How to Take Stem Cuttings: Root Softwood in 2 Weeks, Semi-Ripe in 4, Hardwood All Winter
Softwood roots in 2–4 weeks, semi-ripe in 4–8, hardwood over winter — here’s exactly how to take each type, when to cut, and why node placement changes everything.
Why You Should Always Cut Just Below a Node
Every node on a plant stem contains meristematic tissue — specialized cells that retain the ability to differentiate into roots, shoots, or leaves. The spaces between nodes (internodes) contain no such cells. A cutting made through an internode has no tissue capable of generating roots, regardless of how well you care for it afterward.
When you sever a stem, the cutting’s remaining auxin (indole-3-butyric acid, or IBA — a natural plant growth hormone) is transported toward the base and accumulates at the cut surface. This auxin flood signals the meristematic cells at the node to switch from producing shoots to producing adventitious roots — roots that form on non-root tissue in response to wounding.
Rooting powder products simply deliver that signal at higher concentration than the plant generates on its own, accelerating root initiation and improving success across a batch of cuttings. That’s the mechanism. Everything else — the humidity dome, the bottom heat, the free-draining compost — just creates conditions where that process can run without interruption.
Timing at a Glance
| Cutting type | When to take | Wood stage | Rooting time | Best for |
|---|---|---|---|---|
| Softwood | May–June | Flexible, green, no bark | 2–4 weeks | Perennials, hydrangea, fuchsia, coleus |
| Semi-ripe | July–September | Firm base, soft tip | 4–8 weeks | Lavender, rosemary, camellia, hebe |
| Hardwood | November–February | Fully woody, dormant | 12+ months | Roses, dogwood, willow, currants |
Softwood Cuttings (May–June)
Softwood is the new growth produced this season — green, pliable shoots that snap cleanly but haven’t yet developed bark. The RHS notes that softwood cuttings have the highest rooting potential of any stem cutting type, which is why propagators use this window to multiply fuchsia, hydrangea, and tender perennials most aggressively.

The catch: softwood is the most moisture-sensitive cutting type. Without leaves and without roots, a softwood cutting can desiccate within hours on a warm afternoon.
Step 1: Collect early morning
Cut 4–6-inch (10–15 cm) stems before 10 a.m. when shoots are fully hydrated. Non-flowering stems root far more readily — a stem in bud is directing energy into flower production, not root initiation. If you must wait until later in the day, place cuttings immediately into a sealed plastic bag to slow moisture loss.
Step 2: Prepare the cutting
Trim cleanly just below a leaf node using a sharp, clean blade. The cut should land within 5 mm of the node — beyond that, the distance from meristematic tissue reduces rooting reliability. Remove all but the top two or three leaves. For large-leaved plants like hydrangea, cut each remaining leaf in half with scissors to reduce transpiration demand.
Step 3: Apply rooting hormone (optional but helpful)
Dip the bottom inch of the stem in rooting powder or gel. For softwood, low-strength formulations (0.1% IBA) are sufficient — the high-strength products intended for hardwood can actually inhibit rooting in delicate young tissue at that concentration.
Step 4: Insert into rooting medium
A 50:50 mix of perlite and potting compost works well — water-retentive but free-draining is the goal. Push a pencil or dibber into the medium first to create a hole; inserting the cutting directly can scrape off rooting hormone. The lowest remaining leaves should sit just above the compost surface.
Step 5: Create humidity
Enclose the pot in a clear plastic bag or propagation dome and place in bright, indirect light. Bottom heat of 65–75°F (18–24°C) speeds rooting significantly. Avoid direct sun — the enclosed environment amplifies heat, and softwood scorches easily.
Step 6: Wait, then check
Resist disturbing the cuttings for at least two weeks. The first sign of rooting is gentle resistance when you lightly tug a cutting. Once roots are 1–2 inches long, harden off by gradually opening the humidity dome over five to seven days before potting individually into regular potting mix.
