Help with funny looking stone fruit leaves
One limb of a Minnie Royal cherry broke bud strangely this year. I thought perhaps it was die-back, but now the odd buds are actually pushing new growth--which also looks strange:
The leaves are stringy and oddly colored on the margins. Some look like they have been artistically nibbled. I'd hate to lose the limb as it will unbalance the tree, but if this is some kind of virus, I don't want it to spread to the rest of the tree. If it's a fungus or pest, I'd like to know how to treat it.
Next come the plums...Old growth looks fine but new growth is showing yellowing and some leaf malformation:
These are what the more mature leaves of the ersatz "Satsuma" I posted about
earlier look like:
Finally, I did some apricot bench grafts this year and have not had a lot of success. Only one (FloraGold) has really taken well:
The only other surviving graft is this sad-looking GoldKist:
That was grafted in late February and that is all it has done. The leaves look pretty sad, but it won't die (yet). I guess my question is whether there is a disease involved that could be weathered (like my peach bench grafts with the near-fatal PLC last year which now look great after a lime-sulfur regimen) or whether I should just cut my losses and regraft. I don't have any more GoldKist wood, but I do have some additional Blenheim which is what I have been using on the other bench grafts that failed. I had hoped for 4 different varieties, but at this point I just want to be sure I have four trees that can go in the ground in late Summer. I can always top work later while the trees are small.
