UNBEATABLE QUALITY Experience the power of nature with our Kelp & Seaweed Fertilizer. OMRI listed for organic gardening, GS Plant Foods Liquid Seaweed Fertiliser offers a pure and natural solution for your garden's needs. Enhancing soil conditions, it promotes robust root growth and greater nutrient absorption for thriving plants. Embrace worry-free gardening as our seaweed plant food is free from harmful chemicals, nurturing your plants and preserving the environment with every application.
ORGANIC NUTRIENT BOOST Made from the finest seaweed plant Ascophyllum Nodosum, this is one of nature s miracle plant foods. Our seaweed extract improves your plant s tolerance to excessive heat, wind, drought conditions and more. It increases and stabilizes chlorophyll in plants, which results in darker green leaves and increased sugar content in plants. Investing on our seaweed feed is the best solution for revitalizing your garden, lawn and more.
EASY APPLICATION Apply liquid seaweed & kelp to improve growing conditions in all growth stages. Simply mix 2 ounces (59ml) of this liquid fertiliser concentrate into a gallon of water (3.78l) and apply. Each gallon of this mixture will then cover as much as 1,000 sq ft. Any sprayer will work, but for large areas, the hose end sprayer is easiest! This liquid seaweed feed for plants should be sprayed in the morning or late afternoon when temperatures are lower, and the leaves stoma are open.
