Hi - we had a 13 large - beautiful arborvitaes installed by a reputable Landscape company last September (4) and this May (9) - they all have done beautifully until one week ago — when I noticed one of them on the side looked odd so I walked over to the row of them and walked behind the row and five of them appeared completely dried out and dead on the Northside and healthy and vibrant on the south side. They are planted in our garden in a shaded area so the sun is not hitting them hard. When I touched the bush the needles all fell off - the branches completely dried out— they also have a strange color to them on the north side — almost like they have been spray painted. There is no yellow or brown branches. And the all began dying off like this within days. This all began last week. What is very curious is that our neighbor had just had their back yard and trees sprayed for mosquitos and that day we had a very strong north wind - so strong that my husband came into the house because the fog from the spray was so dense. The trees starting dying off a week after this spray. I have called the Mosquito company and they came out yesterday and said - their spray would not kill trees/shrubs. They do have something they use on the ground that would kill Trees/shrubs but the representative said that should not have been in their tanks. I had the Nature Designs landscape company come out — specifically the owners and after two inspections they told me it is not a bug/mite that this appears to be an environmental spray or toxin spray. Now I feel stuck between no one wanting to clearly identify what the problem is as the bushes are still in warranty by the landscape company - however this was an expensive project, and I assume they do not want the liability. The Mosquito spray company does not want the liability either. I have kept the bushes watered and the ones that were installed last September came through the winter just fine. I am hoping someone can help me determine what is/has killed my beautiful shrubs.. they seem to be loosing more needles and drying out daily — on one side only. Our home is in Maple Grove on a Natural Wetland and the shrubs are inside our fenced yard.
