Water propagation: 20 houseplants that are easy to multiply

Daniel Platteau Articles indoor plant gardening tips

Why water propagation suits houseplants so well

Water propagation is a method of vegetative propagation that involves taking part of a plant — usually a piece of stem — and placing it in water so that it grows roots before being potted into a growing medium (sources 1 and 2).

For houseplants, this technique is popular because it is:

• Simple: it needs little equipment and suits many herbaceous plants.
• Visual: you can watch the roots form.
• Practical: several soft-stemmed tropical plants, such as pothos, philodendron, tradescantia and some monsteras, root easily in water (sources 1 and 3).

It is not, however, always more effective than rooting in compost: some plants root better directly in a moist, airy mix. Roots formed in water then have to adapt to a different medium when potted into compost, which can temporarily slow growth (sources 2 and 4).

How does water propagation work?

Water propagation relies on the ability of some plants to form adventitious roots, that is, roots that appear on a part of the plant other than the main root. In many houseplants, they develop at the nodes, the points on the stem where leaves or side shoots are attached (sources 1 and 3).

General steps

1. Choose a healthy stem

   Select a vigorous stem with no spots, pests or signs of rot. Non-flowering, actively growing stems are generally best (sources 1 and 5).

2. Cut below a node

   The node is the point on the stem where a leaf, a side shoot or sometimes an aerial root grows. Cut just below a node with a clean, sharp tool.

3. Prepare the cutting

   A cutting of 8 to 15 cm is often convenient, but the length depends on the species and the number of nodes available. Remove any leaves that would be under water and keep two or three leaves at the top. These figures are a guide: having a node and a healthy cutting matters more.

4. Put the cutting in water

   Use a clean glass or jar. At least one node must be under water, while the leaves stay above the waterline.

5. Choose the spot

   Place the container somewhere bright but out of direct sun. A normal, steady and mild room temperature suits most species.

6. Look after the water

   Change the water when it becomes cloudy or, as a precaution, every three to five days. Use a clean container and make sure no leaves are sitting in the water. A piece of charcoal is not essential and does not replace cleaning the container or changing the water.

7. Wait for roots, then pot up

   The time varies greatly with species, season, temperature, light and the condition of the cutting: some cuttings produce roots within a week, others take several weeks. Pot up when the cutting has several healthy roots and shows steady growth, rather than relying on a precise root length.

Advantages and limits of water propagation

Advantages

• Accessible: it needs little equipment.
• Observable: you can see the roots forming.
• Good success rate for several tropical houseplants: pothos, tradescantia, philodendrons, syngonium, spider plant…
• Educational: it makes one stage of vegetative propagation easy to observe.

Drawbacks and points to watch

• Roots formed in water are adapted to a very wet environment and may react badly to being moved abruptly into dry or very free-draining compost. A gradual transition is better (sources 2 and 4).
• Submerged leaves and stagnant water encourage the cutting to rot.
• Full sun heats the container, stresses the cutting and encourages algae.
• Not all plants root well in water. Woody plants, cacti and many succulents are better propagated by other methods or in a suitable growing medium.

Rooting in compost is not necessarily "better": it mainly avoids a transition step when the plant is meant to grow in compost.

20 houseplants that are easy to propagate in water

How easily a plant roots depends on the species, cultivar, season and whether there is a viable node. The list below is a practical selection, not a guaranteed ranking.

1. Pothos (Epipremnum aureum)

Pothos is one of the easiest houseplants to propagate from stem cuttings. Take a piece with at least one node and put the node under water without submerging the leaves. Roots often appear within one to three weeks.

Beware of a common mix-up in the trade: "scindapsus" (Scindapsus pictus) is a different species, even though it is propagated the same way.

2. Tradescantia (inch plant)

The stems of many Tradescantia species readily produce roots at the nodes. The cuttings can then be grouped in a single pot for a fuller clump.

3. Monstera adansonii and other monsteras

Monsteras can be propagated from stem cuttings as long as the piece has a node. An aerial root may be present, but it is not essential.

A leaf on its own or a leaf stalk without a node will not produce a new shoot: it is the node that carries the growing point needed to form a new stem (source 3).

4. Climbing philodendrons

Climbing philodendrons, particularly the heartleaf philodendron, often root easily from cuttings with a node, usually within two to three weeks.

5. Aglaonema

Aglaonema can be propagated by stem cuttings or by division, depending on the species and the plant's structure. The pieces must be healthy and the water very clean.

6. Cane begonias

Many cane-stemmed begonias ("angel wing" begonias) can be propagated from stem sections. Rhizomatous and tuberous begonias are treated differently.

7. Coleus (Plectranthus scutellarioides)

The botanical name commonly used today for coleus is Plectranthus scutellarioides; Solenostemon is an older name still often seen. Its soft stems usually root very easily in water.

8. Fittonia

Fittonia can be propagated by stem cuttings, but its thin pieces are prone to drying out. Indirect light and steady humidity are recommended.

9. Syngonium

Syngonium cuttings must have at least one node. They can be placed in clean water, in indirect light.

10. Papyrus

Papyrus is propagated mainly by division, or by turning a leafy head upside down in water, from which new shoots will grow: this is not a stem cutting like a pothos.

