I want to plant the 3 sisters, corn (maize), beans and squash, for my zone (9b) both beans and squash can be planted in Aug/Sep but I've missed the cut off for sweetcorn. Has anyone had experience of planting maize in this climate at this time? Will it work or am I likely to be disappointed? Thanks for any help. Katie

Depends why it is bad to grow it with it. Some anti companion plants attract the same bugs while others emit natural chemicals that hinder each other, some cross pollinate or need different conditions from one another. I do not know why Celery should not be planted with corn but 10meters should be plenty Have you tried an Aztec plot when growing corn? 3 crops from same patch. 16 corn 3 squash, zucchini or pumpkin and 1 bean growing up each corn plant (for nitrogen) per meter square. - Ferran
