These drought-tolerant plants are ideal for borders, rock gardens, and pots and have fragrant blossoms that draw butterflies and bees. Catmint has plants that are 1 to 3 feet tall and wide, and it blooms from early summer to early fall. Look into other perennial blooms to draw pollinators.
Is a lot of water required for catmint?
The initial week of growth requires frequent watering every couple of days, followed by one inch of water every week for at least another month if there is no rain. Catmints are drought-tolerant once rooted and don’t require watering.
How frequently should catmint be watered?
Members of the mint family known as Nepeta catmints (Nepata spp.) have spectacular spikes of small purple, blue, pink, yellow, or white flowers that bloom in late spring or early summer. Additionally, the plant produces attractive, soft, aromatic, grayish-green foliage that is present for the entire growing season. Versatile catmints can be used almost everywhere in your landscaping, including rock gardens, bird, herb, and butterfly gardens. For informal environments, taller plants produce attractive hedges, while low-growing types provide aromatic ground coverings. The majority of catmint species survive in zones 3 through 8 of the U.S. Department of Agriculture’s plant hardiness scale and are perennials that require minimal maintenance.
Pick a planting location with ordinary soils that are dry to mediumly moist and have good drainage. Nepeta catmints prefer areas with full sun, although they also benefit from some afternoon shade.
Use a garden fork to loosen the soil to a depth of about one foot before preparing the planting area. Before sowing catmint seeds, work a 3-inch layer of organic mulch or compost into the churned soil.
Catmint seeds should be sown in the fall, with plants being spaced 18 to 30 inches apart to accommodate the plants’ renownedly quick growth and spread. After planting, immediately water the area well to let the soil settle around the seeds.
During its initial growing season, give newly planted catmint around 1 inch of water per week. These drought-tolerant plants only require watering around once every three weeks once they are established. Water the soil just enough to keep the roots moist, but don’t water it too much because this plant detests having damp feet.
Every spring or fall, cover catmint plants with a 1- to 2-inch layer of compost or organic mulch. This gives plants the nutrition they need to be healthy the following year while keeping the roots cool, retaining soil moisture, and thwarting weed growth.
After the initial flowering time, use hand shears to prune flower spikes and stems by around one-third in order to encourage a second late-summer bloom. To prevent the plants from growing too tall or lanky, prune catmint plants to the ground in the spring.
How many sun-filled hours does catmint require?
- ‘Walker’s Low’ plants are 30 inches tall and 36 inches wide, with lavender-blue flowers. As a side note, the name is not short because it derives from an Irish garden. It is actually almost as tall as the “Six Hills Giant.” Walker’s Low was chosen by the Perennial Plant Association as their Perennial of the Year for 2007.
Don’t restrict yourself to just these four options if you feel driven to hunt for catmint in your neighborhood garden centers. Numerous other top-notch cultivars are also readily available, including “Dropmore,” “Blue Wonder,” and “Junior Walker,” a scaled-down variety of “Walker’s Low” that stands 16 inches tall.
- Catmint tends to grow wider than tall, so give it lots of room.
- Even while catmint likes direct sunlight, it can also tolerate moderate afternoon shadow.
- Water new plants or transplants until they can survive on their own. Following that, established plants can withstand heat and drought.
- Never fertilize it again. Catmint prefers well-drained, somewhat fertile soil. In fact, a plant may flip over or split in half if the soil is excessively rich. In that case, trim the plant back to make it look neat. Compost added in the spring or fall will provide the plant the nutrients it needs to thrive.
- After the first blooming flush of the plants has finished, shear them back by a third or more. The plants will be more orderly, their size will be limited, and this will encourage a second rush of blossoms later in the summer. The plant will still bloom often and maintain its lovely appearance during the stifling summer months even without being sheared.
- Over the winter, keep any dead foliage in place to help protect the crown. Wait till the beginning of spring to trim it.
- Divide catmint every three to four years, preferably in the spring or early fall, to maintain it healthy. During the first growing season, until the plants take root, keep it well-watered.
