Seed sourcing does not need to produce the anxiety it seems to. My advice is to use reputable suppliers who cater to commercial scale growers, and don't overthink it. That goes for this question, which I get all the time.
How do you feel about organic seeds? I want to use them but do you bother?
We use organic seed as much as we can. But we will not pay excessively premium prices for them. Suppliers recommended by SPIN farmers can be found here. If you have not made a seed order yet, then you might have to source locally. If you want onion sets/garlic then you need to act quickly. We just bought 500 lbs. of sets, and cleaned them out of their first shipment. I would suggest an ambitious onion/garlic planting in your first year. Say, 50 lbs. of each.
If a supplier is out of the seed you want, see if you can pre-order and pay over the phone and get 50 lbs. of each reserved from their next shipment. A good relationship with seed suppliers is a good asset to have, so make an extra effort to establish them early in your career.
This is SPIN farmer Frank Frazier's main 2015 seed order for Mooseview Farm in Brookfield NH . He'll be testing out 8 new varieties of lettuce for a new salad mix this year. He likes High Mowing Seeds.
