I feel for you. We have bermuda grass..that stuff is horrible and my critters don't like it. I also have hip and knee issues. I have an acre garden that I plant and work every year. My husband noticed I was having issues hoeing the garden. He took and sharpened my hoe and bent the neck so it got more of a bite. I love it. Eats right through most of the weeds. Now for that obnoxious grass.....I have a dandelion puller (not for my dandelions though). You step on it and it is spring loaded, pulls up the roots. Every time I see the green starting back up, I hit it again. We are in Central Oklahoma. I have found that a shade cloth is an absolute necessity if I want anything to do well. I have a line of bright green in my grass.....it is the area of yard that gets evening shade. I had to relearn how to grow a garden. I lived in northern Missouri for years. Gardening there was easy. It has been a real learning curve here. During the dry season (seems like most the year
) I put out buckets with drip irrigation as I have to haul my water. I really need a catchment system.
