A problem with pines
« on: June 10, 2010, 10:02 AM »
These pics are closeups of the spring candle needles on my JRP 'Aurea'. The needles are a whitish pale color. Older needles do not show this. I also have a Mugo 'Aurea' that is showing the same thing. They are both in a inorganic free draining mix of lava, pumice, haydite mix with slight particles of charcoal(close as I can get to Boon's mix). I've noticed it has gotten progressively worse over the past 2 weeks. I am puzzled as to what is going on with both trees. I am not seeing any insect infestation on the candles or the tips. No webbing of any kind to indicate mites, pine tip moth larva or others. I apologize for the fuzzy pics as my camera was inside and bringing it out into 90% humidity made the lense fog up. Anyone have any ideas or suggestions? Thanks much!

looks like fungus, spray with Daconil or some other such thing, if the needles are dead and loose, pull them and put in trash (burn if possible). John

They're not loose. Tried to pull them off already.

Sprayed them both and all my trees with Daconil and Triazacide(pesticide). Figured I'd do both at once since I was needing to spray for insects again. I used a systemic back in early spring so I can't use that again til next yr. Use it once every 12 months. Hope it took effect before these pop up thunderstorms came, and are, rolling through.
