Fresh cut Fraser & Balsam Christmas Trees

We unwrap and stand all our trees for you to be able to inspect and choose the perfect tree for your home this holiday season.

We carry 6 feet to 14 feet Christmas Trees.

With the shortage of Fraser Fir trees over the last few years we have been fortunate and happy to be able to continue to offer Fraser Fir trees to our customers.

Did you know that ALL pre cut trees are cut in October? Cutting trees just after a few frost helps to put the tree in dormant mode while still leaving all the moisture and nutrients in its needles, helping to keep the tree last longer once recut and put in a stand of water. The later in the season you cut a tree the less nutrients left in it needles as the tree will store this in its roots for the winter season.


Nothing is more important then the health and safety of our customers and employees,
