Catnip Herb
Sowing:
Catnip grows best in well drained soil and full sun, though it can tolerate almost any soil. Direct sow the catnip herb seeds after the last spring frost, planting them 1/4″ deep in rows 20″ apart; when the seedlings appear, thin to 12-15″ apart.
Growing:
Keep the soil uniformly moist until the seedlings are well established. Since cats will crush the seedlings, protection may be necessary until the plants have grown to a moderate height. Control weeds. Pinch off flower heads for more leaf growth.
Harvesting:
Single leaves or stems can be harvested as soon as the plant reaches a height of 8″. For best flavor, harvest in the morning after the dew has dried. Use fresh or dried; for best results, dry in an oven or dehydrator. Keep dried leaves in an airtight container.
Seed Saving:
Catmint prefers well drained soil and full sun, though it can grow quite well in almost any soil. Direct sow the Nepeta Cataria seeds after the last spring frost, planting them 1/4″ deep in rows 20″ apart; when the seedlings appear, thin to 18-24″ apart. Catmint also grows well as a container plant. In the garden, catmint repels pests such as ants, aphids, and mice.
Common Pests:
Aphids: The common name for many species of aphids that infect gardens is plant lice, as that is exactly what they look like. Aphids sucks plant juices, weakening the leaves and the stems. Fortunately there are a dozen major predators to every type of aphid. The most common predator are the lady beetle, small wasps, syrphid fly larvae, and lacewings. Most of the time insecticide is not needed for removing aphids, a strong stream of water from the hose will do just fine, as will soapy water.
