Transplanted more PT buckwheat -- this time into NE corner of central bed, by pulling kale but leaving roots

Cleared out most of the NE central bed's kale, and some of the chards, mostly by chopping them down to just the stem poking out (to let the roots decompose in place, and also to see if they re-grow).  Then transplanted the PT-sprouted buckwheat in amongst the kale stems.
