[IBC] ammonium sulphate
Theo Writes:
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, 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. In the spring, apply chemical (20-20-20) fertilizer as well as a modest number of slow releasing fertilizer cakes. Cordially, Michael Persiano members.aol.com/iasnob ************************************************** ****************************** ++++Sponsored, in part, by Boon Manakitivipart++++ ************************************************** ****************************** -- The IBC HOME PAGE & FAQ: http://www.internetbonsaiclub.org/ -- +++++ Questions?