11. Peperomia

Some Peperomia species can be propagated by stem or leaf cuttings. Success depends on the species; leaf cuttings often take better in moist compost than in water.

12. Pilea

Pilea peperomioides is propagated mainly from its offsets. An offset can be placed in water if it has a viable base, but potting it directly works very well too.

13. Hypoestes (polka dot plant)

Hypoestes can be propagated by stem cuttings. Choose young, healthy pieces and protect them from drying out.

14. Ceropegia woodii, or string of hearts

Water propagation can work, but string-of-hearts cuttings often do better laid on a very free-draining mix.

15. Chlorophytum, or spider plant

The plantlets that form at the end of the flower stems can be placed in water to grow roots before potting (source 1). These are already-formed plantlets rather than a classic stem cutting.

16. Ivy (Hedera)

Ivy roots easily from stem sections, but rooting directly in moist compost is just as common.

17. Fuchsia

Fuchsias are propagated from softwood or semi-ripe stem cuttings. They are not houseplants in the strict sense, but pot or conservatory plants that can be overwintered indoors.

18. Impatiens

Impatiens root very easily from stem cuttings. Indirect light and clean water limit the risk of rot.

19. Dracaena

Dracaena is propagated from tip cuttings or stem sections. Cane cuttings take longer than soft cuttings.

20. Dieffenbachia

Dieffenbachia is propagated from stem sections, but its sap contains insoluble calcium oxalate crystals that irritate the mouth and throat if chewed or swallowed (source 6). Wear gloves.

Other plants could complete this list: mint, basil, or some shrubs such as Mexican orange blossom (Choisya).

Getting water cuttings right: a detailed guide

Choosing the right plants and the right time

Favour plants with soft stems and visible nodes. Spring and early summer are the best times, as growth is active, but many houseplants can be propagated at other times if they get enough light and warmth (sources 1 and 5).

The time of day matters little compared with how well watered the plant is, how clean the tool is and the rooting conditions.

Preparing the cutting

1. Take a healthy stem with at least one node.
2. Cut cleanly below the node with a disinfected tool.
3. Remove any leaves that would be under water.
4. Remove any flowers and buds, so that the cutting puts its resources into rooting (sources 1 and 5).

Putting it in water

Use a clean container and room-temperature water. Tap water is fine in most cases; rainwater or filtered water can be used if your water is very hard.

Place the container somewhere bright, out of direct sun. The water level should cover the node or nodes without submerging the leaves.

Follow-up, care and potting up

Change the water every three to five days, or sooner if it turns cloudy. Clean the container if a slimy film or bad smell appears (sources 1 and 2).

Healthy roots are firm; their colour, often white, varies with the species.

Once several roots have formed, pot the cutting into a small pot with drainage holes, filled with a light, slightly moist mix. Avoid going straight from a container of water to very dry compost.

A small pot makes moisture easier to manage, but is not enough on its own to prevent overwatering: drainage, the growing medium and watering frequency remain decisive.

Water cuttings, plant health and risks to know about

1. Potentially toxic plants

Some houseplants contain insoluble calcium oxalate crystals: this is notably the case for pothos, philodendron, dieffenbachia and aglaonema (source 6). If chewed, they can cause mouth irritation, excessive drooling, vomiting or difficulty swallowing, in children as well as animals; the effects depend on the plant and the amount.

Toxicity mainly concerns ingestion or contact with the sap; the water in a propagation container is not necessarily dangerous, but it should be kept out of reach of children and pets.

• Wear gloves if you have sensitive skin or if the plant's sap is irritant.
• Wash your hands after handling.
• Do not leave cuttings, cut leaves or container water within reach of children and pets.
• In case of ingestion, contact a doctor, a poison centre (in Belgium: 070 245 245; elsewhere, your local poison control centre) or a vet, as appropriate.

2. Stagnant water and rot

Cloudy water, an unpleasant smell or a slimy base mean you should take the cutting out, cut off damaged tissue, clean the container and change the water. Changing the water regularly remains the best prevention (sources 1 and 2).

3. Potting-up stress

Roots formed in water must adapt to compost. After potting up, keep the compost slightly moist without soaking it, and place the plant in indirect light. A temporary slowdown in growth is normal.

Water or soil: when to choose which?

Rooting in water

This method is particularly suitable:

• for houseplants with soft stems and visible nodes;
• for pothos, tradescantias, philodendrons, syngoniums and monsteras;
• when you want to watch the roots form.

Rooting directly in compost

Rooting in compost is better:

• for woody plants;
• for cacti and many succulents;
• when the roots need to be adapted to pot culture from the start;
• for species that rot easily in water.

Neither method is always superior: the choice depends on the species, the type of cutting, the season and the conditions available.

Practical tips for turning your cuttings into an indoor jungle

• Take several cuttings at once to improve your chances of success.
• Label the containers if you are testing several species or cultivars.
• Use clean containers and do not group cuttings showing signs of disease.
• Pot up cuttings once they have several healthy roots.
• Give rooted cuttings away in a small pot, with the plant's name and, where relevant, a toxicity warning.
• For a decorative nursery, use clear jars, but keep them out of direct sun and clean them regularly.
