Propagating houseplants: stem and leaf cuttings, division and layering

What you get from a cutting

Taking a cutting means removing a piece of a plant (stem, leaf, or root) and placing it where it can grow new roots or shoots. The young plant you end up with is a clone: it carries exactly the traits of the parent, which seeds cannot guarantee.

Not every plant suits every method. Some lack the structures needed to regrow from a cutting and are better propagated by division. A large plant that needs pruning, on the other hand, makes an excellent candidate.

Early spring is the ideal time, as the plant moves into active growth. That said, most houseplants can also be propagated in other seasons. In either hemisphere, go by the return of new growth rather than the calendar.

Matching the method to the plant

Method	Suitable plants	What grows back
Stem cutting	Pothos, heartleaf philodendron, zebra plant, English ivy, monstera	Roots at the buried nodes
Leaf-petiole cutting	African violet, peperomia, jade plant, ZZ plant	Small plantlets at the base of the leaf stalk
Leaf section	Snake plant, Cape primrose, rex begonias	Shoots at the base of each section
Whole succulent leaf	Mexican snowball, jade plant, burro’s tail	Roots and a rosette where the leaf was attached
Division	Snake plant, ZZ plant, spider plant, peace lily, ferns, aloes	Each piece already has roots
Air layering	Rubber plant, weeping fig, corn plant, dumb cane	Roots on a stem still attached to the parent

Always choose vigorous, healthy shoots: weak, diseased, or pest-damaged material roots poorly.

Stem cuttings, step by step

1. Cut a stem tip 3–6 in long with at least two nodes, the slightly swollen points where leaves attach. Use a sharp knife: a dull blade crushes the tissue and limits water uptake.
2. Prepare the cutting: strip the lower leaves along with any flowers or fruit. If the remaining leaves are very large, trim them to reduce water loss.
3. Rooting hormone is optional: houseplants usually do not need it. If you use it, follow the label, pour a little into a separate container instead of dipping the cutting into the original package, and do not overapply.
4. Prepare the medium: perlite, sand, vermiculite, sphagnum moss, peat moss, or a mix (sand and peat, perlite and peat). Potting soil on its own is a poor choice; use it only as part of a mix. Pick a clean container with drainage holes, at least 2 in deep, and moisten the medium before planting.
5. Plant: make a hole with a pencil or chopstick, insert the cutting so at least one node is buried and no leaves touch the medium, then water and let it drain.
6. Hold in humidity: without roots, a cutting cannot replace the water it loses. Cover it with a clear plastic bag or dome held off the leaves with chopsticks or wire loops, without sealing it tight. Let in fresh air now and then.
7. Find the right spot: four to six hours of bright, indirect light, out of direct sun, which would overheat the inside of the cover. Air between 64–75 °F is ideal; a heat mat can bring the medium up to 75–81 °F.

Most stem cuttings root in three to six weeks. To check, tug very gently on the stem: resistance means roots have formed.

Water or rooting medium?

Many houseplants root in nothing more than a jar of water, like the pothos cutting in the photo. A few rules:

• change the water once or twice a week;
• keep the level high enough to cover the developing roots;
• move the cutting to a pot once the roots reach about 1 in: left in water after rooting, it can rot.

Roots that form in water are coarser than those grown in a medium, and the plant can struggle for a while after potting. Succulents, by contrast, root poorly in water: start them directly in a well-drained mix.

Leaf cuttings

These work only with plants that can form new buds from leaf tissue, since a leaf on its own has no bud at its base. Choose young but fully grown leaves that are healthy and undamaged.

