I have a 3 year old plum tree who has problems. The tops of the leaves
are very sticky and underneath there are what look like aphids, I
suppose that I have answered my own question but if they are aphids how
do I treat a tree or has the damage been done, some leaves are curling.

I'm afraid that this seems to happen most years especially in this type of
hot weather.
Whilst it is a pain & unsightly, it doesnt seem to have much effect on the
tree & it's fruit production.
My victoria has been planted 15 years now & has been very productive on 12
of them.

Good to know that this is a comman problem, I was thinking about pruning
some of the branches where there is no fruit - not that there is much
anyway - will the bugs spread, does anyone think it would be harmful,
must buy a book on fruit trees :-)
