Prune or coppice Mimosa/acacia?
The acacia/mimosa tree in the garden of my new house was blown over and leaning at 45 degree angle, was staked to secure and to our surprise, survived the winter and is flowering. I'd like to prune the top to reduce the windage and train it straighter, as it is overbearing other plants. It can't be forced upright, so should I pollard it, or can I start again by cutting it close to the ground. There is very little in this new garden, so it would be good to save it.
