I have about two year old avocado that doesn't seem to be doing that well. It grows new leaves from time to time but the older leaves tend to turn brown at the same rate. It's an indoor avocado that is grown from seed.
It is also grown quite tall since it's not getting that much sun. I have a grow light over it but it doesn't seem enough. I'm also aware that I may be a bit late with pruning if I had wanted a shorter bushier avocado. Now, my thinking is that I can still prune it, but I don't know how much is okei, since all of it's leaves are on top. Would it be okei to cut it in half? Would it start growing again from the stub?
