It sounds like your persimmons are just like our wild apples--no fertilizing, no pruning to speak of, just give them sun and step back. That'a just a great example of the largest paybacks for our efforts are accentuating stuff that already works on our individual properties and areas.
Thanks for the late freeze tip on the plum blooms; That explains why there are seldom any plums seen around here.
I paid extra attention to the use of Blackberry and saw the the deer eating the green leaves a few times during hunting season. As far as winter use, after checking several stands last week I'm afraid its use is similar to what you have witnessed at your place. There is some browsing going on but it is negligible--not at all like the Red Osier Dogwood which gets it's tips close to 100% browsed;The blackberry tips are not more than 5% browsed. When there was very little blackberry it seemed like it was eaten more but now that there are larger samplings to observe it is obvious its not a winner here. It was disappointing;I was hoping it would be better winter utilized. Will be coppicing some of the taller dogwood over the next month and ignoring the blackberry I guess.
Its great that you enjoy the coyote calling. For a few people around here it is their main hunting activity and is mostly done at night here.
