You've dug a wide hole, set up a sturdy stake, and prepared nutrient-rich organic soil to nourish your tree for years to come. Great job so far.
Now comes the crucial step: how deep should you plant it?
The root collar—the flare where the trunk meets the roots—should sit level with the ground surface after backfilling and firming the soil. This ensures healthy root development and prevents issues like girdling roots or rot.
For container-grown trees, cover the root ball with just 3 to 5 cm of soil.
To check the level accurately, lay the shovel handle across the hole as a straightedge guide.
You might wonder: If I create a watering basin this summer, won't the shallow root collar be exposed and vulnerable to sun damage?
Spot on—that's a risk. Skip the basin at the trunk. Instead, form a circular berm 30 to 50 cm from the base. This directs water to the roots effectively without excavating near the trunk.
