- ‘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!
Can you cut catmint apart?
Plants of catmint will continue to thrive in terms of growth and blooming. But all Nepeta cultivars take to division well, so you can divide them to create new plants. Find a part of the plant in the spring that has underdeveloped branches and a strong root system. Use a spade to cut it vertically.
When can catmint be transplanted?
Catmint can be planted anywhere in the spring once the risk of frost has passed once you’ve selected your location. You’ll have a better chance of experiencing a first-season bloom the earlier you plant them. Plants should be spaced 24 to 30 inches apart; they will grow!
Dig a hole twice the size of the pot around, loosen the dirt on the bottom, and backfill with one to two inches of compost to plant transplants in pots. Place the final plant in place, leveling the top of the root ball with the soil line, and then cover with dirt. Place gently and then deeply water. After its first season, catmint is quite drought-tolerant but still requires an inch of rain per week.
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.
Does catmint get pruned back in the fall?
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 does catmint survive 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 fertilizing 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.
Can catnip be transplanted in the fall?
- Catnip seeds should be sown inside a few weeks prior to the last spring frost. It takes 7 to 10 days for germination. The tiny catnip seeds are challenging to manage.
- Catnip seedlings should be planted in the garden in the middle to late spring. It would be challenging to keep cats away from the plants if you bruise the leaves while transplanting because this releases the oil that attracts cats.
- Plant catnip outside after the last spring frost and continue to do so through the summer, stopping about six weeks before the first fall frost.
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 blooms encourages new flowering. 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 far back should catmint be cut?
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.
When do I cut back my catmint?
Once grown, catmint grows quickly and needs minimal maintenance. Although flowers are generated over a lengthy period of time, it’s a good idea to remove them after blooming to maintain the plant tidy and to promote the development of more. Before new growth arises in the spring, trim back the dead stems once the growth has died back in the late autumn. Delay pruning until early spring if at all feasible because dead leaves are ladybirds’ preferred site to hibernate. Every few years, catmint plants should be divided since huge, crowded clusters cause flowering to drop.
How to propagate catmint
After the plants have grown for a few years, catmint can be divided. The plant should be dug up in the fall or the first few weeks of spring. The clump should be divided into parts, each with a good number of roots and shoot buds, and then replanted in soil that has been improved with well-rotted compost or a soil conditioner. Water thoroughly to help the dirt surrounding the roots settle.
Growing catmint: problem solving
Given the proper growing circumstances, catmint is typically trouble-free, although plants rarely grow well in heavy, poorly drained soil or in shade. Powdery mildew can appear as a white coating on the leaves and stems during exceptionally dry summers. Cut off unhealthy shoots, collect, and discard impacted leaves.
