Finally, a fertilizer that is specifically blended for the unique needs of Japanese maple trees. Happy Frog Japanese Maple Fertilizer uses a lower-nitrogen formula that supports a natural tendency to grow in cool weather environments. This means less leaf scorch in summer, 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 brilliance like you've never seen before. You'll get all the showcase colors, including reds, purples, and oranges that make Japanese maples the crowning glory of the garden.
