Will I die if .....?
...if I grow water cress in my newly resurrected pond and eat it? I have ordered a solar fountain for it and it is newly washed and scrubbed. I already have nasturtium growing around it so I would prefer to put something edible to keep it looking nice. I have read that the water could contain some nasties. Here is a photo - it is not big and not filled yet.
A good hoeing is worth two waterings.
