Frequently Asked Questions
Are all organic seeds non-GMO? Yes, USDA organic certification prohibits genetically modified organisms, so certified organic seeds are non-GMO by definition.
Can I save seeds from organic plants and still call them organic? Seeds saved from certified organic plants can be considered organic if they are grown and harvested following organic standards, but the saved seeds themselves are not certified unless tested and certified by an authorized agency.
Do organic seed catalogs guarantee germination? Most reputable organic seed companies test seeds for germination and provide guarantees or replacements if seeds fail to sprout under proper conditions, but policies vary by company.
Is organic seed certification important for home gardeners? While not mandatory, organic certification assures that seeds were produced without synthetic chemicals, which is important for gardeners committed to organic principles and soil health.
How do organic seed companies prevent contamination? Organic seed producers follow strict protocols including isolation distances, crop rotation, and careful seed cleaning to prevent contamination with non-organic or GMO seeds.
