Nothing is better for blooming flowers or ripening fruits than pure, high-phosphorus Sunleaves Jamaican Bat Guano (1 - 10 - .02). Jamaican Bat Guano is most effectively used at the root zone to heighten root and flower development. Gardeners can amend their soil with it, use it as a top dressing or create a "guano tea" and apply it directly to plant roots in a fortified water dilution. Eco-friendly harvesting from centuries-old cave deposits.
