A nearby neighbor decided that he would do this last year.
It looks very much like he sprayed the lawn with herbicide - 2 large trees began to die! I'd be very surprised if either of them make it back this year.
One half of the front yard was not watered and, I believe, has nothing but dead grass on it. The other half, he planted (and
@seedcorn will be interested to know) only to kale. I've seen him out several times this winter harvesting leaves. I don't know what he has done in his backyard. His next door neighbor had a solid board fence set up last year, making it difficult for passersby to snoop
