Growing citrus in the Southeast?

As edible landscapers, we get lots of questions about growing citrus. There is quite a bit of mystique around citrus cultivation, perhaps in part due to its ambiguous growing habit. As the climate warms up and we become a more solid zone eight in the Atlanta area, possibilities for various kinds of citrus increase. Also, the use of citrus is essential in a homesteader’s and herbalist’s kitchen; a backyard source is invaluable.

The most common and fail-safe method of citrus growing in zone 7/8 is to put a Meyer lemon (with relative freeze hardiness) in a large pot and bring it inside on the coldest winter days. They are fast growing, fruit abundantly, and tolerate a bright window indoors relatively well, especially if one watches for spider mites regularly.

But there are some intriguing hybrid varieties available that are showing impressive cold hardiness, such as crosses with the popular Asian Yuzu fruit with its complex and delicious aroma. I myself cannot seem to get enough of this rich, tangy and floral scent. A promising hybrid for North Georgia looks like the Yuzuquat, as reported by Tom McClendon. His web book Hardy Citrus for the Southeast provides and excellent overview for aspiring hobby citrus growers. Definitely check it out!

Planting outside is certainly the most practical method for harvesting year after year, and plant placement can have a lot to do with it’s success. Planting near a house at a southern or western aspect provides winter protection and access to the most sunlight. Mulching regularly, and watering before the coldest temperatures support a plant’s hardiness.
