We've recently planted two cherry morrello (bush colt) trees in out garden (East/South East facing) along with two types of apple tree. We planted them approximately 2/3 months ago, and they all seem to be thriving very well so far. They're well watered and the soil isn't heavy as far as I can tell (certainly not clay).
Following a lovely blossom, the green leaves started to grow in abundance. One cherry tree seems to have more green leaves whilst the other already had cherrys growing in abundance (50 ish so far). The trees are in the same spot so shouldn't be any difference due to the way they are facing. Tree heights are 1.5 - 1.8 metres at the moment.
Over the past week or so I've noticed two branches on one tree has lost it's leaves - they've gone brown and shrivelled - any cherries on this branch have also shrivelled. One branch on the second cherry tree has gone the same way (approximately 5/6 branches on each tree). There is also evidence of some kind of sap (one hardened and clear, the other a darker coloured sap).
I haven't got in touch with the nursery as yet and I'm inclined to believe it's down to early teething troubles/shock of the planting process...another part of me leads me to believe it might be worth pruning these brances right down (and it would really have to be right down to the trunk given the whole branch seems 'affected').
On the pic below you can see one of the branches in quesion - you can also see the cherries behind (lack of leaves on the branches with the cherries however!)
The second pic shows both of them together - the tree in the forefront seems to be less affected (only part of one branch has the brown leaves), has less cherries but far more leaves.
Apologies if I've missed any information out.
