Can I save my Japanese cherry?
I have a Japanese cherry prunus serr shirotea in my front garden. It hasn't grown much in the 10 to 12 years it is there but I think it is not meant to and is fine for a small front garden but some of the branches now have no leaves and the leaves are turning in on themselves. The house builder also put these in other gardens where I live and they look a lot healthier than mine! It did flower well in April...lovely for those 2 weeks. Can I save it or do I just replace it? It is grafted if that is relevant?
