How to Root Mulberry Cuttings: A Step-by-Step Guide

Mulberry trees can be propagated from dormant hardwood cuttings, actively growing summer cuttings, or by grafting onto an established rootstock. The best choice depends on the cultivar, the time of year, and the growing conditions you can provide. The likelihood of rooting depends greatly by variety.

This detailed guide explains how to root dormant mulberry cuttings like those shipped during our winter cutting sale, what changes when you propagate green summer cuttings, and when grafting may be a better option. The instructions draw on propagation experiments including our published mulberry rooting success-rate records.

Overview: Rooting a Dormant Mulberry Cutting

1. Inspect and label: Confirm that the wood is firm, with healthy buds. Ensure it is labeled.
2. Identify the base: plant the end that was closest to the parent tree downward. Buds on the stem should point up.
3. Prepare a pot: use a tall container with drainage and a lightly damp, well-aerated rooting medium.
4. Prepare the lower end: make a clean basal cut near a node and apply rooting hormone.
5. Manage moisture loss: wrap the exposed wood lightly with Parafilm or use a humidity enclosure.
6. Plant upright: place at least one or two nodes below the medium and leave a healthy bud above it.
7. Give the roots warmth: use controlled bottom heat, generally around 70–80°F (21–27°C) at the rooting medium.
8. Water sparingly: the mix should be evenly damp but never waterlogged. Move the cutting into bright indirect light as shoots develop.
9. Wait for actual roots: leaves alone do not mean the cutting has rooted. Stem growth is a good indicator that roots have formed. Pot up only after a usable root system develops.

For the complete method, continue below. If you are propagating 'green' summer cuttings, skip to the summer-cuttings instructions; dormant-cutting storage and initial darkness do not apply to actively growing leafy wood.

Watch: How We Propagate Mulberry Trees from Cuttings

Our demonstration covers preparing dormant mulberry wood, using pots and a rooting medium, applying rooting hormone, protecting the exposed cutting from drying, and managing warmth and humidity. These are approaches we've used successfully, not a claim that every mulberry cultivar will root at the same rate.

Three Ways to Propagate Mulberries

Method	When it is used	What matters most
Dormant hardwood cuttings	Late fall through winter, after leaves have dropped	Moisture control, an airy rooting medium, warm root zone, patience
Green/softwood cuttings	Active growth in late spring or summer	High but ventilated humidity, retained leaf area, bright indirect light
Grafting	Usually late winter or spring with suitable rootstock and dormant scionwood	Compatible rootstock, cambium contact, careful sealing, aftercare

All three methods can preserve a named cultivar's characteristics when done correctly. Seedlings are different: mulberry seeds may not produce a tree with the same fruit or growth habit as the parent.

1. What to Do When Your Dormant Mulberry Cuttings Arrive

Open the package soon after delivery. Dormant cuttings normally have no leaves; that is expected. Inspect the wood for firmness and sound buds. A cutting can have dry-looking bark without being dead, but a branch that is extremely shriveled, brittle throughout, or soft and rotting should be treated with caution.

If you're ready to propagate, keep the cuttings cool while preparing your supplies. If you need to wait, seal the cuttings in a clean plastic bag with very slightly damp packing material and refrigerate at approximately 37°F (~3°C), safely above freezing. Check periodically for drying, mold, and heavy condensation. Avoid storing them near ripening fruit or allowing them to warm and leaf out before you are ready.

Our winter mulberry cuttings are harvested after dormancy begins and stored at approximately 37°F (3°C). They are generally at least eight inches long, have three or more buds, and are grown on our own farm. Diameter varies, so use the actual cultivar listing for specifications rather than assuming all cuttings are pencil-thick. For details about our harvested material, see About Our Mulberry Cuttings.

2. Supplies for Rooting Dormant Mulberry Cuttings

• Healthy dormant mulberry cuttings, labeled by cultivar
• Clean pruning shears, plant labels, and a marker
• Tall nursery pots (our method often uses nine-inch tree pots) with drainage holes
• A well-aerated rooting mix, such as approximately 75% peat moss and 25% perlite by volume, or a quality peat/perlite propagation mix
• A rooting hormone labeled for woody cuttings (optional, but part of our standard dormant-cutting approach)
• Parafilm or grafting tape, or a humidity tent with some ventilation
• Optional thermostatically controlled heat mat and a probe that measures the medium's temperature
• Bright, indirect light for when active leaf growth begins
• Optional clear-sided propagation pots for observing roots without disturbing the cutting

Use clean pots and fresh medium. A tall pot accommodates a substantial portion of the hardwood cutting below the surface while leaving room for roots to develop. A small container is fine for one cutting; a nine-inch tree pot is useful for the method demonstrated in our video. Whatever pot you choose, drainage is essential.

