QuestionWhat kind of mulch should be used for a mature maple?
AnswerAny of the organic mulch is ok. I would use pine straw. Use not more than 3 inches deep and not piled up on the tree trunk. It is better to make a donut shape and use a little near the trunk. Mulch out about three feet around the tree. Do not use rock or such mulch this will compress the soil and also heat the roots near the trunk.
