Mugo(?) pine yellow-brown needles
I've been enjoying your plethora of knowledge for some time now. Sadly, the first thing I wat to post is about my mugo (I guess) pine. Early August, when I put it in the ground it had beatifull yellow-green colors and very dense foliage. By the end of september, the older needles started to go more green and eventually brown, especially at the tips. Since then more needles have gone brown and it has lost many of them. This is more obvious on the north side of the tree.
I've uploaded some images on my site (which is irrelevant to conifers :-) ) but please see them for any insight to what is the cause. I couldn't bring the images down to 60kb and still be viewable so I posted them there.
Also an identification of the cultivar would be great.
Thank you in advance,
