Windows: UA Cooperative Extension, Vegetable Planting Calendar for Maricopa County (az1005, 2018), the closest published calendar for the City of Maricopa. Plants per square: square-foot gardening guides from UC and NC State Extension. Your frost risk is higher than central Phoenix, so keep frost cloth handy for young plants from late December on.
My crops
Check the crops you grow and pick seed, transplant, or both. Add varieties under each crop. A variety can carry its own days to harvest and spacing from the seed packet.
