Garden Magazines - give a garden magazine subscription
Give them a magazine subscription to a garden magazine
Another gift idea - which lasts longer than a day - would be a magazine subscription. There is something lovely about coming home to find a gardening magazine waiting for you, usually awash with colour photographs and inspirational ideas.
Great Magazines have gardening magazines Garden News (with topical, up-to-date gardening news, practical information, tips and ideas) and Garden Answers, (the latter describing itself as the inspirational monthly gardening magazine for amateur gardeners who want a beautiful garden).
