Catmints also produce gray-green foliage, and their flower spikes make them particularly attractive to pollinators like bees, hummingbirds, and butterflies.

Additionally, they are deer and rabbit-resistant, though may occasionally attract aphids.

Their varieties, like the popular ‘Walker’s Low’, form mounds of color, with flowers ranging from pink to yellow. The bloom is long-lasting, making them a prime choice for gardeners looking for plants that can draw in pollinators over an extended period.

Bear in mind that, though they are part of the mint family, Catmints are more compact and sturdy in stem and structure, making them more resistant to pests and more forgiving of tough weather and soil conditions than many of their mint cousins.

Catmint will bloom from midsummer well into the fall, attracting numerous pollinators to your garden. You’ll find spikes of yellow and pink flowers appearing among the lavender-blue, beckoning bees and butterflies.

To encourage future generations of catmint and a continual appearance of these flowers, allow some of the seeds to fall to ground.


Catmint plants thrive in diverse sunlight conditions. Ideally, they flourish under full sun where they can receive six hours or more of direct sunlight daily.

However, they also adapt well to partial shade, most especially benefitting from afternoon shade in hotter climates. It is noteworthy to mention that, though these plants are rather tolerant, their bloom may be slightly less abundant in less sunny locales.

Regardless, in harmoniously balancing their sun exposure, catmint plants will present you with an enchanting display of lavender-blue flowers from late spring to midsummer.

While catmint plants exhibit hardy characteristics and can thrive in a broad array of environments, they prefer well-draining soil.

This drought-tolerant member of the mint family will flourish best when its roots can expand freely, safe from stagnating moisture. Adding compost to the soil will deliver necessary nutrients and improve drainage, promoting healthier and more vibrant plants.

Approximately 4 weeks after planting, it can also benefit from a balanced slow-release fertilizer, which continues to provide essential nutrients throughout the first growing season.

Despite these preferences, catmint plants are highly adaptable and can still grow in less-than-optimal soil conditions if required.


Catmint plants hail from regions of Africa and Asia known for dry climate. As such, they are naturally drought-tolerant.

During their first growing season, these hardy perennials require regular watering to establish a robust root system. However, once established, a sporadic watering schedule suffices, especially if planted in well-draining soil.

Intense afternoon shade can cause the soil to retain more moisture, reducing the plant’s watering needs even further.

Regularity of water is paramount during particularly dry spells, yet overwatering can lead to problems with aphids or could potentially rot the root and stem.

Temperature and Humidity

Catmint plants are robust perennials that can adapt effectively to various climate conditions, from hot Africa summers to the cooler, temperamental climate of Asia.

The plants require full sun exposure for optimal growth but can endure partial shade, especially in the hot afternoon, preserving their gray-green foliage from yellowing under harsh sunlight.

They thrive in an environment with well-draining soil and moderate humidity. Moreover, Catmint plants are drought tolerant, proving hardy even in arid conditions once established after their first growing season.

Too much humidity, however, might attract pests like aphids, so ensure your catmint has good air circulation, particularly in more humid climates.


Catmint plants are considered hardy and adaptable, requiring minimal attention in terms of fertilizer. During the first growing season, a light application of slow-release granular fertilizer mixed with compost can benefit new plants.

Applying it in late spring, just before the onset of the bloom period, can promote robust growth and abundant lavender-blue flowers. However, supplementing with fertilizer is not commonly required in subsequent years if plants are growing in well-draining soil enriched with compost.

Over-fertilization, especially with nitrogen-rich varieties, can lead to excessive foliage growth at the expense of flower production. Therefore, maintaining a balance is crucial for these plants.


Pruning catmint plants isn’t a complicated task, with these hardy perennials requiring just a modest trim.

For optimal bloom, it’s best to prune after their first flush of lavender-blue flowers in late spring. This triggers a growth rejuvenating process in the stem, allowing for new plants and a second, more robust bloom in the midsummer.

Once the plant has finished blooming entirely, cut back the gray-green foliage by around a third. This will encourage the plant to form compact, neat mounds, a characteristic trait of the Walker’s Low variety, and keep your herb garden looking tidy.

The removed plant parts can be added to your compost pile, contributing to a healthy, well-drained soil in your garden.

Catmint plants are perennials that excel in various climates. In many regions, they can handle cold winters with little care, thanks to their gray-green foliage that can endure colder temperatures.

