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
Thanks

Theo:

I NEVER apply Ammonium Sulphate to my pines.

If you are experiencing a discoloration during the winter,

it may simply be specific to the cultivar of Japanese white pine.

For example, Kokonoe has a tendency to turn yellowish during the winter,

It is a kokonoe . thanks for the answer

with its greenish color returning in the spring and summer.

Be certain that you soil is fast draining and that you or mother

nature is not overwatering the tree.
the soil is ok and I do not overwater


In the spring, apply chemical (20-20-20)

I have Peters 20-20-20


fertilizer as well as a modest number of slow releasing fertilizer cakes.
I have them as well

Thanks a lot for your information , so all is normal
