Growing catnip (Nepeta cataria) from seeds is a straightforward process. Catnip is a herbaceous plant that is well-known for its attraction to cats. Here's a step-by-step guide on how to grow catnip from seeds:
1. Seed Selection:
2. Planting Time:
Catnip can be grown indoors or outdoors. If starting indoors, sow the seeds about 6-8 weeks before the last expected frost date in your area. If planting directly outdoors, do so after the danger of frost has passed.
3. Soil Preparation:
Catnip prefers well-draining soil with a slightly alkaline to neutral pH (around 6.1 to 7.8).
Use a lightweight potting mix if growing catnip in containers.
4. Sowing Seeds Indoors:
Fill seed trays or small pots with the potting mix.
Sow the catnip seeds on the soil surface, pressing them lightly into the soil. Catnip seeds need light to germinate, so do not cover them with soil.
Water the seeds gently, and place the trays or pots in a warm location.
5. Sowing Seeds Outdoors:
Prepare the garden bed by loosening the soil and removing any weeds.
Sow the catnip seeds directly on the soil surface. Lightly press them into the soil.
Water the area gently to settle the soil.
6. Sunlight:
Catnip thrives in full sun but can tolerate partial shade.
Ensure that the plants receive at least 6 hours of direct sunlight per day.
7. Watering:
Keep the soil consistently moist until the catnip seeds germinate. Once the plants are established, they are relatively drought-tolerant.
8. Transplanting:
If starting indoors, transplant the catnip seedlings into larger pots or directly into the garden once they have a few sets of true leaves.
9. Space Plants:
Space catnip plants about 18 to 24 inches apart to allow for their spreading growth habit.
10. Fertilization:
Catnip doesn't require heavy fertilization. A balanced, all-purpose fertilizer applied at planting time is usually sufficient.
11. Pruning:
Pinch back the tops of the catnip plants to encourage bushier growth.
Harvesting the leaves periodically can also promote new growth.
12. Companion Planting:
Catnip is known to repel certain pests, making it a beneficial companion plant in the garden.
13. Catnip for Cats:
If you're growing catnip for your feline friends, keep in mind that the aromatic oils that attract cats are most concentrated in the leaves, so it's the leaves you should offer to your pets.
Growing catnip is relatively easy, and once established, it's a hardy perennial that can provide enjoyment for both cats and humans. Enjoy the process of cultivating this aromatic herb in your garden!
