Replacing/Killing St. Augustine Lawn
My St. Augustine has been a disaster. It has never looked great--and I've had to replace various bits on and off every few years. The backyard is now pretty much gone...way too many weeds...too sparse...etc. I thought I would try and kill off most of it...and make some nice large beds that I could plant with crape myrtle or something else.
If I put roundup on the lawn where I want to make the large beds...will this harm the crape myrtle? Is it better to just lay down landscape cloth, cardboard, ????
Ideally, I'd like to do most of this in a weekend, if possible.
Thanks for any and all advice.
