Your local government is usually in charge of pruning trees on public property, and the power company is responsible for trees near power lines (even if they’re on your property). Whether or not they top these trees depends on their approach to pruning. You won’t be able to do much to control this, but you can contact them to find out more about their pruning process.

Generally, you should prune around 20% of an apple tree’s growth—and never more than 30%. This means that if you have a severely overgrown tree, it can take a few seasons to prune it back enough to produce the healthiest fruit. 

If you’re dealing with a newly planted or juvenile tree, hold off on pruning beyond the initial shaping. Wait at least a couple of seasons into fruit production since pruning can increase the number of water sprouts and unproductive foliage.

Yes, you can prune a palm tree with a chainsaw, but a chainsaw is overkill for a job like this. You risk damaging the tree if you make a bad cut. More commonly, you’ll need pruning shears or a serrated knife to trim a palm tree, or you can use a specialized pruning saw instead of a chainsaw.

There are several signs that may indicate a tree needs to be cut down. These include visible damage to the trunk or branches, a hollow trunk, extensive storm damage, or a significant lean to one side. Other warning signs are pest infestations or the tree growing too close to a house, power lines, or other structures. It is best to hire a professional arborist to inspect the tree, as they can determine if it can be saved or if removal is necessary.
