Our Experience

Experience at Great Hill

On Great hill we feature Pyrus calleryana ‘Aristocrat’ in our English garden. Where there were six once planted, only one remains fully intact. We’ve experienced the all too common pear pitfall, splitting. Due to being weakly wooded and having poor branching structure (tight crotching and many branches developing along a common length of trunk), these trees can literally split in half following a strong storm or wind event. The other issue with the callery pear is its invasive tendencies. As such, there is a push in the industry for selecting flowering alternatives to this tree.
