Yard carrots a total flop -- won't do another round, will just put something else there

Wow, despite all my effort with the vermiculite under/over and the corn starch gel, and covering with burlap, the yard carrots were a complete and total flop.  Not a single carrot.  So, for the first time in many, many years, I'm just not going to grow carrots in the yard.  GA will be the carrot place this year.

I'll theorize that the corn starch gel was too think and the carrots couldn't break through.  (It was a different batch of gel than the GA carrot sowing.)
