'Three sisters' planting

[UtterlyUnimaginativeUsername]

So I was reading about the 'three sisters' thing that native americans traditionally did with winter squashes, corn and beans as companion plants, with the beans climbing up the corn to give it more stability in wind, the corn giving the squashes shade and the squash leaves keeping the area moist and weed free. I'd love to give it a go but I've read elsewhere that winter squashes can struggle a bit here (I'm in Ireland) because our summers are so pants, so presumably the three sisters is a no-no for me because the last thing I want is corn shading my squashes?

Disclaimer: I haven't grown any of these before so I haven't a clue what I'm talking about; this is all planning for a house move to somewhere with the land to accommodate stuff.

the thing is, we're not in Mexico!

I considered it this year but with runner beans as that's what I'd heard about but the sweetcorn would have needed to be planted out several weeks ahead to be strong enough to hold up the runner beans, peas might be better as they are much smaller, weaker plants. However it might be tricky picking them as you need to plant sweetcorn in a block not a row for pollination purposes. I did let cucumbers ramble about under the outside rows of my sweetcorn where I could reach in between to pick them.
