Where do I start? I want to save as many of the perennials as I can, but the perennials are growing in the brome grass. My thought was to start potting up what I could in early spring as it comes up, and when the flowers are out of the bed, repeatedly spray the whole thing with roundup, till and add amendments, and keep spraying. Is there an easier way? Rather than potting, should I temporarily transplant the flowers to the vegetable garden, and then move them back when the bed is clean? How early can I start transplanting or potting? Will I be able to move the flowers back this year, or will it take an entire year to clean this up? Would it help to also do an application of preen? Button weeds are easy to pull, but I don't know where to start with the brome grass.

Thanks so much in advance for your help. Once the bed is planted, I'll be sure to put down a weed barrier and mulch so it doesn't happen again. I'm not a novice gardener, but I'm not a pro either.

Any and all advice would be wonderful. I plan on mulching

Grass all through perennials is either dealt with by digging everything up, washing the soil off and separating out the grass by hand, or spraying the whole mess with herbicide and starting over.

Or digging it all out and dumping it down a hole.

I would remove the desirable plants as you said, then smother the whole bed under cardboard covered with mulch. Then replant this fall or next spring. I would probably wait until late next spring, after the time when most of the annual weed seed sprout.

I wouldn't use it, but keep in mind if you decide to use roundup, it only works on active growth, there is no need to use enough that it soaks the soil. And the hotter it is, the better it works.
