Peas will sprout in 21 to 30 days if the soil temperature is 38 degrees Fahrenheit and the germination rate, or number of seeds that do sprout, will be low. At temperatures of 65 to 70 F the seeds will sprout within 7 to 14 days and the germination percentage will be in the high 90s for fresh seed.
Peas are ready to harvest in approximately 60-70 days. When pods of the peas appear to be swelling with rounded pea forms visible, they are ready for picking. Take a test picking every day or so, and note the appearance of the pods with the sweetest peas. If the pods are left on the vines too long, they become tough and starchy. Pick black eyed peas slightly before maturity. They should still be a light green with a purplish eye. They are still easy to shell at this stage and taste delicious.
