We bought a photinia red robin, grown as a full standard sized tree around 6 months ago and planted carefully with the help of the nursery we bought from.
When we had the freezing weather over winter it's leaves all started drooping, then as spring arrived they all fell off 🤯
It had a full canopy of unblossomed flowers, which I've cut off to try to allow it to put the energy into new leaf growth rather than blossoming.
I think it might have fireblight or some kind of fungal infection as the last round of new leaves all turned crispy before maturing. I've applied a fungus treatment in the hope it works.
Have I got any hope at all? Is there anything else I should be doing?
