This product extends the life of cut Christmas Trees along with Holiday Greenery Items & Wreaths. Spraying these will lock in moisture, the lack of which causes them to turn brown and drop their needles. Once the evergreens have been cut, they no longer are actively absorbing water. Wilt Stop slows evaporation to allow needles to remain on the tree and stay green. Fresh Evergreens can go from looking good for weeks to looking fresh for months.
