Although I have a bit of gardening experience under my belt- I know virtually nothing about fruit trees. The tree in question is just in its second season. The end tips of all branches are exuding what appears to be a sticky resin which has soaked and curled the end leaves.....I really don't know what to do with it. There was some small cherries a few weeks ago- but nothing to talk of.
Would appreciate your help. Sorry I can't be specific with the name other than it seems to be from a dwarf variety.
It sounds to me like your cherry may be suffering from an attack by aphids and possibly a virus disease that they may carry.
I've noticed quite a lot of aphids in my garden this year, on sunflower, maple and budlea, to name a few!
The way I deal with it, is sraying with a strong jet of water to blast them away.
It took 3 or 4 attempts to rid them from the budlea but it seems to have done the trick, as it's now flowering well.
I've not heard of spraying fruit trees with Jeyes Fluid before Matheous .
I just use a strong jet of water from the hosepipe, that seems to work well for me.
