Originating from Europe, Asia, and Africa, Nepeta species have a rich history as culinary herbs, ornamental plants, and herbal remedies. Introduced to North America in the 1800s, catnip (N. cataria) has been used for its medicinal properties, while other species like N. mussinii and N. x faassenii are grown for their ornamental value.

Catmint Plant Propagation

Catmint plants are easy to propagate through various methods such as seed, division, and cuttings. Here’s a quick guide on how to propagate catmint:

From Seed:

Start seeds indoors or direct sow in well-draining soil.
Lightly cover seeds and keep moist until sprouts appear.
Cold stratification and soaking can improve germination rates.

By Division:

Divide established plants during the growing season.
Replant divided sections in the garden or containers.
Water regularly until plants are established.

From Cuttings:

Growing Tips:

Space plants 18 inches apart.
Provide 1 inch of water per week initially.
Mulch around the base for improved drainage.

Pruning and Maintenance

To keep catmint plants healthy and blooming, regular pruning and maintenance are essential. Deadheading after the first bloom and trimming back foliage can promote a fuller second bloom. If plants become too invasive, dividing them each season can help manage their growth.

Species and Cultivars to Select

When choosing catmint species and cultivars for your garden, consider factors such as growth habit, flower color, and height. Here are some popular catmint varieties to consider:

Nepeta cataria: Traditional catnip with large, toothed leaves and small white, purple, or pink flowers.
Nepeta mussinii: Compact mounding ornamental with lavender blue flowers.
Nepeta x faassenii ‘Walker’s Low’: Sterile cultivar with lavender blue flowers.

Managing Pests and Disease

Catmint plants are relatively pest and disease-resistant. However, occasional visits from insects like aphids, slugs, and spider mites can occur. To manage pests, consider using insecticidal soap or handpicking. Keep an eye out for common diseases like bacterial leaf spot and blight, and remove infected foliage promptly to prevent spread.

Harvesting and Preserving Catmint

Harvest catmint leaves and flowers during midsummer when they are at their peak flavor. Harvesting can be done by cutting stems and drying the leaves for later use in teas or catnip toys. Store dried leaves and flowers in airtight containers in a dark, dry place.
