Mignonette Alpine Strawberry (Alpine Strawberry) care

Light

In the wild mignonette alpine strawberry grows on the bright edge of a forest canopy, not in the canopy and not in the open. Indoors, that translates to within a metre of an unobstructed window, sheer curtain optional. Full sun to partial shade; 4–6 hours of direct sun is ideal. More tolerant of dappled shade than larger-fruited Fragaria × ananassa cultivars, making it suitable under deciduous trees or in north-facing borders in mild climates. The fastest test: a hand held at the leaf casts a soft-edged shadow at noon — sharp shadow means too much sun, no shadow means too little light.

Watering

For mignonette alpine strawberry in the ground or in a bed, aim for every 2–3 days in growing season; weekly in cool or dormant periods. Soak the root zone rather than misting the foliage; deep, less-frequent watering trains roots downward and produces a more drought-resilient plant by mid-season. Maintain consistently moist soil. Avoid waterlogging, which causes crown and root rot. Water at soil level; wet foliage in humid conditions promotes Botrytis. Container plants need more frequent attention during summer heat.

Soil and pot

Mignonette Alpine Strawberry grows best in humus-rich, free-draining loam; ph 5.5–6.5. Incorporate well-rotted compost or aged manure before planting. Avoid compacted or poorly draining soils. For containers, mix peat-free compost with 20–25% perlite or horticultural grit. 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

Mignonette Alpine Strawberry sits happiest at around 40–70% humidity and 5–26°C (41–79°F). Adapts well to most ambient humidity levels. Prioritise good airflow around the plants rather than managing humidity directly — stagnant, moist air is the primary driver of fungal issues on the fruit. If you keep the room above 5–26°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 mignonette alpine strawberry sparingly. Work a balanced fertiliser into the soil at planting. From first flower bud formation, switch to a high-potassium (tomato-type) liquid fertiliser every 10–14 days until late summer to support fruiting. 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 mignonette alpine strawberry in the Growli community. Each is annotated with the most common cause so you know where to start.

• Botrytis grey mould on fruit — Common in cool, humid seasons. Remove infected berries immediately, improve spacing for airflow, and avoid wetting the fruit when watering.
• Vine weevil larvae — Grubs eat roots from late summer onward, causing sudden wilting and plant collapse. Apply pathogenic nematodes (Steinernema kraussei) to moist soil in late August–September for biological control.
• Bird damage to fruit — Birds target the aromatic fruits as they ripen. Drape fine mesh netting over plants once berries begin to colour, or grow in a fruit cage.

Propagation

Sow seed on the surface of moist compost at 18–21°C after 4 weeks cold stratification; germination takes 2–4 weeks. Alternatively divide established crowns in early spring before growth begins. Does not produce runners. 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

Mignonette Alpine Strawberry is pet-safe. Fragaria (strawberry) is listed by ASPCA as non-toxic to dogs, cats, and horses. All parts of the plant, including fruit and foliage, are considered safe for pets. 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.
