I have a raised bed garden used to grow vegetables. 8x8 divided into three big "boxes", right now I am weaning out of my spring/summer "harvest", i planted cucumbers, eggplant, grean beens, tomatoes, grapes, had a great cucumber, and green bean harvest, few tomatoes, and my eggplants are starting to grow now , i am in the process of moving my beds, to a different location in my backyard. I realized that in the current location, my garden was getting COOKED!! I live in TX it been over 100 for the past 3 weeks, so I plan on moving the beds to a part of my yard that gets more shade, sooner in the day. ok so quick background, I have three chickens that free range in my backyard, and yes they get "garden" privileges, they also eat alot of what I "harvest" so if you have read this far, my question is this, HOW DO I KEEP MY YARD GRASS FROM CREEPING IN AND STARTING TO ROOT IN MY RAISED BEDS!!! im not yelling, i just wanted the question to be clear, right now my beds are full of grass, creeping in, I am sure the grass is just trying to get to the water/better soil. SO is there something I can do to try and prevent or even kill the grass to stop it from creeping into my beds when i move them. whatever it is would have to be organic, and natural, cause of my ladies just an fyi, I did put down a few layers of "weed" proofing material, and it extends under and about 2 feet around the sides of the beds, lol my grass is just laughing at it right now!!!, the grass is a mix of St. Augustine, and Bermuda, and its really the bermuda grass that just does not want to die!!!! any and all suggestions appreciated, thank you for taking the time to read and reply!!!
