Growing Citrus in RVA

In Richmond, VA citrus plants are grown indoors and are NOT cold hardy. Citrus in our area can be put outside during the summer months but should be brought in as soon as temperatures begin to drop in the evening. Citrus plants do well in containers, making them easier to bring in and out of the house – just be sure your pot has holes in the bottom for proper water drainage.

Citrus do best in a loamy/sandy soil – heavy soils with moisture control or that drain poorly can create a multitude of issues for citrus plants. We often suggest a cactus soil or an amended potting mixture to improve drainage. A major benefit to growing citrus plants is that they do not require much pruning. Keeping the deadwood or unsightly new shoots cut back is okay.

Citrus plants are heavy feeders – requiring a substantial amount of Nitrogen. We suggest using Espoma’s Citrus Tone to feed your lemons, limes, and other assorted citrus. Apply citrus tone according to the bag’s application rates instructions in late winter prior to fruiting, late spring right after bloom and again in the fall to support overall health.

Citrus needs significant heat to ripen fruit (between 70–90-degree Fahrenheit). Blooming and fruiting is dependent on both light and heat. If a citrus plant does not receive enough light/heat it will produce foliage but not flower/fruit. Place your citrus plant in an area that receives significant light (south-facing window is best). Avoid placing your plant too close to a window that would get cold in the winter months.

Citrus also needs a consistent watering schedule during the fruiting stage. Sudden changes in lighting or humidity can cause issues; Be sure to gradually change environmental conditions.

Why are my blooms or fruit dropping?

Young fruit may drop in May, June and/or July. Some fruit drop is natural. Excessive drop may be due to drought stress, low humidity, or nitrogen deficiency. Heavy pruning, thrips, mites, or spray injury can also cause fruit to drop. Fruit drop is a self-regulating response in citrus trees. Be sure to remove mature fruit; leaving mature fruit on the tree could cause more fruit drop or smaller fruit during the next crop.

Be aware that some varieties of citrus go through alternate bearing – they produce a lot of fruit one season and not the next. For example, Florida Valencia oranges and Karsh grapefruits typically present alternate bearing.

Most citrus trees grown indoors or outdoors are self-fruitful, including oranges, grapefruit, kumquats, lemons, and limes. However, some mandarin orange varieties produce more fruit with cross-pollination, but those fruits may have more seeds than those that self-pollinate. Plants that grow from seeds of cross-pollinated citrus might not bear fruit.

There are HUNDREDS of varieties of citrus. Below are a few that are most commonly mentioned/grown:
