    i have 2 tress that i want to dress up in my backyard with a raised mulch bed, i have heard conflicting opinons about putting mulch around trees, but i see it done all the time, is it ok to mulch around trees that are around 30 years old or older,i want to build up a bed around the tree made of stone about 12-24 inches heigh then fill with topsoil and then about 4 inches of cedar mulch on top of that

    You need to leave the root crown exposed. Make a secon ring around each tree, or taper the soil & mulch down to existing level. Otherwist the bark may rot, insects may get it, etc., & cause problems.

    What "he" said. A lot of people fill in around the tree too deep then the trees suffers. There are a lot of feeder roots in the first foot or so of soil that feed the tree. They will be suffocated if covered over. Taper your soil/mulch and you should be fine. A small layer of mulch 2-3" should be ok around the tree.

    You could stack an inner circle of stone around the tree but there is no way to build up around a tree trunk - if you add more than one inch per year it will not survive and it sounds like a pretty big tree .

    You can do this but do not fill with topsoil. You certainly can use mulch because it allows air into the soil but to add soil over any old tree's root area is talking a good chance on killing it.

    so sheshovel would it be ok for just adding mulch around the tree in a raised bed about 18 inches tall. this tree is about 50-60 ft tall and is the perfect shade tree and i dont want to hurt it

    I advise against it, 3" of 4" would be the thickest I would go.
