Danvers 126 Half Long Carrots --- no damage
Chinese cabbage siu choy (紹菜) --- no damage
Chinese kale (芥蘭) --- no damage
Sugar snap peas --- slightly droopy leaves, minor damage
Fava beans --- slightly droopy leaves, no damage
Napa cabbage seedlings --- pleasantly surprise, no damage.
Here are some of the vegetables endured 18F (-7.78C) freezing temperature last night (will they survive 2 more nights of freezing temps?) These pictures were taken around 10:30 a.m. this morning at 23F (-5C). None of the vegetables received any protection from floating covers or mulch, I want to test their cold tolerance to see how far I can push them and what to expect next year.
The carrots and brassicas are the strongest of all, sugar snap peas suffer minor damage, I picked the shoots for lunch this afternoon just in case it won't make it through tonight's freeze. The cold tolerance experiment is very encouraging, it indicates the Chinese cabbage and radish plus all other brassicas will be able to withstand cold down to the teens for short periods of time, which means I can overwinter these crops if given adequate protection from cold.
1:40 p.m. Shortly after posting the above message snow and wind pound at the surviving plants, will my babies live?
