Brown crispy leaves on aRonia melanocarpus
I have enjoyed this shrub for six years problem free. Beginning about 3 to 4 weeks ago I noticed brown crispy leaves at the base of the shrub it quickly continued up to the entire shrub. During the heat spell we did water well. Is this heat/drought damage? Could it be overspray from a weed treatment?

Mosquito Trapping
I have tried several commercial mosquito trapping devices only to find that they all capture far too many moths and other benign/beneficial species. Is there research information available on how to keep essential food web species out of traps? Hal Davis. ISU Ex. MG (retired)

What kind of plants are good for this kind of soil seen below?
Good afternoon everybody, I recently got results from the lab regarding soil and plant tests with some surprising results. Instead of being low in nutrients, the garden is quite high. I’m curious if anybody knows what kind of native plants would be good for the soil as described in the attached analysis sheets.
