Whether in containers or with proper winter protection, growing citrus beyond the tropics is easier than you think!
In this guide, we’ll explore the best cold-tolerant citrus varieties and share essential tips to keep your trees happy and productive year-round.
Tips for Growing Citrus in Cold Climates
If you’re determined to grow citrus in a chilly environment, here are some essential tips to keep your trees healthy:
1. Choose the Right Variety
Opt for the most cold-hardy citrus trees, like Satsuma Mandarin, Meiwa Kumquat, or Ponkan Tangerine.
2. Use Containers for Mobility
Growing citrus in pots allows you to move them indoors or into a greenhouse when temperatures drop.
3. Provide Winter Protection
If growing outdoors, use frost cloths, mulch, and wind barriers to protect trees from freezing conditions.
4. Position for Maximum Sunlight
Citrus trees love the sun! Make sure they get at least 6-8 hours of direct sunlight daily, even in winter.
5. Maintain Proper Watering
Overwatering in cold weather can lead to root rot. Allow soil to dry slightly between waterings.
6. Use Cold-Resistant Rootstocks
If planting in the ground, look for trees grafted onto rootstocks known for increased cold tolerance.
7. Fertilize Appropriately
Citrus trees need regular feeding. Use a balanced citrus fertilizer and reduce feeding in winter when growth slows.
8. Consider a Greenhouse or Indoor Grow Setup
If you live in an area with harsh winters, investing in a greenhouse or indoor grow lights can keep your citrus thriving year-round.
Persian Lime Citrus
A seedless, juicy lime variety, Persian Lime is slightly more cold-hardy than Key Lime. It does best in a pot, where it can be moved indoors when frost threatens.
Satsuma Mandarin
One of the most cold-hardy citrus trees, Satsuma Mandarins can survive temperatures as low as 15°F (-9°C). These sweet, easy-to-peel mandarins are an excellent choice for outdoor planting in cooler climates.
Navel Orange
Navel Oranges are not the most cold-hardy, but they can be grown in large pots and moved indoors when temperatures drop. Their seedless, easy-to-peel fruit is a wintertime favorite.
Meyer Lemon
A hybrid between a lemon and a mandarin, Meyer Lemons are more cold-tolerant than other lemons. They can survive short dips to 20°F (-6°C) and are a favorite for container growing.
Cold weather doesn’t mean giving up on citrus! By choosing hardy varieties and providing the right care, you can enjoy homegrown citrus year-round.
