About Mustard Greens

Mustard greens are one of the fastest crops in the garden — ready in 4-6 weeks with a spicy, peppery kick. Huge in Southern US, Indian, and Asian cuisines.

Direct sow in early spring or fall — hot weather triggers bolting and extreme bitterness. Harvest outer leaves continuously. Baby leaves at 3 weeks are excellent for salads. Grows well indoors under lights.
