Any thoughts on what might be causing this Leaf distress? Occuring on all new growth.
Leaf curl, yellowing
Occurs on new shoots
I don’t see any evidence of mites aphids or whiteflies…
I have Japanese plums about 30 yards away and they do not have the symptoms
Thanks!!
Looks normal to me

Looks like new growth, a little bit chewed on
The new color is normal and not disease!
Here in NY by this point in the season, leafhoppers usually slow and stop growth of E.plum without pesticide intervention Your shoots don’t look like they are suffering yet, however. but photographs only take me so far- there does appear to be some browning on the 8th leaf down of the left shoot-1st photo. They are very small and elusive and I can only see them when I disturb a shoot and they hop off.
I believe them to be a key destroyer of grafts that seem to take and then dry up after growing and merging tissues on E. plums and apples. They can be managed with pesticide but keep coming back until very late summer. At that point, there is often a late surge of growth on affected trees.
Once trees are established they may actually be an asset because they reduce rank vegetative growth and keep sunlight on the leaves that serve fruit. They don’t seem to feed on hardened leaves. When they need to be controlled only the very tips of shoots need be sprayed- just like OFM.
Here they seem to mostly affect apples and E. plums.

FWIW my plums all grow out that way with new tip growth
Back to the Stanley tree.
Looking for an opinion I think the Stanley tree is way too dense. Seemingly too lush. Should I try to thin it out if so when?
Sure can’t see thru it.
And I can’t seem to effectively spray it against the aphids since there’s so many leaves.
Thanks!

Those most visible are snapdragons I planted from seed last year they seem to be almost perennials.
Back on topic I decided to trim back severely the Stanley plum.
Now i can get to aphids. Unfortunately I discovered some black knot on a few branches.

Yes,they can be pruned now.It’s may be easier to do it,when somewhat dormant,because the branches are more visible.
Some of my Stanley’s have dark blemishes on fruit, but only on bottom. Seems to be superficial only.
I’m looking for an opinion why that might be. I thought perhaps All seasons dormant oil spray or bonide tree spray settles on bottom, like a drip and causes what I hope is just a discoloration and not harmful to the fruit.
thanks!
