Know before you buy
This formula is specifically designed for acid-loving plants such as azaleas, rhododendrons, camellias, hydrangeas, blueberries, and gardenias. It is ideal for any plant that requires a lower soil pH to thrive and bloom.
The formula contains 7% sulfur, which naturally reacts with the soil to decrease alkalinity. This creates the acidic environment necessary for acid-loving plants to effectively absorb nutrients.
The 18 strains of ecto and endo mycorrhizae act as a biological extension of the root system. They help the plant absorb more water and nutrients from the soil, leading to stronger root development and overall plant health.
For consistent results, apply the granular fertilizer every 60 days throughout the growing season. This slow-release schedule ensures your plants receive a steady supply of nutrients without the risk of burning.
Yes, it is safe for houseplants, provided they are acid-loving varieties. Because it is a granular, slow-release formula, ensure you mix it into the top layer of the potting soil and water it in thoroughly.
No, this is a granular, slow-release formula. It is designed to be worked into the soil or top-dressed around the base of the plant, where it will break down gradually over time.
