Growing watercress

Question ...

Do you have any information/hints on growing watercress? I plan to grow it in a polythene lined pallet (with 1inch lip around pallet). This will then be filled with a non peat-based compost, thoroughly soaked and then broadcast sown. This is being done under glass.

Answer ...

Watercress is really easy to grow from seed and does not need running water as in a river or stream to grow. What you intend to do sounds fine - but you don't need to grow the crop under glass unless you really want to. Watercress will grow happily outside as long as the soil is kept moist. Once established, regular picking is essential as it does have a tendency to flower quickly.
