How to propagate Spider plant (Chlorophytum comosum) — step by step

Also called airplane plant, ribbon plant, spider ivy.

The best way to propagate spider plant

The reliable, beginner-friendly way to propagate spider plant is rooting the plantlets it sends out on runners. It suits this species because of how it grows: clumping evergreen that produces dangling plantlets. Snip a plantlet from a runner and root in water for 1-2 weeks before potting up.

For the wider picture of which technique suits which plant, our guide to plant propagation methods compares water, soil, leaf, division and offset propagation side by side.

Step-by-step: propagating spider plant

Pick a plantlet. Choose a spider plant plantlet (one of the babies on a runner) that already shows little nubby aerial roots at its base.
Choose attached or detached. Easiest: pin the still-attached plantlet onto a pot of moist soil beside the mother and let it root before you sever the runner.
Or root in water. Alternatively snip the plantlet off, sit just its base in water (leaves above the surface) and wait for roots to lengthen.
Pot it up. Once roots are 2–3 cm — about 1–2 weeks — pot into standard mix and cut the umbilical runner if you used the attached method.
Or divide. A crowded spider plant can also be tipped out and pulled into several rooted clumps for instant new plants.

The alternative method

If the main route does not suit your plant or setup, division of a crowded mother plant is the next best option for spider plant. Tip a congested mother out of its pot and pull or cut it into several rooted clumps — instant full plants, useful when you want size now rather than waiting on plantlets.

Timeline to roots

Realistically: roots in 1–2 weeks once the plantlet is potted. These numbers assume spring or summer warmth and bright indirect light. In a cold, dark room — or in winter dormancy — the same spider plant propagation can take twice as long or stall completely, so do not panic if progress looks slow out of season. Patience beats poking: disturbing a forming root system to “check” on it is a common way to set it back.

Common failure points

Detaching a plantlet with no aerial-root nubs yet — give it longer on the mother first.
Submerging the whole plantlet in water so the crown rots — only the base goes in.
Letting a freshly potted plantlet dry out before its roots establish.
Propagating off a stressed, pest-ridden or recently-repotted spider plant — always take material from a healthy, established parent.

When to do it

The best window is spring and summer. Propagation is energetically expensive for a plant, and it only has the spare resources to build new roots when it is already growing actively, warm and well-lit. Out-of-season attempts are not pointless, but expect lower success and a longer wait.

Aftercare

A rooted spider plant plantlet establishes quickly — keep the mix lightly moist and bright for the first couple of weeks, then move to the normal routine. If you rooted it while attached to the mother, only cut the runner once the baby is clearly growing on its own. Match the parent's needs as the new spider plant settles: Medium to bright indirect light. Direct sun bleaches leaves; deep shade slows growth.

Spider plant propagation — frequently asked questions

What is the best way to propagate spider plant?

Rooting the plantlets it sends out on runners is the most reliable method for spider plant. Propagate spider plant from the plantlets it sends out on runners. Root a plantlet that already has nubby aerial roots in water or pin it onto soil while still attached to the mother. It roots in 1–2 weeks. Division of a crowded clump also works.

Do you need a node to propagate spider plant?

For spider plant the rooting structure is rooting the plantlets it sends out on runners, so a classic "node" matters less than starting with the right plant material — Root a plantlet that already has nubby aerial roots in water or pin it onto soil while still attached to the mother.

How long does it take spider plant to root?

Roots in 1–2 weeks once the plantlet is potted. Timing varies with warmth and light — propagations move fastest in spring and summer when the plant is in active growth, and can stall almost completely in a cold, dark winter.

What is the best time of year to propagate spider plant?

Spring and summer. Root and shoot development is metabolically demanding, so propagating during the active growing season gives noticeably higher success rates and faster results than attempting it in dormancy.

Can you propagate spider plant in water?

Yes — sit just the base of a spider plant plantlet in water (keep the leaves above the surface) and it roots within a week or two. Rooting it directly in soil, or while still attached to the mother, is just as effective.
