In the world of gardening, few plants offer the same blend of beauty, resilience, and versatility as Walker’s Low Catmint (Nepeta racemosa ‘Walker’s Low’). This perennial favorite is celebrated for its aromatic foliage, stunning lavender-blue flowers, and ability to thrive in a variety of conditions. Whether you’re a seasoned gardener or a novice, Walker’s Low Catmint is a plant that rewards minimal effort with maximum impact. Below, we’ll explore easy care tips to ensure your catmint flourishes year after year.
1. Choosing the Right Location
Sunlight and soil are the cornerstones of catmint’s success.
Walker’s Low Catmint thrives in full sun, requiring at least 6 hours of direct sunlight daily. While it can tolerate partial shade, especially in hotter climates, too much shade may reduce flowering and cause the plant to sprawl. When it comes to soil, catmint prefers well-draining conditions. It’s remarkably tolerant of poor soils, including rocky or sandy terrain, but waterlogged soil can lead to root rot.
Pro Tip: If your garden has heavy clay soil, amend it with organic matter like compost or sand to improve drainage.
2. Watering Wisely
Pro: Catmint is drought-tolerant once established.
Con: Overwatering can cause root issues.
Newly planted catmint requires regular watering to establish its root system. Once established, it’s remarkably drought-resistant, needing water only during prolonged dry spells. A good rule of thumb is to water deeply once a week, ensuring the soil dries out between waterings. Avoid shallow, frequent watering, as this encourages surface roots and weakens the plant.
3. Pruning for Vigor and Bloom
Step 1: Shear back by one-third in early spring to encourage compact growth.
Step 2: Deadhead spent flowers throughout the summer to promote continuous blooming.
Step 3: In late summer, cut back the entire plant by half to rejuvenate growth and prevent legginess.
Pruning is essential to keep Walker’s Low Catmint looking its best. Regular deadheading not only extends the flowering period but also prevents self-seeding, which can lead to unwanted spread. A hard prune in late summer can also help prevent the plant from becoming woody and unkempt.
4. Fertilizing Sparingly
Less is more when it comes to feeding catmint.
Walker’s Low Catmint is not a heavy feeder and can thrive without fertilizer in nutrient-rich soils. If your soil is poor, apply a balanced, slow-release fertilizer in spring at half the recommended rate. Over-fertilizing can lead to excessive foliage growth at the expense of flowers and may weaken the plant’s natural hardiness.
5. Managing Pests and Diseases
Catmint is virtually pest-free, but watch out for aphids and spider mites in dry conditions.
One of the greatest advantages of Walker’s Low Catmint is its resistance to pests and diseases. However, in stressed or overcrowded conditions, it may attract aphids or spider mites. Regularly inspect the plant and treat infestations with insecticidal soap or neem oil. Proper spacing and airflow around the plant can prevent most issues.
6. Overwintering and Spring Care
Catmint is hardy but benefits from a little winter protection.
Walker’s Low Catmint is hardy in USDA zones 4-8, meaning it can withstand cold temperatures. However, in regions with harsh winters, apply a light layer of mulch around the base of the plant to protect the roots. Remove the mulch in early spring and prune the plant to encourage new growth.
7. Propagation and Division
Step 1: Divide mature clumps every 3-4 years in spring or fall.
Step 2: Replant divisions in well-draining soil.
Step 3: Water regularly until new plants are established.
Over time, Walker’s Low Catmint may become overcrowded or less vigorous. Dividing the plant not only rejuvenates it but also provides new plants for other areas of your garden. Simply dig up the clump, separate it into smaller sections with a sharp spade, and replant them at the same depth as the original.
8. Companion Planting Ideas
Catmint pairs beautifully with a variety of plants.
Its silvery-green foliage and soft blue flowers make Walker’s Low Catmint an excellent companion for roses, salvias, and ornamental grasses. It also works well in pollinator gardens, attracting bees, butterflies, and hummingbirds. For a striking contrast, plant it alongside black-eyed Susans or purple coneflowers.
Fun Fact: Cats are naturally drawn to catmint, so consider planting it away from areas where you want to keep feline visitors at bay.
