Planting and Harvesting Calendar for Gardeners in Yuma County

There are two distinct growing seasons in Yuma. The first, extending from September through February, when the sun is low and the days are short, is ideal for growing cool season crops. The second growing season, extending from March through August, when the sun is higher in the sky and days are longer is ideal for growing warm season crops. The cool season is best for growing non-fruiting plants such as lettuce, spinach, broccoli, cauliflower and cabbage. These crops thrive during cool weather and can survive the occasional light frost that occurs in Yuma. The warm season is the best time to grow fruiting crops such as tomatoes, squash, melons and peppers, which can handle the warmer spring temperatures.
