Hardy in USDA Zones 2-9

Annuals

Produces pods (non-edible) with 8 very sweet peas 

Sun requirements: Full sun although tolerant of partial shade. 

Water requirements: Water very deeply at least once a week, especially during hot weather. Avoid frequent, light waterings. 

Space requirements: Sow 2 inches (5 cm) apart, with 25 inches between rows. Plant about 1.5 inches (4 cm) deep. 

Soil requirements: Fertile, well-drained soil

Possible Companion Plants: Eggplant, radishes, peppers 

Start date: Direct sow between March and April. 

Thinning: Thin plants around 2 inches tall. 

Staking: Provide support, such as a trellis, rope trellis, or fence, when peas reach 5 inches tall. 

Harvest: Continually harvest peas to encourage high production. 

Diseases: Powdery mildew is a common problem with leaves. Make sure plants have good ventilation. Treat with neem oil. 

Hardy in USDA Zones 6-11, although grows best in areas with a long, frost-free season 

Perennial, although usually grown as an annual

Edible parts: the seeds

Sun requirements: Full sun! As sunny a spot as possible. 

Water requirements: Peanuts require 1 inch of water per week. Watering is especially important immediately after germination and about 60 days after germination, when the plant begins producing the seed pods containing peanuts. 

Space requirements: Sow peanuts two inches deep and eight inches apart. Leave 18 inches between rows. 

Soil requirements: Loose, well-drained, sandy soil with well-aged compost. 

Possible Companion Plants: Potatoes and eggplant. Be careful not to plant tall plants next to peanuts, as they don't tolerate shade. 

Start date: Direct-sow peanuts when the soil temperature reaches 65 F (usually around mid-April for DC). However, it's most important to make sure the plant has 130-140 frost-free days. If starting in mid-April puts the peanuts of danger of experiencing frost, start the peanuts inside in mid-March and transplant outside. 

"Pegging Down": After flowering, the place will produce small shoots that reach towards the ground. After reaching the soil, these shoots will produce peanuts. 

Harvest: When stems turn yellow, or 130 days after germination, pull the entire plant up gently. Allow the peanuts to dry for a few days before removing the shells from the plant. 

Diseases: Pod rot (pictured) is a general term for mildewing or decay of the pods while in the ground. Make sure soil is well-draining and avoid excessive watering. If necessary, apply fungicides.
