How to propagate Creeping Charlie (Glechoma hederacea) — step by step

Also called Creeping Charlie, Ground Ivy, Gill-over-the-Ground, Runaway Robin, Field Balm.

The best way to propagate creeping charlie

The reliable, beginner-friendly way to propagate creeping charlie is softwood tip cuttings in water or soil. It suits this species because of how it grows: prostrate, mat-forming perennial spreader; stems root at nodes and extend rapidly by stolons. can grow 30–60 cm outward per season in favorable conditions.. Easiest by stem cuttings (5–8 cm) taken in spring or summer — root in water or moist compost within 1–2 weeks. Can also be divided in spring or autumn. Self-layers freely; detach rooted stolons and pot on.

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 creeping charlie

Take a tip cutting. Snip a 10–15 cm, non-flowering tip from healthy creeping charlie, cutting just below a leaf pair with clean scissors.
Strip the lower third. Pinch off the leaves on the bottom third of the stem and remove any flower buds — energy needs to go into roots, not blooms.
Root it. Stand the bare stem in water on a bright windowsill, or push it into moist seed compost and cover with a clear bag or dome to hold humidity.
Watch for roots. Roots show in 1–3 weeks. For woodier herbs like rosemary, sage and lavender, soil rooting under a dome is more reliable than water.
Pot on. Once roots are 2–3 cm, pot into moderately fertile, moist, well-drained loam and pinch the growing tip to encourage a bushy creeping charlie.

The alternative method

If the main route does not suit your plant or setup, direct-to-soil cuttings under a humidity dome is the next best option for creeping charlie. Skip the water glass and root several cuttings directly in gritty seed compost under a clear dome — this is the more reliable route for woody Mediterranean herbs that sulk in water.

Timeline to roots

Realistically: roots in 1–3 weeks; pot up at 3–4 weeks. These numbers assume spring or summer warmth and bright indirect light. In a cold, dark room — or in winter dormancy — the same creeping charlie 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

Leaving flower buds on the cutting — it spends energy blooming instead of rooting.
Water-rooting woody herbs (rosemary, lavender, sage): they root far better in gritty soil under a dome.
Letting the cutting wilt before it roots — high humidity (a bag or dome) is what carries it through.
Propagating off a stressed, pest-ridden or recently-repotted creeping charlie — always take material from a healthy, established parent.

When to do it

The best window is spring through late 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

For the first two to three weeks after potting, keep the new creeping charlie slightly moister than you would a mature plant and out of direct sun while the young roots adapt from water (or cutting medium) to soil. Hold off all fertiliser until you see a flush of new top growth — feeding a rootless cutting only burns it. Match the parent's needs as the new creeping charlie settles: Thrives in partial shade to full sun. In gardens it performs best in dappled or partial shade where it stays lush; in full sun it spreads more slowly and may scorch in hot, dry summers. As a houseplant or hanging basket specimen, bright indirect light indoors keeps foliage vibrant.

Creeping Charlie propagation — frequently asked questions

What is the best way to propagate creeping charlie?

Softwood tip cuttings in water or soil is the most reliable method for creeping charlie. Propagate creeping charlie from a 4–6 inch softwood tip cutting. Strip the lower leaves, then root the bare stem in water or moist potting mix in bright indirect light. Roots form in 1–3 weeks and the cutting is ready to pot on at 3–4 weeks. Spring and summer are fastest.

Do you need a node to propagate creeping charlie?

For creeping charlie the rooting structure is softwood tip cuttings in water or soil, so a classic "node" matters less than starting with the right plant material — Strip the lower leaves, then root the bare stem in water or moist potting mix in bright indirect light.

How long does it take creeping charlie to root?

Roots in 1–3 weeks; pot up at 3–4 weeks. 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 creeping charlie?

Spring through late 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 creeping charlie in water?

Yes — creeping charlie roots readily in a glass of water as long as a node is submerged. Water propagation is the most beginner-friendly route; just move the cutting to soil before the water roots get long and brittle (around 3–5 cm).
