Do you recommend a smothering cover crop?

ECHO corresponded with community member Glenn about Jack bean (Canavalia ensiformis) as an option for smothering weeds. Slow-growing and erect, not spreading, we could use it for crowding out weeds and grasses in orchards. Other cover crops such as Velvet bean (Mucuna pruriens) send out vines and can climb up trees and take over orchards if one is not careful! We may need to plant jack bean closer together, at 6-8 inches (15 -20 cm), to achieve a higher Leaf Area Index, LAI, and out-compete weeds and supplement nitrogen needs. Do you have experience with using jack bean or other weed-smothering crops that you'd like to share with Glenn?
