Even though my sprinklers have been broken for three years I still have a yard full of bright healthy St. Augustine grass. It is the living green monster of a carpet that I can't seem to get rid of. All my neighbor's water their yards in excess, even during the rainy season. Why? We do not need to water in South Florida in the summer because it rains almost every afternoon. If your sprinklers are set to automatically water, please consider turning them off. Your garden will live, you will conserve water and you won't have to cut your grass as often.
My overall garden plan is to return it back to a native landscape with a few fruit trees and vegetables mixed in. Sounds easy enough, only it isn't that easy. Grass is my number one problem. After backbreaking hours of digging up my grass up, it simply yawned and grew back.
If you are like me, you shop online. The only problem with shopping online is that it comes with cardboard boxes. My two problems: too much grass and too many boxes.
I decided to try putting the cardboard boxes (the blank ones without printed coated paper) over my grass and put a layer of mulch on top to keep it in place. IT WORKED!! Not right away of course, but about the time the box disintegrated the grass underneath was gone too. The photo above shows some of my grassy areas where I removed the grass with cardboard boxes and planted Beach Sunflowers from cuttings and seeds.
If you live in South Florida, now is the time to save your cardboard and start preparing your soil for planting vegetables. If you put the cardboard down now it should be ready to plant by October right when it starts to cool down.
