We currently operate two separate 100% organic farms in West Grove and Oxford PA. Our mushroom packing and shipping facility is located in Landenberg, PA. Mother Earth Organic Mushrooms offers fresh, dried, and quick frozen mushroom varieties. With a strong focus on food safety and quality, the farm is proudly devoted to providing healthy high quality organic mushrooms.
