I live in a rural hilly zone 4 area. We have mostly oak and maple on and
around the property with a sprinkling of other trees. The few coniferous
trees we get have a high die off rate and I don't know why. Most recently a
7' pine turned brown from the top down. Now a neighboring pine is doing the
same. A few pins per branch are brown, but the top is completely brown. The
stem and bark seem fine. We had a rough winter last year and I understand
the trees had been stressed by lack of rain in the fall. This however has
happened since spring and we've had plenty of rain. I haven't noticed any
particular bug infestation and the deciduous trees are just fine.
Any ideas what may be going on?
Thanks in advance,
Sorry to hear about your troubles. I am not very knowledgeable on this,
so I won't venture a guess. However, I can tell you that you would find
accurate info. by tracking down a local/state agricultural extension.
You should be able to send samples of your soil and evergreen to the
extension, and have them give you an exact reason to your troubles.
They would also likely know if there is a disease prevalent in your
neck of the woods.
Maybe someone out there in zone 4 knows the closes agric. extension???
A little more information. What size are the trees? How long have they
been where they are? What types are they (one is a pine, what kind of
Has this spring been wetter than normal. My guess is too much moisture.
Also keep in mind that many such trees do drop needles every year, usually
spring to early summer.
Conifers, pines in particular, can get stressed by periods of drought followed
by periods of lots of rain. A couple of years ago we had a very wet winter and
spring that followed several seasons of extended summer droughts. Pines failed
by the dozens, including many that were very well established. The effects of
drought/excessive water are not necessarily immediate - sometimes it may take
several months or even a season or two before you notice the trees starting to
fail. To be sure and to discover if there is any remedial action you could
take, you might want to consult a qualified arborist for advice.
