On this episode of Garden Talk, UAF Cooperative Extension Agent and Associate Professor Darren Snyder discusses the benefits of using seaweed to create a fertile, living garden soil. Snyder shares that seaweed provides essential micronutrients and macronutrients like potassium, which are crucial for plant growth. He offers practical advice on ethically gathering seaweed from shorelines, emphasizing the importance of collecting only detached seaweed. The episode also covers methods for processing and applying seaweed, such as “seaweed tea” or directly incorporating it into the soil as a fall amendment or a protective mulch to enrich the soil and suppress weeds.
