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 River Oak

  • Watering: Water frequently until established, then as required. Prefers moist conditions.

  • Pruning: Prune as necessary to shape or maintain size.
