Hedge Woundwort (Whitespot) care

Light

The Goldilocks zone. Not the south-facing windowsill (too hot, too direct), not the back of the room (too dim, growth stalls). Performs best in partial to full shade; tolerates some morning sun but scorches in prolonged direct afternoon sun. If you can't decide, a free phone lux-meter app aimed at the leaf at noon should read between 800 and 1,500 lux.

Watering

Watering hedge woundwort: regularly during active growth; reduce in winter. The number that matters isn't the day of the week — it's how dry the top 2-3 cm of the pot feels. A finger in the soil tells you more than a watering app. After every watering, tip the saucer. Prefers consistently moist soil; drought stress causes leaf scorch and premature flowering; does not tolerate waterlogging.

Soil and pot

Hedge Woundwort grows best in moist, humus-rich loam or clay; tolerates a range of ph. Grows in acidic, neutral, or mildly alkaline soils; benefits from added organic matter in thin or sandy ground. 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

Hedge Woundwort sits happiest at around Moderate to high (ambient outdoor) humidity and -20 to 25°C (-4 to 77°F). As a woodland native it appreciates the naturally higher humidity under a tree canopy; no supplemental humidity needed in most UK gardens. If you keep the room above 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 hedge woundwort sparingly. Feed with a balanced general fertiliser in spring only if growth is poor; on fertile woodland soils no feeding is required. 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 hedge woundwort in the Growli community. Each is annotated with the most common cause so you know where to start.

• Powdery mildew — Common in dry conditions or crowded plantings; improve air circulation and avoid wetting foliage; affected leaves can be removed.
• Invasive spread — Rhizomes and prolific self-seeding can make it invasive in borders; remove seed heads before they ripen and divide every 2–3 years to keep in check.
• Slugs and snails — Young spring shoots are targeted by slugs; use copper barriers or biological nematode controls in susceptible gardens.

Propagation

Divide established clumps in spring or autumn; alternatively sow seed in a cold frame in autumn or early spring — seed germinates readily at cool temperatures (10–15°C). 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

Hedge Woundwort is mildly toxic to pets. Not listed on the ASPCA toxic plant database, but the plant is a member of Lamiaceae and produces strongly fetid volatile compounds in its foliage. No confirmed severe toxicity reports in pets exist; classified mildly-toxic as a precautionary measure since ingestion may cause mild gastrointestinal upset. 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.
