Generally speaking, you’ll want to avoid flush cuts, which are cuts made as extremely close to the trunk or main branch. These cuts can weaken your tree, lower its natural defense mechanisms, and even cause decay. You’ll also want to avoid tree topping, which is the total removal of the leader and upper main branches of a tree. 

Most pros will advise against either of these methods, which is why hiring a pro is often the best choice when it comes to tree trimming.

It takes anywhere from three to seven years for a stump to decompose on its own. This timeframe can depend on the kind of tree and your climate. The lower to the ground the stump is, the faster it rots. If you kill a tree stump with salt, boiling water, herbicide, light deprivation, or burning, the tree stump decomposes faster. 

For small trees, tree removal should take just a couple of hours to complete. Assume that a mid-sized tree will take between four and eight hours, depending on the extent of the equipment required and the health of the tree. Remember to add up to two hours for stump removal. Larger trees could take as long as one or two working days, about eight hours each.

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.
