How to Plant Catmint Seeds
Sow seed in cell packs or flats, press into soil but do not cover. Light aids germination. Kept at 70° F., germination is in 14-45 days. Can direct sow (barely cover), in groups of 6-8 seeds spaced 12-18″ apart. Thin to the strongest plant.
Growing Nepeta: Full or part sun, prefers afternoon shade in hot areas. Well-drained soil. Blue Carpet prefers average to little water once established, can tolerate more sun in warm climates than Blue Dreams. Blue Dreams prefers average to ample water, tolerates more shade. Cut plants back by half after bloom, or cut flowering stems down to ground level. In spring, remove old growth to make room for new stems. Deer and rabbit resistant. Attracts bees and butterflies.
