Care at a glance

Light

Mara des Bois Strawberry needs sun on the leaves, not just bright ambient room light. Full sun, at least 6-8 hours daily, drives the best yields and sweetest fruit. In hot regions light afternoon shade reduces sun-scald on berries but too much shade gives soft, bland fruit and encourages mildew. A south or west-facing windowsill in the northern hemisphere is the default; anywhere else, expect the plant to stretch and pale out within a season.

Watering

Outdoor mara des bois strawberry crops want when the top 2-3 cm of soil is dry, roughly every 2-4 days in summer. The single best habit is a finger-test before watering — push a finger 3-4 cm into the soil. Damp = wait a day; dust-dry = water deeply at the base of the plant. Keep the root zone evenly moist, especially during flowering and fruiting; never waterlogged. Water at soil level in the morning to keep foliage dry. Containers dry fast and may need daily watering in heat. Drip or a soaker hose reduces fruit rot.

Soil and pot

Mara des Bois Strawberry grows best in rich, fertile, free-draining loam, slightly acidic to neutral (ph 5.5-6.8). Work in plenty of well-rotted compost or manure before planting. Avoid heavy, waterlogged ground that rots crowns. Raised beds or a peat-free, loam-based compost in containers give the best drainage and warmth. 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

Mara des Bois Strawberry sits happiest at around 40-70% humidity and 15-26°C (59-79°F). Tolerates a wide ambient range outdoors. Good airflow around plants is more important than humidity level; crowded, humid, still conditions invite grey mould (botrytis) and powdery mildew on leaves and fruit. If you keep the room above 15 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 mara des bois strawberry sparingly. Apply a balanced general fertiliser at the start of growth in spring, then switch to a high-potassium (tomato-type) feed every 10-14 days once flowering begins to sustain repeat cropping. Top-dress containers with fresh compost each spring. Avoid excess nitrogen, which gives leaf at the expense of fruit. 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 mara des bois strawberry in the Growli community. Each is annotated with the most common cause so you know where to start.

  • Grey mould (botrytis)Fuzzy grey rot on ripening berries in damp, crowded conditions. Improve airflow, mulch with straw to lift fruit off soil, water at the base, and remove infected berries promptly.
  • Slugs and snailsChew holes in ripening fruit overnight. Mulch with straw, use beer traps or wildlife-safe ferric-phosphate pellets, and harvest ripe berries quickly.
  • Powdery mildewWhite powdery coating on leaves that curl upward at the edges. Space plants for airflow, avoid overhead watering, and remove old leaves after fruiting.
  • Birds stripping fruitBirds take ripe berries fast. Net plants once fruit begins to colour, keeping netting taut so birds cannot become entangled.

Propagation

Easiest from runners: peg the plantlets into pots or soil while still attached to the parent, let them root over a few weeks, then sever and transplant. Replace the bed every 3-4 years as vigour and yield decline. 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

Mara des Bois Strawberry is pet-safe. ASPCA-listed as non-toxic to cats, dogs, and horses (Strawberry, Fragaria spp.). Leaves, fruit, and runners are safe, though large amounts of fibrous foliage can cause mild, self-limiting stomach upset; keep slug pellets and pesticides away from 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.

Mara des Bois Strawberry care — frequently asked questions

What is the common name for Fragaria × ananassa 'Mara des Bois'?

Fragaria × ananassa 'Mara des Bois' is most commonly called Mara des Bois Strawberry, but it is also known as Mara des Bois strawberry, ever-bearing strawberry. The names refer to the same species, so care instructions for Mara des Bois Strawberry apply identically to anything sold as ever-bearing strawberry.

How much light does mara des bois strawberry need?

Mara des Bois Strawberry grows best in direct sun (at least 4-6 hours). Full sun, at least 6-8 hours daily, drives the best yields and sweetest fruit. In hot regions light afternoon shade reduces sun-scald on berries but too much shade gives soft, bland fruit and encourages mildew.

How often should I water mara des bois strawberry?

Water mara des bois strawberry when the top 2-3 cm of soil is dry, roughly every 2-4 days in summer. Keep the root zone evenly moist, especially during flowering and fruiting; never waterlogged. Water at soil level in the morning to keep foliage dry. Containers dry fast and may need daily watering in heat. Drip or a soaker hose reduces fruit rot. The finger-test (or lifting the pot to feel its weight) beats a fixed weekly calendar because pot size, light, and season all change how fast the soil dries.

Is mara des bois strawberry toxic to cats and dogs?

Mara des Bois Strawberry is pet-safe. ASPCA-listed as non-toxic to cats, dogs, and horses (Strawberry, Fragaria spp.). Leaves, fruit, and runners are safe, though large amounts of fibrous foliage can cause mild, self-limiting stomach upset; keep slug pellets and pesticides away from pets.

What USDA hardiness zone does mara des bois strawberry grow in?

Mara des Bois Strawberry is rated for USDA zone 4-9 (winter-hardy outdoors; mulch crowns in cold zones) and RHS hardiness H6. Outside that range, grow it as a container plant that overwinters indoors before the first hard frost.
