Mild Winter Areas — Zones 7b–9a
April is a peak planting month in mild-winter zones as soils warm and frost risk fades, opening the door to a much broader range of crops outdoors. Continue sowing cool-season favorites in early April, when nights are still chilly, and begin transitioning beds to warm-season planting throughout the month as temperatures stabilize. Succession sowing, trellising, and a little frost protection for surprise cold snaps help keep growth steady — and April is also an excellent time to harden off seedlings and get transplants established.
Indoors (fresh harvests):
- Microgreens: peas, broccoli, sunflowers, arugula
- Sprouts: alfalfa, broccoli, radish, mung
- Herbs & greens under lights: chives, parsley, mint
Transplants to move outdoors (weather permitting — harden first): pepper, tomato, eggplant, melons, basil
Crops that can be directly sown outdoors in April: cucumber, squash, beans, corn, melons, okra, cowpeas, plus replanting for many greens and root crops
Cover crops: buckwheat, cow peas, sorghum
Tip: An Olympia, WA zone 8 is very different from a Jackson, MS zone 8. Consider checking with your state Extension Service office for more specific recommendations and guidelines.
Use your USDA zone as a guide. Microclimates matter—coastal/urban spots run warmer; high elevation runs colder.
