The browning needles are likely caused by too much water. Pines like dry
conditions. Some species of pine are more affected than others. If you
think there might be a fungus disease starting up, you could rake up the
dead needles and dispose.

What can I do to protect two- and three-needle pines from Diplodia blight?
A: Diplodia blight of two- and three-needle pines, caused by Diplodia sapinea,
has been abundant this growing season. The disease primarily occurs on Scots
(Pinus sylvestris),
It may be due to the extreme rain we’ve had this season. Mold and all kinds of
things are growing, and the trees don’t have the chance to dry out and clear
the parasites. They may do better when the other leaves in the woods fall and
the sun can really get to them finally.

The wooly adelgid is expected to kill 80% of the hemlocks in the country
and Canada (it does not seem to affect pines as far as I know but I'm not a
specialist). The hemlocks that survive adelgid are immune to it - a lucky
hemlock or rather a specimen enhanced by human research and doing.

Over the years we have spot treated our hemlocks with horticultural oil on
lower limbs when we see the bugs. We haven’t done it in a couple of years. I
think the balance has been won here (fingers crossed).

I appreciate others noting it here. I was wondering whether my taking note
of this was a consequence of moving my workspace upstairs with a direct

All pines lose a third of their needles every year. It could very well be
part of their natural process. It's hard to tell from the picture because
there's a lot of greenery in the back.
Do you see any signs of complete browning of the tree? That would signify
the tree dying.

I was about to email with the same question. I noticed the
downward-facing needles tend to brown more than upward-facing needles.
In addition to the common native white pines, an ornamental Japanese
umbrella pine is also affected.
A half mile away the pines all seem healthy.
