Catmint 'Walker's Low' (Catmint) care

Light

Aim for at least 4-6 hours of direct sun on the leaves. Thrives in full sun (6+ hours daily). Will tolerate light afternoon shade in hotter climates, but flowering is reduced and the plant can become floppy in lower light. If your only bright window faces south, that's perfect for catmint 'walker's low' — same window any aroid would fry on.

Watering

Watering catmint 'walker's low': when the top 5 cm of soil is dry, roughly every 10-14 days during the growing season. 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. Highly drought-tolerant once established. Water deeply but infrequently. Avoid waterlogged soil, especially in winter, as wet roots cause crown rot. Established plants in temperate gardens typically need little supplemental irrigation.

Soil and pot

Catmint 'Walker's Low' grows best in well-drained, lean to moderately fertile loam or sandy loam. Tolerates poor, dry soils exceptionally well. Rich, moist soils promote lush foliage but leggy, floppy stems. Ensure excellent drainage; heavy clay should be amended with grit. A neutral to slightly alkaline pH (6.5-7.5) is ideal. 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

Catmint 'Walker's Low' sits happiest at around 30-60% humidity and -20 to 35°C (-4 to 95°F). Fully hardy and undemanding about humidity. Prefers open, airy conditions which help prevent powdery mildew. Avoid overhead watering and ensure good air circulation around the plant. 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 catmint 'walker's low' sparingly. Apply a balanced granular fertiliser lightly in early spring as new growth emerges. Overly rich feeding produces excessive leafy growth at the expense of flowers; one light application per year is sufficient. 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 catmint 'walker's low' in the Growli community. Each is annotated with the most common cause so you know where to start.

• Powdery mildew — Occurs in humid, poorly ventilated conditions or after midsummer. Improve air circulation, avoid wetting foliage, and cut plants back hard after the first flowering flush to promote clean new growth.
• Floppy stems — Rich soil or insufficient light causes lax, sprawling growth. Grow in full sun with lean soil, or use a grow-through support ring. Cutting back by one-third after first bloom also stiffens regrowth.
• Crown rot — Caused by waterlogged or poorly drained soil, especially over winter. Plant on a slight slope or in raised beds with gritty soil to ensure drainage.
• Aphids — Young shoot tips may attract aphids in spring. Knock off with a strong water jet or apply insecticidal soap; plants usually outgrow minor infestations.
• Cat damage — Cats roll in and chew the foliage due to nepetalactone. Protect young plants with wire cloches until established; mature plants recover well from occasional disturbance.

Companion plants

Catmint 'Walker's Low' pairs well with Salvia nemorosa, Achillea millefolium, Stachys byzantina, and Lavandula angustifolia. These are species with similar light and water needs, so you can group them in the same room or on the same shelf and water as a batch.

Propagation

Divide established clumps in early spring or autumn, replanting sections with healthy roots and shoots. Softwood cuttings taken in late spring to early summer root readily in a free-draining cutting compost. 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

Catmint 'Walker's Low' is mildly toxic to pets. Nepeta (catmint) is not individually listed as toxic by the ASPCA, but the genus can cause mild gastrointestinal upset if ingested in quantity by dogs or cats. Cats may also exhibit behavioural responses (rolling, rubbing) due to nepetalactone. The conservative verdict is mildly-toxic pending a confirmed ASPCA non-toxic listing. 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.
