Christmas tree water

What common household items can I add to water so that my Christmas tree lasts longer?

nitrogen, phosphorus, and potassium—the major elements necessary for plant growth—and various trace, or minor, elements such as sulfur, magnesium, and calcium.

A cup of sugar added to a gallon of warm water. You don’t need anything else.

does this work for flowers also. sometimes when i buy my wife a bequay(sp) of flowers it comes with a little packet of power. is this packed just suger? can i use it for my morning coffie?:confused:

And no, it isn’t just sugar, at least not the ones I’ve seen. They tend to be minerals as mentioned above, possibly with a bit of sugar mixed in for volume.

The tree is already dead, I don’t see how it would benefit from any minerals. Just give it plenty of water to keep it from drying out.

The place where we get our tree recommends you mix up your own preservative with 1/2 cup Karo syrup, 1 teaspoon of chlorine bleach and 1 quart of warm water. Top off the stand daily with more mixture.
