I transplanted
two beds of broccoli
last Thursday then three more a day later. As expected, it
frosted both Friday and Saturday night --- I can't tell you how cold it
got since our exterior thermometer is still inside the collapsed
refrigerator root cellar, but I'd say it got into the
high 20s. All of my broccoli seedlings got nipped, but the ones
transplanted on Thursday were only midly damaged while those
transplanted on Friday ended up on death's door. See for yourself
--- here is a typical Thursday seedling:
And here's a typical
Friday seedling:
I suspect that the
Friday seedlings were still dealing with the worst of their transplant
shock when the frost hit, while the Thursday seedlings were in prime
condition. If I had it to do over again, I would have
transplanted earlier in the week to give the seedlings more time to get
situated. I wonder if the seedlings wouldn't have been damaged at
all if they'd had a few more days to get their roots under them?
Good thing I've got
spares! I replaced all of the badly nipped seedlings and put out
a couple more beds' worth Monday evening. No frost is forecast
for the next week, so they should do fine.
