How do I kill grass and not kill perennials or ground cover?

Answered

I have a mostly shaded bank that has about 30 small "volunteer" hostas growing, along with some "volunteer" creeping jenny, that all have migrated from another flower bed, I did not plant any of them on this bank. I would like to kill the grass on this bank and turn it into a shaded bed, but there is quite a bit of grass/weeds. Would appreciate information on how to kill grass in flower beds and not harm the plants?

    The only other suggestion is to smother the grass out with heavy black plastic .

    If you intend on making this shaded weedy area into a garden area, you can lay down black plastic but that can take weeks to smother. I would personally dig up the area you'd want to plant in, removing weeds and grass as you go and then add organic soil and plants.

    If you are working around plants you want to save, your alternative is pulling/digging. Lots of work; but worth it in the end. If you are not saving plants, then the plastic above is perfect.

    The plastic was meant to be placed in-between the existing plants.

    Use a blow torch it will kill grass and weeds. I use this to kill crab grass. Once it turns a brighter color it's done. Then add your top soil or mulch. So it won't grow back. Some state park's have a controlled fire. But if you don't use topsoil or mulch all new fresh beautiful soft grass will grow in.

    My cousin has used Preen Garden Weed Preventer Plus Flower Food in her flower beds and has said it has worked safely.

    For any plants where I need to be extra careful, I put the weed killer on a rag. I then can wipe the rag just on the grass/unwanted plant, starting at the base and sliding it to the top. That way I don't get it anywhere but the plant/weed I want to get rid of.

    There is grass killer in spray containers. We use it to kill the grass that shoots up in our Myrtle and Pachysandra beds. It doesn't harm anything but grass. I think it only comes in smaller containers. I don't know what you would do for a lot of grass.

    Lay cardboard or newspaper on the grass for several weeks. Lots of articles on the web, including Pinterest.
