sowing seeds over dead grass - will this work

16 years ago

I cleaned out my seed box and have a quart bag almost completely full of old seeds that may or may not be any good. I don't want to invest a lot of time in the seeds but don't want to toss them in the trash either. There are lots of zinnias and cosmos and many other things, both annuals and perennials. Some are several years old.

I am thinking about spraying the back corner of my yard with Round-Up and direct sowing them there. I don't want to till but was thinking about spreading a thin layer of top soil and compost first so the seeds will have a little loose soil to germinate in and then using the stand-back-and-throw method. lol There are lots of seeds so even if I have low germination, I should get a few flowers I hope.

It's sort of a very abbreviated lasagna method. lol Do I need to cover the seeds with a thin layer of soil? Am I wasting my time?
