How do I keep grass from coming up in my flower bed?

The plastic is a fair solution. I like to use landscape fabric and about 2" to 3" inches of mulch on top. You can keep the plastic but add the mulch, It'll choke out any weeds.

Pull the weeds up by hand, then lay down some thick layers of newspaper, wet it well, then mulch over it. I did this in my front flower bed and it really works.

Ortho Grass B Gone. Read the label.

MULCH!

Mulch. Start first by getting as much of the grass pulled up by the roots as you can. Then start with about 4 layers of news paper and soak it thoroughly. Then put about 2 inches of fine bark chip mulch down and on top of that put another 2 inches of medium bark chip mulch down on top of that.

Please do NOT add salt to the soil. It destroys the soil permanently and kills ALL vegetation indiscriminately. Once you've done that, then then only way to remedy it is to remove the dead soil to a depth of about 18 to 24 inches and bring in new topsoil and it's hugely expensive.

Thank you,I’ll try that

Hi Debbie, Mulch will not stop the grass, it simply decays down into great fertilizer and a perfect place for the grass and weed seeds to nestle down and start growing on top of the plastic or landscape fabric. By the way, don't ever use plastic, it does not let the water go through and is not healthy for the plants. I learned the hard way about getting rid of grass, etc., with lots of back breaking cleaning out of my flower beds. Now, I clean our an area to start a new flower bed, work the mulch and amenities into the soil, put landscape fabric over the entire area {making sure the right side is up so the water can go down through it but nothing can come up through it, cut Xs where I want the plants to go, plant all the plants making sure the openings are closed around the stems of the plants, then put only rocks on top of the landscape fabric. Water area and watch the plants grow and the area stay grass and weed free!

I always pulled what I could get by the roots,then put a layer of brown bags from grocery store, then put the mulch on top, it's always worked best for me,😉Lil' secret to keep animals out of your flower beds "pine cones" they don't like the feeling on their feet😃works great!Good Luck!

Good idea, thank you

I pull the weeds and use a small garden spade to get out the ones with tough roots. I think the trick is to not have too much uncovered space. I use a ground cover that's not too invasive. Do not use vines. Check internet for ones suitable to your area. You may still have weeds, but they are manageable. Good luck.

Well, some farmers would say strips of newspaper, in thick layers, soak with water and lay pea gravel heavily to prevent sun exposure. Around the perimeter and add in a mix of diatomaceous earth and you made yourself a weed and slug barrier.
