Know before you buy
The 3-12-12 ratio indicates a low nitrogen content with higher levels of phosphorus and potassium. This specific balance is designed to shift a plant's energy away from leafy growth and toward the development of flowers, fruits, and strong root systems.
While this product is specifically formulated for flowering plants like roses, perennials, and shrubs, the high phosphorus and potassium content can also benefit fruiting vegetables like tomatoes or peppers. However, it is not intended for leafy greens where you want to encourage foliage growth.
Simply sprinkle the granules evenly around the base of your plants, avoiding direct contact with the stems or foliage. Always water the area thoroughly after application to help the nutrients penetrate the soil and reach the root zone.
Humus improves the soil's ability to hold moisture and nutrients, while beneficial microbes help break down organic matter into a form your plants can easily absorb. Together, they create a healthier soil environment that supports more vigorous root growth and better overall plant health.
This fertilizer is best applied during the active growing seasons of spring and summer. It is most effective when used as your plants begin to set buds or enter their primary blooming phase.
