A dozen dead Hydrangeas?!
I've had over a dozen beautifully blooming healthy hydrangeas for the past 3 years and this year every one but ONE looks like the picture attached. My green thumbed father is adamant that our lawn service poisoned them via overspray, and the fact that every one EXCEPT the single one that came back normally are positioned within 2-3 feet of my lawn edge supports that hypothesis, but I would like some support before blaming them outright. What kind of lawn-care chemical could have done this?? I'm sure they will say that they have been treating my lawn for years and it never happened before... so is there any other rational explanation? There is a bit of new growth in each so will these eventually come back to full life? I would really appreciate any input/ advice!!
