When and how to prune a rowan. I have a 10ft rowan in my garden. It is about 3 years old but is too tall for its trunk. Typically it was sold in the garden centre too tall and thin. It suffered badly from the strong winds in May this year and I have had it staked since then. I want to reduce the height of the tree by a third to try to balance the height with the trunk making it more stable. The top third that I plan to remove will be about 6cm thick at the main trunk.
Any tips on how to do this? Will it need sealed or should it be OK to leave the wound open.
