Himalayan Birch

Hello,

This tree is known to have a shallow root system.

I am thinking of putting in a circular root barrier when planting the Himalayan Birch to avoid uplifting paving stones etc.

Deeproot manufacture different depth of barrier.

Depth
1. 30 cm
2. 46 cm
3. 61 cm
4. 91.5 cm

Which do you recommend please?

    the deeper the better, but be aware that it will make your tree unstable in heavy winds - you're basically putting it in a pot in the ground
