Growing Nepeta, commonly known as catmint, from seed is a rewarding process that adds fragrant, bee-friendly blooms to your garden. With its hardy nature and low-maintenance requirements, Nepeta is ideal for both novice and experienced gardeners. Follow these 5 easy steps to successfully grow Nepeta from seed and enjoy its lush foliage and vibrant flowers.
Step 1: Gather Your Supplies
Before you begin, ensure you have all the necessary materials: - Nepeta seeds: Choose a variety like Nepeta x faassenii or Nepeta racemosa for their hardiness and beauty. - Seed trays or pots: Use small containers with drainage holes. - Seed-starting mix: A lightweight, well-draining mix is ideal. - Plastic dome or cling film: To create a humid environment for germination. - Watering can or spray bottle: For gentle watering. - Grow lights or sunny windowsill: Seeds need ample light to thrive.
Step 2: Sow the Seeds
- Prepare the soil: Fill your seed trays or pots with moist seed-starting mix, leaving a ¼ inch gap at the top.
- Sow sparingly: Sprinkle the seeds lightly on the surface. Nepeta seeds are small, so avoid overcrowding.
- Cover lightly: Gently press the seeds into the soil or add a thin layer of mix on top. Nepeta seeds need light to germinate, so don’t bury them too deep.
- Mist with water: Use a spray bottle to moisten the soil without disturbing the seeds.
Step 3: Provide Optimal Conditions
Nepeta seeds germinate best in warm, humid conditions: - Temperature: Maintain a consistent temperature of 65–70°F (18–21°C). - Humidity: Cover the trays with a plastic dome or cling film to retain moisture. - Light: Place the trays under grow lights or in a sunny windowsill. Aim for 12–16 hours of light daily. - Watering: Keep the soil consistently moist but not waterlogged. Use a spray bottle to avoid overwatering.
Step 4: Transplant Seedlings
Once seedlings have developed 2–3 sets of true leaves, they’re ready to be transplanted: 1. Harden off: Gradually acclimate seedlings to outdoor conditions by placing them outside for a few hours daily over 7–10 days. 2. Prepare the garden bed: Choose a sunny spot with well-draining soil. Amend with compost if needed. 3. Space appropriately: Plant seedlings 12–18 inches apart to allow for growth. 4. Water thoroughly: After transplanting, water deeply to help the roots establish.
Step 5: Care for Mature Plants
Once established, Nepeta is a low-maintenance plant: - Watering: Water regularly during the first growing season. Once established, it’s drought-tolerant. - Pruning: Trim back spent flowers to encourage continuous blooming. Cut back by one-third in late summer for a fall rebloom. - Fertilizing: Apply a balanced, slow-release fertilizer in spring if needed. - Pest control: Nepeta is generally pest-free, but watch for aphids and treat with insecticidal soap if necessary.
