Bean Cross pollination

[Hellolittlebeastie]

Hey so sorry me again!

So due to what's currently going on I'm not sure if my newest raised bed supplies will arrive and I was also counting on buying lots of pots this year which I now can't do.

I usually grow runner beans and peas in 1 bed and they seem to get along fine but this year I've got runner beans, peas, Mange Tout, Jack Edwards French beans, 'normal' French beans, butter beans and chickpeas. Will this cause cross pollination between crops? I'm also wondering if the same happens with pumpkins and squash as I have a green pumpkin and hokkiado squash that I was hoping to put side by side but not sure if this is possible!

I know you can't put different varieties of sweetcorn together but not sure what other plants this is relevant with. Please can someone advise? Thank you!

Cross pollination is only problem if you want to save seeds from the plants - although peas and French bean seeds are normally OK to save anyway..

Peas (Including Mangetout) and any variety of French beans self-fertilise themselves within the flower, so rarely cross, although it isn't impossible. Sorry I know nothing about chickpea pollination - although it is called a pea it's from the bean family
Butter beans will cross with runner beans.
The pumpkin family don't cross with Hokkaido squash, so you should be ok there.
