This has been a very bad year for the summer garden. The extreme heat and humidity in July caused us to abandon weeding, with predictably disastrous results. Out of desperation my husband mowed a path through the garden, which instantly turned the mowed area back to lawn: don't ever use a lawnmower in your garden! Bad storms, one of which found me trapped in a car in the driveway with my son while golf ball-size hail fell, badly damaged the tomato plants because my husband had tied them to multiple stakes (so when the stakes went in different directions, the plant was broken). The bugs, like the weeds, loved the hot, humid climate.
This is what did or are doing relatively well in 2012: onions, early-planted potatoes (we were especially pleased with King Harry), peppers, tomatillos (including some volunteers), roselle, lemon grass, field peas, gourdseed corn, huazontle, sunflowers (volunteers from seed we fed the chickens).
These things were a relative or total failure: late-planted potatoes, tomatoes, pole beans, squashes (although there is some kind of volunteer squash that has taken over the entire lower story of the corn patch), artichokes, melons, gherkins.
These things we don't know about yet, but don't have high hopes for: peanuts, sweet potatoes.
The only thing I have preserved from my garden this year is a chile verde (tomatillo/onion/jalapeño) cooking sauce.
