A lower-nitrogen formula that supports a natural tendency to grow in cool weather environments. This means less leaf scorch in summer?even in sun?and a smooth transition to dazzling fall color. A lower pH helps the roots take up the nutrients they need, and phosphorus and potassium deliver color illumination like you?ve never seen before. You?ll get all the brilliant reds, purples, and oranges that make Japanese maples the crowning glory of the garden.
