Edamame: Sowing, planting and harvest calendar
When and how do you sow edamame under cover?
Sow edamame under cover in mid to late spring, a few weeks before outdoor planting becomes possible. Young plants need warmth and cannot withstand frost. Very early sowing may leave them confined to small pots for too long while the outdoor soil remains cold.
Choose vegetable soybean seed suited to the length of your summer. Fill pots with drainage holes or reasonably deep modules with moist, freely draining seed compost. Put one seed in each container at the depth stated on its packet. Recommendations vary with seed and conditions, so do not simply leave this large seed on the surface.
Water gently and keep the mix moist rather than saturated. A temperature of about 18 to 20 °C suits germination under cover. Remove any transparent cover as soon as seedlings emerge. Then keep them warm and in strong light so that their stems do not become long and weak.
Watch root growth and do not leave plants cramped in small containers. Gradually prepare them for outdoor air before moving them out permanently. Planting must wait until frost risk has passed and the soil has warmed sufficiently. One pleasant afternoon alone does not establish that those conditions have arrived.

Weed
If weeds are competing with your young plants, remove them before they take over. Close to the plants, work by hand without disturbing the soil deeply to protect the roots. A weed-free row needs no action.
