Due to the crawling, biting things, I stopped carrying very young plants into the wilds until they are at least 8 to 10 inches tall. Plant a LOT, so losing a few won't hurt too much. I believe I would spread some insecticide around the perimeter, "No-LO', or DE, whatever. I like the idea of throwing out seeds in Dec, just for kicks.
A month ago, I collected seeds from a heat-stressed Female. I noticed this morning that a seed had fallen in the soil & has sprouted. The Mother is only about 2 months old. !!!!!!