3. Identify the Bottom and Prepare the Cutting

Look closely at the buds: they normally point toward the tip of the branch, and their orientation can help you distinguish top from bottom. If the cutting has marked ends, follow that identification. The basal end—the end that was nearer the trunk—goes downward into the rooting medium.

1. Keep the cultivar label with the cutting. Several mulberry varieties can look nearly identical while dormant.
2. If the base is damaged or dried out, make one fresh, clean cut near a healthy node. Some growers lightly wound the base to expose a narrow strip of cambium, but this is not required for every cutting. 
3. Leave multiple healthy buds on the cutting. A three-bud cutting is a useful standard; longer supplied cuttings may have more.
4. If using rooting hormone, apply it only to the lower end, following the manufacturer's concentration and handling instructions.
5. Optionally wrap the upper exposed portion with Parafilm, avoiding unnecessary damage to the buds.

4. Prepare the Rooting Medium

We have used commercial Pro-Mix and a homemade mix of approximately three parts peat moss to one part perlite. Alternatives with similar drainage and moisture properties may work, but avoid heavy garden soil in small rooting pots.

Moisten the mix before filling the pots. A good practical test: squeeze a handful. It should feel damp and hold together loosely, but water should not drip out. If it is dripping, let it drain or mix in additional dry medium. Fill pots gently; don't compact the mix into a dense, airless block.

When mulberry cuttings have no roots and no leaves, they use very little water. Overwatering is one of the easiest ways to lose otherwise healthy wood. The goal is consistent light moisture plus oxygen, not saturation.

5. Plant the Cutting and Protect It from Drying Out

1. Make a hole with a dibber or pencil to avoid wiping off the rooting hormone.
2. Insert the cutting with its basal end down. Place at least one or two nodes below the surface and leave one or more good buds above the medium.
3. Firm the medium gently around the wood so the cutting does not wobble.
4. Water lightly to settle the medium, then let all excess water drain.
5. Place the pot where temperatures can be controlled. Use Parafilm on the exposed stem or a humidity enclosure to limit moisture loss.

Our videos sometimes show two or three cuttings in one pot to conserve space. That can work, but the roots may become intertwined. For first-time growers, one cutting per container is simpler, especially when it comes time to pot up or identify a failure.

6. Manage Bottom Heat, Humidity, and Light

We commonly place dormant, leafless mulberry cuttings on bottom heat near 80°F (27°C). For a home setup, a controlled root-zone range around 70–80°F (21–27°C) is a reasonable starting point. The temperature of the rooting medium matters more than the number printed on a heat mat; use a thermostat and avoid overheating roots.

Our earlier dormant-cutting trials included an initial period in darkness—often around two weeks—before moving the pots into light. This is an optional feature of a method we tested, not a universal requirement. Darkness should not be continued after shoots are actively unfolding leaves, or new growth can become pale and weak. Once buds have expanded, provide bright indirect light, good ventilation, and protection from sudden intense sun.

High humidity can protect an emerging shoot that has little root support. But a sealed, overheated chamber also promotes mold, rot, and weak growth. If you use a clear cover, monitor condensation, vent it as necessary, and keep it out of direct sun. Parafilm around a dormant stem can reduce moisture loss without covering the whole pot.

Check the medium itself before watering. It may take a week or longer to need additional water, depending on pot size and conditions. In our trials we sometimes bottom-water lightly after a couple of weeks. If using that method, allow brief absorption and then empty the tray; never leave a rooting pot continuously standing in water.

7. How Long Do Mulberry Cuttings Take to Root?

Mulberry roots can begin forming within several weeks, but difficult varieties and cooler or less consistent conditions can take considerably longer. A practical check-in window is four to eight weeks, sometimes much longer. Do not decide that a cutting has failed simply because it has not leafed out on a fixed calendar date.

A cutting may push buds using energy stored in its wood before it grows functional roots. That is why leaves by themselves are not proof of success. Better indicators include visible pale roots at the container wall or drainage hole, a gentle increase in stability, and continued healthy shoot growth after the initial flush.

A swollen, pale callus at the base is a healing response and can be encouraging, but it is not yet a root system. Repeatedly pulling the cutting out to inspect it can destroy young root initials. Resist the temptation to check every few days.

8. What Our Mulberry Rooting Trials Teach Us

We've rooted many mulberry cultivars at Dingdong's Garden and recorded both successes and failures. In the mulberry rooting results updated October 14, 2026, some varieties performed very well in our particular trials: for example, Buluklu rooted in 8 of 8 attempts, Issai Dwarf in 19 of 20, and Maple Leaf in 18 of 19. Those are small, observational batches, not statistically reliable guarantees or rankings for all gardens.