• Leaf-petiole cuttings (African violet, peperomia, ZZ plant, jade plant): keep 1–2 in of leaf stalk, or as much as there is if it is shorter. Insert it at roughly a 45-degree angle into the moist medium and cover with an unsealed bag. Roots appear in three to four weeks and plantlets in six to eight weeks. Separate them when you pot them up.
• Snake plant sections: cut the leaf into pieces 3–4 in tall and bury them 1–2 in deep, with the end that was closest to the base pointing down. A small notch at the top of each piece prevents mix-ups, because new growth forms only at the bottom end. Allow about two months for the first shoots. Note that a variegated snake plant with yellow edges loses them when grown from leaf sections; divide the clump instead to keep them.
• Cape primrose: halve a full-grown leaf along the midrib, discard the midrib, then set the cut edge into a shallow trench and firm it in.
• Succulents (Mexican snowball, jade plant, burro’s tail): remove the whole leaf, including the tissue that attached it to the stem; part of a leaf will not root. Let the cut callus for a day or two, then lay the leaf on a barely damp, well-drained mix, uncovered, in a warm, bright spot. Mist the surface so it stays slightly damp, never soggy. Roots and a rosette form within a few weeks.

Division, plantlets, and layering

Division is one of the quickest methods. Remove the plant from its pot, lay the root ball on its side, and tease it apart by hand; if it is too tight, cut through it with a knife. Each piece needs healthy leaves, stems, and roots. Larger pieces recover faster, while smaller ones give you more plants. Replant them in fresh potting mix, often in a pot smaller than the original, water to settle the soil, and place them in bright, indirect light. For tips on getting a plant out of its pot, see Repotting a houseplant.

Spider plant plantlets can simply be cut from the parent and potted.

Air layering suits plants with stiff stems such as the rubber plant. About 12–18 in from the tip, remove the leaves, then strip off a ring of bark about 1 in wide (on dracaenas and dumb canes, make an upward slanting cut a third of the way through the stem instead, held open with a toothpick). Dust with rooting hormone, wrap with moist sphagnum moss, cover with clear plastic, and tie off both ends. Once plenty of roots show through the moss, cut below the wrap and pot the new plant. Expect several weeks, sometimes several months.

Simple layering suits long, flexible stems (pothos, English ivy, heartleaf philodendron): bend a stem into a neighboring pot, bury at least one node, pin it down, and cut it from the parent once it is well rooted, usually after six to twelve weeks.

After rooting

When the roots are about 1 in long, move the young plant into regular potting mix in a pot that suits its size. Keep it in bright, indirect light and well watered, checking the mix rather than following a fixed routine: see Watering by observation. It settles in within a few weeks; you can then move it to its permanent spot and start feeding it, as explained in Fertilizing houseplants.

Common mistakes and signs to watch

A cutting that fails to take can have more than one cause; look at all the conditions before drawing conclusions.

• Black, mushy base: the medium is too wet. Water sparingly, air out the cover about twice a week, and promptly remove any rotting leaves to limit gray mold.
• Nothing happens: rooting slows down a lot at low temperatures. Aim for about 68 °F.
• Pale, stretched shoots: there is not enough light. Move the cutting closer to a bright window, out of direct sun; see Reading indoor light.
• Cutting wilting under its cover: the cover could be sitting in full sun, where it overheats, or be sealed too tightly.
• Rotting succulent: the cut did not callus enough, or the mix is too wet.
• Tiny insects: watch for aphids, whiteflies, and mealybugs.

What about bonsai?

Cuttings are also a classic, inexpensive way to grow future bonsai. They save about a year compared with starting from seed. Most trees, especially deciduous trees and some conifers, propagate easily from cuttings in spring and summer.

Choose twigs 2–4 in long and 0–0 in thick: larger cuttings root less reliably, and air layering suits them better. Cut at roughly a 45-degree angle with sharp twig shears. Put a coarse, draining layer (lava rock or grit) in the bottom of the pot, add bonsai soil, insert each cutting about 1 in deep, water thoroughly, and keep the soil slightly moist. New growth appears within a few weeks, but it takes a few years before you can start shaping the tree. From there, turn to the guide for each species, such as the one for Ficus microcarpa.
