Moroccan Mint (Spearmint 'Moroccan') care

Light

Picture the indirect light an east-facing window gives mid-morning — that's the brightness moroccan mint grows fastest in. Performs best in full sun to partial shade — 4–6 hours of light daily. Tolerates more shade than many herbs but flavour and essential oil content are stronger in bright light. Avoid deep shade, which causes leggy, pale growth. 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 3–5 days in summer; every 7–10 days in winter for moroccan mint, 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 (not waterlogged) soil. Unlike most herbs, Moroccan Mint tolerates moderate moisture but will wilt quickly if allowed to dry out. Water thoroughly and allow excess to drain. Mulch outdoor plants to retain moisture.

Soil and pot

Moroccan Mint grows best in rich, moist, well-drained loam. Thrives in fertile, moisture-retentive but not waterlogged soil. A standard multi-purpose potting compost with added perlite (20%) is suitable in containers. pH 6.0–7.0. Benefits from regular addition of organic matter outdoors. 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

Moroccan Mint sits happiest at around 40–70% humidity and 5–30°C (41–86°F). Appreciates moderate to high humidity. Tolerates average household humidity but may show leaf tip browning in very dry indoor air. Mist lightly or place on a pebble tray with water. Good airflow prevents powdery mildew. If you keep the room above 5–30°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 moroccan mint sparingly. Apply a balanced liquid fertiliser (e.g., 10-10-10) every 4 weeks during the growing season. Container-grown plants benefit from monthly feeding as frequent watering leaches nutrients. Avoid high-phosphorus formulas; nitrogen supports leafy growth. 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 moroccan mint in the Growli community. Each is annotated with the most common cause so you know where to start.

• Powdery mildew — White powdery coating on leaves, especially in warm, humid, poorly ventilated conditions. Improve airflow, avoid wetting foliage, and thin dense growth. Treat with a bicarbonate spray or dilute neem oil if persistent.
• Invasive spreading — Underground stolons spread aggressively and can colonise a large area within one season. Grow in a sunken container or in a pot to contain spreading. Check borders annually and remove runners.
• Mint rust (Puccinia menthae) — Orange-brown pustules on leaves and stems in late summer. Remove and bin all infected material (do not compost). Destroy and replace severely infected plants; rotate planting positions to break the cycle.

Propagation

Extremely easy — divide clumps in spring or autumn, separating rooted runners and replanting immediately. Take 10 cm stem cuttings and root in water or moist compost within 1–2 weeks. Does not breed true from seed; vegetative propagation maintains the cultivar. 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

Moroccan Mint is pet-safe. Mentha spicata (spearmint) is listed by ASPCA as non-toxic to dogs and cats. Moroccan Mint as a spearmint cultivar shares this profile. Note: peppermint and pennyroyal are different species with higher menthol/pulegone content and different toxicity considerations — this spearmint cultivar is safe. 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.
