Jakobsen Mugo Pine (4 Replies)

We have a beautiful specimen of Jakobsen in decline. Any idea what’s going on and what we can do to reverse it’s trend? I will attempt to load a photo. The needles are dying from the base up. We are in Ketchikan, Alaska, 180″ rain a year, zone 7. It may be in too shady of a location. Other plants in the area are very healthy. Thank you! Come visit!

PS Are there image size limits? Should the picture show up prior to posting?

2 hours later, time to give up on posting a photo – says “waiting for conifer society” and doesn’t upload.

Geord my guess is that the photo is too big or is in the wrong format. If you email it to me (webeditor@conifersociety.org) I’ll post it for you!

Here is Geord’s photo. Anyone have any ideas? Geord is apparently snake-bit on this photo; it is right side up on my computer but it refuses to post right side up on this site. He would welcome any advice.

Hi Geord,

I agree that your plant definitely looks to be in decline. If this were my tree, the very first thing I’d do is get rid of all of that dead clutter. It’s not going to regrow and it’s a magnet for fungus, especially given your climate. That will get some air circulation going around the plant’s inside.

Next I would check the roots. With your hands, dig down some around the plant’s base. Did you plant it too deeply? Do you have a flare root pressing against the trunk? Girdling roots are actually the leading cause of premature demise in dwarf conifers.

So many possibilities … it’s so hard to diagnose a plant problem from far away using a sideways picture. I wish you luck in figuring it out. I have personally found ‘Jakobsen’ to be a rather finicky plant, especially for the normally bullet-proof Pinus mugo species.
