About Us

MaineStream Organics is a division of Ocean Organics in Waldoboro, Maine. We manufacture organic-based fertilizers for home gardeners, and professional groundskeepers and turf managers. Our sister company, Emerald Isle Ltd., has provided state of the art products to golf courses and athletic fields for 30 years.

These products are safe and effective, tested and proven through university research and independent studies, and most important, confirmed through continuous use with superior results on golf courses, playing fields and gardens nationally and internationally.

MaineStream Organics manufactures superior, earth-friendly, easy-to use organic-based fertilizers containing seaweed, crab meal, fish meal, alfalfa, feather meal and other natural high quality ingredients. Our products stimulate soils, increase flower and vegetable blooms and produce beautiful, healthy lawns and gardens.  Our specially-formulated seaweed extract-based liquid fertilizers help plants thrive through summer stresses.

We developed MaineStream Organics’ “Organics The Easy Way” line of fertilizers using two primary principles:

1. The products had to be highly effective, and like our professional line, had to meet or exceed the growth obtained from synthetic fertilizers.
2. The products had to be safe enough for use on our own families’ lawns and gardens—and we have little ones!

We are happy to say that we have exceeded our goals.  Try our products, and see for yourself!
