Growing citrus in greenhouses

Posted by tiggermaxcocoa none (My Page) on

I live in high desert AZ (zone 8a), just outside of of a climate where citrus can live outside all year. I recently bought the small Harbor Freight greenhouse to house my potted citrus during the winter so I wouldn't have to worry about them. While it has been great as far as freeze/frost protection, something else unexpected has happened.

They EXPLODED with growth as soon as I put them into the greenhouse this winter, most likely as a result of the relatively hot temperatures inside the greenhouse during the day. Since we have cloudless skies nearly everyday, the temps in the greenhouse get into the 90s almost everyday, and then drop to 35-55F overnight. The trees obviously like it right now, but I'm wondering how their fruit production may be affected with such a strange climate.

Any input would be greatly appreciated!

RE: Growing citrus in greenhouses


Maybe you need to improve the ventilation so it doesn't get so hot. My greenhouse is in the 50-70F range for highs from Nov 1 until early March. I get good navels, about all I have now.

I can't say how it will affect your fruit. It depends on the cultivar. Some like more heat than others for best fruit quality.
