how long will a cut christmas tree last outside

A cut Christmas tree can last up to a few weeks outside, depending on the weather and how it is cared for. You should keep it watered regularly and protect it from the elements. If you have a porch or covered area, you can keep it there, but if not, you should bring it inside every night. You can also try spraying it with an anti-desiccant spray to help it last longer.
