The benefit of mulching is obvious in this photo. Two rows of raised beds created at the same time, the one on the right utilized deep leaf mulch, the one on the left used no mulch. The left gardens are full of crab grass that’s grown in over the winter and spring. The right side garden has hardly any grass and weeds plus the moisture in the soil is much higher. The mulch will slowly break down, feeding and attracting worms who in turn make vermicast to feed the plants. We can’t say enough good things about mulching, what’s not to like?
