Dill is supposed to be a good companion for cruciferous plants. I had trouble with asparagus beetles last year so have planted some dill among them. My herb garden is near the asparagus bed.
The asparagus is not showing yet.
I had some two year old onion seed I had saved from Stuttgarter onions I had planted and figured, what the heck, and sowed them and got more onions than I know what to do with. I was impressed at how many were viable.
Also, I found black swallowtail caterpillars on the dill. It was good to see them.
