What is "Below Standard Seed"?
Simply put, it is seed that doesn't meet our state's (Utah) germination standard, a standard that varies slightly from seed to seed. Any seed intended for gardening that has a below-standard germination rate cannot be sold alongside those that meet the state requirements (which often reflect the national requirements for germination).
We send samples of all our seed to the Utah Department of Agriculture, where they perform several tests to assess the quality of the seed. These state-wide and national seed standards are in line with Association of Official Seed Analysts (AOSA), which exist to ensure consumers that they are getting the highest quality seed, as advertised. Since this seed doesn't meet the state standard, we mark it as "Below Standard Seed".
Low germination seeds are non-refundable.

Generally bunching onions do very well when transplanted. The only time it is best to sow directly is when growing for a young harvest. Start winter harvest bunching onion seeds indoors during the fall. Warmer soil temperatures can help encourage strong germination (50-60 F is suitable).

For a fall harvest (recommended), transplant into their final location in the spring.
