Trees are great. They provide shade, protection, homes for wildlife especially birds.
But there are also downfalls depending on your view.
Tall trees close to buildings can be a detriment during storms. Tree removal may also be expensive if one needs to be removed.
But the biggest complaint is the leaves. A lot of trees means a lot of leaves, or in some cases pine needles.
Before deciding to have a lot of trees, remember there are also downfalls. If you don't mind the extra work, you will be rewarded.
