Learn About Your New Eucalyptus microcarpa - Grey Box

Eucalyptus microcarpa, known as Grey Box, is a robust medium to large native eucalyptus highly valued for its drought tolerance, habitat benefits, and low-maintenance nature. Growing 15–25 meters tall with a broad domed canopy spreading 10–15 meters, this evergreen tree features narrow lance-shaped grey-green leaves and a gnarled trunk with rough grey bark, offering both character and resilience.

Ideal for full sun locations, Grey Box thrives in well-drained soils, including clay loams and poorer soils, and requires minimal water once established. Its creamy-white flowers from late summer to autumn attract birds and pollinators, enhancing biodiversity in rural and urban landscapes alike. This tree looks excellent when used as a shelterbelt, shade tree, or for habitat restoration, especially where longevity and toughness are prized over rapid growth. It’s a powerful, elegant choice that stands strong in harsh conditions while adding natural beauty and ecological value.

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.
