Catmint, a member of the mint family, is a popular perennial flowering plant known for its attractive blue or purple flowers and its ability to attract cats. However, if you want to enjoy the beauty and benefits of catmint in your garden year after year, it is essential to know how to repopulate it. By following the right techniques, you can easily propagate catmint and ensure a continuous supply of these charming plants in your outdoor space.
The most common method of repopulating catmint is through division. This process involves splitting an existing catmint plant into smaller sections, each with its root system. Divide catmint plants in spring or fall, when the weather is cool. Dig up the entire plant, and use a sharp knife or spade to cut the root ball into several pieces. Each piece should have a few healthy roots and at least one stem. Replant the divisions in well-drained soil, spacing them about 12 inches apart.
Catmint can also be repopulated through stem cuttings. Take cuttings from healthy, non-flowering stems in late spring or early summer. Remove the lower leaves from the cuttings, and dip the ends in rooting hormone. Insert the cuttings into a pot filled with seed starting mix. Keep the soil moist, and place the pot in a warm, sunny spot. Roots will form in about 4-6 weeks. Once the cuttings have developed a good root system, they can be transplanted into the garden.

Dividing Catmint Roots
Catmint is a popular perennial herb that is easy to grow and maintain. It is a low-growing plant with attractive foliage and spikes of blue or purple flowers. Catmint can be propagated by seed, but the most common method is by dividing the roots.
Dividing catmint roots is a simple process that can be done in the spring or fall. To divide catmint roots, follow these steps:
- Dig up the catmint plant.
- Use a sharp knife or spade to divide the root ball into several smaller sections.
- Each section should have at least one healthy root and a few shoots.
- Replant the divisions in well-drained soil.
- Water the divisions deeply and keep them moist until they are established.
Here is a more detailed explanation of steps 2 and 3:
Step 2: Dividing the Root Ball
When dividing the root ball, it is important to make clean cuts. Use a sharp knife or spade and avoid tearing the roots. Each division should be large enough to support itself and have a few healthy shoots.
Step 3: Selecting Healthy Divisions
When selecting healthy divisions, look for sections that have at least one healthy root and a few shoots. The roots should be white or cream-colored and firm. Avoid divisions with any signs of disease or damage.
| Characteristic | Healthy Division | Unhealthy Division |
|---|---|---|
| Roots | White or cream-colored, firm | Brown or black, soft |
| Shoots | Green, healthy | Yellowed, wilted |
| Overall appearance | Vigorous, healthy | Weak, damaged |
Taking Catmint Cuttings
Catmint (Nepeta spp.) is a hardy, easy-to-grow perennial that adds a splash of color to your garden. Propagating catmint from cuttings is a quick and easy way to create new plants.:
Time of year
The best time to take catmint cuttings is in late spring or early summer, when the plants are actively growing. Avoid taking cuttings during hot, dry weather, as the cuttings are more likely to wilt and fail.
Selecting stems
Select healthy stems that are 4-6 inches long. Look for stems that are not flowering, as flowering stems may not root as well. Remove any leaves from the bottom 2-3 inches of the stem.
Rooting
There are two methods for rooting catmint cuttings:
- In water: Place the cuttings in a glass or jar filled with water. Change the water every few days to prevent the cuttings from rotting. Once the cuttings have developed roots that are 1-2 inches long, they can be transplanted into pots or the garden.
- In soil: Dip the bottom of the cuttings in rooting hormone and plant them in a pot filled with a well-draining potting mix. Keep the soil moist but not soggy. Once the cuttings have developed roots, they can be transplanted into the garden.
Tip:
To increase the chances of success, you can take multiple cuttings from each stem. If one cutting fails to root, you will have backups.
Encourage Self-Seeding
To encourage catmint to self-seed, follow these steps:
- Allow Flowers to Bloom: Let the catmint flowers fully bloom and develop seed heads.
- Deadhead Spent Blooms (Optional): You can remove spent blooms to prevent unwanted seedlings, but this is not always necessary.
- Collect Seeds: When seed heads turn brown and start to split open, cut them off and collect the seeds.
- Sow Seeds in Fall or Spring: Broadcast the seeds directly onto bare soil in late fall or early spring. Cover lightly with soil and keep moist.
