United Kingdom 
I have a plum tree which I bought 2 years ago. This year there is lot of fruit but quite a lot have small brown marks on the young fruit, growing bigger as the fruit grows.
Can you please advise what this could be.

Someone else will tell you what causes the marks - I'm pretty sure its insect damage of some sort, but I can assure you that the plums will still be edible. You may find that the patches ooze a bit of yellow liquid that sets solid when the plums are bigger, but just cut that part off.
