Aside from removing dead or diseased branches, you should prune your trees somewhere between every one and three years. Some people—particularly commercial farmers—prune their apple trees yearly to produce higher yields. This is the best way to promote tree health. That said, the average homeowner can get away with hard-pruning their mature apple tree every other year or every three years. 

A tree growing close to a house can pose several risks, but removal isn't always the only or best solution. Potential problems include roots growing into the foundation and causing structural cracks, branches damaging the roof or promoting moss growth, and debris clogging gutters, which can lead to water damage. Trees can also provide access for pests and encourage mold. However, a small, healthy tree may not be a problem, and for larger, established trees, strategic trimming can be a cheaper and more beneficial alternative to removal. It is generally recommended to take action for trees within 10 to 20 feet of your home, especially if they are unhealthy or encroaching. Your best bet is to consult a professional arborist who can assess the specific situation and provide expert advice.

Since each tree is different, it’s impossible to say how long a dead tree can remain on your property. While it could be days, months, or even years, it’s highly likely that, at some point, the tree will fall. In the meantime, dying or dead trees can become a haven for pests, so it’s best to have them removed sooner rather than later.

No. Topping a tree refers to severely cutting down all its major branches and tree in a straight line. It was once recommended for streetside deciduous trees but has fallen out of practice. Topping leads to many problems, removing so much of the tree that many trees struggle to survive and become much more vulnerable to insects and diseases. Also, it doesn’t really help tree growth as once assumed and often leads to an ugly appearance of many sprouting stems in competition to become new main branches.
