Some of you might enjoy reading this. I don't agree with every thing Bas writes but it is an interesting take on transplanting trees.
Wish I knew which of his statements are actually research based. When I transplant dormant trees I rarely water them in. The fine roots are already dead and new absorptive roots must regrow into soil.
He claims water helps coat the roots with soil particles. He seems very concerned of roots drying out but I don't believe this is such a big issue with dormant transplants based on my own experience (including accidentally leaving unplanted trees out in the sun for a day).
