Generally, you’ll want to avoid pruning more than 25% of the tree’s canopy at one time. While pruning your tree is important, it’s possible to do it too often or to go too far. Again, this is why hiring a tree trimming pro to do the work is wise. However, if you do decide to DIY, going slow and trimming gradually is the name of the game.

A general rule is that trees need 10 gallons of water for each inch of the tree’s diameter. For large trees, that can amount to approximately 160 gallons of water or more. Watering big trees to this extent can take quite a bit of time using a hose. For this reason, you may consider installing a soaker hose or sprinkler system to make the job easier.  

If you’re taking down a tree that you don’t suspect is affected by disease or pests and it’s nowhere near your home or other structures, then calling in a tree company should work fine. However, anything more involved means an arborist is a better option. These pros have years of experience with tree removal and can safely take down trees located next to structures, and they have the tools, sanitization equipment, and experience to remove sick or dying trees without infecting nearby trees. 

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.
