Nothing spruces up a yard quicker than new mulch, but there are practical reasons to use mulch around your plants. Mulch keeps soil temperatures even and prevents water loss. Proper mulching discourages weeds and protects plant roots. Trees with shallow roots especially benefit when their roots are covered and protected from mower damage.
I’ve been asked. “How deep should I mulch around my trees?” Generally, mulch should be applied in an even layer about 2 to 4 inches deep. Never apply mulch against a tree’s bark, as it can encourage insect and disease problems. Piling mulch up around a tree in a volcano shape can create a pathway for harmful rodents. Keep mulch level and away from the tree trunk.
Have you considered using mulch in your garden? Compared to bare ground, mulch moderates soil temperature, retains moisture, and can keep the weeds down. Inexpensive, organic choices include: leaves, straw, newspaper, and compost. Let the soil warm up before spreading the mulch, keeping it no deeper than 3-4 inches. Grass clippings can be used if they are pesticide-free. Just keep them under 2 inches at any given time. Now is a good time to mulch your garden.
Speaking of grass. If your ornamental grass is starting to take on a doughnut shape with no growth in the middle, it’s trying to tell you something. It needs to be divided. Just dig up the clump, remove the dead center, divide the actively growing outer edge into smaller pieces, and replant. Spring is the best time to divide your ornamental grasses.
Short on garden space? You can grow many types of herbs in raised beds, the smallest garden plot, or in containers. Herb plants are happiest in well-drained soil with plenty of sunshine. Plant seeds according to package directions and thin them to the appropriate distance. Be cautious with mint and keep it contained. It is hardy and easy to grow but will take over if given the chance.
