Mistake 9: Using Too Much Pesticide
"My first year gardening I found a spot that I wanted to use for flowers. Problem? Grass. Solution? Grass killer, which unfortunately made the area free of grass and useless for growing anything else. Whoops."
Chemical herbicides poison the soil and can remain in the dirt for years, says Soler. Instead, get rid of grass and weeds by pouring an earth-friendly mix of equal parts hot water and vinegar over the selected area once a day for a few days until the offending plants turn brown. The vinegar will kill the leaves and most of the plants’ roots, making it easy to pull up the grass.
