It depends. Smaller, younger trees take longer to mature, but they're more resilient, their roots don't get as damaged during transplanting, and they recover faster. Plus, they're much more affordable to plant, and it's possible to DIY the planting. 

On the other hand, mature trees produce fruit faster and provide more shade and privacy immediately. Ideally, a small or medium tree is the better choice if you can wait a few years for it to mature. But if you need immediate maturity, a larger tree is the only option.

It’s not always easy to tell when a tree is dying, although signs like dropping branches and brittle bark can sometimes offer clues. It can also be difficult to know whether a tree is dead or dormant, especially if it’s a deciduous tree. You’ll want to wait until a growth season to get a good idea of a tree’s health. When in doubt, contact an arborist for a consultation.

Since summer is a busy time for tree companies, the cheapest time of year to remove a tree is during the winter. February and March are typically the prime time to hire a tree removal pro, and some homeowners living in colder climates can save around 20% off services. It depends on location and the company, but you can always shop around for the best deal.

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.
