Many American families display a live Christmas tree in their homes during the month of December, and they all face the same challenges when it comes to keeping the tree hydrated. A live tree, just like any other plant, requires a certain amount of water to stay fresh. Without adequate watering, a Christmas tree becomes more than just an eyesore; it becomes a safety hazard. The primary cause of Christmas tree fires in residential homes is that trees haven't been watered properly, and thus have dried out, becoming nothing more than kindling for the flames.Watering a live Christmas tree is a job often relegated to young children, because it requires crawling under the branches to reach the water reservoir in the tree stand. This is an unpleasant job, leaving you sticky with pine sap and scratched from conifer needles. The main problem with having a child complete this task is that they may be more likely to spill water on the floor. And if your family likes to add a little green food coloring to the water to keep the tree looking green, well then you've got a real recipe for disaster.What many families don't realize is that there is a simple device called an automatic Christmas tree watering system that can make the job easier. Christmas tree watering systems come in many styles, shapes, and price points, but they all perform the same basic function, and that is keeping the tree hydrated. If you're not quite sure whether it's worth it to spend the money on an automatic waterer, we've got a list of five reasons why it merits consideration.1. You won't forget to water the tree.The key part of an automatic watering system is that it's automatic, meaning you don't have to remember to do the job all the time. In most cases, you just fill the waterer and it will keep your tree hydrated for a week or so at a time.2. It makes the job easier.As we've already discussed, watering the tree is an unpleasant job. An automatic watering system can usually be placed to the side of the tree, so you don't have to crawl around or underneath the branches anymore. No more getting poked, pricked, and scratched!3. You can go on vacation without worrying about the tree.Some families actually don't display a tree at all, or else they've switched over to artificial trees, simply because the month of December includes travel plans that would prevent them from watering a live tree. If you buy the right type of automatic watering system, you can hook up multiple units to extend the tree's water supply for several weeks at a time.4. A wet tree is a safe tree.When a live conifer becomes dried out, you have a far bigger problem than a brown tree with a lot of dropped needles. You have a fire hazard. Testing conducted by the NIST (National Institute of Standards and Technology) has shown that properly hydrated trees are almost impossible to ignite and burn, even when exposed to an open flame.5. It's a reusable product that will last for years.Almost all Christmas tree watering systems are designed to be reusable, so if you buy a good quality one, you'll likely be using it for years to come.
