I usually sow the seeds very close together. You can eat it raw like baby spinach. Be sure to harvest the turnip roots if you thin those. Collards will eventually need to be thinned to about 1 plant per 12 inches
Then I've definitely planted them too close. Yours is the closest row to the fence, split into 3 for the 3 types you sent.
I need to come to dinner at your house. That sounds lovely.
Dsqard, perfect photos as always. Enjoy the trip today.
