to elimate moss in lawn
Can I sprinkle wood ashes on moss at the base of the Italian prune tree. If I use commercial moss killer, will it harm the Italian prune tree?
Clackamas County Oregon
Moss control applied according to the label won't hurt the tree. Ash can be used, but be careful and don't pile it up. Here is an article with instructions for ash use from OSU Extension: "Wood ashes can benefit gardens and lawns": http://extension.oregonstate.edu/gardening/node/1022
