All part of the food cycle - same as adding horse/cow muck to the veg patch - all good stuff
I give mine a good rinse and have been eating it for 5+ yrs with no (known) ill effects
I just popped a bit in at the top of the waterfall and although there's not much in the summer, most of the year it grows quite well - sometimes too well.
I love a bit of dirt
I wouldn't eat it if the stream passes through grazed pasture - even if the cattle are off the land for some of the time. Not sure of the biology, but I wouldn't risk it.
Thank you.... totally forgot about this thread I started. I went to my local garden centre to buy a few packets of seeds and to my surprise they now stock watercress seeds so I'll be growning it safely on my veg patch.
A quick pic.... I do eat a lot of watercress so hope they are successful.
If you cut watercress does it re-grow from the roots?
Thank you Runnybeak.... I'm looking forward to seeing/tasting the outcome.... I make a lot of watercress soup winter or summer.
Flowerlover....This will be the first time that I have grown it.....
