A few weeks back I wrote about how I put lots and lots of mulch between the rows in my garden. A reader who is a landscape architect cautioned that, around trees, more mulch is not better:
"Unfortunately, when people put 3-4 inches of mulch around trees, they tend to think more is better and cover up both the ground and the trunk. This keeps the trunk moist and causes the tree to die. We, in the landscape business, call these piles of mulch around trees "mulch volcanoes" and urge you to think about putting less mulch down instead. While the mulch does eventually provide nutrients for the tree, putting 3-4 inches down tends to make the mulch harden rather than break down."
Well said, and thank you.
