i have a few different varieties of beans, i have a wigwam already built but do all varities need something to climb up?

[JayG]

Climbing beans do, bush or dwarf types will probably need a bit of support, especially on exposed sites.

Peas need support but tend not to grow up individual canes.  Use pea netting or string to surround them.

i have a structure with netting does it matter if different varieties climb up it together and cross? sorry if that doesnt make sense

Other threads about this are around --- very slight chance they will cross pollinate but it doesn't affect the eating quality

If you save seed for the next year though, you may get some surprises, maybe not.
