Rock salt or Epsom salt can damage and kill tree roots over several weeks and can even assist in removing the tree's stump. However, you need to drill holes or cut into the stump and surface tree roots to inject them properly with the salt. Repeat the process every two weeks until the roots visibly rot away.

It may be possible, but transplanting a large, mature tree can be a tricky project, and some trees handle it better than others. If you have a tree you need to save and are considering transplanting it elsewhere, we highly suggest calling a tree removal service and arranging a consultation to see what they say (and how much a full transplant would cost).

If you’re wondering whether you can plant a tree where the stump was removed, know that the soil conditions won’t be ideal, so you should avoid it. The soil beneath the previous tree will likely be depleted of nutrients, plus there may be roots left behind that will seriously hinder the growth of a new tree. Also, if you use salt or other chemical solutions to kill the stump, these can linger in the soil for months or even years and prevent healthy growth. It’s best to choose a different spot that’s at least three feet away for a new tree, or wait at least a year and thoroughly amend the soil before you plant.

Generally, you’ll want to prune back the trunk by 1 to 2 feet each year to promote bushy growth. Doing so concentrates vegetative buds closer to the bottom of the tree, where you can easily harvest fruit. For side shoots that are a year old, leave at least six leaves. 

Never remove more than 30% of a tree’s foliage during pruning—even if your tree is really overgrown. Removing this much foliage at a time could kill your tree.
