Possible unseen cause of failure to fruit.

I'm seeing this in two trees. My nectaplum, and a Santa Rosa plum. I think the latter will die, the nectaplum will make it, but all scaffolds are dead. i will have to redevelop new ones. I just formed a new central leader on this tree last year, it's 2nd leaf. The torture never stops.

Drew-

I'm watching my Hunza apricot that i think has this damage. The leaves are dropping, some have yellowed and fallen off, but i'm still seeing small new shoots...lower on the trunk, everything is fine (growing lots of shoots very low)... I don't really care if i lose the tree, so i should just cut it low as possible and then graft it over to Satsuma... The tree of mine is probably 6+ years old.

I just read somewhere that -17F was peach tree killing damage in Michigan this past winter. But can't find that report right now. Lots of areas got that cold.

After watching my Puget Gold apricot for a few weeks here (i have several stonefruit grafted to it), it looks like a main branch may have been damaged...seeing all the signs (wilting leaves/yellowing/very little growth)...this is a south facing branch...the other 2 main branches look good (lots of growth)... I may have to remove this branch...

Frank:

Both my reliance peaches are leafing out so poorly after this winter that I am cutting them down. One was 8 years old and the other 9 years old. I will start over.

The odd thing is that I sell fruit trees at the nursery I work at. Some clients bought Reliance peaches and have them situated close to Lake Michigan (Milwaukee area) and came thru great. Their flowered well. Another client bought one from me 3 years ago and is near where I grow mine and his flowered well. Mine are as good as dead.

Did age of tree have anything to do with it? Not sure.
Another client bought a Contender peach from me two years ago and got a nice crop last September. This year his tree is dead.

I presume some sort of micro-climate or somewhat sheltered areas are the explanation as to why some peach trees lived yet others died around here.

My blackgold sweet cherry looked ok when I pruned in March. The flower buds never opened this spring but it
leafed out nice. I thought I was lucky as at least the tree
survived. Two nights ago I checked on my orchard and found most of the leaves wilting on the cherry and the bark on the branches shriveling up. Cambium no longer green.
Delayed winter injury too?

spartan yes that's winter cold injury. The trees can leaf out normally and then collapse in the first heat wave.

Which would be right now.

Yes...that is winter injury.

...i've got good growth on 3 of the 4 main branches (i thought it was 3, buts its 4) coming off the trunk of my Puget Gold (not sure of the rootstock).... The one branch is just not showing anymore new growth and the leaves are yellowing some, drooping ... its weird, because on the main trunk, it has a brand new shoot coming out right below the (what i think) dead/dying branch. \

I also removed a 6+ year old Hunza apricot on Citation...it did have new shoots coming up low on the trunk (not citation, above the graft), but the tree wasn't worth saving in my book so it will be firewood now.

I'm going to be very careful what i put in the ground. I'm starting to wonder if Tomcot is hardy enough for my climate. I removed 2 of those last year (with a milder winter then this past one) showing all these same symptoms.... I think i'll move my apricots into pots.
