Know before you buy
The 7-3-1 ratio indicates a high nitrogen content, which is primarily responsible for lush, green foliage and vigorous vegetative growth. While it provides some phosphorus and potassium for root and overall health, it is best used when you want to encourage leafy development in vegetables, flowers, or shrubs.
Yes, this product is suitable for houseplants, but because it is a quick-release formula, you should use it sparingly to avoid over-fertilizing. It is particularly effective if you brew it into a 'plant tea' to ensure even distribution and easier absorption by the soil.
To make a plant tea, mix the granular guano with water and let it steep for 24 to 48 hours, stirring occasionally. Once steeped, strain the liquid and use it as a soil drench to provide your plants with an immediate, easily accessible nutrient boost.
Yes, E.B. Stone Bat Guano is 100% natural and organic, making it an excellent choice for edible crops. It provides essential nutrients without the use of synthetic chemicals, supporting healthy growth from root to leaf.
Because this is a quick-release fertilizer, it provides a rapid burst of nutrients. You should monitor your plants' growth and reapply based on their specific needs, typically during the peak growing season, rather than relying on a fixed schedule.
