For those who encourage (or tolerate) purslane, what do you do at the
end of the season? Specifically, turn it under, or pull it? (Or
anything else, for that matter.)

My understanding is that it propagates from cuttings, which makes
turning it under a little concerning. But, it's rather dense, which
makes me wonder if I'd be depleting the soil to just yank it out.

Thanks,