Additional Tips for Self-Seeding Catmint

| Step | Details |
|---|---|
| Collecting Seeds | Collect seeds from fully mature seed heads that are brown and splitting open. |
| Sowing Time | Sow seeds in late fall or early spring when soil is cool and moist. |
| Sowing Depth | Cover seeds lightly with soil, no more than ⅛ inch deep. |
| Germination | Seeds typically germinate within 10-21 days. |
| Seedling Care | Keep seedlings moist and protect from extreme temperatures. |
Soil Preparation for Catmint
To ensure optimal growth and flourishing catmint plants, meticulous soil preparation is paramount. Here’s a comprehensive guide to creating an ideal soil environment for your catmint:
1. Soil pH
Catmint thrives in slightly alkaline to neutral soil pH levels between 6.5-7.5. If your soil is acidic, adding lime can help raise the pH. Conversely, if the soil is too alkaline, adding sulfur or iron chelates can lower the pH.
2. Drainage
Catmint requires well-drained soil that prevents waterlogging. Amend heavy clay soil with compost or sand to improve drainage. Raised beds are an excellent option if your soil is prone to water accumulation.
3. Organic Matter
Enrich the soil with plenty of organic matter, such as compost or manure. This will enhance soil fertility, improve water retention, and provide essential nutrients for the catmint plants.
4. Fertilization
Catmint generally does not require heavy feeding. Fertilize lightly in the spring with a balanced fertilizer, such as a 10-10-10 blend. Avoid over-fertilizing, as excessive nitrogen can promote foliage growth at the expense of flowers.
5. Soil Testing and Amendments
Conduct a soil test to determine the specific needs of your soil. Based on the results, amend the soil as necessary to adjust pH levels, improve drainage, or add nutrients. The following table provides a summary of potential soil amendments:
| Purpose | Amendment |
|---|---|
| Raise pH | Lime |
| Lower pH | Sulfur, Iron chelates |
| Improve drainage | Compost, Sand |
| Enhance fertility | Compost, Manure |
Seedling Care
After sowing the seeds, gently press them into the soil but do not cover them, as they need light to germinate. Keep the soil moist but not soggy. Seedlings should emerge within 1-2 weeks.
Once seedlings have developed their first set of true leaves, thin them out to 6-8 inches apart to give them room to grow.
Transplanting
When seedlings are 2-3 inches tall, they can be transplanted into their final location in the garden.
Select a site that receives full sun to partial shade and has well-drained soil. Dig a hole twice the width of the root ball and just as deep.
Carefully remove the seedling from its container and loosen any roots that have become bound.
Place the plant in the hole and backfill the soil, gently tamping it down around the base of the plant.
Water the plant thoroughly and apply a layer of mulch around the base to help retain moisture and suppress weeds.
Spacing
| Plant Size | Spacing |
|---|---|
| Compact | 6-8 inches apart |
| Upright | 12-18 inches apart |
Root Division Technique
Root division is a simple and effective way to propagate catmint plants. It involves dividing the plant’s root system into smaller sections, each of which can be planted to create a new plant. Here’s a detailed guide to the root division technique:
1. Prepare the Catmint Plant
Choose a healthy, mature catmint plant that is not flowering. Dig around the base of the plant to loosen the soil and expose its roots.
2. Divide the Roots
Use a sharp knife or spade to divide the root system into several sections, each with a few healthy roots attached. Ensure that each section has at least one growing point.
3. Replant the Sections
Dig holes in the desired planting location, spacing them about 18-24 inches apart. Place each root section in a hole, spreading the roots around it. Fill in the holes with soil and firm it down gently.
4. Water the Plants
Water the newly planted catmint sections thoroughly to help them establish. Water them regularly during the first few weeks until they are well established.
5. Mulch Around the Plants
Spread a layer of mulch around the base of the plants to help retain moisture, suppress weeds, and regulate soil temperature.
6. Remove Flower Spikes
Remove any flower spikes that appear on the newly planted catmint plants to encourage root growth and plant establishment.
7. Patience and Care
It may take several weeks for the newly divided catmint plants to establish and start growing vigorously. Provide them with adequate water, sunlight, and protection from pests and diseases during this time. With proper care, they will eventually develop into healthy, flowering plants that will attract pollinators to your garden.
Timing and Conditions for Cuttings
The ideal timing for taking cuttings of catmint plants is during the active growing season, which typically spans from late spring to early summer. This is because cuttings taken during this time have access to ample sunlight and moisture, promoting successful rooting and growth. Additionally, cuttings should be taken from healthy, disease-free parent plants to ensure the best chance of success.
When selecting stems for cuttings, choose healthy, non-flowering shoots that are approximately 4-6 inches in length. Ensure that the stem has at least two nodes, which are the points where leaves attach to the stem. Nodes are where new roots will emerge during the rooting process.
