Welcome to Maxsea. We are a small, family-owned company with one simple goal: to make the very best garden products on the market using the natural resources around us.
My name is John Dimmick, and I have loved horticulture my whole life. As a young child, I was introduced to organic farming by a rather eccentric local gardener and I’ve been captivated ever since. I founded the company that would come to include Maxsea in 1967 as a venture that would repurpose wasted sawdust and bark from my family’s sawmill operations. My first product was an orchid-growing medium utilizing chipped redwood bark.
Pleased with the success of the orchid product, I created a line of organic potting soils and custom growing media. Then, in the mid 1980’s, I set my sights on fertilizer. I had long been fascinated by the benefits of seaweed and so began working with soluble seaweed granules, blending them with organics and food grade ingredients to create a superior product to nurture gardens and help them thrive. Our first Maxsea Plant Food formula was offered for sale in 1989.
Every aspect of our business is small and handcrafted, and so we conduct sales accordingly. Maxsea sells to high-quality independent nurseries, garden centers and garden professionals. We do not sell to discount chains or big box retailers. Our Maxsea dealers are among the top nurseries and garden centers in the United States.
Owners: John and Michelle Dimmick
John and Michelle are avid and passionate gardeners who divide their time between homes in Southern Humboldt County, where the manufacturing facility is located, and Marin County, just outside San Francisco.
Michelle is a graduate of the California School of Culinary Arts and as such, she makes fantastic use of the bounty from the vegetable garden. John, in addition to manufacturing garden products, owned and operated a retail nursery and garden supply for 20 years.
