Dwarf apple lean -- correction possible?
We have a dwarf Mutsu apple (great flavor) which developed a severe
"lean" after a fall rain. The tree was heavily weighted on one side with a lot of fruit. After more rain the lowest branch is nearly touching the ground. Has anyone had any success in righting such a tree, possibly by applying tension over months of time? My wife says just rip it out... and I have to say that once the soil has been displaced it's easy to imagine the same problem reoccurring even if we manage to straighten it up. Tales of success or failure welcome! -frank -- |

I would think it could be pulled back up to a better position. Maybe put
good tension on it and soak the soil with a hose and see what happens. I'm not sure how big this tree is but if it's a dwarf, it's not huge. I'm wondering if the trunk is still flexible? Usually by the time the tree produces very much fruit, the wood is pretty hard. If you do manage to improve it by either moving the roots in the soil or by flexing the trunk, you will want to stake it to hold it in that position for at least 2 years. Apple trees don't need to have a nice straight trunk. Don't overlook the possibility of creative pruning in the spring to force growth in the direction you want.

Hi Frank,
You do not say how old the tree is, or what size it is (trunk diameter). Your mistake was possibly not thinning the fruit to keep the weight off the branches, not propping up the weighted branches when the fruit got big, and not staking the tree earlier. I think your idea of gradually applying a righting force to the tree is the best approach. I assume this is a fairly mature tree, so digging it up and replanting would be quite a chore, and may disturb the roots too much. Depending on the rootstock you have the Mutsu on, the root structure of dwarf trees can be shallow, so staking them is not out of the question. You can also do some selective pruning to encourage more growth on the side opposite the lean, to balance the tree more. If this is a healthy and productive tree, I would not dig it out, as that would be a last resort. My dwarf trees have never leaned over as far as yours, because of the supports and stakes I use, but some of them have developed a lean. I have driven in deep stakes and applied gradual pressures and in some cases it straightens them, and in others it just keeps them from leaning more. If your soil is very loose, you may want to be more careful in future selection of dwarf trees as regards the root stock they are on. Sherwin D.

I go along with Steve, as you can see in my reply. However, I would not try
to necessarily straighten it out in one operation. I would apply righting force keeping an eye on the roots on the leaning side. If they look like they are coming out of the ground, or you hear some breaking, I would stop and wait several months before another attempt. I forgot about the wetting of the roots, and that is probably a good move to help release the pressure on the roots in the leaning side. If you have any roots exposed to the air, I would cover them with soil so they don't dry out. Sherwin D. Steve wrote: I would think it could be pulled back up to a better position.
