Shriveled Leaves on Trees
I'm concerned about some trees in my yard which have shriveled/curled leaves. Here is a shot of my Umbrella Magnolia. I apologize for some blurring in my images. there were taken with my phone. I have recently sprayed some Spectracide lawn weed killer carefully around them, and some Spectracide Weed & Grass killer around them as well. Both times I was very careful to not get overspray.
Also, my sister lives next door to me and I've observed the same thing on her trees as well. Pin Oak, magnolia, maple, .. so I don't think the issue is exclusive to a species or type, nor am I convinced it was the weed killers.
Any ideas as to what's happening? We did as most of you probably know, have a historically bad winter, a late freeze about 3 weeks ago, but I'd say by now the trees should have bounced back (?). We also had a sudden hot spell, close to 90 degrees, but still I wouldn't attribute it to that.
Thanks in advance!!
