I read that to attract bumble (and other) bees to your tomatoes to pollinate them, you can mix 1/2 cup sugar with 1 gal of water and spray the tomatoes. I have two questions about this: 1. Wouldn't this attract pests as well? 2. When mixing for a humming bird feeder, to mimic natural necture the ratio is 1 part sugar to 4 parts water---isn't 1/2 cup to 1 gallon too weak to attract bees?
Thanks in advance
