Can anyone tell me of a resource to send for that has template letter samples for sponsorship,donors etc?
I thought I saw something on ACGA but when I went back to look I could not find.
Why not just write a short paragraph describing your garden, include that as your introductory paragraph in every letter asking for support, and then speak from your heart to ask for whatever you need? You could easily tailor the second paragraph of each letter to fit whatever you hope that person/company can give you. Then your final paragraph could also always be the same, a genuine thank-you for whatever help they can offer.
I think you'll have better luck if they can tell you are sincere than if your letter sounds like a professional letter-writer wrote it.
