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.
How can I get catmint ready for the winter?
You can easily store catnip indoors for the winter if you grow it in a container. Give it a cooler location with moderate sunlight and sporadic contact with water. However, if your catnip is grown outdoors in beds, you need get it ready for the winter.
Trimming back your catnip in the late fall will prepare it for the winter. Just a few inches (8 cm) should be removed from the stems, and new growth should be specifically trimmed back to prevent harm from the cold. After giving the plant one last, thorough drink, don’t water it again until spring.
You can use a cloche to cover the plant to protect it from frost in areas where it gets really cold. To prevent your catnip from becoming too hot, keep an eye on it and remove or shade it on sunny, warm days.
As winter approaches, avoid fertilising your catnip plants. This will just promote new growth that might be harmed by the winter’s colder temperatures. Aim to use no more mulch than necessary. A little mulch can keep the soil warm and wet, but too much can stop the sun from warming it.
Your catnip plant should return in the spring, huge, healthy, and thriving, if you follow some safety precautions and avoid a few simple mistakes.
How much catmint do you cut back on?
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.
Should catmint be pruned in the spring or fall?
- ‘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 neighbourhood garden centres. 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 fertilise 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 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.
Should I prune my catmint once it blooms?
I make an effort to visit the garden at least once per week to identify the upcoming task. I’m pruning, doing some light weeding, and keeping an eye out for new garden problems right now. On this day, February 8, 2020, I can see that the catmint needs a haircut. They’re wearing a grayish-brown coat from the autumn 2017 collection and they appear pretty winter-haggard.
One of my favourite groundcovers is Nepeta x faassenii, most commonly referred to as catmint. The list of stress-free and simple garden plants undoubtedly includes this sun-loving perennial, which blooms profusely in the summer, is an excellent pollinator plant, and is strong as nails. This cat can be cut back at any time of the year, as severely as you like, and as frequently as you choose.
If you’re preparing for the test, you should know that Nepeta x faassenii and its cultivars are sterile crossbreeds of Persian catmint, Nepeta racemosa, and lesser catmint, Nepeta nepetella. From mid-spring through the fall, masses of violet to dusky-sky blue flowers can be anticipated with very little irrigation. During the summer, if the plant begins to appear overly flowered or worn out, trim it to a height of 6 inches and wait a week.
The plant under consideration today is depicted above. Old, grey growth is visible and is pleading to be carried away and dumped on the enormous compost heap in the sky. A tiny bit of green may be seen peeking through, along with some much younger growth far below.
The plant would currently appear happier and there would be much less grey growth if I had clipped this back at least once throughout the summer.
The new growth is easily seen when you pull the plant to one side. I’ll go right to the good things by cutting everything else. Take note of how the green above and below the plant differs in hue. The yellow-green colour (above) is peeling off, exposing the grey-green colour (below).
It was far too simple. With my straight nose clippers, it required 12 cuts. With my felcos, I could have finished it in four. I cut the entire plant down to a height of about 2 inches.
I’m done now! Walk away if you feel comfortable with a few dead stalks sticking out. You’ve finished.
Let’s move a little closer if you’re still reading. If those stems are driving you crazy, either remove the entire stem or snip-prune each one back to just above something green.
Is it necessary to deadhead catmint?
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.
How is a catmint plant cared for?
Use ‘Cat’s Meow’ catmint, Angelface Blue Angelonia, and Snowstorm Giant Snowflake bacopa in mixtures, like in this ‘Brooklyn Heights recipe’. By Proven Winners, the image.
Water requirements:
Until they become established during their first growing season, water new plants or transplants often. After that, they will seldom ever require more watering. Regular watering will help keep the soil moist for Japanese catmints (N. subsessilis).
Pruning:
After the first blooming period has ended, certain plants may enter a summer doldrum. Your plants will be revitalised for a second bloom cycle and will develop lush new foliage if you cut them back by a third or more. They frequently repeat bloom even without being sheared, albeit not quite as prolifically.
Because hybrid seeds are sterile, deadheading is not essential to stop plants from self-seeding. However, it might encourage the growth of new flowers.
Propagating:
One of the simplest plants to divide, doing so every three to four years will keep it healthy. Simply divide rooted pieces of an established plant with a spade, and then replant the divisions with a foot or so of space between them. Before flower buds form in the spring, stem cuttings can also be obtained and utilised for propagation.
Pests and Diseases:
may be troubled by thrips, which work best when treated with neem oil or insecticidal soap. Pests like mosquitoes, aphids, squash bugs, cabbage loopers, and more are reported to be deterred by catmint, especially catnip (N. cataria).
Which perennials shouldn’t have their stems pruned in the fall?
Protecting perennials is necessary. Garden mums (Chrysanthemum spp.), anise hyssop (Agastache foeniculum), red-hot poker (Kniphofia uvaria), and Montauk daisy are examples of minimally hardy perennials that shouldn’t be reduced in size (Nipponanthemum nipponicum).
Which plants require pruning in the fall?
Many perennials should have their stems pruned in the fall. To help prevent illness and decay in the early spring, prune foliage to just a few inches above the ground and be sure to remove any clutter from the garden.
Cut the foliage all the way to the ground and don’t compost it if perennials (such Bee Balm or Phlox) had disease this past season. Put it in the trash or dispose of it in a location far enough from the garden to prevent the illness from spreading to other plants. After dealing with any unhealthy plants, make sure to clean your pruners with a solution of bleach and water.

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.
