A great way to keep your cut Christmas tree and greens fresh is to spray them with "Wilt Pruf". This spray is a light, waxy protective coating that prevents them from drying out. It is applied directly onto the needles. It’s best to do this before bringing your tree inside. Once the tree is inside and set in the stand, make sure to give it a good drink of water right away. You should also add tree preservative to the water or a half can of sprite or mountain dew. If the tree is placed near a heat vent, the vent should be partially or completely closed. Continue to water as-needed.
