PlantFiles is getting a new look! Just in time for spring, we're rolling out a new look for the best online plants database. It will also work with your smart phones and mobile devices, so now you can take it with you on garden center visits or botanical garden tours. Questions or comments? Please post them here.
Drat, I was hoping that the bug would stay away longer, we have several green ash trees around home and lots in town. I still remember Dutch elm disease, as the trees lining the road to the farm just kept dying off,,so sad.
I talked with my DSIL this past weekend who lives in Northern Illinois. She has 13 ash trees on her property and the ash borer is closing in fast on them. (10 miles away) They talked with someone who could come in to treat them. It would cost her $5,000.00 per year to treat! Ouch! She is going to let things take their course.
staceysmom - Where does your DSIL live (or nearby towns)? We have 6 Ash (2 are mature large ones) on our lot and 1 maple and many more on our lot next to this one. I've heard they're in the northern suburbs here, Chicago, and now the far west suburbs so they're spreading. I am just hoping and praying they avoid our area but I'm thinking it's almost inevitable. My poor shade gardens will then be full sun :(( Anything I buy now will have to tolerate sun I guess. On the upside, they've staved off the Asian Longhorn beetle around here. I certainly wish you all luck in Wisconsin that they can keep them at bay! I was talking to someone on the clematis forum. She says they have them there too and she's got many ash trees on her property too. They've decided on new trees to plant should theirs succumb plus keep many as totems with climbing vines.
Yes, that sure does sound like a lot of money. I was telling her that I had read in the paper about the scam artists out there and like JuliaJayne said, to call the county extension. I'm not sure if it is the 2 year version. She said it was per year?
Medinac, she lives in Downers Grove. She was also concerned about her shade gardens. She loves and collects hosta. Good luck with your 6 trees. Oh, how I would hate to lose trees like that. Yes, you can plant other trees to replace them, but it takes so long for them to mature! But, it may come to that... what 'cha gonna do?! I have heard that one of the main ways it is being transported is by firewood. People are cutting up their infected ash trees and using them as firewood and transporting it to other areas.
Here is a link to the IL Dept. of Ag's page on EAB. At the bottom of the page, it says that there is treatment available but that there's no guarantee the trees will not become infested. (Chemical to treat is emamectin benzoate).
Hope this helps. If you have ash trees that are providing shade on your property you may want to consider a proactive replacement program. Otherwise you can let nature take its course. But be aware, should your ash trees become infected you'll likely be required to remove them at your own cost.
chatnoir - Thanks very much for the link. It was interesting and informative. It doesn't seem worth the money and trouble to treat them since the IL DAG can order them removed anyway. That is a boatload of money to treat them without a guarantee of it working! I suppose we can just wait and see and start planning for replacements. The Morton Arboretum has a good site for tree selection. I found it before when we were thinking of underplanting our Ash off the patio when our tree guy hacked off our major shade branch when trimming our tree. I was mad when that happened so I can't even imagine having total, complete full sun. And I was going to find some nice hostas - I don't think any of them can handle full sun.
Yeah. Many municipalities are taking or considering that approach. It's a financial decision. They can calculate fairly accurately how much per tree it costs to remove them. But the wildcard of having the tree succumb to the borer and then fall on a car or a tree is a risky budgetary move. And since it's tax dollars involved they figure it's better to spend less of them than more, I think. Course I wish that same logic was applied consistently! LOL!
