• If you are planning a new landscape and aren't sure which trees or shrubs to plant, a tree service can help you determine which varieties to plant in your climate, what kind of maintenance they'll need, and so on.
• If you need someone to analyze the condition of trees or shrubs, a tree specialist can recommend treatments to keep them healthy and thriving.
• If a tree is damaged in a storm, a tree specialist can give an estimated value of the tree so you can claim a loss with the IRS.
• If you have damaged branches or just need trees or shrubs to be pruned, a specialist has all the equipment and can safely remove branches or simply prune an unruly shrub. Also, if you have a dead tree, they can remove it for you.
