Wool pellets for seed starting? You heard me right!
I know seed starting can be a little tricky and once you find a mix that works for you, it's hard to pivot and try another method. But one thing wool pellets do better than their water retention soil amendment counterparts (i.e. peat, vermiculite, perlite, etc.) is they provide nutrients for your seedlings as they grow. Wool pellets slowly release nitrogen, potassium, and other micronutrients to aid in seedling health and growth.
If you're looking to incorporate wool pellets into your seed starting mix, below is a recipe from Blossom and Branch Farm for inspiration:
Wool pellets retain moisture well, so if you’re starting seeds in trays, you might want to reduce your watering a little. Cinnamon has been shown to have to have some anti-fungal properties, so I do recommend adding it to the recipe. Our pellets are 100% sheep wool, so they do have the distinct smell of sheep. The smell mostly derives from the natural oil, lanolin, that coats the wool fiber. The cinnamon also helps lessen the smell of the wool, so if you're worried about that, just make sure you add the dash of cinnamon. We sell our wool pellets online and can ship anywhere in the United States, you can purchase here.

Happy seed starting!
