Generous gardeners have helped the National Gardens Scheme raise a record amount for good causes.

Gardeners who open their plots for charity under the NGS’s Yellow Book scheme raised so much cash that the NGS was able to distribute £2,637,000 to charities.

The NGS has given over £15million to Macmillan Cancer Support to date.

Last year, cash raised from charity garden openings across the UK increased by £137,000, a year-on-year rise of 5.48 per cent.

NGS chairman Martin McMillan said the donations were “testament to the extraordinary hard work and generosity of garden-owners” – and said that good weather throughout the summer of 2014 had helped.

Martin said: “I am proud that the NGS is the largest single funder of all our nursing and caring beneficiary charities.”

Beneficiaries of 2014’s distribution included Macmillan Cancer Support (£500,000), Marie Curie Cancer Care (£500,000) and the Carers Trust (£400,000).

Other causes to benefit included Parkinson’s UK (£172,000), Perennial (£150,000), The Royal Horticultural Society (£75,000) and The Garden Museum (£10,000).

Joe Swift, the television gardener, is president of the NGS.
