tomatoes at the bottom to see everything. These need
to be ordered in sets of at least 3 per item, with a small
discount for 12 of the same item.)
Laurel:

Darrel and Laurel probably have the best selection of
heirlooms.
You could also try staking them up with a stick and twist tie
and then foliar feeding them to see if they recover. For a
really drastic attempt, mix up some 1/4 strength Miracle Gro
or similar, dig up the injured ones, and dip the whole plant
upside down in the fertilizer solution, then plant back in its
container, stake it up, and water it in. (It is still going to need
cold weather protection for a couple of days.)