To prepare the cuttings, remove the leaves from the bottom inch or two of the stem. This will promote root growth while preventing leaves from contacting the potting mix, reducing the risk of rot.
Dip the bottom end of the cutting into a rooting hormone powder to stimulate root growth. While not essential, rooting hormone can significantly increase the success rate of cuttings.
Insert the cutting into a moist, well-draining potting mix. The potting mix should be slightly moist but not soggy. The depth of the cutting should be approximately 1-2 inches.
Create a humid environment around the cuttings by covering them with a plastic bag or placing them inside a humidity dome. This will help prevent the cuttings from drying out and promote root growth.
Keep the cuttings in a warm, well-lit location. The ideal temperature range is 65-75°F (18-24°C). Bright indirect light is suitable, but avoid exposing the cuttings to direct sunlight, as this can scorch the leaves.
Monitor the cuttings regularly and mist them with water as needed to keep the potting mix moist. Within 2-4 weeks, the cuttings should begin to develop roots. Once the roots are well-established, the cuttings can be transplanted into individual pots or into your garden.
Rooting Cuttings in Soil or Water
Catmint, a versatile and low-maintenance perennial, can be easily propagated through rooting cuttings. This method allows for the creation of new plants that are genetically identical to the parent plant. Here’s a step-by-step guide to rooting catmint cuttings in both soil and water:
Soil
- Select Healthy Stems: Choose healthy, non-flowering stems with several nodes (where leaves originate).
- Take Cuttings: Cut 3-4 inch sections with sharp pruning shears, making a clean diagonal cut just below a node. Remove any leaves from the bottom inch of the stem.
- Dip in Rooting Hormone: Optional but recommended. Dip the cut end of the stem in a rooting hormone powder or gel to promote root growth.
- Prepare Soil: Fill a pot or seed tray with a well-draining potting mix. Make a hole in the soil deep enough to accommodate the cutting.
- Insert Cutting: Place the cutting into the hole and firm the soil around it. Water the soil lightly.
Water
- Take Cuttings: Similar to taking cuttings for soil propagation.
- Jar Preparation: Fill a jar or glass with fresh, room-temperature water.
- Insert Cutting: Submerge the cut end of the stem in water, ensuring that several nodes are below the water line.
- Provide Support: Place a skewer or bamboo stick next to the cutting to provide support and prevent it from falling over.
- Change Water Regularly: Replace the water every 2-3 days to keep it fresh and prevent rot.
Tips for Rooting Success
- Maintain warm (65-75°F) and well-lit conditions for optimal root growth.
- Mist the cuttings regularly to keep them hydrated.
- Avoid overwatering, as excess moisture can lead to rot.
- Check for roots regularly. Once roots are 1-2 inches long, they can be transplanted into the garden or a larger pot.
| Rooting Method | Advantages | Disadvantages |
|---|---|---|
| Soil | Higher success rate, more robust rooted plants | Requires more care and attention |
| Water | Requires less effort, less risk of overwatering | Lower success rate, roots may be weaker |
Aftercare for Newly Propagated Catmint
1. Watering: Water deeply and regularly, especially during the first few weeks after propagation. Allow the soil to dry slightly between waterings.
2. Sunlight: Provide ample sunlight for at least 6 hours per day. Catmint prefers full sun to partial shade.
3. Fertilizing: Fertilize newly propagated catmint plants monthly with a balanced fertilizer diluted to half strength.
4. Mulching: Spread a layer of mulch around the base of the plants to retain moisture, suppress weeds, and regulate soil temperature.
5. Overwintering: In cold climates, mulch heavily or cover the plants with a breathable fabric to protect them from frost damage.
6. Pruning: Remove faded flower spikes to encourage additional blooming and prevent seed formation, which can weaken the plant.
7. Divide: Divide established catmint every 3-4 years to maintain vigor and prevent overcrowding.
8. Repotting: If grown in containers, repot into larger pots as needed due to root growth.
9. Disease and Pest Control: Monitor plants for common diseases such as powdery mildew and pests like aphids. Treat promptly with appropriate organic remedies or pesticides.
10. Additional Tips for Success:
| Tip | Benefit |
|---|---|
| Deadhead regularly | Promotes continuous blooming |
| Pinch back tips of stems | Encourages bushier growth |
| Companion plant with other pollinator-attracting species | Creates a diverse and beneficial ecosystem |
| Use as a groundcover or in borders | Adds color, fragrance, and low-maintenance beauty |
