We have mentioned before our Mediterranean pine tree grown from seed (it is now 25 years old) the roots were pushing up the paving slabs (now resolved)-Can we prune the highest branches that reach up in order to control the height without harming it as it is now casting quite a large shadow on our garden and our neighbours? Can we do this now or should we wait until later in the year?
