quite easy to grow.
