I would like to put some Japanese Black Pine in the ground in zone 5b. I read varying hardiness for JBP, some say 5 some 6 or 7. Does anyone in zone 5 have JBP in the ground? Any issues?
I grew them in zone 6 MA for years without an issue...the landscape and potted trees saw below 0 F more then a few times. I've heard they are hardy in the ground to zone 5 but are very susceptible to wind burn so placing them out of the prevailing winter wind is a good idea.
What zone are you?Not this far north.
What zone are you?
I'd give it a shot. I have a JBP I purchased at NEBG years ago that was supposedly field grown in southern ME. Sited appropriately, I think you'll be successful.Good stuff to think about. At the very least they will be marginal here. I might try anyways, definitely with nothing more developed than seedlings so I am not risking anything.
What surprises and, may I say, troubles me, is how some really smart and obviously educated people, can only come up with reasons why something cannot be done and seem void of ways, or interest in finding, ways they can be done. Sorry but that is the message that is being sent here.
If Michael Dirr says it's a zone 5 tree, it's hardy below -10 F. The trees I grew saw temps of -8 F several times without damage.
Otherwise, you end up with a tree that could do great for 20 years grow to a substantial size die in a terrible winter and fall on your house.
