Daytime temperatures should be above 70 degrees. Most citrus varieties will begin dropping their leaves when temperatures dip below 50 degrees Fahrenheit at night, so be sure to keep your greenhouse environment above that. Citrus trees tend to be top-heavy, and a deep pot keeps them balanced. The most important thing about the pot is that it's deep. If you've got a particular favorite and have the room for it in your greenhouse, place it in a larger pot so its roots will have plenty of room to grow. Keep in mind that the bigger the pot, the larger the tree will eventually get. Choosing the ContainerĬontainers used in home greenhouse citrus production should be at least 10 gallons. Remember that agricultural researchers are coming with up with new varieties on a regular basis, so always ask a knowledgeable nursery professional for current recommendations concerning which types are best suited for your particular need and preferences. They don't take up nearly as much room, the fruit is the same size of that found on standard varieties, and they're not quite as prolific. Selecting the Varietiesĭwarf varieties exist for all citrus trees and are far better suited for home greenhouse cultivation than their standard-sized counterparts.

Although lemons, oranges, and limes are the most popular types of fruit grown in home greenhouses, it's also possible to produce tangerines, clementines, kumquats, and grapefruits. Once you've had a greenhouse-grown orange, you'll never look at the ones in supermarket produce bins the same way again.

Citrus trees such as oranges, lemons, and limes are generally quite easy to grow in greenhouse environments and offer a great way to enjoy the freshest possible fruit.
