Catmint is a hardy perennial known for its soft gray-green foliage and spikes of lavender-blue flowers. It thrives in full sun and well-drained soil, making it an excellent choice for borders, edging, and drought-tolerant gardens. Once established, catmint requires little water and is highly tolerant of dry conditions. It attracts bees, butterflies, and other pollinators while remaining resistant to deer and rabbits. Good air circulation helps maintain healthy foliage. Catmint has a long blooming season and can produce repeat flowers if trimmed after the first flush. With its relaxed growth habit and minimal care needs, catmint is a reliable option for adding color and texture throughout the growing season.

Catmint can be grown from seed, though germination may be improved with a short cold treatment. Sow seeds in a well-draining seed-starting mix and lightly cover them with soil. Keep the soil evenly moist and place containers in a bright location. Germination typically occurs within one to two weeks under the right conditions. Seeds can also be started indoors before the last frost or direct sown outdoors once temperatures warm. Once seedlings are established, thin or transplant them to allow proper spacing.

Plant catmint in full sun with well-drained soil. Dig a hole slightly wider than the root ball and plant at the same depth it was growing before. Water thoroughly after planting to help roots establish. Space plants about 18 to 24 inches apart to allow for spreading growth and airflow. Catmint also grows well in containers with a light, well-draining potting mix. Avoid heavy or wet soil, which can lead to root problems. Proper placement encourages compact growth and abundant blooms.

Catmint requires minimal feeding and often performs best in average soil. Adding compost at planting time can improve soil structure and provide nutrients. A light application of balanced fertilizer in spring may support early growth, but excessive feeding should be avoided. Too many nutrients can lead to floppy stems and fewer flowers. Container-grown plants may benefit from occasional light feeding. Maintaining moderate fertility supports healthy growth and long-lasting blooms without compromising the plant’s natural form.

Catmint is cold hardy and generally requires little winter care. After frost, stems can be cut back or left standing for winter interest. Applying a light mulch layer helps protect roots and regulate soil temperature in colder climates. Ensure the soil remains well drained during winter, as excess moisture can cause root issues. Remove old growth in early spring to make way for new shoots.

Catmint blooms can be cut for fresh or dried arrangements when flowers are fully open. After the first bloom, shear the plant back by about one third to encourage a second flush of flowers. Deadheading can help extend the bloom period, though it is not always necessary. In fall, cut back stems or leave them for winter texture. Dividing plants every few years helps maintain vigor. Regular pruning keeps catmint compact and encourages continuous flowering.
