After the recent weed infestation I did a lot of manual weeding but also wanted to kill off any seeds sitting on the surface. Since High-Water is completely organic I don’t use any chemicals but instead use black plastic to kill the weeds. The black plastic has two benefits. It not only blocks out the sunlight completely, but it bakes anything underneath. It’s surprising how hot it gets under that plastic. You can see the plastic in the middle of the photo below.
These are broccolini seeds I harvested from last years crop.
