Malus tree disease / pest help please!!!

Hi

I have a young Malus 'Red Sentinal' tree that has been planted for 2-3 months. I have recently noticed brown edges and holes in the leaves. Also noticed some small green insects on the leaves. Please can you again advise on what this might be and how to prevent it?

Please see picture attached.

Thanks.

 

Hi @G_MCD .

I was browsing through the tree section of the forum, and noticed that no one has responded to your question. How does your tree look now? I am assuming that the brown bits look browner, but that there are not noticeably more brown bits on the leaves?

The green insects you describe, are they aphids? If you have birds in your garden, especially tits, they will be delighted to remove these insects to feed their young. As they hang upside down from the leaves to find this for source, they can slightly crease or tear the leaves, especially when the leaves are young and relatively soft. This can result in superficial scarring on the leaves.

I hope this helps?
