tomato (yellow pear).
(The uber-leggy ones at the bottom are tomatillos.)
I've done almost all of my thinning now; only a few rows remain (the ones in the upper-left of the last picture). I've replanted some leggy seedlings (with more care than before). The cabbage is mostly in control, but I don't know what to do about the tomatillos. They seem to survive anything though, based on last year (in which I got a decent crop despite not hardening my plants off, extreme heat, hurricane, and flood). My gut says to just let them do their thing.
