19 sustainable Christmas tree choices
The most eco-friendly Christmas tree is one that lasts for years. Here’s how to choose, decorate, and care for a living tree
You can use the same tree in a container for four to seven years, depending on how fast it grows. If you intend to plant it outdoors eventually, choose a variety that thrives in your climate. And be sure that you have a sunny spot for it.
Look for landscape-grade trees (not sheared), in 5-, 7-, and 15-gallon cans.
To 70 feet tall. Sunset zones 1-9, 14-24.
Can hit 150" in height. Sunset zones A2, A3, 1-6, 14-17
A good container plant. Sunset zones 1-9, 14-24.
Picea pungens ‘Hoopsii’. ‘Glauca is the standard Colorado blue spruce, but ‘Hoopsii’ is even bluer. It its best in colder areas; a poor choice in Puget Sound region where lack of winter cold leads to severe aphid infestations.

Grows slowly to 40 to 60 feet tall. Mature trees develop flat tops. Zones A3, 2-10, 14-21.
Dwarf blue subalpine fir grows to just 3 to 4 feet tall in 10 years, ultimately reaching 6 to8 feet tall. Zones 1-9, 14-17.
Potentially a huge tree, to 80 feet or more. All zones.
A good garden tree if you have room. To 80 feet tall. Zones 2-12, 14-24.
- Plan ahead. Buy a variety that thrives in your zone. After the holidays, keep it in a container to reuse year after year, plant it in your garden, or donate it to a local park. If you plan to plant, make sure you have space to allow for the tree’s growth.
- Do not disturb. Leave the tree in its nursery container for at least the first Christmas. You don’t want to add transplant shock to the stress of an indoor stay.
- Limit its time inside. Display the tree indoors no longer than 10 days, keeping it away from heater vents, fireplaces, and drafts.
- Water regularly. The easiest method: Place ice cubes atop the soil. As they melt, they slowly release water, which is gradually absorbed by the roots.
- Take it outside. Most trees can live outdoors for several years in large containers. Water regularly, when the top 2 inches of soil are dry. When new growth starts in spring, feed with a granular, controlled-release fertilizer.
Go ahead, gild that little tree. But stick to ornaments in a single metallic finish for a polished outcome. Tuck in twigs spray-painted gold and doused with glitter for extra shimmer.
