Lurrrrv water cress, but hate paying supermarket prices for it, and I've always been intrigued by the idea of being able to grow it without the need for large volumes of water (running or otherwise.)

There's all sorts of growing advice ont 'tinterweb, some of it a bit conflicting - the best plan I've come up with so far is rooting some supermarket-bought stuff in water (box ticked - already showing signs of roots after 2 days) and then planting in a good-sized pot of compost standing in a bowl of water which is changed at least once a week.

The location apparently needs to be somewhere not too sunny or hot - I'm thinking underneath the staging in my greenhouse until it gets too warm, and then in a shady spot in the garden which gets little or no direct sun.

Feeding - some liquid fertiliser about once a week or so (poured into the pot rather than the bowl.)

Has anyone had any success with growing water cress, and if so does my plan appear to be anything like on the right lines?

I'd just grow landcress, unless you're set on an experiment. It tastes just as good.

On the watercress front, it grows on my local beach here where a water flow comes out of the fields, in full sun..

I think it was on the gardeners question time and one of the panel grew it in a polystryne box floating in a water butt

Water  cress is very easy to grow and does not need lots of running water. I grew it in a seed tray last year and dumped the neglected dried remains on the garden when I had finished with it. It has survived the winter and is now in flower! I admit it doesn't look nice enough to eat, but I hope to harvest the seeds shortly and sow them in the greenhouse.

I've thought about it before, but I am already harvesting very peppery land cress put in at the back end of last year, so will stick with that.

Good luck though.
