Lead serves as a stabilizer in some forms of PVC. The one serious study (PDF) we’ve seen on artificial Christmas trees, published in 2004 in the Journal of Environmental Health, found that the lead levels and risk of lead exposure were generally very low, and well below federal guidelines at the time; a few models were outliers, however, and one slightly exceeded the federal limits. Lead exposure occurred in two ways: direct contact with the branches—as may occur when people are setting the trees up and decorating them—and contact with PVC dust beneath the tree, the result of physical decomposition of the “pine needles,” a particular concern for crawling infants. Significantly, new trees (new in 2004, that is) generally showed much lower levels of lead than trees manufactured in the 1980s and 1990s. The authors concluded that while the proportion of trees made with lead-stabilized PVC had “decreased only modestly” in the 20 years preceding 2004, “the amount of lead stabilizer used has been reduced to a much larger extent,” suggesting a long-term trend toward low-lead or lead-free artificial trees.

Second, it needs a sizeable reservoir of water to keep the tree moist and “alive” (or at least prevent it from drying out and losing all its needles) for as long as possible. A dry tree is not only ugly and messy, it’s a fire hazard. Though this is rare, it does happen—according to the National Fire Protection Association, between 2009 and 2013, Christmas trees were the source of an average of 210 home fires each year, according to a National Fire Protection Association. So how much water is enough? The National Christmas Tree Association notes that, “Generally, a tree can use up to one quart of water per day for each inch of stem diameter.” That’s 1½ gallons each day for a 6-inch-diameter tree. Larger water capacity is always better, so you’re not constantly worried about watering the tree.
A big tree in your living room can make even a spacious home feel a lot smaller. At the same time, a small tree can get lost in a wide-open area. Fake Christmas trees come in a range of choices in height and fullness to work in any space. For a small home or apartment, a slim or potted tree works well, while a room with a cathedral ceiling calls for a tall, full tree. You also want to make sure your tree is big enough to hold all your treasured holiday decorations

A chronicle from Stasbourg, written in 1604 and widely seen as the first account of a Christmas tree in German-speaking lands, records that Protestant artisans brought fir trees into their homes in the holiday season and decorated them with "roses made of colored paper, apples, wafers, tinsel, sweetmeats, etc." ... The Christmas tree spread out in German society from the top down, so to speak. It moved from elite households to broader social strata, from urban to rural areas, from the Protestant north to the Catholic south, and from Prussia to other German states.
For even more convenience, purchase a pre-lit tree so all you have to do is add ornaments and garland and you’re ready to celebrate. To help save money on electric bills, try a Christmas tree with energy-saving LED lights and add a light timer to make sure your lights consistently turn off at the same hour each night. Even better, you can set up Remote Control Christmas Trees that let you change the color of the lights with just a click of a button.
