Preserve your Christmas tree for up to 5 weeks by using these tips:
- If your tree was cut more than 4 hours ago, saw a 1” straight cut off the trunk and immediately place in water.
- Place tree in a stand that can hold at least 1 gallon of water. Water the new tree as often as necessary while it continues to soak up water, while never allowing the base to dry out. Plain water is best for keeping your tree fresh.
- Check for worn Christmas tree lights and electrical cords and always unplug the tree at night. Use UL approved electrical decorations and cords. Using miniature lights will produce less heat and reduce the drying effect on the tree or any chance of a fire.
