Yes, Donald, I have fennel growing in two locations. When one plant gets eaten down to the nub, I break off the stem (with caterpillar) and truck it across the yard to the new site. The cats don't seem to mind the move. Hopefully the used-up fennel will recover and put on new growth....
Melanie, those are really depressing statistics on the swallowtails. I wish I had the dedication to bring them indoors to raise them, but I'm just not up to cleaning critter keepers anymore.
Thanks for all you do.
