How to Take a Rosemary Cutting: Step-by-Step Guide

By James Wilson · January 24, 2026

To take a rosemary cutting, select a healthy 4-6 inch stem from new growth, remove the lower leaves, dip the cut end in rooting hormone, and plant it in well-draining soil. Keep it in bright, indirect light and maintain consistent moisture for 3–4 weeks until roots develop.

Why Propagate Rosemary from Cuttings?

Propagating rosemary (Rosmarinus officinalis) from cuttings is one of the most reliable and effective methods for growing new plants. Unlike seed propagation, which can be slow and inconsistent, cuttings produce genetically identical clones of the parent plant, ensuring desirable traits like fragrance, flavor, and growth habit are preserved.

Cuttings have a higher success rate than seeds
Faster establishment compared to seed-grown plants
Maintains the exact characteristics of the parent plant
Ideal for preserving heirloom or high-performing varieties

Best Time to Take a Rosemary Cutting

The optimal time to take a rosemary cutting is during the active growing season, typically in late spring to early summer (May to July). During this period, the plant produces softwood cuttings that root more readily.

Seasonal Guidelines for Rosemary Cuttings

Spring (April–June): Best for softwood cuttings — highest rooting success
Summer (July–August): Semi-hardwood cuttings possible, but require more humidity
Fall (September–October): Possible indoors with supplemental lighting
Winter (November–March): Not recommended outdoors; low light and cold reduce rooting success

Selecting the Right Stem for Your Cutting

Choosing the correct stem is crucial for successful propagation. Focus on non-flowering shoots with vigorous growth.

Characteristics of an Ideal Rosemary Cutting

Length: 4–6 inches (10–15 cm)
Type: Softwood or semi-hardwood (flexible but not too tender)
Location: New growth from the current season
Health: Free from pests, disease, or stress signs
No flowers: Remove any flower buds to direct energy toward root development

Step-by-Step Guide to Taking a Rosemary Cutting

Prepare your tools: Use clean, sharp pruning shears or scissors sterilized with rubbing alcohol.
Select a stem: Choose a healthy, non-flowering shoot from the upper part of the plant.
Make the cut: Cut just below a leaf node at a 45-degree angle to increase surface area for root formation.
Remove lower leaves: Strip off leaves from the bottom 2–3 inches to prevent rotting in soil.
Apply rooting hormone (optional but recommended): Dip the cut end in powdered or liquid rooting hormone to boost success rates.
Plant the cutting: Insert into a well-draining potting mix (e.g., perlite-sand-soil blend).
Water gently: Moisten the medium without soaking it.
Provide proper environment: Place in bright, indirect light with moderate humidity (cover with plastic dome if needed).
Maintain conditions: Keep soil slightly moist and ventilate daily to prevent mold.
Check for roots: After 3–4 weeks, gently tug the stem; resistance indicates root development.

Recommended Rooting Mediums and Containers

The choice of growing medium significantly affects rooting success. Rosemary requires excellent drainage to avoid stem rot.

Medium	Rooting Success Rate (%)	Time to Root (Days)	Drainage Quality	Comments
Perlite + Peat (1:1)	85	21–28	Excellent	High aeration, low nutrient retention
Coarse Sand	70	28–35	Good	Affordable, reusable, may compact over time
Potting Soil + Perlite (2:1)	78	25–32	Good	Balanced moisture retention and drainage
Rockwool Cubes	82	24–30	Excellent	Sterile, pH-stable, ideal for hydroponic setups
Water Only	50	30–45	Poor	Risk of rot; roots may struggle when transplanted

Table data source:1, 2

Data shows that perlite-peat mix yields the highest rooting success and fastest root development due to superior aeration and moisture balance. Water-only propagation has significantly lower success and longer rooting times, making it less reliable for rosemary.

Caring for Your Rosemary Cutting After Planting

After planting, proper care ensures strong root development and minimizes failure risks.

Light: Provide 6–8 hours of bright, indirect sunlight daily. Use grow lights indoors (14 hours/day).
Temperature: Maintain 65–75°F (18–24°C); avoid cold drafts or overheating.
Humidity: Cover with a clear plastic bag or dome for first 1–2 weeks to retain moisture, removing daily for ventilation.
Watering: Keep soil lightly moist but never soggy; let top layer dry slightly between waterings.
Fertilizing: Do not fertilize until roots are established (after ~4 weeks).

When and How to Transplant Rooted Cuttings

Once your cutting has developed a robust root system (typically 3–4 weeks), it's ready for transplanting.

Signs Your Cutting Is Ready to Transplant

New top growth appears
Gentle tug test shows resistance (indicating root formation)
Roots visible through drainage holes (if using small pots)

Transplanting Steps

Choose a pot with drainage holes, 4–6 inches in diameter.
Use a well-draining mix such as cactus/succulent soil or amend regular potting soil with sand or perlite.
Water the new container thoroughly after planting.
Place in full sun (6+ hours direct sunlight) gradually acclimate if previously shaded.
Begin light feeding after 2–3 weeks using half-strength balanced fertilizer.

Common Problems and Troubleshooting Tips

Even with careful handling, issues can arise during propagation.

Rotting stem: Caused by overwatering or poor drainage. Use sterile medium and ensure good airflow.
Drying out: Increase humidity with a cover or misting, but avoid wetting foliage excessively.
No root development: May result from old wood, wrong season, or lack of warmth. Try again with fresh softwood cuttings in spring.
Mold or fungus: Clean tools, use sterile soil, and ventilate daily under cover.

Frequently Asked Questions About Taking Rosemary Cuttings

How long does it take for a rosemary cutting to root?

Rosemary cuttings typically root within 3 to 4 weeks when kept in optimal conditions (65–75°F, bright indirect light, and well-draining soil). Using rooting hormone can speed up the process by 5–7 days.

Can I root rosemary in water?

Yes, but it's less reliable than soil or inert media. Water-rooted cuttings often develop weak roots and are prone to rot. If using water, change it every 2–3 days and transplant carefully once roots reach 1–2 inches.

Do I need rooting hormone for rosemary cuttings?

While not strictly necessary, rooting hormone increases success rates from around 60% to over 80%. It’s especially helpful for beginners or when propagating in suboptimal conditions.

Why are my rosemary cuttings turning brown?

Browning usually indicates rot or desiccation. Overwatering, poor drainage, or low humidity can cause browning. Ensure the medium drains well, provide gentle airflow, and avoid direct sun exposure during rooting.

Can I take rosemary cuttings in winter?

You can take cuttings indoors in winter if you have access to bright grow lights and maintain temperatures above 60°F. However, outdoor winter cuttings are unlikely to succeed due to cold and reduced light levels.

How many cuttings can I get from one rosemary plant?

A mature rosemary plant can safely provide 4–6 cuttings at a time without stress. Allow at least 6–8 weeks between harvesting sessions to let the plant recover and produce new growth.
