University of California Agriculture and Natural Resources released on Apr. 27 a guide for planting warm-season vegetables in May, highlighting optimal conditions for both transplanting and direct seeding during this period.
The timing of planting is important because temperature fluctuations can affect seedling growth. The guide recommends adjusting practices based on local weather, such as delaying transplanting during warmer periods or providing shade, while cooler temperatures may only slow new growth. Consistent and deep watering is advised as the weather warms to ensure healthy vegetable production throughout the summer.
To improve pollination for crops like squash and melons, which require both male and female flowers to be pollinated, the guide suggests planting bee-attracting plants such as borage. Staggered seeding of corn and beans every few weeks is also recommended to extend the harvest season.
Recommended vegetables for April in Yolo County include lima beans, corn, cucumber, melon, and squash by seed or transplants. Additional recommendations for the Sacramento area cover green beans, celeriac, chard, chives (seed or transplants), eggplant (transplants), okra (seed or transplants), multiplier onions (bulblets), peppers (transplants), sweet potatoes (slips/transplants), pumpkin (seed), radish (seed/daikon in first two weeks), soybean/edamame (seed), spinach (seed), winter squash (seed), tomatillo and tomato (transplants) as well as watermelon by seed.
