We pull the frost covers over to the side when it does not look like we expect frost. We enjoy growing citrus fruit and take the trouble to give them a bit of protection from the coldest nights. Citrus can be grown in a sunny spot next to your house so it will get both the sunshine needed to ripen the fruit and some warmth that leaks from the house at night. Many parts of our area grow fantastic citrus fruit and if your place has both frost protection and lots of sunshine be sure to feed well and often. If your garden has snails or slugs you will know by the holes munched in the leaves. Right now there are fragrant white flowers on the citrus - -what a dreamy smell.
