What we do

For too long, organic fertilizer companies have been adding ingredient after ingredient into their fertilizers—creating blends upon blends of fertilizers with the same 10, 15, or even 20 ingredients. All the while, these companies include unnecessary fillers and source their ingredients with little mind for sustainability or environmental health.

High Island is different. From our single-ingredient All Purpose Organic Fertilizer to our post-consumer wood-based BioCarbon Minerals, we create products that use as few ingredients as possible, sourced as sustainably as possible, and are kept as natural as possible.

With High Island products, you’ll finally be able to experience products that are truly natural.

What they’re saying

Thanks #HighIsland for the quick delivery! I needed a project to do, that didn't involve baking, while I finish out my quarantine.

Love it! Thank you! Looking forward to starting my [Vegetable Garden Gardening Pack] when we warm up a bit here in Michigan.

High Island’s All Purpose Organic Fertilizer provided significant increases in size of our gourmet garlic and potatoes, far beyond our expectations. We would highly recommend High Island products for other growers.

I’m a longtime and very particular organic gardner. I never change products. Ever. Your fertilizer is great! I’m so happy. I’m making the switch!

Thank you so very much for the [fertilizer] and delivery--fabulous customer service. We can't wait to get it on the fields

I used [the fertilizer] on a variety of plants in the vegetable garden—raspberries, asparagus, annuals, perennials, and shrubs. There was a noticeable improvement over previous years’ performance. I also used it on a number of seed started perennials. When they were moved up from plug trays to 4” pots, they did not look very healthy. In less than two weeks after fertilizing them, the leaf color had improved and they grew vigorously. I plan on using it as a dormant fertilizer this November on shrubs and perennials to get a jump start on next springs work.”
