About Mignonette Alpine Strawberry
Fragaria vesca 'Mignonette' · also called Mignonette strawberry, miniature strawberry · edible
'Mignonette' is a classic French alpine strawberry forming compact, runnerless clumps that bear tiny, intensely fragrant red berries all season. Tolerant of partial shade and ideal for edging, pots and potager borders, it is easily raised from seed and comes true. The aromatic fruit is best eaten fresh, picked little and often through summer and autumn.
Preferred mix: Rich, humus-laden, moisture-retentive, free-draining soil
Watch for — Drought stalling production: Clumps stop fruiting and flag if the shallow root zone dries, a frequent issue in pots. Keep moisture even and mulch to sustain all-season cropping.
Why mignonette alpine strawberry needs this mix
Mignonette Alpine Strawberry hates drying out, so it wants a mix that stays evenly moist — but it still needs perlite so "moist" never tips into "waterlogged".
- Mignonette Alpine Strawberry comes from damp, shaded forest floors and has fine roots that scorch and brown the moment the rootball dries — the mix has to hold a steady reserve.
- Coir and compost give that reserve, while perlite keeps enough air that the constantly-moist mix does not turn anaerobic.
- Even moisture also keeps its thin leaves from crisping at the edges, which is this plant’s most visible stress signal.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons mignonette alpine strawberry struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A free-draining, gritty mix dries too fast for mignonette alpine strawberry — you get crispy brown edges and frond or leaf drop within days of one missed watering.
- A pure, airless peat mix swings the other way: it holds water but suffocates the fine roots and rots the crown.
- Letting the mix dry to the point it shrinks from the pot is very hard to re-wet evenly and stresses the plant badly.
Using a sharp, fast-draining "houseplant" or cactus-leaning mix that lets mignonette alpine strawberry dry out. It needs a moisture-retentive but still airy blend.
pH — does it matter for mignonette alpine strawberry?
Mignonette Alpine Strawberry prefers a slightly acidic mix (around pH 5.5-6.5); a peat-free compost-and-coir blend sits there naturally, so routine pH testing is unnecessary.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
DIY mix vs a bagged one
A good peat-free houseplant compost works for mignonette alpine strawberry straight from the bag if you mix in some perlite for air. The DIY ratio above gives a more reliable moisture-to-air balance.
Drainage and the pot
Use a pot with a drainage hole but a less-porous material (plastic or glazed) so it does not dry too fast. Bottom-watering keeps the mix evenly moist without sogging the crown.
Peat-free mixes slump and compact as they hold moisture, so refresh mignonette alpine strawberry's mix every 12-18 months to keep air in the rootball even if the pot size is unchanged. When the time comes, our repotting guide for mignonette alpine strawberry covers the timing and technique step by step.