Other mulberry types have been challenging in different years, even when handled in a similar way. Changing the humidity, length of the initial warm/dark stage, age of the wood, hormone treatment, or timing can affect results. We also tested larger second-year dormant wood: in one 2026 trial, 36 cuttings were assessed after six weeks and approximately 67% had rooted in the reported conditions. That trial shows older wood can be viable; it does not establish that second-year wood is superior to first-year wood across cultivars.

The practical lesson is to look up results for your specific variety when available, root more than one cutting if possible, and keep notes on your own growing conditions. Our data reflects our farm and experiments—not a controlled laboratory comparison or a prediction of an individual customer's outcome.

9. Pot Up Your Rooted Mulberry Cutting Without Damaging It

Wait for multiple well-developed roots before moving your young tree to a larger pot. When the roots begin holding the medium together, transfer the cutting carefully into fresh, well-drained potting soil. Do not up-pot on leaf growth alone.

1. Lightly moisten the original pot so the root ball slides out together.
2. Prepare a slightly larger pot; don't place a tiny root system into a very large container that stays wet.
3. Gently tip or slide out the entire root ball, supporting it from below rather than pulling on the trunk.
4. Keep roughly the same planting depth and settle fresh potting mix around the root ball.
5. Water once to settle the potting mix, allow excess water to drain, and protect the young plant from strong sun and wind for several days.

If you started several cuttings in the same pot, their roots may be entangled. Separating them too soon can damage all of them. It is often better to keep the root ball intact until a safer separation is possible. For a demonstration with rooted Valdosta and Callie's Delight trees, see How to Pot-Up Rooted Mulberry Cuttings.

10. Harden Off and Grow the Young Tree

Newly rooted cuttings grown indoors are vulnerable to sunscald, wind, water stress, and frost. Once the root system is established and outdoor temperatures are suitable, expose the plant gradually to outdoor conditions over about 7–14 days. Start in sheltered shade, then increase morning sun and air movement in stages. Bring it inside or protect it whenever freezing temperatures threaten.

Mulberries generally prefer a sunny growing location with good drainage, but their cold hardiness, mature size, and suitability for containers vary by species and cultivar. Select a planting site only after checking your particular tree's requirements and local conditions. Our mother plants grow on Lopez Island in the maritime Pacific Northwest; that is not proof that each cultivar will perform the same way elsewhere.

Begin modest feeding only once roots and new growth are established. For a newly rooted plant, steady moisture, drainage, and gradual acclimation matter more than vigorous fertilization.

Rooting Green Mulberry Cuttings in Summer

Summer greenwood or softwood cuttings are not handled like dormant sticks. They can carry actively growing leaves, which can help fuel root formation but also lose water rapidly. We have tested summer propagation using humidity tents and compared results among multiple cultivars. Our summer-cuttings experiment reports differing results by variety, with several early success rates in the approximate 33–61% range after one month. These figures belong to those batches and observation dates, not every mulberry cutting.

1. Choose suitable growth: take healthy current-season shoots that are not wilted or badly stressed, preferably in the cooler part of the day. Avoid wood that is flowering, fruiting heavily, or visibly diseased.
2. Prevent drying immediately: keep material shaded and slightly humid while preparing it. Plant as promptly as practical; do not put leafy wood into the refrigerator for long-term dormant storage.
3. Prepare the stem: use clean tools, remove leaves that would be buried, and retain a small amount of healthy foliage like one half of one leaf. If leaves are large, reducing some leaf area can limit transpiration without removing all the photosynthetic surface.
4. Use an airy medium: insert the lower portion into premoistened peat/perlite or an equivalent propagation mix. Rooting hormone is optional; follow label directions if used.
5. Maintain humidity with airflow: a tent, dome, or clean loose cover helps leaves stay hydrated, but it must not overheat and should be ventilated to limit fungal problems.
6. Provide bright indirect light: leafy summer cuttings need light; do not place them in darkness for weeks as you might with a leafless dormant-cutting trial.
7. Check for roots gently: observe the pot edges or drainage holes and wait for sufficient development before transplanting.

Because evaporation is so much faster from summer leaves, the ideal setup differs from winter hardwood rooting. For growers who have struggled with dormant wood from a particular cultivar, comparing summer cuttings can be worthwhile.

When Is Grafting a Better Choice?

If a cultivar consistently resists rooting, you may be able to propagate it by grafting dormant scionwood onto a compatible, healthy mulberry rootstock. Grafting joins a desired variety (the scion) with a root system that is already established; unlike rooting, it does not depend on the scion forming its own roots.

The basic steps are to obtain a compatible rootstock, keep suitable scionwood dormant until the correct grafting window, make matching cuts with clean sharp tools, align cambium layers, and wrap and seal the graft to prevent drying. The exact method—such as whip-and-tongue, cleft grafting, or budding—depends on scion and rootstock size, timing, and the grower's skill. Not every mulberry species and rootstock combination is reliably compatible, so verify compatibility before cutting.

