what kind of mulch to use in my shrubs
Uses for Organic Mulches: 1  Bark mulches are best used around trees, shrubs and in garden beds where you wonât be doing a lot of digging, like front walkways and foundation plantings. 2  These woody mulches donât mix well into the soil and it can become a hassle to have to keep moving them aside to make way for new plants. You can use them as a coating of mulch or simply side dress plants with them during the growing season, to insulate and give a boost of slow released nutrients. 2  Grass Clippings are a mixed bag and are best suited to remote areas of your garden where you basically want to suppress weeds.
