Pear tree stems turning black and other issues:)

etakemail

Hi, I bought 3 mini grafted fruit trees 3 years ago, plum pear and apple. I’ve never had any fruit on them but they were totally neglected, not fed in pots so no surprise.
last year the plum tree blossomed and got very small fruits (tick tac size) then one day went yellow and fell off. Did I overwater them?

I fed them all last year and the pear and plum now have very small fruits starting but on a lot of the stems to the fruit on the pear tree they have gone black and sickly looking there are small patches of those little green bug things (greenfly?) and I pulled off a few leaves at the end of one branch that had gone black and there was a bright green caterpillar in there! The cheek of it hehe

Don’t even ask about the poor Apple tree hehe

Ive just taken loads of pics, some of the black stems on pear tree and the branch end I took the black leaves off , where caterpillar was. Some of the plum tree, leaves are starting to curl slightly. One of the Apple tree which has those green bugs and some of the green and black bugs which are on some shrubs. Oh and one of a spider web full of babies
I can’t get the photos in the right order sorry

You May have gathered my knowledge of gardening is something to be desired hehe
I also have problems with the little green bugs that colonise on new growth and the little black ones that look similar, and white powdery mildew but that’s not where the trees are.
I have made some garlic water to try using on the pests, any suggestions or tips on using it or for any of my issues would be greatly appreciated

Thank you for taking the time to read this

Looking for something else,  l came across this that seems to have slipped through the net. It may be too late, but l will bump it up.
There seem to be a lot of pear problems at the moment!
