Propagating a pothos in water: the foolproof method

The pothos is probably the easiest plant to multiply in the world. Its ability to produce roots in days in a simple glass of water makes it the ideal candidate for anyone wanting to learn propagation, multiply their plant, or give a personal gift to friends. The method is so reliable that the success rate is around 95 percent for beginners.

Why the pothos roots so fast

The pothos is a vine that, in the wild, climbs trunks by gripping with its aerial roots. The small brown protrusions you see on stems at the nodes are not an aesthetic flaw: they are roots waiting. In contact with humid soil or water, they extend and dive to seek water and nutrients.

This adaptation explains why a simple cutting in water starts producing roots in just 7 days.

Identify the right cut locations

Before cutting, locate the nodes on the stem. The node is the slightly raised area where a leaf emerges and a small brown aerial root sticks out. This is the key spot: that is where new roots will sprout.

A good cutting includes at least one node, ideally two or three for better chances. The longer the stem portion included, the more energy reserves the cutting has to start.

Step-by-step method

Step 1, choose a healthy stem

Select a vigorous pothos stem with well-colored, firm leaves. Avoid yellowing stems or those with damaged leaves. A stem with 4 to 8 leaves is perfect.

Step 2, cut below a node

With a clean shear or scissors (blade disinfected with alcohol if possible), cut the stem just below a node. The cut should be clean, not crushed. Count 2 to 5 cm of stem below the lowest node: this portion will be submerged in water.

If you have taken a long stem with several nodes, you can section it into several cuttings, always keeping a minimum of one node per section.

Step 3, remove submerged leaves

On the stem portion that will be in water, gently remove the leaves. Keeping leaves submerged makes them rot and contaminates the water.

You must see at least the lower node(s) bare, ready to be plunged.

Step 4, place in a glass of water

Fill a transparent glass (to track visual progress) with tap water that has rested 24 hours. Plunge the cutting so that the bare nodes are well submerged but remaining leaves are above the surface.

Place the glass in a bright spot without direct sun. Bright indirect light is ideal, like near an east window with sheer curtain.

Step 5, wait 7 to 21 days

That is all. No rooting hormone, no special care. Change the water every 5 to 7 days to prevent stagnation. First white roots usually appear in the first to second week, sprouting directly from the nodes.

Step 6, plant when roots are 3 to 5 cm

Once roots are well formed (3 to 5 cm long, multiple roots per node), you can transplant to soil. Prepare a pot with airy substrate (potting soil + perlite + pine bark), make a hole, gently place the cutting with roots immersed, fill with substrate and lightly tamp.

Water generously the first time to settle the roots in the new substrate. Then resume normal rhythm with the finger method.

Alternative: direct soil propagation

If you prefer to skip the water step, plant the cutting directly in moist substrate. Success rate is slightly lower (80 percent instead of 95) and you cannot visually track root formation.

Prepare a small pot with airy moist substrate. Plant the cutting burying the nodes. Cover with a transparent plastic bag or dome to maintain high humidity. Place in bright indirect light. After 3 to 4 weeks, gently pull the cutting: if it resists, roots have taken.

Mistakes to avoid

A few classic pitfalls. Cutting a stem with no node, or cutting too far from the node (roots only emerge at nodes). Keeping leaves submerged (they rot). Placing the cutting in direct sun or too dark. Forgetting to change water regularly. Transplanting too early before roots reach 3 cm. Tamping the substrate too much at transplant, which suffocates young roots.

What to do with multiple cuttings

From a single vigorous pothos, you can easily get 5 to 10 viable cuttings. Options: grow a new plant in its dedicated pot, replant several cuttings together in the mother pot to bush it up, give to friends (excellent personal gift), create a wall hanging with several trailing vines.
