Wow, W. George. I don't expect to live another 18 years, so that
certainly answers my question.
I put them in plastic pots for the present emergency, which you can cut
with a knife or scissors to get them out and into a bigger pot.
Someone told me to buy Sluggo for snails. Our supply store didn't
have it, but I got something similar that appears to be working. I won't
put poison in the back yard where the dogs play, but I don't mind in the front
yard that much. If things that don't live here are reveling in flower
beds, on their heads be it.
But I don't want to kill the earthworms, which appear to be abundant every
time I stick a trowel in the soil.
