Avocado base re-work ok?
I have three avocado trees. They were planted in August 2012 and are doing "ok" I would say. They started off with a lot of brown leaf tips/drops and didn't look very good but after some adjustment seem to be looking better.
I had them all covered with landscaping fabric and then bark and thought maybe I could do better so this is what I came up with. It's like a before-and-after, but with two different trees. I have only done one so far. Am I on the right track? Anything else to do? I have the one its first shot of fertilizer and hope it will stimulate some growth over the summer.
