Hi Gerry, I noticed earlier in the week the damsons are starting to ripen, but some of them seem to have what looks like rust spots – could this be the brown rot – or do i need to do a little more investigating of the damsons?The trees were in the garden when we moved in 5 years ago and last year there was a bumper crop, this year there is a lot of fruit on the trees, but i am worried about the brown patches on them.If it is – what do i have to do at this stage?Kind Regards ,Lorraine Keely
