I planted a section of my garden three-sisters style this year: corn, squash/pumpkin, and pole beans (for dry harvest).
I also have a 25' row of "Mammoth Gray Stripe" sunflowers (9-12 footers) in the back of the garden where I've planted beans among the sunflowers. I had to saw down a similar variety of sunflower last fall, so I'm pretty sure these are going to be sturdy enough to carry a heavy load.
I started the corn and sunflowers first, thinking that they'd get a head start before the beans start to climb.
My question is: what's the right ratio of beans to corn/sunflower? I.e. how many vines is each plant capable of supporting?
