Catmint

Nepeta × faassenii 'Walker's Low', commonly known as Catmint, is a delightful herbaceous perennial plant that produces abundant blue-violet flowers and aromatic foliage.

To ensure the health and beauty of this plant throughout the year, it's important to provide seasonal care tailored to its specific needs. This guide explains how to care for Nepeta × faassenii 'Walker's Low' across all seasons.

Spring

Pruning and Maintenance

In early spring, inspect your catmint for any dead or damaged stems and foliage, and prune these back using clean, sharp secateurs to encourage healthy new growth. 

In late spring, cut the plant back again to promote a second, more compact flush of flowers. You can also prune to shape the plant and encourage a bushier habit, cutting it back by around a third will help maintain a neat, compact appearance.

Feed

Apply a balanced, slow-release fertiliser formulated for flowering perennials in spring as new growth emerges. Follow the manufacturer's instructions for the recommended dosage to support healthy development.

Dividing (if necessary)

Every 2-3 years, divide large clumps of Catmint to rejuvenate the plant. Lift the clump, divide it into smaller sections, and replant them into well prepared soil with adequate spacing.

.

Gradually increase watering as the weather warms up. Keep the soil consistently moist but not waterlogged.

Summer

Mulching

Apply a 2 to 3-inch layer of organic mulch around the base of the plant to retain soil moisture, regulate temperature and suppress weeds. This is especially important in hot and dry summer conditions.

Watering

Catmint is drought-tolerant but benefits from regular watering during dry spells, especially for young plants to encourage deep root growth. Water deeply, allowing the soil to dry between waterings.

Autumn

Pruning and Maintenance

After the main flowering period, trim back the spent flower spikes to encourage a second flush of blooms. Lightly prune the plant to maintain its shape and remove any unruly growth.

Protection from frost

Catmint is generally hardy, but providing extra protection during harsh winters can be beneficial, especially in colder regions. Applying a layer of mulch around the base of the plant helps insulate the roots.

Winter

Pest and disease prevention

Pests and diseases are less active in winter, but it's essential to inspect your Catmint for any signs of issues and address them promptly.
