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.

Why Growers Use Liquid Kelp
| Supports Plant Vigor | Provides seaweed-derived compounds plus phosphorus and potassium to support vigorous growth and overall plant performance. |
|---|---|
| Promotes Stronger Roots | Excellent for root-zone drenches, transplant applications and regular garden feeding where strong root development is important. |
| Potassium Nutrition | Supplies 4% soluble potash (K₂O), an important macronutrient involved in water regulation, plant metabolism and crop development. |
| Phosphorus Nutrition | Provides 4% available phosphate (P₂O₅) to complement broader plant nutrition programs and support active growth. |
| Foliar Compatible | Completely water-soluble liquid formulation mixes easily with water for convenient foliar application. |
| Wide Crop Compatibility | Suitable for vegetables, flowering plants, fruit trees, shrubs, herbs, raised beds, containers, houseplants and ornamental crops. |
Naturally Occurring Seaweed Compounds
| Total Seaweed Sugars | Approximately 50 g/L naturally occurring seaweed sugars. |
|---|---|
| Alginate | Approximately 30 g/L naturally occurring alginate derived from Ascophyllum nodosum. |
| Fucoidan | Approximately 8 g/L naturally occurring fucoidan. |
| Mannitol | Approximately 7 g/L naturally occurring mannitol. |
| Laminarin | Approximately 3 g/L naturally occurring laminarin. |

Mixing: Shake well before use. Add the recommended amount to water and mix thoroughly before application. When combining with other fertilizers or crop inputs, perform a small compatibility test before preparing a large batch.
Foliar Application: Apply during cooler parts of the day and avoid spraying severely heat-stressed, drought-stressed or wilted foliage.
Natural Product Variation: Because this product is derived from naturally harvested seaweed, color, viscosity and naturally occurring nutrient levels may vary slightly between batches.
Storage: Store tightly sealed in a cool, dry location away from direct sunlight. Do not freeze. Keep out of reach of children and pets.
