I did this last year with a bed that was getting overrun by grass. I did
have some annual reseeding - not as heavy as previous years, but enough to
supply color later this summer. In this case, the reseeding annuals that
seem to be successful in putting down roots through decaying newspaper are
cosmos, shirley poppies, and california poppies. A few lavatera squeaked
through, and one or two others species, but the above seemed the most
determined. I'm very pleased though to have cut down on the weeds - although
I did some additional spraying with grass-b-gone to get the grass that
sprouted between sections of newspaper.

I have some neglected beds that are badly in need of weed control &
mulch. I want to lay down newspaper (working around the plants that
are supposed to be there), then cover with mulch. However, I'm
concerned about the whether the annuals/biennials (we're talking
nigella, foxgloves, & columbines) will reseed. Wiil the seeds
germinate in mulch? And will the newspaper break down enough by next
year for the plants to develop roots? Anybody have any other
suggestions?
