The Q&A Archives: Johnson Grass

Question: I have clumps of Johnson grass in my Bermuda yard. How do I remove them?

Answer: I would dig them while they are small and manageable. Johnson grass is tough as nails and hard to eradicate! A single plant can produce over 5,000 seeds that can lay dormant for up to 20 years. Ugh! If you are dealing with a small amount, try digging it out, roots and all. Be careful, though, because the rhizomes usually break off easily and are left in the ground to spread. If you yard is heavily infested, digging them out is probably not goint to be easy. No good management solutions exist for this type of grass short of tilling everything up and starting over. Spot treatment might work. Any vegetation killer you use can harm your bermuda, though so apply with caution. Wish I had more solutions to share. Best wishes with your turf!
