Grow Guide Conditions:
Cress prefers cool, moist conditions and does well in full or partial sun. Upland cress may overwinter even in the north before going to seed.
Grow Guide Seed:
Optimum germination occurs at soil temperatures from 60–70°F, but seeds will germinate at as low as 45°F.
Cressida is ready to harvest in as few as 10 days. For this reason it is often grown indoors all year round. Spread seeds thickly over moist paper towels in a shallow dish or tray and place in a spot that gets indirect light. Keep towels moist. Harvest sprouts with scissors.
Upland Cress can be seeded directly in the garden beginning in mid-spring. Plant seeds ¼” deep, 12-15 seeds per foot, in rows 12” apart. Keep moist. Thin seedlings to 4-6” apart.
Grow Guide Pests:
Cress is generally pest-free.
Grow Guide Harvest:
Cut leaves/sprouts with scissors as needed. Make succession plantings to ensure a constant supply. Cut leaves will keep in the refrigerator for about a week. Wait to wash them until just prior to use to prevent rot. Use a salad spinner to wash and spin dry or pat dry on clean towels. Upland Cress is often used as a substitute for true watercress in soups, butters and salads.
