Sudden dead leaves on Prunus Kojo no mai

I have had a kojo no mai tree in a pot for a year or so and it’s been great. I’ve recently had vine weevil problems in other pots, so have just put down a thick layer of gravel to help stop the larvae.
However this week I have noticed that some random branches of leaves are dying. I am hoping it is just warm the weather, perhaps I’ve not been watering it enough, but it seemed very sudden and only certain branches. I’m really hoping that I wasn’t too late with the gravel, and that the problem is caused by vine weevil larvae 😐

Can anyone shed any light on the odd way that only some branches are effected? Some in direct sunlight, some not. Just under the dead leaves there are new buds which gives me hope?

Many thanks

    I had this shrub in the garden for fifteen years and every year some branches died off.

    Same as Joyce here, some leaves and short branches seem to die within a month of flowering but then later in Summer more seem to open.

    It does seem to be either a case of not enough water or too much hot sunshine. I've now moved mine into a shadier position and am keeping an eye on it, watering frequently - it's a pretty boring looking plant once the flowers are over I think.

    Thanks for your comments everyone.

    I think you’re right Lizzie, not that interesting after the blossom which is a shame! It is in a west facing position in a relatively small pot which is in full sun itself, so it probably is suffering a bit with all this hot weather. I’ve been giving a good dousing of water every day and there doesn’t appear to be any more dead leaves since.
