Went to ABS and now need Deadwood help!!
At a raffle in April we won a San Jose juniper styled by Marco Invernizzi. We are in love with the tree. Over the weekend we had a great time at the ABS conference. Unfortunatly when we came back there were little piles of sawdust on the tree.
We believe the damage is from bark beetles. The tree was sprayed with a weak solution of Sevin, mostly on the bark. Online I found info. saying that bark beetles attack trees with damage and to remove the damaged parts. The problem is that the whole tree is "damaged" with the extensive deadwood. Any ideas, similar experiences?? |

Coincidentally I was researching yesterday the many pines I've seen lately that are rust colored and quite dead. It seems that Pine Wilt is a possibility. Evidently stressed trees, mostly ones affected by drought, are suceptible to certain beetles that bore into the bark. If I understood the article correctly, a "blue fungus" enters the tree somehow through the beetle-bored holes and spreads, then a specific nematode that feeds on the blue fungus comes into the picture and finishes off the tree.
I dont know if this could be evergreen-in-general, or just a similar symptom. Also, according to the article this seems to be most prevalent in the midwest US, although here on the east coast there are an unsettling number of dead pines, even mixed in with healthy looking ones. |
