Know before you buy
Unlike synthetic fertilizers that focus primarily on macronutrients, this seaweed extract provides over 60 essential nutrients, amino acids, and natural growth hormones. It acts more as a plant supplement to improve overall health, root development, and stress tolerance rather than just a quick growth booster.
This formula is highly versatile and safe for a wide range of plants, including vegetables, fruits, trees, shrubs, and turfgrass. Because it is a natural, gentle concentrate, it is suitable for almost any garden application.
Cold-water processing is critical because it prevents heat from destroying delicate growth hormones like gibberellins and cytokinins. By preserving these natural stimulants, the extract remains biologically active and effective at supporting seed germination and plant development.
Both methods are effective depending on your goal. Foliar spraying allows for rapid absorption through the leaves to correct nutrient deficiencies, while a soil drench is best for long-term root health and helping plants recover from transplant shock.
Because it has a very low NPK ratio of 0.1-0.1-1.5, it is significantly less likely to cause fertilizer burn compared to high-concentration synthetic products. However, you should always follow the dilution instructions on the label to ensure optimal results.
Yes, this is an all-season product. You can use it during the initial planting phase to support germination and root growth, and continue applying it periodically throughout the season to maintain vibrant foliage and overall plant vigor.
