How to take cuttings from a rosemary bush

Take suitable healthy, non-flowering rosemary tips; Cornell Extension’s herb-propagation guide uses 4-6 inch cuttings, remove the lower leaves, and root them in coarse sand or another free‑draining medium kept evenly moist with gentle humidity and bright, indirect light. Alternatively, root in water and pot up once several short roots have formed Gardenary: How to Propagate Rosemary, Better Homes & Gardens via Yahoo.

When and which stems to take

Cornell Cooperative Extension describes taking healthy rosemary tips with green, slightly flexible stems and no flowers. Choose the season and protection for your own climate and cutting method; a calendar date from another region is not a guarantee of suitable growth.

• Best timing: late spring to early summer when plants have soft new growth; autumn cuttings can be overwintered indoors before frost in colder climates Better Homes & Gardens via Yahoo.
• Stem choice: use healthy, flexible green tips; avoid old woody pieces. Many growers succeed with semi-soft tips that are not flowering Gardenary: How to Propagate Rosemary, Rural Sprout.

Rosemary is a Mediterranean herb that prefers full sun and sharp drainage, so plan to grow rooted cuttings in a freely draining potting mix or sandy soil. In colder regions it’s often kept in containers that can be moved under cover Rural Sprout.

What you’ll need

• Clean, sharp pruners or scissors; sanitize before use Rural Sprout.
• Small pots with drainage, or a glass/jar for water rooting Better Homes & Gardens via Yahoo.
• Propagation medium: coarse sand, coconut coir, or a light, well‑draining potting mix. UK readers: use potting compost (not garden compost) and lighten it with sand/perlite for propagation Gardenary: How to Propagate Rosemary, Rural Sprout, Better Homes & Gardens via Yahoo.
• Humidity aid: a clear bag or dome to hold gentle humidity; vent if condensation builds Rural Sprout, Better Homes & Gardens via Yahoo.
• Optional: use a rooting product only if its instructions cover your plant and method Better Homes & Gardens via Yahoo, Gardenary: How to Propagate Rosemary.

Step-by-step: rosemary cuttings in a free‑draining medium

1. Pre-moisten your medium so it’s damp, not soggy, and fill small pots. Make a narrow planting hole with a pencil/dibber Gardenary: How to Propagate Rosemary, Better Homes & Gardens via Yahoo.
2. Snip a 4-6 inch tip from a healthy, flexible stem. Strip leaves from the lower third so you have a bare section to insert. Keep remaining leaves dry and above the medium surface Gardenary: How to Propagate Rosemary, Two Thirsty Gardeners.
3. If using a suitable rooting product, apply it according to its label Gardenary: How to Propagate Rosemary, Better Homes & Gardens via Yahoo.
4. Insert the cutting so the stripped section is below the surface and firm the medium around it to hold it upright. Space multiples a few inches apart if sharing a pot Better Homes & Gardens via Yahoo.
5. Water gently to settle, then cover with a clear bag/dome to hold humidity. Place in bright, indirect light, warm conditions, and keep the medium just moist. Vent if you see mold or leaf softening Rural Sprout, Better Homes & Gardens via Yahoo.
6. Rooting time varies by conditions: typically about 4-8 weeks in substrate. Look for actual root development, including roots visible at drainage holes when present. A very gentle resistance check can help, but avoid repeatedly tugging cuttings. Remove clearly decayed or collapsed material Rural Sprout, Better Homes & Gardens via Yahoo.

Worked example: one cutting in coarse sand

Fill a 9-10 cm (3.5-4 inch) pot with pre-moistened coarse sand. Insert a 5 inch, non-flowering tip after stripping the lower third of leaves. Firm the medium, water to settle it without saturation, and use a loose humidity cover if appropriate. Keep in bright, indirect light and vent the bag if condensation drips. Check for root development before moving to a free-draining potting mix; fresh tip growth alone does not establish that roots have formed Gardenary: How to Propagate Rosemary.

Water rooting (alternative)

Place prepared tips in a small jar with about an inch of clean water, making sure no leaves are submerged. Change water every few days. Once several short roots form (roughly 0.5-1 inch), pot into a free‑draining mix and keep slightly moist while they adapt Gardenary: How to Propagate Rosemary, Better Homes & Gardens via Yahoo, The Coeur d'Alene Coop.

Aftercare: potting on and hardening off

Transplant rooted cuttings into individual small pots filled with a light, free‑draining potting mix and grow in bright light. Let the top of the mix dry slightly between waterings to avoid rot. Before moving outdoors full time, harden plants gradually over 7-10 days to sun and wind; our explainer shows how to stage that move: How do I harden seedlings for transplanting?

Troubleshooting quick fixes

• Cuttings turning black or mushy: reduce moisture, increase air flow, and re-cut using semi-soft, non-woody tips. Vent domes or loosen bags Rural Sprout, Better Homes & Gardens via Yahoo.
• No roots after several weeks: check light and temperature, refresh your medium, and retry with healthier, flexible, non-flowering shoots Rural Sprout, Gardenary: How to Propagate Rosemary.

Propagating rosemary: quick action checklist

• Sanitize pruners and prepare small pots with a damp, free‑draining medium
• Take 4-6 inch non‑flowering tips; strip the lower third of leaves and keep remaining leaves above the medium line
• Insert, firm, water once, then cover loosely for humidity and vent if condensation builds
• Check for root development before potting on and remove clearly decayed cuttings

FAQ

Do I need rooting hormone? It’s optional; many cuttings root without it. A rooting product is optional and should be used only as its label directs; the main priorities are suitable cutting material, an airy medium and appropriate moisture Better Homes & Gardens via Yahoo, Gardenary: How to Propagate Rosemary.

How long will it take? Expect roughly 4-8 weeks in substrate and about 2-6 weeks in water, depending on temperature, light and stem maturity Rural Sprout, Better Homes & Gardens via Yahoo, Gardenary: How to Propagate Rosemary.
