Establish and maintain a herbal ley with a seed mix containing at least one grass, two legume, and two herb or wildflower species. You must minimise nitrogen fertiliser use and must not use pesticides, except for specific weed control or to re-establish the ley.

schedule When to do

The herbal ley must be established by early autumn within the first 12 months of the action's start date. It needs to be maintained until the end of the second summer after sowing, then re-established and maintained until the action's end date.

  • field operations at a land parcel level and associated invoices, including details of the seed mix used

tips_and_updates Additional Advice

Guidance is provided on selecting a high-quality seed mix beyond the minimum requirements, adhering to buffer strip rules near hedgerows, and managing the ley through grazing or cutting. A rest period of about 5 weeks between early May and late July is suggested to benefit pollinators.
