I wanted to use herbicide on a patch of my yard that

The idea, as I read in various meadow how-tos, is to
rid the ground of weeds and plant the meadow mix so
it will be able to get a head start on weeds in the
spring. Will black plastic sheeting kill the weeds
in time? Or should I wait for the next warm spell
and try spraying again?


Didn't mention a specific product, but some herbicides work within a
temperature range. Black plastic sheeting will kill many plants,
maybe not seeds. If the ground is not soggy or frozen you can
rototill, or hoe off the weed tops every 6-8 weeks.