- Some cultivars of catmint can grow extremely large. Pinch the plant back in the spring after it has grown a few inches tall to encourage a bushier growth habit if you wish to limit the plant’s total size.
- Cut a vertical chunk off of an established clump of catmint in the spring to reproduce it. Make sure the division has multiple young shoots and a significant root system. Till the plant takes root, keep it well-watered.
- Cuttings can also be used to spread catmint. Before flower buds grow in the spring, clip healthy shoots at a length of three inches. The cuttings should be placed in a moist medium, such as sand or a peat-perlite mixture. Within two to three weeks, they should start to root.
- Catmint is typically unaffected by either pests or illnesses. The only issue that can occasionally arise is leaf spot. There is no consensus that the severity of this fungus illness justifies control measures.
- Experience has taught me that some cats are drawn to catmint. If you’re worried about this, cover newly planted or transplanted catmint with chicken wire to stop your cat from consuming it or rolling about in it.
- This plant attracts butterflies and bees like crazy. Additionally, hummingbirds adore it.
- You’ll adore this plant if your garden is plagued by four-legged animals other than cats. Deer, voles, and rabbits are deterred by the foliage’s minty aroma. THIS is a plant that pays for itself, at last!
Does catmint have a sun limit?
The herb catmint is simple to grow. These plants are appropriate for bulk planting or edging, and they can be used as an insect deterrent close to vegetables, particularly for aphids and Japanese beetles.
Catmint can be grown in normal, well-draining soil in the sun or light shade. They are good plants for dry garden regions since they can withstand both heat and drought. The two main ways to cultivate catmint are from seed or through division.
Where to plant:
Although they will tolerate some afternoon shadow, most plants prefer full sun, especially when grown in warm areas. Catmint may thrive in almost any well-drained soil type. Root rot can develop on wet or rainy grounds.
How to plant:
Although it is possible to grow plants from seed, buying nursery-grown plants is simpler and more dependable because hybrids may not grow true to seed and certain kinds are sterile. Since many plants have a tendency to grow wider than tall, leave plenty of space between them.
Is cat mint a problem?
They believed it would entice cats to prey on rodents hiding about the farm or house. However, current research suggests that catmint may not just be discovered around the foundations of historic European homes and barns. According to a recent USDA study, termites are unlikely to dig tunnels through soil where catmint flourishes. Naturally, a moat made of this plant would prevent these pests from penetrating the wood of a hut or cottage.
Termites, mosquitoes, and cockroaches are all repelled by the same chemical that draws cats. Nepeta cataria, also referred to as common catnip, is a plant that contains it. Nepetalactone, a terpene found in these herbs, has been shown to be several times more effective at repelling insects than harmful DEET. To influence a cat, the plants release oils that must be breathed rather than consumed. This explains why cats are so prone to rolling around in catmint plants. More volatile oils are released from the leaves when it is bruised. Cats can detect airborne odors down to one part per billion.
Not all felines react the same way to these herbs. In fact, roughly 30% of household cats might not even respond to catmint. It’s a hereditary reaction that can vary in intensity from person to person and is inherited. Strangely, until they are at least 3 months old, extremely young kittens rarely react to nepetalactone.
There are a dizzying variety of plants in the genus Nepeta. The large invasive plant known as real catmint is described above. It grows to a height of three feet and bears few white blooms. It usually only appears in herb gardens and has very nothing to recommend it in terms of aesthetics. Due to its hardiness up to Zone 3, it is a fantastic choice for gardens in the north.
Through natural cross-pollination and human breeding, numerous species have been introduced into gardens over time and transformed into new varieties. The outcome is a wide variety of garden-worthy catmints that are much better prospects for your yard than the usual kind. Keep in mind that these immigrants won’t be as resistant to the cold as the species is. The majority, but not all, are sterile, preventing plants from spreading outward in the absence of viable seed. Simply deadhead the flowers after they are spent to stop seed formation in order to completely avoid self sowing.
The Six Hills Giant, which stands 3 feet tall, is the most impressive version. Late in the summer, foot-long spikes of dark violet blooms appear on lush, spherical plants. It is generally accessible and a superb option for novice growers.
