I have a small tomcot apricot tree, about 7ft tall, and the whole thing Y-shaped with the main trunk being only about 8 inches off the ground before it forks.
This year (I don't know how old it is) it bloomed very nicely, and has since produced one single apricot.
Two days ago I noticed that the leaves on the left hand fork were looking a bit saggy. This has continued and all of them have now dried up and wilted. I looked aroudn the internet for causes but there seem to be plenty of apricot leaf wilting diseases out there. I cut off the top few inches of the dead fork with secateurs and found that there is still sap in there, albeit rather pale sap.
Should I saw off the whole of the left fork? It's one main shoot and another smaller one. The right hand is much bushier and I am concerned whatever has got the LHside will now spread.
