About this guide

Covers garden cress (curled types), upland cress and watercress, which grow quite differently.

Garden cress

Sow thinly, about 20 seeds per inch, in a 2–4" band outdoors from early spring to early fall, or indoors in a flat at any time of year. Start cutting at about 2" tall, 7–10 days after sowing, and sow again every 2 weeks.

Upland cress

For full rosettes, sow outdoors from mid-spring on, 1/4" deep and about 15 seeds per foot, and keep the soil moist, since germination is slow. Thin to 4–6". Cut rosettes just under the base. For baby leaf, sow 3–5 seeds per inch in rows 2" or more apart and cut above the base at the size you want.

Watercress

It needs so much moisture that direct sowing is tricky. Either sow 1/4" deep and about 1/2" apart, thin to 4" and water often, or start seed indoors in moist mix. Move plants to large pots, a cold frame or a bed with fertile, humus-rich, limed soil near pH 7.0. Keep the soil wet, or stand pots in trays of water changed daily.
