Many catmint variants, including the 3-foot-tall cultivar ‘Six Hills Giant’ (Nepeta x ‘Six Hills Giant’) and compact varieties like ‘Blue Dwarf’ (Nepeta x ‘Blue Dwarf’), are planted in gardens for their delicate blue blooms and fragrant foliage. Catmint can be found growing in zones 3a to 8a of the U.S. Department of Agriculture’s plant hardiness chart, where it is utilized as a low-maintenance perennial in water-conserving landscaping.
In order to remove their late season growth, which is frequently coarse and weedy appearing, catmint needs to be severely pruned in late autumn or early winter. It’s a quick and simple process that will keep your yard neat and clean throughout the winter while also removing hiding places for garden pests.
Is catmint perennially green?
Basic catmint maintenance is simple. Catmint plants need constant watering until they get established. Mulch will aid in moisture retention and control weed growth. Pinch back plants after they reach a height of a few inches (8 cm) to encourage bushier growth.
Throughout the summer and fall, catmint blooms. Deadheading faded blossoms encourages new blossoming. It may also assist in avoiding reseeding. However, Nepeta x faassenii, often known as Faassen’s catmint, does not require deadheading because it is sterile. In the fall or after harvest, shear the plants back to half their original size.
What are some wintertime uses for catmint?
- ‘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.
- Catmint varieties can grow to be quite huge. 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 a strong root system and a number of new shoots. 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!
Should catmint be pruned in the autumn?
Catmint and I have a love-hate relationship. If you have a LOT of space for it to take over, it’s a terrific plant for providing cold tones to a space. Fortunately, catmint can be severely trimmed at any time of the year.
You can trim these back in the fall to just a few inches above the ground, but your garden will have a hole in it until they grow back flush in the spring.
If catmint is the cornerstone of your perennial border, regular summers pruning should be combined with more restrained trims of around half the plant’s height during the fall.
Does catmint survive the winter?
This perennial flower that thrives in cool climates often features blue trumpet-shaped flower clusters and grey-green leaves with a distinctive mint scent. Even though it’s frequently called catnip, cats don’t find it to be as alluring as the real stuff. However, I’ve seen that if given the chance, our cat will indulge herself. Although the plant can reach a height of 3 feet, it frequently sprawls, creating a grey-green ground cover. In the late spring and early summer, it blooms profusely. In hot temperatures in the middle of the summer, it frequently temporarily stops flowering before starting up again in the early fall, especially if the plant is vigorously trimmed down. Catmint blooms are beloved by butterflies, hummingbirds, and other useful insects.
In our location, catmint is resilient, though certain types may require winter protection in colder climates. Despite the fact that it may be grown from seed, it is considerably simpler to buy plants from a nearby nursery or get divisions from a friend’s garden in the early spring when it first begins to grow. From early spring through early fall, sow. It is simple to divide catmint. Catmint should be planted in full or partial sun in humus-rich, compost-added soil that is well-drained. Plant where it will receive afternoon shade if you’re growing in one of our region’s warmer areas. In the garden, space plants 1 to 2 feet apart.
Water newly planted plants well. They may be resistant of drought once they have grown. To help keep weeds at bay and the soil continuously moist, mulch with bark and spread compost around the base of plants in the spring.
If you aggressively deadhead flowers and prune the plant back by two-thirds after each flush of blooms, you may keep catmint in practically constant bloom from late spring until fall. After a few years, springtime division of the plant will encourage renewed development and result in the production of more plants for friends and other plantings. Catmint doesn’t self-sow because it has few pests and sterile seeds.
The traditional cottage garden plant catmint frequently grows with peonies, roses, coreopsis, and delphiniums. It’s a fantastic filler plant to add color and green foliage between later blooming flowers because of its spreading tendency. It thrives when planted in rock gardens next to walls so that it can cascade over them. It can look a little rangy, so it’s not the best option for more formal settings.
With blue-violet flowers and a neater appearance than other types since it doesn’t spread as much, Walker’s Low is a more recent variation.
White Wonder and “Snowflake” are rare white blooming plants that only reach a height of one foot.
The enormous plant and bright blue flowers of Six Hills Giant are well recognized.
Dark blue flowers on 1 to 2 foot tall stems are produced by Blue Wonder.
Should I reduce catmint throughout the winter?
In many places, catmint dies back with the frost, and the dead growth needs to be removed in order to make room for the spring’s new, fresh foliage. Depending on the climate where you are, there are different times to do this. It is preferable to wait until the spring thaw to prune catmint in regions with long, hard winters since the dead growth can act as insulation from the cold.
When a plant has gone dormant or has died back due to the cold in a milder region, it is recommended to cut the entire plant back in the fall. Because division will occur with the winter pruning, keep an eye out during the growth season for indications that the plant needs to be divided, such as less blooming.
