Could someone please let me know which bed the squashes
(marrows,pumpkins in particular) belong in a
Aliums/Brassicas/Legumes/Roots rotation system.

Squashes are in the Cucurbitaceae family which includes cucumber,
courgette/marrow/zucchini, melon and pumpkin. If they are grown
regularly in soil, they should be given separate rotation from alliums,
brassicas, legumes, roots or the solanum family.
