Farmers and gardeners use seed catalogs to germinate ideas for their upcoming planting seasons. The catalogs provide information in an efficient, easy-to-reference format. There are many ways to obtain seed catalogs free of charge from online or physical locations, and you can use them to find information about seeds that you may not have been aware of previously.
Order catalogs through the websites of nurseries or suppliers that you are familiar with. Most of these sites offer online order forms that you simply complete and submit. The site should tell you how long you will have to wait to receive your catalog.
Drop by your local nursery and ask them if they have any catalogs for the products they carry. They should offer seed catalogs that you can take.
Call the seed company directly and ask them to send you a catalog. Most of them will do so happily without charging you for it.
