I think one will be enough, unless you think it may not survive. I had 9,000 at one time. It proved to be too much.
Peaches are a problem with the curl. I do not spray, so when it rains a lot after they leaf out, I am in trouble. Some of mine have gone back to the root stock. So, I am working with my pecans now. But, as Scripture says, I must work by the sweat of my brow. With the pecans, it is the gray squirrels that I have to contend with. For years I let them have most of them, but now, with the price of nuts having gone way past affording them, I am contending with Charlie. I can't bring myself to injure them, but I surely can discourage him. I gave him five trees and I want my other three. So, when he ventures into them, he knows I am coming with the hose. He doesn't like be squirted. So, I have to be on my toes because he knows just when to start picking and then the race is on. The problem is, he is happy taking a few nuts at a time. I have to wait until many are ready. So, I have to stand guard for a couple of weeks. Same with the deer. We have a thread on the deer. They are quite cute, but to me they are the enemy. Roses, photinia, tomatoes, and what ever else they want, they eat. Such is the life of a gardener. Money would solve the problem, I am sure. I could surround all with a protective barrier so that Charlie and his friends could not get to the nuts, fruits, and veggies. But, God is control, so I just keep my guard up.
