How to Grow Rosemary from Cuttings Successfully

Rosemary can be grown from cuttings, and taking several healthy shoots gives you a better chance than relying on just one.

The right growth stage, a free-draining medium and steady moisture matter more than a complicated setup.

It does take patience, though; rosemary cuttings like to take their time.

Choose a Good Time for Rosemary Cuttings in Your Region

Choose a spell of mild weather when the rosemary is actively growing, rather than taking cuttings during a cold snap or a stretch of punishing heat.

In many places, that means spring or early summer, but the right window depends on your local conditions.

In New Zealand, look for fresh growth after the cooler months, adjusting for your region’s warmth and frost pattern.

In the United States, spring or early summer often suits Northern Hemisphere gardens, once severe frosts have passed and before summer heat becomes stressful.

Mild-winter areas may have a longer window than places with hard freezes.

There’s no single calendar month that works everywhere.

If the parent plant is putting out healthy new growth and the weather is settled, you’re likely to have a better start.

Avoid taking cuttings just before frost, when young plants have little time to establish, or during very hot weather, when they can dry out quickly.

A sheltered spot and a little patience are more useful than trying to follow a date on the calendar.

Select Firm, Healthy, Non-Flowering Shoots

Look for firm, healthy shoots that are neither very soft and floppy nor old and woody.

The best choices are often newer stems that have begun to firm up but still bend a little, with fresh green leaves and no signs of damage.

Skip stems with flowers or buds if you can.

A flowering shoot is busy putting energy into blooms, while a non-flowering one can put more into forming roots.

Also leave behind any stems that look shrivelled, spotted or pest-damaged; there’s no need to give a doubtful cutting extra responsibility.

Use clean scissors or secateurs to take several shoots from different parts of the plant, without stripping it bare.

Choose a healthy parent plant that’s growing well, since weak or stressed growth is less likely to make a sturdy start.

If you’re unsure which stems are suitable, take a few of the firmest fresh shoots.

Some may not root, so starting with a small handful is sensible, not wasteful.

Prepare the Cuttings for Rooting

Before planting, tidy each cutting so the section that will sit in the mix is bare.

Pinch or snip off the leaves from the lower part of the stem, taking care not to damage the stem itself.

Those leaves would be buried in the damp medium, where they can decay rather than help the cutting.

Leaving foliage on the upper part gives the shoot leaves to support its growth while roots begin to form.

Handle the stems gently, and keep the prepared cuttings out of direct sun while you work so they don’t dry out.

If the cut ends have been sitting around for a while, make a fresh cut at the base with clean scissors before planting.

Rooting hormone is optional; you can try it if you already have some, but it isn’t essential for a straightforward home attempt.

Have the pot and mix ready before stripping the leaves, then plant the cuttings soon after preparation.

This keeps the process simple and avoids leaving a row of bare stems on the bench while you hunt for a suitable container.

Plant Cuttings in a Free-Draining Mix

Fill a small pot or tray with a free-draining propagation mix, then make a hole for each stem so the bare section can sit in the medium without leaves getting buried.

Gently firm the mix around each cutting to hold it upright; don’t pack it down hard, as young roots need air as well as moisture.

A standard seed-raising mix with extra perlite or coarse sand can help drainage.

If you’re reusing a container, make sure it has drainage holes and is clean.

Rosemary dislikes sitting in soggy mix, so ordinary garden soil in a pot is usually a poor choice.

Water gently until the mix is evenly moist, then let excess water drain away.

Place the pot in bright light out of harsh direct sun, and keep the mix lightly moist rather than wet.

A clear cover can help hold humidity, but lift it now and then for fresh air.

Once roots have formed, gradually remove the cover so the cuttings adjust to the room or sheltered outdoor spot.

Rooting takes time, and not every cutting will take.

Choose a few healthy shoots, prepare a little pot of draining mix and give them time; starting with several improves your chances without guaranteeing every one will root.

Keep Cuttings Lightly Moist in Bright, Gentle Light

Once the cuttings are in place, the main thing is keeping their growing mix from drying out without leaving it waterlogged.

Check the surface every so often; if it feels dry, water gently and let any excess drain away.

A clear cover can help slow moisture loss, but it shouldn’t turn the pot into a stuffy little greenhouse.

Set the pot somewhere bright, away from harsh direct sun.

Strong sun can heat the covered pot and dry the stems before they have roots to take up water.

A bright windowsill out of the hottest sun or a sheltered spot with good indirect light can work well.

If you’ve used a cover, lift it now and then to let fresh air circulate and check for excess condensation.

You’re aiming for lightly moist mix and healthy-looking stems, not a puddle or a cloud of dampness.

Rosemary can take its time, so resist the urge to water on a fixed schedule; let the mix tell you what it needs.

Check for Roots and Ease the Cover Off

Rosemary cuttings don’t announce that they’ve rooted, so give them time rather than checking by pulling at the stems.

A gentle tug can disturb new roots just as they’re getting established.

Look for fresh growth, or roots showing at the pot’s drainage holes, as clues that the cuttings may be ready to adjust to less humidity.

When roots have formed, start easing off the cover gradually instead of removing it all at once.

Open it a little more over several days, keeping the mix lightly moist and the pot in bright, gentle light.

This gives the young plants time to adapt to the air around them without drying out suddenly.

Once a cutting is growing steadily and has a good set of roots, you can move it into its own pot if several share a container.

Handle the roots gently and use a free-draining mix.

Some cuttings may not make it, even when you’ve done things carefully; starting with a few healthy shoots gives you a better chance of having a sturdy young rosemary plant to keep growing.

Choose a few suitable shoots from a healthy rosemary plant, prepare a small pot of free-draining mix and give the cuttings time.

Starting with several is a sensible way to improve your chances, even though not every cutting will root.

A little patience now can mean more fragrant rosemary to enjoy later.
