We’re Ethan and Carly Zierke. We started Sweet Season Farm in 2022 to make local food more accessible for our neighbors in Northeast Iowa.

We grow produce that tastes great, holds up in the fridge, and earns its place as a staple in your kitchen.

Around here, we believe good local food should fit into everyday home cooking, whether that’s a tossed-together Tuesday night stir fry or pulling off the perfect ratatouille when inspiration strikes.

A big part of our work happens beyond the field. We help connect what’s growing nearby to what ends up on your plate through flexible recipes, storage tips, and simple substitutions. The goal isn’t perfection. It’s finding a rhythm that keeps meals interesting, reduces food waste, and makes local food feel doable week after week.

Our practices

Our farm is certified organic and certified by the Real Organic Project. We put a lot of care into growing high-quality, nutrient-dense produce while stewarding the environment.

Where to find our produce

  • Decorah Farmers Market, Saturdays 9 a.m. to Noon (May–October)

  • Our online store, with Wednesday home delivery in Decorah (May–November)

Local food works best when it fits into real life.
