While the tree supplied was perfect no planting instructions were sent with it. It was tightly bound on a long cane so using normal practice I removed the cane and staked low down to keep the roots firm while allowing freedom to bend. Next morning it had been reasonably windy and the tree was bent over. I spoke to the nursery who seemed to thing it should be staked more and then sent planting guidelines. I staked the tree higher up and went away for a few days during which time a storm came through. I returned to find the top 2 metres completely snapped off. My wife and I are both experienced gardeners and used normal practice and our experience for planting. We owned woodland for many years. The planting instructions gave different advice and since these were not sent out with the tree we are of the opinion that the nursery has to share some of the blame for this. Had we had the instructions on delivery we would have contacted the nursery to clarify and done things differently. Our beautiful and costly tree is ruined, hopefully it will continue to grow and eventually come back to a fastigiate form.