Nevertheless, to promote healthy growth for the following year, cut back the stems of catmint to the ground in late fall or early winter.

If the winter climate is harsh, covering the cut-down mounds with a layer of compost or mulch could be beneficial as it adds extra protection.

Remember that they appreciate well-draining soil, so avoid waterlogged conditions for a warmer overwintering environment. Despite these provisions, the new plants grown in the first growing season, particularly late in the year, might require extra protection through the coldest months.

Catmint vs Catnip

Catnip (Nepeta cataria) is a type of catmint that is probably the most well-known species in the Nepeta genus, at least among home gardeners. It isn’t the only kind of catmint that makes cats loopy, but it’s your best bet if that’s your aim.

Step 3: Caring for Catmint

Proper care starts from the first growing season. Regular watering is essential in this period until the plants are well-established. Despite being drought tolerant, new plants benefit from consistent moisture.

Applying a slow-release fertilizer midsummer can encourage a second bloom. Be on the lookout for aphids, which can occasionally infest the stem and lower side of the leaves. These insects are easily managed with organic insecticides.

Step 4: Managing Growth and Propagation

As your plants mature, they will naturally produce stems with spikes of yellow, pink, or lavender-blue flowers from midsummer to early fall, attracting an array of bees, butterflies, and even hummingbirds.

For an even fuller bloom next season, cut back the flower spikes once the first flush of bloom is over. Propagate new plants by division every 3-4 years in early spring.

Despite their alluring flowers and aromatic leaves, these perennials are pleasingly resistant to rabbits.

How to Pot or Repot Catmint

Step 1: Preparing the Soil and Pot

The key to growing successful Catmint plants is well-draining soil. This hardy perennial does not like standing water, and will easily adapt to varying soil conditions, provided they don’t get too bogged down.

If you are working with heavy clay soils, consider improving its drainage capabilities by adding organic matter or compost.

When you’re ready to pot your new plants, create a blend of garden soil and compost in the pot. Carefully remove the Catmint from its original container, keeping as much soil around the roots as possible, and transfer it into its new pot.

Fill in around the plant with your soil mix until it’s level with the top of the pot, lightly pressing the soil down for stability.

While catmint plants are generally known to be deer-resistant, the aromatic gray-green foliage and lavender-blue flowers of the plant can appeal to rabbits. Latex fencing or planting catmint close to walkways or human-activity areas can deter these pests. Gardeners also report that Walker’s Low and other similar varieties of catmint are more resistant to rabbit damage compared to others.

Fungal Diseases

Due to its member of the mint family (Lamiaceae) roots, catmint can be susceptible to some common mint family diseases including downy mildew and verticillium wilt.

Both diseases can cause yellowing and wilting of leaves and, in severe cases, may lead to plant death. Ensuring your soil is well-draining and your plants aren’t overcrowded can help prevent these diseases.

Additionally, compost and organic fertilizers can also strengthen your plants’ resistance to disease during their first growing season and beyond.

Common Plant Problems and Solutions for Catmint

Brown Tips on Leaves

When you notice brown tips on your catmint plants’ gray-green foliage, it’s likely the result of too much direct sunlight. These perennials, originally from Asia and a member of the Lamiaceae or mint family, thrive in full sun to partial shade.

However, prolonged exposure to intense sunlight can scorch them, causing the tell-tale brown tips. To counter this, ensure you plant them where they can enjoy afternoon shade and protection from extreme heat.

Yellowing Leaves

If your catmint exhibits yellow leaves, odds are it’s dealing with poor drainage. As a species in the Nepeta genus, it requires well-draining soil to maintain its overall health.

Sitting in waterlogged soil can lead to root rot, a disease best avoided in your herb garden. To resolve this, make sure to amend your soil with organic compost or fertilize it with a well-balanced fertilizer to enhance its drainage capacity.

Inadequate Blooming

Late spring till midsummer is the typical blooming season for many varieties of catmint, with spikes of blue, pink, and yellow flowers that draw pollinators en masse.

If your catmint fails to bloom satisfactorily, it might be due to a mismatch between the plant’s climate needs and its environment. While the plant favors full sun, remember that it must be coupled with the plant being drought tolerant – meaning excessive watering could dampen its blooming prowess.

Matching the hardy catmint with the right climate requirements and well-draining soil will sort this issue out. It’s well worth the effort, as this deer-resistant and rabbit-resistant plant can beautify your walkways and garden mounds spectacularly when in full bloom!