Use precise pruning shears to cut the entire plant back to the ground, then get rid of the stems. Using a sharp spade, divide the root ball into numerous pieces, each with an equal number of roots and stems, if the plant has to be divided. Place the divisions in a bed with wet, quick-draining soil that is sunny or lightly shaded. Larger catmint kinds, like Six Hills Giant (Nepeta x “Six Hills Giant”), should be planted 3 feet apart, while more common varieties should be planted 1 1/2 to 2 feet apart.
Is perennial catmint a hardy plant?
Nepeta, often known as catmint, is a popular blooming perennial that is attractive, resilient, and simple to grow. It gets its name from the scented foliage that attracts cats. Green or grey-green aromatic leaves cover its stems from summer to autumn, along with tiny mauve or blue two-lipped blooms.
Catmint leaves, stems, and blossoms can be safely nibbled and consumed by cats.
In fact, dried catmint leaves are frequently used as filler in cat toys. Some felines adore it so much that they roll around and rest on the vegetation.
The term “catmint” refers to a variety of Nepeta species and variants, all of which are native to nations in the Northern Hemisphere. Despite being the most scented variety of catmint, Nepeta cataria, also known as “catnip,” is not as beautiful as other variants. Bees and other helpful pollinating insects find catmint to be particularly alluring.
How does catnip fare over the winter?
The Plant Catnip Is a Perennial If left unchecked, the plant can reach a height of two to three feet and spreads quickly. Catnip plants in colder climates wither in the winter and reappear in the spring.
Catnip will it survive the winter?
Your cats should be able to roll around and rub on the catnip without damaging nearby plants, so plant it there. Some cats enjoy catnip so much that they will roll, lay, and even nibble it to death.
If you discover that to be the case, insert some thin dowels or bamboo poles every 2 to 3 inches wherever you are growing catnip to prevent cats from lying on top of the plant. Catnip is a low, loosely branched perennial plant, which means that it will typically wither away in the winter and reappear in the spring. Catnip can be positioned in front of purple coneflower, which blooms at the same time, in a flowerbed. The plant produces inconspicuous, small, white blossoms. It may also be cultivated in containers. Grow numerous pots for indoor cats that you may alternate between the indoors and the outside. Since catnip needs a lot of light to grow, you’ll need to bring in fresh indoor pots every few weeks and move the old ones back outside. In order to draw your cat and reduce the rodent population, you might also want to grow catnip close to your vegetable garden.
When should plants be pruned back during the winter?
When in the fall is the greatest time to cut back? A: “Before the fresh new growth starts and when they start to look too ratty for you,” according to Sarah. Wait until after the plants have had multiple hard frosts to prune frost-sensitive plants to be sure they are dormant.
Should I prune my perennials to prepare for winter?
Warm-weather gardeners can use the fall and occasionally even the winter as additional growing seasons. However, October is a perfect time to start garden cleanup if you live somewhere with harsh winters. The phrase “four seasons of interest in the garden” is often used, yet perennial plants hardly ever fall within this description. The majority of perennials lose their beauty as the weather becomes colder, and any plant that is sick, infested, or otherwise unhealthy should be trimmed back and removed rather than let to survive the winter.
But if perennials are cut too late in the growing season, some of them just don’t do well. They depend on their fallen leaves’ wintertime protection to help them live. It is advisable to prune these 43 plants in the spring.
Tip
Even if the plant would ordinarily benefit from being left standing during the winter, it is recommended to trim away and discard the afflicted foliage when plants have obvious signs of bacterial or fungal disease. You don’t want diseased plants to remain over winter since the microbes can spread and infect other plants. The same is true with sick leaves and other ground-covering debris. For those plants that benefit from winter protection, remove this material and cover the area with a fresh, sterile mulch.
Does catmint withstand frost?
Catnip cold tolerance is pretty high and it grows well in zones 3 to 9. However, growing catnip outside can be problematic in particularly cold winters or in colder areas. It might be important to offer catnip plants some protection and additional care throughout the winter if you want them to return healthy and productively each spring. This is crucial if you reside in the cooler, northern regions of its growing region.
How can I get catmint ready for the winter?
Pruning catmint in the winter or late autumn offers many advantages. It will prevent catmint from toppling over onto nearby plants, eliminate areas where pests can overwinter, and maintain the garden bed’s orderly appearance until the arrival of new growth in the spring. The plant should be fully dormant at this point, which usually occurs after many harsh frosts have been applied to it. Catmint is not one of the many perennials whose seedpods serve as food for wildlife. According to the University of Vermont Department of Plant and Soil Science, since the seeds are useless to birds, the entire plant can be severely pruned.
For the winter months, the University of Maryland Cooperative Extension Service advises trimming perennials like catmint back to a height of 2 to 4 inches. Use strong pruning shears or hedge trimmers to remove the entire plant by cutting across it. When removing the stems, don’t worry about being careful; catmint tolerates vigorous handling. Instead of composting them, put all dead stems and seed pods in a green waste container. The plants’ surrounding dead, falling leaves and seed pods should also be raked up and thrown away.
