Trees take decades to reach their full growth and maximum height, which can be too long of a period for some people. But don’t get disappointed because you can still buy a tree that can reach its full growth in years.
If you are planning to plant trees on your property, make sure you do thorough research into the size and width they will grow to. You don’t want to block out lots of light for your neighbours or plant anything too big to you house – root can cause structural damage to a property.
Why plant a Native Tree?
We would encourage you to plant only UK native trees to help your local ecosystem. Native trees will provide a habitat for insects and birds to shelter and get food from.
Trees will give you a degree of privacy to your property, especially if you plant evergreens.
