Nepeta or catmint is one of easy to grow perennial and it grow in zone 3. It can be propagate from seed, cutting or layering. But the easiest way is from cutting .
- In my experience , I propagated Nepeta x faassenii from seed on March 1st in the heated greenhouse. Sow 5 to 8 seeds per plug or 4" pot on good seeding mix, cover by plastic to create humidity. Seed will germinate after 1 to 2 weeks. After first leaves appear, pull out the weak seedling, and fertilize with fish emulsion or starter fertilizer twice for a month. Hardening off seedling when temperature above 10 deg C. I done this in the second weeks of May. Transplant seedling in the garden after danger of frost.
- I propagated nepeta from cutting too. This is the easiest way to propagate the plant and can be done anytime from early spring until August, so the plant can have time to establish the root before first frost coming. Take cutting about 4 " below the leaf node, and strip all lower leaves but the top one to reduce moisture lose. Dip the cutting end tip on rooting hormone and put on the seeding mix or good compost. Cover the pot by plastic or put in the propagator. In about 5 to 7 days, cutting should have root ready. Leave it for 2 or 3 days in its pot then transplant the plant to individual pot or straight in to the garden. Nepeta is fast growing plant and hardy to zone 3.
