Seabird Guano 0-10-0
High-Phosphorus Organic Fertilizer for Blooms, Roots & Fruit Set
Seabird Guano 0-10-0 is a naturally potent source of phosphorus, harvested sustainably from ancient coastal deposits. Unlike other guanos, this seabird-derived blend contains virtually no nitrogen-making it ideal for supporting strong root development, abundant flower production, and fruit initiation without stimulating excess leafy growth. A powerful tool for flowering plants, fruiting crops, and perennial roots, especially in the early stages of bloom and transplanting.
Key Characteristics
-
Boosts Blooming and Root Development
With a 0-10-0 NPK ratio, Seabird Guano delivers phosphorus where plants need it most: in the roots and reproductive structures. It's ideal for flowering perennials, young transplants, and crops that need a push into flowering and fruiting stages. -
How to Use in the Garden
-
Transplanting: Mix 1-2 tbsp per planting hole for strong root establishment.
-
Pre-bloom boost: Scratch 1-2 tbsp into soil around flowering plants a few weeks before bloom.
-
Compost tea: Steep 1-2 tbsp per gallon for 24-48 hours and apply as foliar feed or soil drench.
-
Topdress fruiting crops mid-season to stimulate new blossoms and improve yields.
-
-
Perfect for Flowering and Fruiting Plants
Best used with crops like tomatoes, peppers, eggplants, squash, pumpkins, berries, grapes, and orchard trees. Also excellent for flowering herbs and medicinal plants like echinacea, holy basil, and bee balm. -
Improves Soil Fertility Over Time
As a mineral-rich organic input, seabird guano contributes long-term phosphorus availability, especially in soils low in P. It supports microbial communities that mobilize bound phosphorus into plant-accessible forms. -
Pairs Well in Organic Programs
Works synergistically with nitrogen sources like fish hydrolysate, compost, or cover crop residues. Use in foliar feeding, compost teas, or combined with kelp for bloom-boosting soil drenches.
