Some tips for generating publicity for your plant sale or other event:
There are many opportunities to get your event publicised for free.
National media and websites
Free listing in Daily Telegraph online:
email your event details including contact phone number and website to
gardening@telegraph.co.uk or write to Gardening Listings, The Daily Telegraph, 111 Buckingham Palace Rd, SW1W 0DT
Great British Life publishes a series of county magazines (
Derbyshire Life, 
Surrey Life etc) with on-line versions. You can submit charity events for listing:
Local media and locally oriented “What’s On” websites
Most local newspapers, magazines, radio stations and on-line listings websites have "What's On" sections to which you can add events in aid of charity for free. If you ring the news desk with a well-prepared précis of your event (Date, time, entry fees, parking, disable facilities, refreshments, items of special interest, entertainment, contact details and so on) and an explanation of what Plant Heritage is all about, you may also be able to persuade a reporter to cover the event or write a ‘teaser’ for it.
Find free listings websites by googling: “what’s on” + your county
Local government and tourism agencies are hungry for events to draw visitors to your area and will have website listings and possibly also free newsletters or magazines. It is also worth asking the tourism offices to display flyers in their Tourist Offices promoting your event.
