“By this point, there will have been a good frost, allowing for better needle retention,” she adds. “As long as your tree has enough water every day, it will last all Christmas season.” That said, if you can’t make it to a Christmas tree lot or don’t have access to a vehicle (we’re looking at you, city dwellers), you can shop online for live Christmas trees. “Measure the width of the door through which you’ll be bringing in the tree, and make sure your chosen tree fits through it easily,” advises David Murbach, manager of the gardens division at New York City’s Rockefeller Center.

Christmasy scent: Balsam firs smell like your favorite holiday candle and maintain their scent longer than most other Christmas trees.Strong branches: If you’re planning to adorn your tree with heavy ornaments, a noble fir’s flexible branches can support them—and endure repeated tugs from children and pets.Needle retention: The Fraser fir is the champ here (your vacuum will thank you).Soft needles: Families with little ones should consider a flexible-needled white pine, which won’t prick if someone gets too close.Good for allergy sufferers: If a fresh tree brings tears to your eyes, try a pollen-free Leyland cypress.

“Keep the tree away from any heaters, direct blows of heat (like a fireplace), and direct sunlight,” says Greene. “Christmas trees thrive in cold weather, so direct heat will reduce its lifespan.” “Trees don’t just burst into flames,” Greene says. “It’s the lights that can cause a fire. Make sure there is no breakage in the line, and you don’t short the circuit."  If you’re worried about your cat or dog not being able to stay away from the tree, get an artificial one (and light a fir-scented candle to keep your holiday spirit high).
