- Light shade can support beans, beets, broccoli, cabbage, cauliflower, chard, kohlrabi, leaf lettuce, peas, potatoes, radishes, rhubarb, spinach, and turnips, but harvest size or form may be reduced.
- Fruiting vegetables may benefit from afternoon shade during hot periods, while poorly drained, thin, sand, or clay sites may need raised beds or container gardening.

Climate signals
- Oklahoma Garden Planning Guide, Published Feb. 2021, Id: HLA-6004, by David Hillock and Brenda Sanders, says a successful site has full or near full sunlight, deep, well-drained, fertile soil, and a water supply.
- Light shade can support beans, beets, broccoli, cabbage, cauliflower, chard, kohlrabi, leaf lettuce, peas, potatoes, radishes, rhubarb, spinach, and turnips, but harvest size or form may be reduced.
- Fruiting vegetables may benefit from afternoon shade during hot periods, while poorly drained, thin, sand, or clay sites may need raised beds or container gardening.
- Cool season vegetables do best when average daily temperatures are 70 F or less, and warm season vegetables do best at 70 F to 90 F.
- The guide groups vegetables as hardy, semi-hardy, tender, and very tender, and says differences in suggested planting dates range from earliest for southeast Oklahoma to latest for the northwest.
Planning notes
