Description

Slope & Erosion-Control Mix is designed to stay put. Creeping red fescue spreads by rhizomes to bind the surface, deep fine-fescue roots anchor the bank, and white clover closes the canopy and feeds the stand — a low-mow planting that stabilises slopes and swales and rarely needs cutting on a grade.

Seed specifications

Species Common name Leaf / blade Zone Height Bloom ASPCA
Festuca rubra ssp. rubra Creeping red fescue Fine blade 3–8 5–8 in unmowed Insignificant Non-toxic
Festuca spp. (fine) Fine fescue Fine blade 3–8 5–9 in unmowed Insignificant Non-toxic
Trifolium repens White clover 8–15 mm leaf 3–10 4–8 in (2–4 mowed) White, May–Sep Non-toxic

Why choose Slope & Erosion-Control Mix

On a slope, roots are everything. Creeping red fescue spreads by underground rhizomes to lock the soil surface into a continuous mat, while the combined fibrous roots of the fine fescues reach deep to hold a bank against rain and run-off. USDA NRCS lists fine fescues among the grasses used for vegetative erosion control for exactly this reason.

White clover fills the gaps between grass crowns with a living ground cover, closing the canopy quickly so bare soil is not left exposed to wash away, and fixing its own nitrogen so the planting establishes without a heavy feeding programme that would otherwise wash off a slope.

Because fine fescues are slow and low-growing, the finished planting needs little or no mowing — a real advantage on a grade that is awkward or unsafe to mow. Leave it long for the deepest roots and the best soil-holding.

Best uses

Application Suitability Notes
Slopes and embankments Excellent Deep, spreading roots stabilise soil and resist erosion.
Swales and drainage edges Very Good Tolerates variable moisture once established.
Low-mow and no-mow areas Excellent Fine fescues stay low; mow rarely or not at all.
Shady banks Very Good Fine fescues are among the more shade-tolerant grasses.
Overseeding thin slopes Very Good Broadcast to thicken a failing bank.
High-traffic play lawns Moderate Built to hold soil, not for hard sports wear.

Zone & climate compatibility

Zone Performance Notes
Zone 3–5 Excellent Cold-hardy; sow Apr–May once soil hits ~50°F. Stays fine and tight in cool seasons.
Zone 5b–7 Excellent Best overall performance. Autumn sowing (Aug–Sep) gives the strongest first-season stand.
Zone 8–9 Very Good May idle in peak summer heat and recover in autumn; a light autumn overseed keeps density.

How to sow Slope & Erosion-Control Mix

  1. Prepare a firm, weed-free seedbed. Rake to a fine, level surface. For overseeding, mow the existing lawn to 1.5–2 in and scratch up thin or bare areas so seed reaches the soil.
  2. Broadcast at the right rate. Sow at about 1– per 1,000 sq ft for a new lawn, or ½– per 1,000 sq ft to overseed. Cross-sow half the seed in a second direction for even cover.
  3. Keep seed shallow. Rake lightly for soil contact and roll or tamp; do not bury fine clover and fescue seed — it needs light contact with the surface.
  4. Water lightly and often. Keep the surface consistently moist with one or two light waterings a day until seedlings appear — typically 7–14 days for fescue and clover.
  5. Hold the first mow. Let seedlings reach 3–4 in and root in before the first cut, then mow high (2.5–3 in) through the first season.
  6. Sow in the right window. Early autumn is ideal in most regions; spring works where summers are mild. Aim for soil temperatures of about 50–65°F.

Care & maintenance

  • Mow high and rarely. Keep the blade at 2.5–3.5 in; taller growth shades soil, holds moisture, and crowds out weeds.
  • Skip the nitrogen. The clover fixes its own; over-feeding with synthetic nitrogen favours grass and weeds over clover.
  • Water deeply, not often, once established to encourage deep roots.
  • Top-up overseed each autumn in high-traffic or hot-summer areas to keep the stand dense.
