Creeping Charlie (Ground Ivy) care

Light

Picture the indirect light an east-facing window gives mid-morning — that's the brightness creeping charlie grows fastest in. 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. You'll know it's right when new leaves come out the same size and colour as the established ones. Smaller, paler new leaves = move closer to the window.

Watering

Aim for every 5–7 days during the growing season; less in winter for creeping charlie, but treat that as a starting point rather than a rule. A south-facing summer windowsill will dry the pot twice as fast as a north-facing winter room. Lift the pot; if it feels noticeably lighter than it did wet, water it. Prefers consistently moist soil but not waterlogged conditions. Allow the top 1–2 cm to dry slightly between waterings. Drought stress causes leaf curl and browning of margins. In containers, check moisture more frequently in warm weather.

Soil and pot

Creeping Charlie grows best in moderately fertile, moist, well-drained loam. Adapts to clay, loam, and sandy soils across a pH of 6.0–7.5. Rich, moisture-retentive loam produces the most vigorous growth. Avoid permanently waterlogged ground, which leads to stem rot. In containers, use a general-purpose potting mix with added perlite for drainage. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Creeping Charlie sits happiest at around 40–70% humidity and 5–25°C (41–77°F). Tolerates average household humidity. Higher humidity encourages lush trailing growth in hanging baskets; very low humidity can cause leaf-tip browning. No misting is needed outdoors, but indoor plants may benefit from occasional misting in heated rooms during winter. If you keep the room above 5–25°C year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed creeping charlie sparingly. Apply a balanced liquid fertiliser at half strength monthly during spring and summer. Over-feeding promotes excessive, weedy spread. No feeding required in autumn or winter. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on creeping charlie in the Growli community. Each is annotated with the most common cause so you know where to start.

• Powdery mildew — White fungal coating appears on leaves in warm, humid conditions with poor air circulation. Improve airflow, avoid overhead watering, and apply a sulphur-based or baking-soda spray at first sign.
• Invasive spread — Stolons root readily at every node, enabling rapid colonization of lawns and borders. Contain with edging strips, grow in pots, or remove regularly by hand-pulling young stems before they root.
• Leaf scorch — Yellowing or bleached margins occur in intense sun or dry soil. Relocate to partial shade and ensure consistent moisture, particularly in summer.

Propagation

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. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Creeping Charlie is mildly toxic to pets. Glechoma hederacea is not individually listed by ASPCA for cats and dogs. It is documented as toxic to horses in large quantities, where volatile oils (including pulegone-related terpenoids) cause neurological and respiratory signs. For dogs and cats, ingestion of small amounts may cause mild gastrointestinal upset (vomiting, drooling, diarrhea). Exercise caution with pets that chew plants; consult a vet if significant ingestion occurs. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.
