Source untreated seeds from reputable suppliers

Microgreen seeds are genetically identical to regular garden seeds, but they must be untreated and food-safe since you eat them raw within days of sprouting. Garden seeds are often coated with fungicides unsafe for consumption.

What to Look For

• Explicitly labeled untreated and food-safe
• Germination rate of 90%+ (reputable suppliers publish test results)
• Organic certification (USDA Organic, CCOF)
• No fungicide, synthetic polymer, or talc coatings

Trusted Suppliers

• True Leaf Market — specializes in microgreen and sprouting seeds, wide variety, competitive pricing
• Johnny's Selected Seeds — 60+ microgreen varieties, extensive trial data, employee-owned since 1973
• High Mowing Organic Seeds — 100% certified organic, highest germination rates
• Mumm's Sprouting Seeds — Canadian supplier, organic certified

Tips

• Store seeds in airtight containers at 40-50°F with desiccant packs. Most seeds last 3-5 years stored properly
• Test old seeds on a damp paper towel — if fewer than 8 of 10 germinate, viability is declining
