What's wrong with my Picea Pungens Procumba? (6 Replies)

Posted April 23, 2017 at 9:26 am

Hello,
My beautiful picea pungens procumbens, planted 3-4 years ago, has been losing needles since last summer.
Any idea what the problem is and how I can save it?
Much thanks,
Lisa

where do you live, Lisa? That is one very unhappy spruce. My best guess right now is Rhizosphaera needle cast, a fungal plague that tortures Rocky mountain native trees that aren’t living in the Rocky mountains.
You can control it by fastidiously removing any dead foliage on or around the plant and spraying with anti-fungal products in late winter, particularly before a prolonged cold wet spring. Good luck.

Hello David,
Thanks so much for your quick response! I forgot to say I’m in Boston, zone 6. It’s early spring here so I’ll try spraying with anti-fungicide now. Is there a particular one you recommend? I will cut back all the dead foliage. Do I need to treat the cuts?
Much thanks,
Lisa

No need to treat cuts. They will heal on their own. I recommend contacting your county extension to see which product works best in your area.

This is a small specimen in which the top looks healthy to me. The possibility cannot be dismissed that an animal like a dog could have urinated on it – possibly more than once. That is the kind of damage I have seen happen. If you suspect that could be the case, I would recommend putting a decorative wire garden fence around it. I do that around my trees since I have discovered it also protects them from errant lawn mowers. 🙂

Lisa do you have an update for us? How does it look?

Just heard from Lisa. She cut off the dead areas and gave it more water. Looks like this one may have been suffering from that New England drought. So far, so good. Lisa, keep us posted!
