Get off my Ash … update #6

The ash tree in front of my home has been declining rapidly. A few of the top limbs are now bare. The stress sprouts are re-growing. I had pruned them a couple weeks ago to remove them.

Today I checked for “D” holes to see if the female adult ash borer had left yet and I found quite a few such holes around the trunk.

Now based on what I’ve read, the larvae, from the female’s eggs, will begin to make their tunnels as they feed under the bark.

Get off my Ash … update #5

Well, it’s not looking good for more ash trees on my street. There are about 4 more that are in severe decline. The tops are virtually bare with extensive sprouting along the trunk … indications that the ash borer larvae have stopped the flow of nutrients up the trunk.

Surprisingly, the trees on the opposite side of the street still appear OK, although they likely have been infected. Perhaps, their infection is not yet as major.

As I said in a prior update, the city installed systemic insecticide plugs this Spring to help curtail further larvae destruction until a better treatment can be found. The ash tree in front of my home had the trunk sprouts until I cut them off a couple weeks ago. So far the top of the tree still has leaves but they’re not as large or as full as in past years. Perhaps it’s been a benefit that there has been lots of rain, so at least the trees aren’t further stressed from lack of water.

Thank goodness the trees in our yards are now rather large so we won’t be “bare” when the city cuts down the street trees.

Get Off my Ash … update #4

When I came home today, I noticed a yellow card hanging on my door. It was from the Delaware City Grounds & Facilities Dept. They were notifying us that our street trees – all ash trees – had been treated with a systemic insecticide to control the Emerald Green Ash borer.

The systemic insecticide they used is AC14 Acecap97. They went on to say that implants had been placed in the trunk. The treatment lasts for one year and will be repeated in subsequent years. The treatment period is April and May.

The cost of the treatment is being paid for by the City and is 5% of the cost to remove and replace the trees. They’re hoping that if they do this and keep the trees healthy for a few years, it may bide some time while hoping that a new/better treatment will be developed to prevent the spread of the borer.

They’re going to monitor our trees this summer and if they feel that any are too infested, they may decide to remove the tree. So the saga continues.

Little green borer … get off my ASH

Get off my ASH … a sad update

City workers cut down the infected tree

EDITED: I’ve noticed that there are some twig sprouts along the trunk of the tree in front of my home which is a bad sign. The leaf canopy isn’t as thick and vibrant as in the past, so it appears my street tree is infected. I sure hope the insecticide works and that the City doesn’t decide it needs to be removed.

Get off my Ash … a sad update

Copyrighted diseased ash treeIn early June, I wrote about the potential for the Emerald Ash Borer to destroy all the trees along my street – which are ALL Ash trees.

At the time I wrote the article, one of the trees along the street was ‘suspect’. But this lone tree has always deteriorated in the July/August period. For the past 4 years, its leaves turn brown and drop. By the end of August, it was mostly leafless. Since it seemed to be a different variety of ash, I attributed it to some disease.

Well, this year it didn’t leaf out in the spring and by May, it was sprouting an abundance of leaves along the trunk. Copyrighted ash borer larvae trailsThis is usually a sign that a tree is in the last throes of life … or death as in this case.

Yesterday I noticed that some of the bark had been pulled away from the trunk. Sure enough, the tunnels made by the larva were visible. I wondered if this check had been made by fellow residents, or if indeed the city Parks & Rec folks had done it.

This is just so sad. Our trees have been growing for 12 years, and our street trees have begun to form a canopy over the street. I suppose it won’t be long until I come home some day to find all the trees gone. Then we’ll have to start all over with new little saplings planted by the city.

To learn more about the Emerald Ash Borer, the Department of Natural Resources is a good web site for complete information.

Little green borer … get off my ASH!

Copyrighted ash street treesThe original developer of my neighborhood stipulated that the builders had to plant a certain number of street trees per every foot of frontage of the home’s lot. Street trees are those that are planted between the sidewalk and the street. Generally, that little piece of land belongs to the city, including the trees.

The trees that were planted on my street are all ASH trees, and they’re now about 12 years old and as you can see in the photo, are looking very nice. Ash trees are known to be a great shade tree, so many have been planted in people’s yards as well.

As we’re all too aware, there’s a tiny green insect, called the Emerald Ash Borer, that has destroyed thousands of trees in Michigan and in the past 3 years has moved into Ohio.

Yes, it’s that darn “state up north” again! GO BUCKS!

Two years ago, an infected tree was found within a mile of my street. At that time, Ohio had a policy to cut down ALL ash trees within a half mile radius of the infected tree. So the State cut all the ash trees up to the end of our street.

We breathed a sigh of relief but knew we weren’t “out of the woods” yet. (sorry for that pun!)

We’re all so afraid we’re going to lose our beautiful street trees – it’s probably just a matter of time. Each time we see a city Parks & Recreation truck we look out the windows to see if they’re going to tie the dreaded orange plastic ribbon on a tree signifying the tree is destined for destruction.

Did you know that YOU can help my neighbors and me keep our beautiful trees?

If you plan to visit any central Ohio campgrounds, please don’t bring your own firewood! Your firewood might contain the larvae or the borer.

I just know you would feel very bad to know you took away our pretty shade trees!
