It is unlikely that the honeybees will get in there and pollinate these. All are native to the United States, and developed using other techniques for fertilization. Corn is usually pollinated via the wind: the tassels and the corn silk get mixed up via summer breezes. The squash has a specific bee that moves their pollen around..early in the morning while the honeybee is still snoozing. And beans have a variety of little bees on them, bot usually honeybees.
Here is what is planted. We could hardly resist these old, non-hybrids..such great names..
Stowells Evergreen Corn
Blue Coco Bean
Lazy Wife Greasy Bean
Hopi Dye Sunflower
Silver Queen Corn (the one hybrid we grow..too delicious not to!)
Cherokee Cornfield Bean
Grey Tender Zucchini
Mammoth Russian Confectionary Sunflower
there are squash and melons in there too..
noir de Carmes Melon
Honeydew Orangeflesh Melon
Queen Acorn Squash
Sugar Baby Watermelon
Small Sugar Pumpkin
Green Striped Cushaw Winter Squash
Delicata Zeppelin Winter Squash
so now we must be vigilant and pick the bugs off, so the plants can produce a harvest!
