Is Your Lawn Pickled?
Worried about thatch? If you're fertilizing PRFCTly, you don't have to be.
Thatch is a naturally occurring layer of decaying material that accumulates in soil. A ½" layer of thatch is healthy. It acts as insulation for soil and roots and a cushion for your kids' knees when they fall on the grass.
Thatch build-up is not caused by the presence of grass clippings. In fact, having organic material like grass clippings on your lawn feeds the same microbes that remove excess thatch from your soil.
Problems occur when soil is pickled by the salts and acids in chemical fertilizers and pesticides, preventing the natural composting process from taking place. Material builds up, resulting in a thick layer of thatch that attracts pests and creates conditions for fungus to spread.
Instead, prevent thatch build-up by fertilizing your lawn with natural fertilizers like compost tea and, of course, grass clippings.
