Newly planted Himalayan Birch

Hello!

On another thread I discussed my buying and planting a Himalayan Birch. It's in the ground now, supported by H frame (see photo).

It was delivered with a full length bamboo cane, running from the root ball to the tip of the leader. The tree is 11/12 feet, I think, and I live in a windy exposed spot near the coast. All that said, should I remove the bamboo, because the tree doesn't move even in strong winds, and I fear it won't be building any strength or resilience?

Thanks in advance!

 

Modern thinking seems to suggest you stake a bit lower than you are in the picture, allow the trunk to bend but stop the roots moving.

Cant really see any reason to keep the bamboo in place.

 

Thank you. I suppose the only reason I had the bamboo left in place was to protect the tree in high winds. But I see now that it's best to let it feel the wind..
