How to Grow Rosemary from a Cutting: Step-by-Step Guide

By James Wilson · January 24, 2026

To grow rosemary from a cutting, take a 4-6 inch stem from a healthy plant, remove the lower leaves, optionally dip in rooting hormone, and place in well-draining soil under bright, indirect light. Keep the soil lightly moist, and roots typically develop within 3–4 weeks.

Why Grow Rosemary from Cuttings?

Propagating rosemary from cuttings is one of the most reliable and efficient methods to grow new plants. Unlike seeds, which can be slow and unpredictable, cuttings produce genetically identical clones of the parent plant, ensuring consistent flavor, aroma, and growth habits.

Cuttings preserve desirable traits like drought resistance or high essential oil content
Faster establishment compared to seed-grown plants
Higher success rate than starting from seed
Cost-effective way to expand your herb garden

Selecting the Right Cutting

What Makes a Good Rosemary Cutting?

Choose a healthy, disease-free mother plant with vibrant green foliage. The best cuttings come from new growth that is semi-hardwood — firm but not woody.

Length: 4 to 6 inches (10–15 cm)
Stem texture: Firm, green, and flexible
Avoid flowering stems; they root less reliably
Take cuttings in spring or early summer for optimal growth

Step-by-Step Guide to Rooting Rosemary Cuttings

Prepare Your Tools: Use clean, sharp scissors or pruning shears sterilized with rubbing alcohol.
Take the Cutting: Snip just below a leaf node at a 45-degree angle.
Remove Lower Leaves: Strip leaves from the bottom 2–3 inches to prevent rot.
Apply Rooting Hormone (Optional): Dip the cut end in powdered or liquid rooting hormone to boost success rates.
Plant in Well-Draining Medium: Use a mix of perlite and peat or cactus soil. Insert the cutting 2 inches deep.
Provide Ideal Conditions: Place in bright, indirect light at 65–75°F (18–24°C). Cover with a plastic bag to maintain humidity if needed.
Water Gently: Keep soil slightly moist but never soggy. Overwatering causes rot.
Check for Roots: After 3–4 weeks, gently tug the stem. Resistance indicates root formation.

Best Soil and Containers for Rosemary Cuttings

Rosemary requires excellent drainage to prevent root rot. A sandy or gritty mix mimics its native Mediterranean habitat.

Soil Component	Purpose	Recommended Ratio
Potting Soil	Base structure	50%
Perlite	Drainage and aeration	30%
Coarse Sand	Prevents compaction	20%

Use small pots (3–4 inches) with drainage holes. Terracotta pots are ideal because they wick away excess moisture.

Common Problems and Troubleshooting

Wilting: Often due to underwatering or low humidity during early rooting.
Mold or Fungus: Caused by overwatering or poor air circulation. Reduce watering and increase ventilation.
No Root Development: May result from old wood, cold temperatures, or lack of light.
Yellowing Leaves: Sign of overwatering or nutrient buildup. Flush soil and reduce irrigation frequency.

Rooting Success Rates: Cutting Type vs. Method

Cutting Age	Rooting Method	Avg. Rooting Time (days)	Success Rate (%)
New Growth (Softwood)	Soil + Hormone	21	85
New Growth (Softwood)	Water Only	28	60
Mature Stem (Hardwood)	Soil + Hormone	35	50
Mature Stem (Hardwood)	Soil Only	42	30
Semi-Hardwood	Soil + Hormone	24	78

Table data source:1, 2

The data shows that softwood cuttings treated with rooting hormone in soil achieve the highest success rate and fastest rooting. Water propagation yields weaker root systems and lower overall viability.

Caring for Newly Rooted Rosemary Plants

Once rooted, gradually acclimate the plant to more direct sunlight over 7–10 days. Transplant into a larger pot or garden bed after 4–6 weeks when roots are well-established.

Light: Full sun (6–8 hours daily)
Water: Allow top inch of soil to dry between waterings
Fertilizer: Light feeding every 4–6 weeks with balanced organic fertilizer
Pruning: Pinch tips to encourage bushy growth

Frequently Asked Questions About Growing Rosemary from Cuttings

Can I grow rosemary from a grocery store sprig?

Yes, but success depends on freshness. Choose sprigs with firm, green stems and no signs of wilting or mold. Avoid pre-packaged, refrigerated rosemary, as it may have been stored too long to root effectively.

How long does it take for rosemary cuttings to root?

Rosemary cuttings typically root in 3–4 weeks when placed in well-draining soil and kept in warm, bright conditions. Using rooting hormone can shorten this time by up to 25%.

Should I use water or soil to root rosemary cuttings?

Soil is preferred over water. While rosemary can root in water, the resulting root system is often weak and poorly adapted to soil transfer. Soil propagation leads to stronger, more resilient plants.

What is the best time of year to take rosemary cuttings?

Spring and early summer are ideal, when the plant is actively growing. This timing ensures the highest metabolic activity and fastest root development. However, indoor cuttings can be taken year-round under controlled conditions.

Why do my rosemary cuttings keep failing?

Common causes include overwatering, using woody stems, insufficient light, or low temperatures. Ensure you're using semi-hardwood cuttings, well-draining soil, and maintaining temperatures above 65°F (18°C) for best results.
