Well it's come time to give Basil a decent burial.
The poor plant hasn't done well since the weather turned poorly. His stalks are black and leaves yellowed and mottled. There's no way he'll survive the winter.
I do have a small cutting which I've planted. I'm going to see if, by keeping it mostly indoors with occasional forays outside when the sun is shining, I can keep it going over the winter. But it's more a growing experiment than anything else.
As for big Basil, he's into the compost bin until he returns in a couple of years as rich, nutritious, natural black potting soil.
