You are probably going to regret having posted to this topic, because I am going to “hound you to death” for pictures and information once it leafs out and fruits. I see at your location (Wallkill, New York) you get freezing temperatures in early October, which seem to progress gradually into hard freezes by late October/early November…Maybe this gradually “deepening” allows the ‘Pakistan’ to acclimate to such a cold climate. I have noticed that my mulberry trees here in Northern Florida do not go into a fully dormant state, noted by when I cut off a branch in the dead of winter, it will still have some sap flowing…A very hard freeze occurring in this state will severely damage the tree. I am guessing, if you cut a branch of your tree now (in winter), no sap would show at the cut end.
I may order one of Stark Brother’s ‘Pakistan’ to evaluate it close up, just to be sure we are both referring to the same plant. Was the fruit of the mother tree what you would expect for a ‘Pakistan’ (~3" fruit)? Thank you so much for posting…It has opened up a whole world of possibilities for the lowly mulberry.
