Depends somewhat on your location. All Blueberries require a low pH ( 4.5 -5.5)
and a loose friable soil. Good planting holes are a must. If your pH is too
high it can be brought down with sulphur. Leaf mold compost is ideal for
improving the quality of the soil. They are not heavy feeders so use fertilizer
( even cow manure ) sparingly. They also need to be mulched. Pine straw is
excellent. If you are USDA zone 6 or lower you can use the typical cultivars
found in seed and nursery catalogs. USDA zone 7 or higher you will need
rabbiteyes or southern highbush cultivars. so anyone have any ideas for a
hearty climbing vine
that doesn't need much direct sun? I thought about scarlet runner
beans, but I'm not sure how well they would do in a shaded area.

As for a climbing vine with edible fruit, you might try regular pole beans (P
vulgaris) if you prefer the showy blossoms of P. Coccineus then there are
several newer cultivar of the runner beans that are better than Scarlet Runner,
Painted Lady (pink and white varigated blossom) and Goliath ( scarlet blossom)
come to mind. If you can use a perennial, perhaps grapes or kiwi can fit the
bill. of course there are lots of other options.
