This flowering cherry tree is planted in a walled garden in Hove, Sussex. It is at least 30 years old and flowers regularly each year. In the last few weeks it has shed almost all it leaves which it wouldn’t normally do until autumn. There doesn’t seem to be any sign of disease or insect damage and has been regularly watered. Is this just due to the dry weather this year and is there anything that can be done to rescue the tree? Thanks.
This is, actually, more common with wet soils than with dry. Treating with a fungicide will be appropriate from here. This article will help:

out The tree has been in situ for approx. 25 years with no problems in fact this year when it flowered it gave the best display it has ever had. Someone has suggested applying a 'mulch' around the base of the tree but can you suggest any other courses of action as I don't want to lose the tree if possible.I think that it could be a ' pathagen ' but I really have no idea any assistance will be gratefully appreciated.
Gummosis: that "amber liquid" is sap and normally, you have to wait for the tree to heal but look for signs of borer insects:

I want to plant a prunus amanogawa in our town square to celebrate the community spirit shown by people in the town during the pandemic. Someone has suggested that the roots can cause problems to paths and walls.A local horticulturalist has said that they will cause no more problems than the lime trees that border the square. What do you think?
I didn't find any reference that said they had aggressive roots but they do sound like they are high maintenance as well as short lived.