Houseplants propagate just as readily from this method. For plant-specific timing and medium recommendations, see our guide to pellionia stem cuttings — this trailing plant roots in two to three weeks and is one of the easiest houseplant propagations there is.
Semi-Ripe Cuttings (July–September)
By mid-July, the spring’s new growth has started to firm up. The base of this year’s shoots has become woody and stiff while the tips remain green and pliable. This in-between stage — semi-ripe, sometimes called semi-hardwood — is the propagation window for woody shrubs, Mediterranean herbs, and broad-leaved evergreens.
Semi-ripe cuttings are less prone to wilting than softwood because the partially firmed tissue retains moisture better. The trade-off: they take longer to root, typically four to eight weeks rather than two to four.
The snap test
Bend the stem back on itself. Semi-ripe wood snaps cleanly at the base but bends without breaking at the tip. If the whole stem bends without snapping anywhere, it’s still softwood. If it snaps throughout with equal firmness top to bottom, it’s already moved into hardwood territory and will root more slowly at this stage.
Step-by-step for semi-ripe
Select 4–6-inch (10–15 cm) stems from healthy, disease-free growth. Cut in the morning. Trim cleanly below a node and remove the lower third of leaves. For large-leaved plants like camellia, halve the remaining leaves with scissors — each leaf is still transpiring water, and the cutting has no roots to replace it.
For harder-to-root shrubs such as camellia or magnolia, make a 1-inch upward slice through the bark at the cutting base before applying hormone. This technique, called wounding, exposes more cambium tissue and increases the surface area available for root initiation.
The RHS recommends a rooting medium of 50% free-draining potting compost and 50% sharp sand or perlite for semi-ripe cuttings. Summer cuttings taken in July and August root without bottom heat; September cuttings benefit from a heated propagator set to 65°F (18°C).

Hardwood Cuttings (November–February)
Hardwood cuttings are the most forgiving of the three types. The plant is dormant, water loss is minimal, and the cuttings can sit outside all winter while you largely ignore them — and still root successfully by autumn. This is the method for roses, dogwood, willows, currants, gooseberries, and most deciduous shrubs.
When to take them
Take hardwood cuttings after leaf drop — typically November in USDA Zones 5–7, December in Zone 7–8 — and before the first swelling of spring buds. December is the traditional UK window. In warmer US zones (8–9), where some plants don’t fully drop leaves, wait until stems feel firm and slightly rough to the touch, even if the plant is still technically evergreen.
How to cut
Select pencil-thick stems from the current season’s growth and cut 6–10-inch (15–25 cm) sections. The top cut goes on a slant, 1 cm above an outward-facing bud — the angle deflects rain away from the cut surface, reducing rot risk over a wet winter. The base cut is straight across, directly below a node.
Outdoor trench method
The simplest approach for large numbers of cuttings: dig a narrow trench 8 inches (20 cm) deep in a sheltered, partially shaded spot. Add a thin layer of grit at the base for drainage. Push cuttings in at 6-inch intervals with two-thirds of each cutting below ground. Firm the soil back. That’s it — check after frosts and firm back if the ground has heaved them upward. Leave until the following autumn before transplanting.
Pot method
For smaller quantities or cuttings you want to monitor, fill 6-inch pots with gritty compost (one part potting mix, one part grit or coarse perlite) and insert cuttings to two-thirds depth. Place in an unheated cold frame or sheltered position against a wall. Rooting hormone at high strength (0.8–1.6% IBA) improves results for roses and other slower-rooting species.
Woody-stemmed houseplants can also be propagated by a modified hardwood approach when they are semi-dormant. Our guide to fiddle leaf fig cuttings covers stem section propagation in detail, including the specific node spacing that matters for this species.
Do You Need Rooting Hormone?
Not always — but it makes a measurable difference for difficult-to-root plants.
Rooting hormone products contain IBA, the same auxin that accumulates naturally at a cut node. They work by delivering that signal at higher concentration than the plant generates alone, which accelerates root initiation and improves uniformity across a batch. For easy-rooting plants — willow, coleus, most softwood perennials — rooting hormone is rarely necessary. For semi-ripe and hardwood cuttings of lavender, rosemary, roses, and camellia, it can shift success rates significantly.
