A Garden Update

The vegetable garden is coming along. The tomato plant is four or five times the size it was when I planted it last month and it has at least a dozen tomatoes and even more blooms:

I've never grown a bell pepper before, so I really don't know how it's doing, but it seems to have some developing fruit (I'm not sure if you can make them out here):

The zucchini seems to be having the same problem it did last year—the fruit is dying before it matures:

It grows to about 2 inches, then turns yellow and shrivels up. I tried all sorts of things last year, but none of them worked. If you have any suggestions, I'd love to hear them.
