Know where your seed comes from! This unique Fedco feature provides information about the source(s) of each seed variety. Varieties with more than one supplier may have two or more codes. We code according to our best information at press time. When seed is short we must sometimes change suppliers later in the season. With notable exceptions, we generally choose varieties based on their merits rather than on our supplier preferences. We do not offer genetically engineered varieties, although we purchase from corporations engaged in genetic engineering. Use the supplier codes to help you make your own choices about whom you are supporting and which varieties are best for your garden or farm. Codes are as follows:
Small seed farmers including Fedco staff.
Heldover Seed - Like most other seed merchants, we carry over stock from one year to the next, in any given season between 10–30% of offerings. We test all such lots for viability and discard any in doubt. We think you should know as much as possible about our seed. Heldover seed is not necessarily inferior to fresh seed; we have confidence in all lots we offer. We commission two-year productions of some varieties to decrease our growers’ costs, increase their efficiencies and improve their isolations. For germination test results, see here.
Optimal Germination Guide - Sowing seeds at sub-optimal temperatures is the most common cause of failure. We include information in some headers about ideal germination temperatures, taken and extrapolated from tables in Knott’s Handbook for Vegetable Growers ISBN 0-471-73828X and The New Seed-Starters Handbook by Nancy Bubel, ISBN 0-87857-752-1.