Nepeta racemosa “Walker’s Low,” which has a shorter size, is an excellent edging plant. A gentle carpet of blue fills up the front of a border. It only grows to a height of 18 inches but produces dense clusters of vividly blue flower spikes. Walkers Low and Six Hills are resilient to Zone 5.
Catmints typically grow best in sandy, well-drained soils, although they will grow almost anywhere that isn’t moist. Late in the growing season, they can become rangy, and regular trimming is beneficial to prevent the taller forms from flopping in the rain.
Today, catmint merits another look as a natural pest deterrent for eco-friendly dwellings. wherever there is a chance of infestation, plant. Kittie won’t overdose, though, as cats all seem to have a sense of proportion.
What vegetation thrives in catmint?
Consider growing verbena, agastache, lavender, and tufted hairgrass alongside catmint as companion plants.
The blue catmint blossoms go perfectly with other perennials with the same growing conditions, like:
- Sage of Europe/Southernwood
- Salvia.
- The beard of Jupiter
- Yarrow.
- Pig’s Ear.
- Winecups and Poppy Mallow.
Drainage problems
If the catmint plant has poor drainage, the leaves frequently turn yellow. This is frequently seen when there is a lot of rain or when you overwater the plants. Make sure the plants are securely planted and have not been loosened by water.
Young catmint leaves may turn yellow if they receive too much or too little water. If the earth feels dry, check to see if the plants need watering.
Nutrient deficiency
A nitrogen shortage could also cause the catmint leaves to turn yellow. Nitrogen, magnesium, and potassium are nutrients that are crucial to plants. The plants won’t thrive and their leaves may become yellow and withered if the soil lacks any of these nutrients. To enrich the soil and promote the healthful growth of the plants, add fertilizers that offer these nutrients.
To check the soil, you should ideally also utilize a soil test kit. To stop the leaves from getting any more yellow, amend the soil and provide the appropriate nutrients based on the results of the soil test.
Transplant shock
Transplant shock may occur when catmint plants are relocated from their original environment to a new one. Yellowing leaves may be a consequence of the sudden shift in weather. While transplanting during the growing season can lessen this circumstance, transplant shock is still a possibility. For a week to ten days, keep an eye on the transplanted plants to observe whether the color of the leaves changes.
Stress
Catmint leaves may become yellow if they are under stress from their surroundings. Strong winds, an excessive amount of sun, or both are examples of this. Since they could not be suitable for that specific area or soil, the location where you put your plants could also be a contributing factor. If so, moving the plants to a location or type of soil where they will thrive is necessary.
Make sure your plants have shade during the warmest part of the day to protect them from too much sun. Place your plants indoors or in a greenhouse to protect them if there are heavy winds predicted in your area.
From Seed
Four to eight weeks prior to the last frost date, seeds can be started inside. Seeds should be barely covered in potting mix when placed in three- or four-inch pots.
Maintain moisture for two to three weeks until seedlings appear, and then place the pots in bright light until they have at least two sets of genuine leaves.
Additionally, you can directly plant seeds outside before the first fall frost or in the spring following the last frost.
By chilling stratifying seeds in the freezer for a whole night and then soaking them in water for 12 to 24 hours before planting, you can increase germination.
Garden soil and an inch of organic matter should be prepared for a garden bed or container. Since light promotes germination in these plants, scatter the seeds on top, just covering them.
For two to three weeks, until sprouts grow, lightly water the plant and keep moist. Seedlings should be spaced around 18 inches apart.
Not all nepeta species can be started from seed, which should be noted. Some plants, like Faassen’s catmint, can only be multiplied through division or from cuttings since they are sterile. Fortunately, doing this is simple.
By Division
Although it’s ideal to avoid dividing plants in the heat of the summer, if you have established plants available, divisions are likely the simplest and fastest technique of propagating new plants. These can be taken at any time during the growth season.
Locate a portion of an established plant with a strong, mature root system, cut it off from the rest of the plant using a garden spade, and carefully dig it up.
The entire plant can alternatively be dug up, divided into pieces, and then each piece is planted separately in the garden or in a container.