The dormant mulberry material we sell can sometimes be used for grafting as well as rooting, but diameters vary. Check the individual product listing or contact us if your graft requires a particular scion size. For detailed, variety-specific propagation information, see our mulberry cutting specifications and the mulberry collection.

Troubleshooting Mulberry Cutting Problems

My cutting has leaves but no roots. Is it established?

Not necessarily. Stored energy in dormant wood can produce leaves before roots grow. Reduce drying stress, check medium moisture, provide bright indirect light for green shoots, and wait for convincing root development before transplanting. Stem development often indicate that rooting has started.

The cutting is turning black or soft at the base.

Rot is often associated with overly wet or poorly aerated media, though damaged wood can arrive with problems already developing. Inspect drainage, avoid standing water, and isolate failing material. A stem that is fully soft and decomposing may not be salvageable.

White fuzz or mold is growing on the cutting.

Persistent condensation, stagnant air, and overly wet surfaces encourage fungal growth. Ventilate covers, remove obviously moldy debris, and reduce excess moisture. Minor surface mold does not automatically prove the entire cutting is dead, but mold combined with deep soft rot is a warning sign.

The cutting shrivels, or the new leaves wilt.

The roots may not be sufficient to replace water lost through leaves. Check moisture at root depth and avoid strong sunlight. A modest, vented humidity cover can help in the short term. Don't automatically saturate the mix: root rot can also cause wilting.

Nothing has happened after a month.

Some cultivars are slower or harder to root. Confirm the root-zone temperature, media moisture, and cutting health, but avoid digging out the cutting. Mulberries are not on a single four-week schedule.

Roots formed, then the plant died after transplanting.

Young roots can be easily torn or dried during potting up. Transfer the root ball intact, use only a moderately larger pot, and keep the plant in sheltered indirect light while it recovers. Harden off gradually before moving outdoors.

Frequently Asked Questions About Mulberry Propagation

Can mulberry trees really grow from cuttings?

Yes. Many mulberries can be propagated from hardwood or softwood stem cuttings, though success varies considerably by species, cultivar, and method. Rooted cuttings preserve the parent plant's cultivar identity.

Are dormant cuttings or summer green cuttings better?

Neither is best for every variety. Dormant wood is convenient for winter harvesting and shipping and can be rooted with controlled bottom heat. Summer leafy cuttings can work well for certain cultivars when humidity and light are managed carefully. Comparing the two methods for a difficult cultivar may be useful.

Can I root mulberry cuttings in water?

Some mulberry cuttings can initiate roots in water, but results are inconsistent and the roots can be vulnerable when transferred into soil. We prefer an airy rooting medium that supports root development directly in a container.

Should mulberry cuttings be kept in the dark?

We have used an initial dark period for leafless dormant cuttings during some experiments. It is not essential for every setup. Growing leaves need light, and leafy summer cuttings should be kept in bright indirect light rather than darkness.

What temperature is best for rooting mulberry cuttings?

Our dormant-cutting setup often targets bottom heat near 80°F (27°C). For a home grower, controlled rooting-medium warmth in roughly the 70–80°F range can be a useful starting point. Avoid unregulated heat or overheating under plastic covers.

Do I have to use rooting hormone?

No, but we often use it for dormant mulberry cuttings. We have also tested methods without hormone, and the outcome depends on more than that single variable. Correct moisture, healthy wood, root-zone temperature, and cultivar are important too.

How deep should I plant a mulberry cutting?

Plant the basal end downward with one or two nodes below the medium and at least one sound bud remaining above it. The exact depth depends on cutting length and pot size. Do not bury every viable bud or leave the stem so shallow that it tips over.

When can a rooted mulberry cutting go outdoors?

Once it has a functioning root system, is growing steadily, and the weather is suitable. Acclimate it gradually to wind and sunlight over about one to two weeks, and protect young plants from frost.

Will a rooted mulberry cutting produce the same fruit as the original tree?

Yes, a successfully rooted cutting is a vegetative clone of its parent cultivar. Fruit quality and productivity still depend on growing conditions, maturity, health, and any pollination requirements of that plant.

What if my mulberry variety is difficult to root?

Check our cultivar-specific rooting observations, consider a summer-cutting method where appropriate, or investigate grafting onto a compatible rootstock. Avoid relying on a single cutting or assuming that results from one cultivar apply to all mulberries.

The key to rooting mulberries is not a secret ingredient: start with viable wood, keep the root zone warm but aerated, manage moisture carefully, protect emerging growth from drying, and give each variety time. Because mulberry rooting behavior differs so much from cultivar to cultivar, keeping your own records can be as useful as following a propagation recipe.
