How to Root Rose Cuttings: 3 Methods Compared

Propagating roses from cuttings is one of the oldest gardening techniques in the book -- and one of the most useful. A cutting taken from a healthy garden rose costs nothing, and if it roots, you get a new plant genetically identical to the parent. The limiting factors are timing, wood selection,.

Propagating roses from cuttings is one of the oldest gardening techniques in the book — and one of the most useful. A cutting taken from a healthy garden rose costs nothing, and if it roots, you get a new plant genetically identical to the parent. The limiting factors are timing, wood selection, and keeping the cutting alive long enough for roots to develop.

I don't grow roses in my Melville yard, so this guide is sourced from NC State Extension, Clemson HGIC, Penn State Extension, and Cornell Cooperative Extension. The three methods compared below — rooting in soil mix, rooting in water, and the much-hyped potato method — have meaningfully different success rates.

Why Own-Rooted vs. Grafted Matters

Most commercial roses are grafted onto a vigorous rootstock (often Rosa multiflora or R. canina) to enhance establishment and vigor. Own-rooted roses — propagated from cuttings — grow more slowly initially but produce no rootstock suckers and, when the top dies back from winter cold, regrow true to the parent variety rather than reverting to rootstock.

Per NC State Extension, own-rooted propagation is particularly valuable for heritage varieties, species roses, and modern shrub roses like the 'Knock Out' series, which root readily from cuttings.

One caution: many patented rose varieties (including some 'Knock Out' and David Austin cultivars) are protected by plant patents, and propagating them without a license is illegal. Per Penn State Extension, check the plant tag for patent or trademark designations before taking cuttings for distribution.

Wood Selection: Softwood vs. Semi-Hardwood

Timing and wood maturity are the two variables most correlated with rooting success.

Softwood cuttings (May—June): Taken from actively growing shoot tips just after a flush of flowers. The wood is green, flexible, and bends without snapping. Per Clemson HGIC, softwood cuttings root fastest (3—4 weeks) but are also the most susceptible to wilting and rot.

Semi-hardwood cuttings (July—August): Taken from the current season's growth after it has begun to firm up. The stem is beginning to harden but has not yet gone woody. Per NC State Extension, semi-hardwood cuttings take slightly longer to root (4—8 weeks) but are more tolerant of the propagation environment.

Hardwood cuttings (late fall, after frost): Taken from dormant, fully hardened canes. Per Cornell Cooperative Extension, hardwood rose cuttings can be rooted but have lower success rates than softwood or semi-hardwood, and the process takes longer. Commonly used for mass propagation of hardy shrub roses.

Taking the Cutting

Per Clemson HGIC:

  1. Select a healthy stem that has recently flowered (for softwood) or is beginning to firm up (semi-hardwood)
  2. Cut a 6—8 inch section, making the bottom cut at a 45-degree angle just below a leaf node
  3. Remove all foliage from the bottom half of the cutting; leave 2—3 leaves at the top
  4. Remove any flower buds or flowers — the cutting should put energy into rooting, not blooming
  5. Make the cut with sharp, clean bypass pruners; ragged cuts increase rot entry points

Per Penn State Extension, take cuttings in the morning when stems are most turgid and process them immediately. If you can't plant right away, wrap cuttings in a damp paper towel, place in a plastic bag, and refrigerate for up to 24 hours.

This is the method supported by every major extension source.

Medium: Per NC State Extension, use a well-drained, low-fertility propagation medium. A 50/50 mix of coarse perlite and peat moss, or coarse perlite alone, works well. Avoid garden soil — it compacts, harbors pathogens, and has too much fertility.

Rooting hormone: Per Clemson HGIC, dip the bottom inch of the cutting in powdered indole-butyric acid (IBA) rooting hormone — the 0.3% IBA formulation labeled for softwood cuttings. Tap off excess powder before inserting. Rooting hormone is not strictly required but meaningfully improves rooting rates and speed.

Inserting the cutting: Make a small hole in the medium with a pencil or chopstick, insert the cutting to about one-third of its length, and firm the medium around it. This prevents the rooting hormone from being wiped off as the cutting is pushed in.

Humidity control: Per Penn State Extension, covering cuttings with a clear plastic dome, a plastic bag, or an inverted plastic bottle maintains the humidity needed to keep leaves from desiccating before roots develop. Mist the interior if the cutting shows signs of wilting.

Light and temperature: Place in bright indirect light — not direct sun, which overheats the enclosed environment. Per Clemson HGIC, bottom heat of 70—75°F dramatically improves rooting rates. A seedling heat mat set to this range is useful if propagating in a cool garage or basement.

Rooting time: Per NC State Extension, softwood cuttings root in 3—4 weeks under ideal conditions; semi-hardwood takes 4—8 weeks. Test for rooting by gently tugging the cutting — resistance indicates root development.

After rooting: Gradually acclimate rooted cuttings to normal humidity over 7—10 days before removing the cover entirely. Transplant into a larger pot with a standard potting mix and grow on for several weeks before planting out.

Method 2: Water Rooting (Moderate Success, Poor Transition)

Water rooting is simple but has a significant drawback.

Process: Per Cornell Cooperative Extension, place the cutting in a clean glass or jar with enough water to cover the bottom 2 inches of stem. Keep the water clean by changing it every 2—3 days. Place in bright indirect light.

Results: Water-rooted rose cuttings do develop roots, but per Clemson HGIC, these roots are structurally different from soil-initiated roots — they are often brittle and lack root hairs. Transition from water to soil frequently causes setback because the water-adapted roots struggle to function in soil conditions. Many gardeners report that water-rooted cuttings die or sulk for months after being potted up.

Verdict: Water rooting can work for roses if the cutting is transitioned to soil promptly (as soon as roots are 1—2 inches long) and given careful attention. It is not the recommended primary method.

Method 3: The Potato Method (Not Supported by Research)

The "potato method" — pushing a rose cutting into a raw potato before inserting both into soil — is widely circulated online. The claim is that the potato provides moisture and nutrients to the cutting.

Per NC State Extension and all reviewed extension sources, there is no research supporting this method over standard soil-medium propagation. Potatoes decompose in soil, can harbor pathogens, and do not provide meaningful nutrients at concentrations that affect rooting. The cutting does not interact with the potato tissue in any horticutlurally meaningful way.

Conclusion: Use a proper propagation medium. The potato method is folklore, not horticulture.

FAQ

Do all rose types root equally well from cuttings? No. Per Clemson HGIC, modern shrub roses (including 'Knock Out' types), miniature roses, and most species roses root readily from cuttings. Hybrid teas root less reliably — they were bred primarily for grafting and many have reduced rooting competence. Old garden roses generally root well.

What is the IBA concentration I should use? Per Penn State Extension, use 0.3% IBA (labeled as "for softwood/semi-hardwood") for rose softwood cuttings. Higher concentrations (0.8% or 1%) are for hardwood cuttings and can inhibit rooting on softwood if overdosed.

Can I take cuttings from a grafted rose and get the same variety? Yes, as long as you take the cutting from wood above the graft union. Per NC State Extension, wood taken from above the graft will root true to the scion variety. Taking a cutting from rootstock growth below the union gives you the rootstock variety, not the garden rose.
