You might already be drowning in seed catalogs, but you might be new to gardening or farming and need to find seed suppliers. And even if you have some favorites, it's always nice to check out some new offerings. Here you'll find links to and information about some of the top recommended seed suppliers for small farming and homesteading. They're listed in alphabetical order.
Baker Creek specializes in heirloom seeds, and have some varieties that are hard to find elsewhere. They carry "one of the largest selections of seeds from the 19th century, including many Asian and European varieties." They have over 100 varieties of melon alone! Their website, print catalog and magazine are also a wealth of information.
One of my favorites - especially because they are local to me, but also because their seeds are excellent. One of the best sources for certified organic seeds, they also offer many heirloom varieties. And they sell in large quantities for the small-scale farmer or large homestead gardener. Important to note is that they sell cover crops and pelleted seed.
Fedco specializes in hardy plants for the Northeast climate, and they have five different subcatalogs you can order from via mail and internet only: seeds, organic growers supply, trees, bulbs, and moose tubers (potatoes). Fedco is organized in a cooperative structure, so they are not a for-profit company. They're great for the larger-scale small farmers, but check dates, because they only ship perishable items during certain windows in the spring or fall. They make it easy to facilitate a group order and you will save money doing so.
Founded in 1975, Seed Savers Exchange is a nonprofit, member-supported organization "that saves and shares the heirloom seeds of our garden heritage, forming a living legacy that can be passed down through generations."
