Hi
I was reading in Naka that Ammonuim sulphate can be given sparingly to
pines when they have a yellowish tint of teh needles..
my pentaphilla is always as such in this period of the year
what could I do to prevent that and when is teh best time and
quantitioes to be given or if exists something less *chemical *
producing the same effect

If the tree "always" is like this in winter, that probably means
that's how it is supposed to be. I don't think I'd doctor it
with anything if the tree is otherwise healthy.

Even the pines in my pasture (P. taeda) always look a little
dull in winter. I think that's what passes for dropping leaves.

Ditto. The pines in my area (mostly P. strobus, Eastern White Pine) always dull in
color in the winter. From what I've seen most needle evergreens (most broadleaf
evergreens too, for that mater) turn dull in winter.
