Question: How should I mulch around trees?
Answer: I've seen people build a stone-wall raised bed around a big tree on their lawn, then fill the raised bed with mulch. Avoid mulching around trees like this! You may build stone walls or other structures around your trees to set them off, but do not mound up dirt or mulch around the trunks of trees. Doing so may cause harm to your trees. If you are mulching around a tree, start tapering the height of the mulch down when you get to within about 1' of the trunk, leaving the base of the tree free of mulch. It would even be better to have to weed this 1' than to risk damage to your tree.
