Collect the names and addresses of all your customers, and keep a mailing list. This is one of your most effective advertising tools. A direct mailing sent out at the appropriate time, such as a post card indicating your opening date, the high quality of your fruit, and your desire to see the customer at your farm, gets better results than nearly any other media. If you're selling processed goods, send out a letter regarding your product with an order form. Several types of media are available for advertising, aside from direct mailings.
Newspapers are probably the most popular and effective.
Ad space is usually sold by the column inch. Large ads may be quite expensive, but depending on how many people see it, it could be a lucrative investment. Keep the ads short and simple, don't lose the customer's interest. Photos grab a reader's attention and can increase the effectiveness of your ad. Place the ad in the section where your clientele is most likely to see it.
