We love the tradition of selecting a real Christmas tree, whether browsing the sidewalks of New York or visiting lots here in Los Angeles. We also consider “cut-your-own” tree farms, but in the LA area the best choices are usually imported varieties such as Noble and Fraser firs. Cypress and pine species rarely meet our expectations—the scent and overall appearance just aren’t what we’re after.
One of the main challenges with a real tree is keeping it hydrated. Indoor heating and dry air draw moisture out of the trunk and needles, causing needles to brown and drop more quickly.
Instead of simply topping the stand with plain water, we recommend a simple preservative mixture that helps the tree absorb water more readily and discourages microbial growth in the reservoir. The following solution uses light corn syrup and a small amount of household bleach. The corn syrup supplies an easy-to-absorb sugar source for the tree, while the bleach keeps the water free of mold, mildew, and other fungi. The mixture slightly acidifies the water, which can improve uptake compared with alkaline water.
If you don’t have light corn syrup, a small amount of granulated sugar can be used as a substitute.
- 1 quart warm water
- 1/2 cup light corn syrup (or substitute 1/2 cup dissolved sugar)
- 1 teaspoon household bleach
Before placing the tree in the stand, make a fresh cut across the base of the trunk—about an inch—from the original cut. This opens the sapwood and improves water uptake. Place the tree in the stand immediately and fill the reservoir with the preservative solution. Check the water level daily and keep the base submerged; a tree can absorb a surprising amount of water, especially in the first few days.
Additional tips to prolong freshness:
- Keep the tree away from direct heat sources such as radiators, fireplaces, and heating vents. Lower room temperatures slow moisture loss.
- Use a sturdy stand with adequate reservoir capacity so you don’t have to refill constantly.
- If needles start to brown rapidly, check that the trunk base is still submerged and that no debris is blocking the stand’s water intake.
- Consider using LED lights, which produce less heat than incandescent bulbs and reduce drying of branches and needles.
With these steps—fresh cut, preservative solution, daily water checks, and careful placement—you can extend the life, scent, and beauty of a real Christmas tree throughout the holiday season.
