How To Grow Banksia integrifolia 'Sentinel' In Different Soil Types

Optimizing Soil for Robust Growth and Coastal Resilience

Watering Requirements After Planting

When you plant a new tree, it's crucial to give it the right start by ensuring it receives sufficient water. Here’s a general guideline for watering your newly planted tree:

  • Immediately After Planting: Water your tree generously right after planting your Banksia integrifolia 'Sentinel' to settle the soil around the roots and eliminate any air pockets.
  • First Three Months: The initial three months are critical for the establishment of the tree. During this period, the tree should be hand watered twice daily, in the morning and evening. This helps the roots grow deep and strong.
  • Irrigation System: If you have an irrigation system, adjust it to ensure the tree gets adequate water during these first months.
  • Adjusting to Weather Conditions: Always consider the weather conditions and adjust your watering accordingly. In hotter and drier periods, additional watering may be necessary.

Consistent attention to your tree’s watering needs during this initial period will help ensure its healthy growth and long-term success in your garden.
