Cold burned bok choy seedlings.
The seedlings in this pot held-up better,
some rebounded from the cold.
After 3 days of indoor nursing.
BC seeds sprouted outdoor in a raised bed despite the cold.
I harvested all the cauliflowers 3 days ago, they seem to stop growing in the cold, the heads were small about the size of a baseball and tennis ball, next year I'll have to start planting them a lot earlier so they will size up by the end of October.
I left the bok choy seedlings outside on Thanksgiving Day and forgot to bring them indoor for the night, they were frozen when I saw them the next morning, my heart sank! The last picture shows the same bok choy seeds sprouted outdoor in the cold, the difference was the in-ground seedlings were under cover at night. This experiment confirms bok choys are quite cold hardy when they are left alone to fend for themselves, too much TLC actually harms them.
