| | Mulching Landscape Plants, HYG-1083-96 |
 | | A mulch, by definition, is a layer of bark, sphagnum peat moss, muck peat, compost, pine needles, gravel, plastic, or any similar material uniformly spread on the surface of the soil under plants. |
 | | Mulching too early can delay drying of soil and subsequent root growth which is dependent upon sufficient aeration (oxygen content in soil) and reasonably warm temperature in the root zone. |
 | | Extra heavy mulch layers in autumn are often a haven for rodents to nest, which may lead to girdling (destruction of the food conducting vessel in the stem) of selected plants when wildlife food sources are covered with snow. |
