I've got a little 350 sq ft garden and last year I was pollinating zucchini by hand because there weren't very many bees around. (It made me feel kind of dirty to be sexin' up the vegetables with a Q-tip)
This year I've got a hive about 200' from the garden and the garden is alive with the sound of bees!
The Crane melons and Charentais melons are blooming heavily right now and there's a bee butt sticking out of almost every flower.
