Best weed blocking perennials
I have a big problem with nutgrass (and bermuda grass) in one of my flowerbeds. I know the best control would be to completely rebuild the bed from scratch, but that would take hours and hours of work.
In my opinion my best option (which is very limited as a mostly weekend gardener) would be to plant perennials (or annuals) that would block the weeds seed from germinating in the spring.
Can anyone give me some ideas of attractive, low growing, plants that will live through winter, without dying back, that would serve this purpose? I have a pretty large sunny area to fill in and I live in Dickinson Tx (Galveston County).
I would assume if I wanted to grow annuals I would have to plant them now for them to get mature enough to block the seed germination.
