When I planted my wife's tangerine tree, I did some checking and read that they like to have all competition removed from about 18-24" away from the trunk of the tree, or at the very least, to the to drip line. So I removed about 30" of grass from around the tree and bordered/edged it to help prevent the grass from creeping back in.
Then my wife came home three weeks ago and said, "I have something for you!" She opened her trunk and there was a box full of about 2 dozen aloe vera plants that someone had put out on their curb. I had/have no clue what I'm going to do with all those aloes. One thought I had was to put some of them on the inside edge of the tangerine's border. It is my understanding that aloe are pretty low maintenance and don't need a lot to grow, so I'm assuming that they won't steal too many nutrients from the tangerine tree, especially if they are not allowed to get any closer than 18" from the trunk. Is this a pretty fair assumption or would it be best to just leave that area clear and free?
BTW, the drip line is currently only about 12" from trunk.
