Hi Gang,
I am new to growing veg, but I have a knowledge of chemistry.
So when I built a greenhouse over weedy grassland, I covered it with wood chippings and gravel and then gave several doses of strong sodium chlorate, which I "Knew" would kill all plant life and deter animal life.
All was well until two weeks ago, I saw a clump of greenery popping up.
I gave it two more doses of extra strong chlorate at 2 day intervals.
And you can guess .......... The shoots are thriving! They look like spring bulbs - perhaps crocusses.
I don't know whether to go for some concentrated nitric acid or tell them they derserve to live on and give them pride of place in the middle of the greenhouse floor.
What do you think?
