Catmint Herb: How To Grow Catmint

Catmint is an aromatic herb that is commonly grown in the garden. It produces clusters of lavender-blue flowers amid mounds of gray-green foliage. This easily grown plant has an interesting history regarding its various uses in the landscape. For example, the herb is thought to have been first cultivated in the Roman town of Nepeti, where it was used as herbal tea [1] and insect repellent. This is also believed to be the origin of its genus name, Nepeta.

Difference Between Catnip and Catmint

Many people wonder what is the difference between catnip and catmint. While basically considered the same plant that shares many of the same characteristics, there are differences between the two species. Catnip [2] (Nepeta cataria) has less ornamental value in the garden than its catmint (Nepeta mussinii) counterpart.

Catnip is also found to be highly attractive to cats, with many of them exhibiting a naturally induced euphoria around the plant. They may nibble on it or even roll around in the foliage. This type is most suitable for “cat friendly” gardens. If you don’t want your garden overrun with felines, plant catmint instead, which is much less attractive to them.

How to Grow Catmint

Catmint herb is easy to grow. These plants are good for mass planting or edging and are suitable near vegetables as an insect deterrent—especially aphids [3] and Japanese beetles [4].

Catmint can be grown in sun or partial shade with average, well-draining soil. They are even heat and drought tolerant, making them excellent plants for dry garden areas. Catmint is most often grown by seed or through division.

How & When to Plant Catmint

The seeds or divisions [5] of catmint plant are planted in spring. They require plenty of space too and should be spaced (or thinned) to at least a foot or so apart. Overcrowded plants can lead to powdery mildew [6] or leaf spot, especially in hot, humid climates.

Caution is needed when planting some types of catmint plants, as they can be aggressive growers. Therefore, you may want to add some edging around them. Likewise, catmint can be planted and grown in containers [7].

Care of Catmint

Basic care of catmint is easy. Water catmint plants regularly until they become well established. Mulch [8] will help retain moisture and keep down weeds. Once plants are a few inches tall, pinch them back to promote bushier growth.

Catmint blooms throughout summer and fall. Deadheading spent blooms [9] promotes additional flowering. It can also help prevent reseeding. Faassen’s catmint (Nepeta x faassenii) is sterile however, and doesn’t require deadheading. Shear the plants back to half their size in fall or following harvest.

Harvesting and Uses of Catmint Herb

Catmint can be used fresh, dried [10], or frozen [11] for both culinary and herbal use. Harvest leaves [12] as flowers begin to bloom, cutting top leaves, stems, and flowers if desired. Spread out to dry in a cool, ventilated area and store the dried herb in an airtight container or bag to preserve its potency.

The leaves and shoots can be added to soups and sauces. Tea made from the leaves and flowers can be used for calming nerves and relieving coughs, congestion, and menstrual cramps.
