COLD HARDY CITRUS






Citrus is one of the most favorite fruit trees to grow, and new cold-hardy varieties can be grown as far north as central Georgia, and along the Atlantic and Gulf coasts from Charleston to Houston. Citrus can also be grown easily in containers, so can be a great patio plant and brought indoors during cold days, or kept in a sun-room for the winter. The fragrance of citrus blossoms is one of the most wonderful perfumes imaginable, and picking fresh citrus and squeezing your own juice is one of the best joys in all of growing fruit!


Introduced to the New World by Christopher Columbus, there is a tremendous diversity in types of citrus. Citrus hybridizes readily and some of the very best types are hybrids. 

Some of the basic types are:


- Mandarins and tangerines - very hardy trees, originally from Asia, with segmented fruit with a wonderful tangy sweetness and skin that is easily peeled. Satsuma Mandarins have a very good cold tolerance system. They can survive in temperatures as low as 15 degrees F.

- Oranges - medium sized trees that are excellent for juice like Valencia, or the very hardy Blood Oranges with their  sweet red flesh and juice, or fresh eating fruit like Navel oranges. 

- Grapefruits and Pummelos - very hardy large trees, large thick skinned fruit, great for juice and fresh eating

- Lemons and Limes - small trees that are attractive ornamental; some are very hardy such as Meyer Lemons, and will take temperatures in the low 20s or even colder!  Limes are not very cold hardy they can get damaged in temperatures below 33F.

- Kumquats and hybrids - small very hardy trees, with small fruit that ripen year-round. Kumquats sweet-flavored skin is used in making marmelade, and Limequats, a unique hybrid, are dwarf trees that can be grown in a small space, and will withstand temperatures in the teens!


Nothing is easier to grow than citrus. Besides a good fertilization and watering program, they require little pruning, and have few pest problems. They continue to grow as long as temperature is warm. Planting in a warmer micro climate is the key to success, such as the south face of a house, on hillsides, near lakes or under overhead shade (such as under an oak canopy).

Most people lose their citrus trees in the first or second year of the tree’s life. It pays to protect these small trees during 25 degrees F or lower freezes. 

Here are some things to remember:
Cover completely with a two-layer combination of a blanket and then plastic. Uncover the next day as it warms up.
Once established, citrus trees can tolerate lower temperatures and recover more quickly from freezes.

The duration of freezing temperatures can be more critical than the minimum temperature. For example, serious damage may not occur during a brief drop to 24 degrees F, but could result after several hours at 26 degrees F. Moreover, previous exposure to cold increases the plant's ability to withstand cold. As the days shorten and nights get cooler, plants slow active growth an attain cold-hardiness. For example, Satsumas may withstand 15 degrees F in January when it is completely dormant and hardy, but it may be seriously damaged at 26 degrees F in mid- November.


Height: 10-20' (depending on type)

Tree Form: Bush

Pollination: Self-pollinating
Bears: All year (depending on type)
Light requirements: Full sun, partial shade for cold protection
Soil type: Well-drained pH 5.5-7.0

Watering: The first year watering is crucial for establishment of new citrus trees. Water thoroughly twice a week on light soils and once a week for clay soils. Soak the entire root system deeply.

Pruning: Prune in June/July to maintain height and thin out interior for good circulation. At anytime remove dead, damaged, crossed or diseased limbs, water sprouts or rootstock suckers. Trim back excessive growth to keep an even shaped canopy.

Fertilization: Citrus are heavy feeders. Use a good citrus fertilizer, fertilize in late February as the trees come out of dormancy, and again in late May and late July. Do not fertilize after August.
Maintenance: Easy
Hardiness Zone: 8b-10
