Re: Citrus (was non sqft questions)


     
Hi Martha and Doreen,

I am in So. Cal. in zone 9b or Sunset zone 19. Since we are inland, we do get 
occasional frosts, and as you may have read, OldJohn said he had one a few weeks
ago and so did we. The night before, I just throw an old sheet over the Meyer 
lemon (small) and the Mexican lime (still young). The sheet doesn't seem to get 
wet or freeze, at least I haven't noticed any real bad frost leaf damage.
Good luck,

About Martha's Ponderosa lemon question.  Yes, a pot will do nicely.  I'm in 
zone 9 just south of Houston and grow an Owari satsuma and a Bloomsweet 
grapefruit in plastic pots.  Just remember that citrus does not like to be 
in pots that are much bigger than their root ball.  They rot in large 
containers.  So move up the tree every year to a container only slightly 
bigger than the old one.  Also, if you want to put the tree in the ground, 
you can erect a frame around it for the winter months.  When temps dips 
below 30 degrees, stretch clear plastic over the frame and make greenhouse. 
I have several citrus-enthusiast friends who rig elaborate hoops over their 
rows of trees and cover the hoops with clear plastic.  Just be careful that 
the plastic doesn't touch the tree leaves--frozen plastic contact will kill 
them.  But, you can just prune away the damaged part. Another way to stretch 
the zone is to position the tree in the lea of a north structure to break 
the wind and cold.  If the wall, fence or whatever is brick or concrete, 
even better, because it will act as a solar energy trap.  go for it!
