Re: non sqft questions

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!
