Is there anyway to get rid of Crab Grass in my Flower Garden?
Crabgrass is an annual that will die come the first frosts this fall but it will return next spring from its seeds. RoundUp or hot water may kill the vegetation this season but, again, it will be back next spring. Your problem is the mass quantity of seeds produced by this plant. Use a pre-emergent next spring to control seed germination %26amp; you will not have this problem. Apply a pre-emergent around the time that the forsythia bushes start blooming and water the product in well. Preen Garden Weed Preventer is a typical pre-emergence labeled for the control of crabgrass in an ornamental garden available at most home %26amp; garden centers. Read %26amp; follow all label instructions when purchasing or applying a pesticide.





Also be careful how you water your garden. Frequent, short watering encourages seed germination. It is always best to water deeply and infrequently.

Reply:I think they have a shampoo for that. You should ask your local doctor. In the mean time you should look around and see if you can find a plant poison specifically for crab grass. I think they make things like that. If it's feasible you should take up the bed. You don't have to throw anything, just take it all up, dig down as far as you think the roots of your plants will need to go and place a liner. Then replace all the soil and mulch. Then and crab grass is just a stray seed and can be pulled up as you see it growing. Good luck.
Reply:Your mulch needs to be at least three inches thick. And you may want to go even higher at first. You an use hot water on the crabgrass, also make sure you are pulling up the crabgrass roots and all.
Reply:Spray ROUNDUP, (sold at Wal-Mart) on crabgrass and it will die in a few days and it won't grow back.
Reply:I just did this at my house. I bought roundup regular strength. Use it according to directions. I used a cardboard box to shield my plants. The roundup will kill the weeds but it neutralizes at soil level so it will not harm anything in the soil except what you spray. Mine are dead and flowers fine. Happy gardening.
