Gardening lesson #1: Check on your heirloom tomato varieties for stuff like cracking and high yield. My larger tomato varieties (1884 and Ananas Noire) cracked like crazy and rotted on the vine. Nearly all those huge, previously lovely-seeming tomatoes hit the compost heap.
Gardening lesson #2: Canning red, pink, black, and yellow tomato varieties together in one can yields a jar of tomatoes that look sort of gross right off the bat. Maybe think about planting a more homogenous color mix if that is bothersome.
Gardening lesson #3: Plant more carrots. MOOOOOORE!
Gardening lesson #4: Be patient with the beets. Even if you’re excited, and even if you know that little beets taste good, let ’em get bigger.
Gardening lesson #5: Plant only one summer squash hill if short on space.
Gardening lesson #6: Artichokes might need more sun than they get halfway underneath a big sunflower.
Gardening lesson #7: Tomatillos — pick ’em when they’re a little yellowish, but not cracked yet.
Gardening lesson #8: Stay on top of the weeds.
