Tomatoes - doing excellent, I only have two plants, they are about 4ft tall now and one has little green tomatoes growing, both have lots of flowers - I did pick off flowers once or twice to get the bushes a little larger but have since stopped.
Peppers - plants didn't grow that tall this year. Mostly jalapenos, mostly about a foot tall. One green bell pepper is about 2ft tall, all have buds, most have flowered.
Cucumbers - I've got a lot, I bought some and grew some from seeds. The ones from seeds have finally started to take off, the started plants are growing in nicely.
Corn - growing like...well...corn. Different sizes when I got them mostly about a foot and a half tall.
Watermelons - growing, never had success in the past. Fingers crossed.
Carrots - just planted seeds a week or two ago, they're about an inch out of the ground now.
Sunflowers - also just started, just thinned them out yesterday, they're about 2-3 inches.
Lettuce - the seeds that I planted FINALLY started to get a little growth, they're maybe an inch and a half, planted about a month ago, give-or-take.
Looking at my list it seems like I have a lot, maybe I do, but it's no micro-farm like Dan has
