Jack's Classic Acid Special

Acid-loving plants, or acidophiles, are species that thrive in soil with a lower pH level, typically between 4.5 and 6.0. Common examples include azaleas, rhododendrons, blueberries, hydrangeas, gardenias, and many ferns.

This formula is perfectly safe for both. Because it is water-soluble, it is easy to dilute for indoor containers just as effectively as it is for outdoor garden beds.

This fertilizer is engineered to be absorbed by the plant in two ways: through the roots when watered into the soil, and through the leaves when applied as a foliar spray. This allows the plant to access nutrients immediately, which is especially helpful if the plant is showing signs of deficiency.

The 17-6-6 ratio indicates a higher concentration of nitrogen (17%) compared to phosphorus (6%) and potassium (6%). This higher nitrogen content is specifically designed to encourage lush, green foliage growth, which is often the primary goal for acid-loving ornamental plants.

While this fertilizer supports the overall health of acid-loving plants, it is not specifically a color-altering agent. However, because it helps maintain the acidic soil environment that hydrangeas prefer, it can indirectly support the conditions necessary for blue-toned blooms.
