HEPTALOBUM RUBRUM UPRIGHT JAPANESE MAPLE Homeowner Growing & Maintenance Tips
- Recommended Soil: Prefers rich, loamy, well-drained soil. Performs well in average garden soil with added organic matter that is slightly acidic to neutral in pH (5.5–7.0).
- Sun Exposure: Grows best in partial shade, as the best foliage color develops with morning sun and afternoon shade in hot climates. Tolerates slightly higher sun exposure in cooler regions.
- Irrigation Needs: Requires consistent moisture, especially during the first 2–3 years. Water deeply once or twice weekly during dry periods. Avoid soggy or poorly drained soils, which can cause root stress.
- Feeding & Nutrients: Apply a slow-release, balanced fertilizer in early spring and mulch with composted organic matter to conserve moisture and enrich soil. Avoid heavy nitrogen fertilizers, which encourage excessive green growth.
- Pruning & Maintenance: Prune lightly in late winter or early spring to shape or remove dead wood. Avoid heavy pruning, which can spoil its natural form. Low-maintenance once established, with excellent cold and heat tolerance.
