Learn About Your New Acer platanoides ‘Crimson Sentry’ - Crimson Sentry Maple

Acer 'Crimson Sentry' – Crimson Sentry Maple is a narrow, deciduous tree with a strong vertical habit and deep burgundy foliage that holds colour throughout the growing season. Its compact form (9–10m high × 3–4m wide) makes it ideal for spaces where height is needed without lateral spread.

They look excellent in driveway lines, tight verges, or as vertical features in formal gardens where structure and colour are key. Unlike broader maples, this cultivar offers a refined, columnar silhouette with minimal maintenance and reliable colour retention in full sun.

Well suited to urban settings, narrow beds, and modern designs requiring vertical definition and seasonal contrast.

Post Planting Care

When planting a new tree or shrub, proper watering is essential to ensure healthy establishment and long-term growth. Follow these guidelines to give your plant the best start:

  1. Immediately After Planting:
    Water generously right after planting to settle the soil around the roots and eliminate air pockets. This helps the roots make good contact with the soil.
  2. First Three Months (Establishment Phase):
    The initial three months are critical for root development. Water deeply twice daily (morning and evening) to encourage strong, deep root growth.
  3. Irrigation Systems:
    If using an irrigation system, adjust it to provide adequate water during the establishment phase. Ensure the water reaches the root zone without overwatering.
  4. Weather Considerations:
    Adjust watering based on weather conditions. Increase frequency during hot, dry periods and reduce it during cooler, wetter seasons.
  5. Ongoing Care:
    After the establishment phase (3 months), gradually reduce watering frequency but ensure the plant receives consistent moisture, especially during dry spells.

Long Term & Ongoing Care

Caring for Acer ‘Crimson Sentry’ Maple

  • Watering: Maintain even soil moisture, especially during prolonged dry periods.
  • Pruning: Trim selectively to maintain shape and eliminate undesired growth.
  • Mulching: Add mulch around the base to maintain soil moisture and suppress weeds.
  • Monitoring: Regularly inspect for pests and diseases, and act promptly if detected.
