Protecting young citrus trees
With the cold nights a few weeks ago, I tried building some miniature greenhouses around my orange trees (about 3 feet tall each. Not a lot of dense leaves on either) using corrogated pvc (the scratchy looking kind, not clear). Since then their leaves are starting to turn yellow.
Should I remove some of the sides (keeping say, 2 sides/roof as windbreak), and use xmas tree lights/drop lights to keep them warm when the real cold hits?
I'm not going to be able to put blankets over the top of them at night because I don't get home from work until 11:30 pm.
Any thoughts on what to do to keep the orange trees alive through the winter?
