What Tanis writes is true. I've noted the same and I believe thick (somewhat) 
dry mulch could delay bloom. 

Now for the reverse. The American persimmon are one of the last trees in this 
area to break bud. I've always wanted to see if regular watering of (solar) 
heated water beginning maybe 4 weeks before normal budbreak will bring on 
earlier bud break.  

Doug Campbell, Ont. Canada, some years back reported he did such with two 
transplanted persimmon trees by coiling up several lengths of garden hose around 
the tree and at intervals emptied the heated water around the base. He 
reported they broke bud earlier than non transplanted trees within a few feet. In my 
experience it is unusual for recently transplanted persimmon trees to break 
bud before those established. One advantage these two trees must have had was 
lose soil from the transplanting and am suggesting the warmed water was better 
able to penetrate into the roots thus enabling warming.

I'd like to see some member of this net with more time than I and with a 
surplus of garden hose duplicate his findings except using established small trees 
not recently transplanted. Someone on sandy soil would likely be best. If you 
are in zone 5, now is the time to start the experiment.
