Catnip (Nepeta cataria) - Key Growing Information
DAYS TO GERMINATION:
Seedlings appear in about 7–10 days at 60–70°F (16–21°C).SOWING:
Starting transplants is recommended. Sow 6–8 weeks before the last spring frost and cover with only a trace of vermiculite, since the seed needs light to sprout. Thin to one seedling per cell and pinch the tip for bushier growth. Plant out at about 3" tall, 12–18" apart.To sow outdoors, plant after the last spring frost or in early fall at 2–3 seeds per inch, pressing seed onto the surface or covering it very thinly, again because light aids germination. On a field scale, start with well-watered beds and roll the seed in. Space rows 18" apart and thin plants to 12–18".
LIGHT PREFERENCE:
Full sun.SOIL REQUIREMENTS:
Catnip grows nearly anywhere but does best in sandy soil.PLANT HEIGHT:
24-48".PLANT SPACING:
12–18" apart.HARDINESS ZONES:
Hardy in Zones 3–9.HARVEST:
Pick individual leaves once plants are established. From the second year on, you can cut back the top three-quarters of the plant. To dry, hang stems upside down somewhere airy, dry and out of direct sun.Note: Established catnip is very tough and reseeds freely.
