Anyone can apply for up to 20 kits but registrations must be in by 14 February. The campaign is supported by the Big Lottery Fund and led by Royal Botanic Gardens, Kew.
The seed kits are designed to be shared with friends, neighbours and colleagues. There are 100,000 free seed kits available, which once sown will help to create over one million square metres of wild flowers by summer 2016.There are different native seed mixes for England, Scotland, and Northern Ireland, and a bilingual kit for Wales, so participants will receive the right mix for their country.
Anyone can register on behalf of their group by filling in Grow Wild's simple form at www.growwilduk.com/seed-kit. Kits will be sent out in late March, just in time for spring sowing.
Each kit contains enough seeds to cover up to 10 square metres, and can be used to transform any space – from balconies to old boots, streets to shared spaces, boxes to buckets. The kits also contain a getting started guide, DIY bee house and site markers.
Last year, Grow Wild's kits found their way to many different organisations and charities, from Girl Guides groups to homeless people and ex-service associations.
One of last year's kit recipients said: "The free seed kits are a fantastic way of helping an area in so many ways; supporting the local wildlife and pollinator insects, improving the look of the area as well as educational benefits."
Another said: "We applied for free wild flower seed kits: we sowed seeds in planters, wall baskets in the alleyway, and in our own gardens. We also painted wild flower murals, with support from volunteer art students."
