Planting Yard-Long Bean
Yard-Long Bean is a warm season vegetable in the Fabaceae family. Getting the timing right is the difference between a strong stand and a disappointing one, so the windows below are given relative to your own last spring frost and first fall frost rather than a generic calendar date. Look up your local frost dates and count back or forward from there.
Sow Yard-Long Bean directly into the garden 2–3 weeks after your last frost, once the soil has warmed.

Days to Maturity
Yard-Long Bean reaches maturity in 70–90 days from sowing. Once ready, plants continue producing for approximately 45 days.
Yard-Long Bean is ready to harvest after about 80 days. Picking regularly over the roughly 45-day harvest window keeps plants productive and encourages a longer pick. Harvest before the first fall frost, which will end the plant's productive season.
Conditions and Care
As a warm-season vegetable, Yard-Long Bean needs warm soil and settled weather to thrive, and is set back or killed by frost. It is frost tender, so wait until all danger of frost has passed before planting out and harvest before the first fall frost.
Yard-Long Bean needs full sun — give it at least six hours of direct light a day for the best growth and flavor. Sow seed about 1 inch deep, then keep the soil evenly moist until seedlings establish.
Yard-Long Bean belongs to the Fabaceae family; rotating where you grow members of this family each year helps limit the build-up of soil-borne pests and disease. Yard-Long Bean is generally grown as a single planting each season rather than succession sown.
