Frequently Asked Questions

What is an SFI cover crop mix?

It’s a multi-species blend containing at least 2 species from two plant families (grasses, legumes, brassicas, herbs) that meets SFI standards.

When should I sow it?

Sow in spring for CSAM2 or summer for SOH3, when soil temperature exceeds 7°C.

How long does it need to grow?

It must be well-established throughout winter, providing full ground cover to prevent soil exposure.

Can I graze it?

Yes – light grazing is permitted if the cover remains rooted and soil isn’t damaged.

What environmental benefits does it offer?

Reduces erosion, builds soil structure and organic matter, supports biodiversity, and helps reduce runoff.

Can it be used as a green manure?

Yes – these mixes are designed to be cover crops or green manure before cash-cropping, supporting both soil health and SFI compliance.

Frequently Asked Questions

Are these mixes compliant with SFI or DEFRA schemes?

Yes, our SFI wildflower mixes are created to meet current DEFRA and stewardship scheme specifications – ideal for use in SFI and other agri-environmental programmes.

Where can I sow these mixes?

Common areas include buffer strips, field margins, headlands, pollinator habitats, and low-input grassland.

What species are included?

Mixes include native UK wildflowers such as birdsfoot trefoil, knapweed, yarrow, and clovers – selected for ecological value and scheme compliance.

How much seed do I need per hectare?

Sowing rates vary, but typical guidance is 10–15kg/ha for grass and wildflower mixes or 5kg/ha for flower-only blends.

When is the best time to sow?

Sow in spring or autumn for best establishment – conditions should be moist, and the ground should be weed-free and well-prepared.

Do these mixes need maintenance?

Yes, most SFI mixes benefit from cutting once or twice a year to encourage flowering and reduce grass dominance.
