A well-known programme in the UK, National Garden Gift Vouchers is praised for its long-standing support of gardening and associated charitable endeavours. The non-profit Horticultural Trades Association (HTA) runs a programme that provides coupons redeemable at more than 1,400 garden centres and nurseries throughout the UK for a variety of goods. These gift certificates are given about a million times a year and are very well-liked by gardeners. Every voucher contributed or used goes towards promoting gardening and causes related to gardening because the HTA reinvests the earnings from the initiative.

The National Garden Gift Vouchers programme supports several other initiatives and causes. The National Children's Gardening Week is one such campaign, during which time project ideas are shared to get kids excited about gardening. These activities are made to be entertaining and instructive, encouraging kids' imagination, well-being, and global awareness. The programme has given thousands of pounds worth of gift certificates to schools for gardening projects as part of this campaign. The charity Greenfingers, which builds lovely gardens in hospices for kids to enjoy with their families and offers areas for play, relaxation, and rehabilitation, is another cause they are delighted to support.
