Neptune’s Harvest Organic Fertilizers

We like these fertilizers derived from the mineral rich North Atlantic Ocean and carry several of their different dry and liquid fertilizers.

Neptune’s Crab and Lobster Shell:  5-3-0, plus Calcium (23%) and Magnesium (1.33%) In addition to providing your plants with nutrients, crab shell meal will also help with nematode and fungus problems. Crab Shell is high in Chitin (Kite-en), which promotes the growth of Chitin-eating bacteria in the soil. The exoskeletons of fungus and nematode eggs are high in chitin. Crab shell, when added to the soil, helps to create a hostile environment for the fungus and nematodes by feeding the biological life that eats chitin and chitin-based organisms.

Neptune’s Fish & Seaweed Blend: 2-3-1 A blend of fish hydrolysate and seaweed, which are both known to build sugars in plants. Flowers and foliage will be stronger and more colorful. Blooms will be more plentiful, fragrant, and longer-lasting.

Neptune’s Rose & Flowering Formula: 2-6-4 Uniquely formulated for flowering plants to increase their vigor during flowering and to increase the volume and density of buds that produce healthy, vibrant flowers. Made with fresh fish, molasses, yucca extract, seaweed, and humic acids.

Neptune’s Seaweed Supplement: 0-0-1 Contains over 60 naturally occurring major and minor nutrients and amino acids. It has growth-promoting substances which enhance plant development, color, and vigor, and has also been found to increase plant hardiness and resistance to adverse environmental conditions, such as early frost, extreme heat, and lack of moisture. Used as a seed inoculant, seaweed fertilizer increases and accelerates germination, and enhances the rapid development of a healthy root system.

Neptune’s Tomato & Veg Formula: 2-4-2 A complete fertilizer for your tomatoes and vegetables made from fresh fish, seaweed, molasses, yucca extract and humic acids. Formulated for plants with intense growth requirements it increases stalk and stem mass resulting in higher yields.
