If you pass a beautiful tree down a country road and think it would make the perfect Christmas tree, but generally, you cannot cut trees just anywhere.
If you wish to cut down a tree on your own property, you generally do not need permission to do so (unless the tree is protected by a TPO). If you would like to cut your own Christmas tree but have none on your property, you can check your neared tree farm.
Some tree farms even offer events and supply decorations or accessories for your tree, such as tree stands.
The Forestry Commission lists the locations of tree farms in England.
The website Pick Your Own Christmas tree lists tree farms in Scotland and has lots of great tips.
Make sure these farms can help you cut your own Christmas tree in safety and have experienced staff, equipment and proper insurance.
