Archipelago Bat Guano 0-7-0 (55 lb)

Good for root development, blooms and fruiting

Archipelago Bat Guano 0‑7‑0 (55 lb) is a premium bat guano fertilizer sourced from nutrient-rich guano deposits. This phosphate fertilizer supports long-term soil fertility and enhanced plant growth by gradually releasing essential nutrients that promote root growth, fruit and flower development, and overall optimal growth.

Key Features & Benefits

  • Balanced Nitrogen-Phosphorus Nutrition: A potent 0‑7‑0 blend (sometimes referred to as bat poop) that provides strong calcium, phosphorus, and trace minerals to support healthy development.
  • Slow-Release Phosphorus: Sustained availability fuels plants over time—ideal for long-term soil fertility enhancement.
  • Improves Soil Microbiology: Encourages beneficial microbial activity for better nutrient absorption and helps maintain soil pH balance.
  • Supports Healthy Plant & Root Growth: Boosts early root growth and ongoing plant vigor for fruitful gardens.

Application Guidelines

  • Soil Enrichment (square feet guide): Apply 1–2 lbs per 100 square feet for general fertilization. Mix into soil before planting or use as a top-dressing during the growing season.
  • Compost Tea: Use in foliar feeding preparations to boost nutrient delivery.
  • Recommended Quantity: A full 55 lb sack covers moderate garden areas or focused planting zones effectively.

Why Choose Archipelago Bat Guano?

  • Natural Phosphate Source: Unlike chemical alternatives, this soft rock guano remains stable in soil and delivers phosphorus gradually.
  • Eco-Friendly: Harvested responsibly from bat colonies, it supports both plant and ecosystem health.
  • Efficient and Safe: Effective with minimal application and gentle enough to avoid over-fertilization risks.
  • Versatile Fertilizer: Excellent for soil preparation, container mix-ins, top-dressing, or use in compost or teas.
