Growing Citrus in a Greenhouse/Solarium

Most citrus can be grown and fruited in greenhouses or solariums. Simulate a subtropical environment by keeping temperatures between 55°-95°F, with some humidity.

Midsummer shading in a greenhouse may be necessary to hold temperatures below 100°F. Shade cloth may be helpful to reduce greenhouse temperatures when draped over the structure.

Conversely if winter conditions are excessively dark and the resources allow, consider supplementing with grow lights. If your growing space receives at least 5-6 hours of full direct sun per day, supplementing with full spectrum bulbs or fluorescent plant lights can help trees perform well. IF, however, the space provides less than 5 hours per day of direct, full sun, more sophisticated grow light systems may be necessary. ACF Greenhouses is a good online source for helpful information about grow light systems.
