Over the last two weeks the weeds and grass have been coming back through the mulch around the Hazels. I knew I needed a thicker layer of mulch, but wanted to address the weeds with something first. Kitty found a recipe for weed killer consisting of a gallon of vinegar mixed with a cup of table salt and a tablespoon of liquid soap to help it cling to the weeds. So I sprayed the weeds today before adding more mulch and was amazed at how quickly it started to work. There was significant wilting just after thirty minutes. Here are some before and after photos demonstrating that.
It clearly worked faster on the broad leaf weeds and clover. It seemed to be working slower on the grass. I expect that I will have to continue to treat the mulched areas over the Summer, but I am pleased with how this concoction is working so far.
