Emerald Ash Borer - Dakota County infestation

eab-adult_d-west800x350.jpg

The infestation in Dakota County including Eagan, Mendota Heights, and Inver Grove Heights is in full-swing for the Emerald Ash Borer. The City of Eagan and surrounding neighbors are planning full-scale removal projects that are expected to take 7 to 10 years to complete.

Signs of the Emerald Ash Borer

Exit holes and some wood pecker damage

Usually the most obvious way to identfiy Emerald Ash Borer (EAB) damage is to inspect your tree for woodpecker damage. Woodpeckers will pick away at bark on the tree to eat insects and larvae and most trees in the area are showing these signs already.

The City of Eagan has released special wasps in Blackhawk Park in the June of 2019 to help slow down the spread in the park and help manage trees that they cannot easily remove. There is some hope that they will move on to nearby neighborhoods, however most trees already have damage and will need to be removed.

It is important to note that you should not transport any wood from Ash tree removal on your property outside of the county or state as it is possible to easily spread the insects or their larvae and create new infestations.

What to do?

If you have Ash trees on your property with or without signs, you will almost certainly have to remove them. Trees planted in the boulevards will be handled by the cities and their contractors, but the rest will be your responsibility.

Planning ahead

After you have decided to remove infected or soon to be infected Ash trees on your property, most often you will want to replace them with a similar decidious tree. There are many great choices, but if you are planting multiple trees, please consider plant selection diversification so when we are faced with the next insect or disease crisis, the impact will be less dramatic.

Choose a hardy variety that is pest-resistant and will survive in our Zone 4 climate. Visit a local nursery and ask them for their advice, many local growers have had trees in their fields for 10 to 20 years or more and can tell you what has survived, thrived, or failed.

The extension office at the University of Minnesota also has a lot of information on hardy trees that are recommended for your area.

2018 - Spring updates

springpic2.jpg

Spring has arrived..

After a historic April 2018 blizzard, winter is finally behind us. We have put away all of our plows and snow removal equipment and are prepared for short Spring and Summer months ahead of us.

While it is still probably too early to begin dethatching or lawn aeration, now is a perfect time to remove any leaves that still might remain in your yard. Leaf removal in the Fall and the Spring is especially important to help protect our trees from Athracnose, a fungal leaf spot that attacks Ash and other varieties of shade and ornamental trees in Minnesota.

If you have any questions or concerns, or would like to speak with a turf care expert in your area, please call us at 612-384-2517 or e-mail sales@southmetrolawncare.com.

10 Tips to get your lawn ready for Spring

Make repairs to sprinkler heads and test irrigation system.

Prune broken, damaged, or diseased limbs off trees

Wait until the end of May or early June to apply fertilizer

Get a soil sample and a fertilizer plan

Look for signs of snow mold damage. Rake up area, top dress and seed

Look for signs of voles - these usually indicate a grub problem

Crabgrass pre-emergent control should be applied when soil temperatures reach 55F, typically in early May. This year we will most likely need to do this a little earlier, but not before the first mowing.

Re-seed bare spots or top dress entire lawn and over-seed

Aerate your lawn

Sharpen the blades on your lawn mower.

From @urbanturfmn: "Interesting to see spring effects from fall lawn care. I believe the lawn on right had more fall nitrogen #snowmold "

UMN asking public for help with Japanese Beetles

The University of Minnesota is interested in learning about Japanese Beetle infestations or occurrences outside of the known heavily infested areas already known to researchers. If you suspect that the Japanese Beetle may be in an area not known to be infested, please contact the MDA at arrest.the.pest@state.mn.us 

More information on the biology and entomology of the beetle can be found here.
