The watercress approach to algae
Today I decided it was time to do something about the hideous algae in my pond.
In case that was not sufficiently disgusting for you, here is a close-up version:
At least two people have told me to chuck watercress in it, and one was my mum, so I went to Sainsbury’s and bought some. I was thinking of just throwing it in as it was, but I thought it would be tidier to put it in pots full of gravel, so that is what I did. And then I chucked the rest of the bag into the shallow pond, loose. The algae in the shallow pond is just as bad as the algae in the raised pond. People say that the watercress roots very quickly and easily. If it is invasive, it will be easy to empty out the shallow pond and start again. The raised pond would be harder to deal with.
