Why Use Seaweed Fertilizer?
Seaweed fertilizer is more than just plant food. It contains natural hormones that encourage root growth. It also has trace minerals that plants need to thrive.

Key Features to Look For
When you shop for seaweed fertilizer, keep a few things in mind.
- Form: Seaweed fertilizer comes in different forms. Liquid concentrates are easy to mix and use. Granular forms are good for slow release. Powdered versions can be mixed with water or applied directly.
