My backyard has five feet of land which is full of grass. Recently I used vinegar on the grass per your tips on your website. The problem is that I don't get enough sunlight in my backyard. Will the vinegar still kill the grass? How often do I need to spray the grass with vinegar?
Killing Grass With Vinegar
Certified GKH Gardening Expert
The acid in the vinegar is what kills the plant more than anything. If it is a tough plant, it may take several applications. I would apply it every few days until they are dead. If there are no plants in that area that you wish to save, I would recommend boiling water. Pouring this on the plants will kill them instantly.
