Hey there, fellow gardeners! I’ve been growing lemon cypress trees for years and one of the most common questions I get is about their winter survival. Let me share everything you need to know about keeping these beautiful yellow-green beauties alive during the cold months.
The Quick Answer
Lemon cypress can survive winter, but it depends entirely on where you live These trees are hardy in USDA zones 7-10, meaning they can handle temperatures down to about 10°F (-12°C) If you live in colder regions, you’ll need to take special precautions or grow them in containers that can be moved indoors.

Light
Lemon cypress trees require a good amount of light. Outdoors, a lemon cypress tree should be planted in full sun to partial shade. Indoors, the tree needs 5 to 6 hours of indirect sunlight or morning sun; dont put it in a wast-facing window, as the bright light can harm the foliage.
Water
As an outdoor shrub or tree, once established, the lemon cypress needs little supplemental watering. Allow the plant to establish itself by watering it once a week during the first season.
If kept as a houseplant, give it a thorough deep watering weekly, ensuring the soil is never too dry.