Research from MSU Extension finds that liquid formulations outperform powders at equivalent concentrations. Gel products like Clonex combine IBA with nutrients and anti-microbial agents for a practical all-in-one. Powder works too when used correctly — wet the cutting base in plain water first so the powder adheres, and tap off any excess.
| Cutting type | IBA concentration | Product example |
|---|---|---|
| Softwood | 0.1–0.3% | Hormex #3 |
| Semi-ripe | 0.3–0.8% | Hormex #8 |
| Hardwood | 0.8–1.6% | Hormex #16 |

Tools That Actually Make a Difference
Most propagation equipment lists are padded. These four items genuinely change outcomes:
Sharp bypass pruners or a grafting knife. A clean cut seals quickly and keeps vascular tissue intact. Crushing the stem base with a blunt blade is one of the single biggest failure causes — it flattens the xylem and phloem, disrupting water uptake before rooting can begin. Find bypass pruners on Amazon.
Disinfectant for the blade. Diluted bleach (1 part bleach to 9 parts water) or isopropyl alcohol, applied between plants. Disease spreads via contaminated blades faster than almost any other route in propagation.
Clear plastic bag or propagation dome. Not decorative — this is the humidity control that keeps softwood cuttings from desiccating before roots form. A propagation tray with humidity dome on Amazon makes managing multiple batches easier.
Perlite. The single most useful rooting medium additive. Perlite holds moisture at the particle surface while maintaining oxygen-rich air pockets around the stem base — developing roots need oxygen as much as water. Perlite for propagation on Amazon.
Why Cuttings Fail — and What to Do
| Symptom | Most likely cause | Fix |
|---|---|---|
| Wilts within 24 hours | Taken mid-afternoon or no humidity dome | Take cuttings before 10 a.m. and enclose immediately in a humidity dome |
| Rots at the base | Overwatering or poor drainage in rooting medium | Reduce watering, increase perlite ratio, check drainage holes are open |
| No roots after 8 weeks (softwood) | Cutting taken too late in season, or from a flowering stem | Restart with non-flowering stems in May–June |
| Callus forms but no roots | Insufficient auxin or too little light | Apply rooting hormone on next batch and move to brighter indirect light |
| Leaves drop, stem stays green | Normal moisture-conservation response | Leave undisturbed; check for rooting at 6 weeks |
| New leaves but stem pulls free easily | Using stored energy, not yet rooted | Repot in fresh medium, continue humidity regime until root system establishes |
| White mold on stems | Excessive humidity with no airflow | Remove affected cuttings; briefly open dome daily for 15 minutes to ventilate |
Frequently Asked Questions
When is the best time of year to take stem cuttings?
It depends on the cutting type: softwood from May to June, semi-ripe from July to September, hardwood from November through February when plants are dormant. Matching the cutting type to the right window is more important than any other variable.
Can I take stem cuttings in summer?
Yes — July through September is the semi-ripe window, ideal for lavender, rosemary, camellia, and most evergreen and deciduous shrubs. Some softwood species can also be taken into early July if new growth is still green and pliable.
Do stem cuttings need direct sunlight?
No. Bright indirect light is best during rooting. Without roots, a cutting cannot replace water lost through transpiration — direct sun accelerates moisture loss faster than an unrooted cutting can manage, even inside a humidity dome.
Can I root stem cuttings in water?
Yes, for many soft-stemmed species and houseplants. However, roots formed in water are structurally different from soil roots — thicker-walled and less efficient at mineral uptake. Water-rooted cuttings should be potted up once roots reach about an inch long, before they become fully adapted to aquatic conditions and struggle to transition.
How do I know when a stem cutting has rooted?
Gentle resistance when lightly tugged is the most reliable sign. New leaf growth is encouraging but not definitive — cuttings can push new leaves using stored energy before a root system has formed. When in doubt, wait six to eight weeks and carefully unpot to check.
