Meadow Grass Mix

Meadow Grass Mix

Lawn

Wildflower Lawn, Eco Lawn, Prairie Mix, Native Meadow

A naturalistic blend of fine grasses (typically fescues + bents) with native wildflowers — increasingly popular in UK, Northern Europe, and North America as a low-input, pollinator-friendly alternative to traditional lawns. Requires very low fertility soil to thrive (wildflowers are outcompeted by grasses on rich soil). Mow only 2–3 times per year: once in late spring before flowers set seed, once in late summer after seed drop, and optionally a short autumn cut. Do NOT fertilise — excess nutrients cause rank grass growth that smothers wildflowers. First year: mow at 7–10 cm monthly to prevent any one species dominating; flowers establish in year 2 onwards. Soil prep is critical: remove topsoil or use a subsoil seed bed to reduce fertility. Yellow rattle (Rhinanthus minor) is a hemi-parasitic wildflower that suppresses aggressive grasses — include in mix for better floral diversity. Ideal for slopes, orchard understorey, wildlife gardens, and low-traffic areas.

When to sow meadow grass mix

Sow 6–8 weeks before your first autumn frost.

Dashed line: typical first autumn frost in zone 7 (Nov 1). Zone dates are averages; most of the UK is zone 8–9, central Europe 6–7 and the Baltics and Scandinavia 4–6. In the app, Tomatograph uses your garden's own frost dates.

How to establish and care for meadow grass mix

  1. 1

    Lower the fertility

    Wildflowers lose out to grass on rich soil. Strip the topsoil or sow into subsoil, and include yellow rattle to keep vigorous grasses in check.

  2. 2

    Sow in autumn

    Sow in early autumn and rake seed lightly into the surface.

  3. 3

    First-year mowing

    In the first year, mow to 7–10 cm about once a month so no single species takes over. Flowers usually appear from the second year.

  4. 4

    Mow two or three times a year

    Once established, mow in late spring, again in late summer after seed has dropped, and optionally once in autumn. Never feed.
