Boca Hydro Pure Organic Liquid Kelp Fertilizer 0-4-4

Premium Ascophyllum nodosum Seaweed Extract for Gardens, Fruit Trees, Containers, Raised Beds & Foliar Feeding

Boca Hydro Pure Organic Liquid Kelp Fertilizer 0-4-4 is a concentrated liquid seaweed extract derived from Ascophyllum nodosum, a nutrient-rich North Atlantic brown seaweed widely used in professional agriculture, horticulture and plant nutrition programs.

Unlike heavily diluted seaweed products, this concentrated extract contains approximately 22–24% total solids and supplies naturally occurring seaweed compounds including seaweed sugars, alginate, fucoidan, mannitol and laminarin.

The naturally occurring 0-4-4 fertilizer analysis provides phosphorus and potassium while the seaweed extract supports root development, plant vigor, nutrient utilization and overall plant resilience. The formula is completely water soluble and may be used as a soil drench, root-zone treatment or foliar spray.

Boca Hydro Pure Liquid Kelp is ideal for vegetables, fruit trees, citrus, mango, avocado, flowering plants, herbs, container plants, raised beds, houseplants, transplants, ornamentals and general garden use.
