Answer: Crabgrass is easy to control in both turfgrass and ornamental beds with herbicides that are applied before it germinates (preemergent herbicides) or after it germinates (postemergent herbicides). Read the label to make sure the product can be used around the ornamentals in your landscape. Use a crabgrass killer now, wait a few weeks and then rake out the dead crabgrass. Acclaim will control crabgrass in garden beds without harming most plants but be sure to read the label before purchasing (formulations change and you'll want it to be safe for your plants). Next spring use a corn gluten based pre emergent and the crabgrass seeds will not sprout. Best wishes with your landscape!
