|Last year my teenage daughter tried to start a flower garden along our driveway. She dug up the existing grass and planted gladiola bulbs. Then she moved out, leaving me to take up where she left off. I tried to plant a few wildflower seeds in the remaining area, but I am having a lot of difficulty with the grass coming back in. This year I tilled the soil and bought a few small perennials to fill in. I have mulched twice, (the first time rain washed a river through my garden) but I still have grass coming up everywhere. I am afraid to use pesticides around the small plants I have growing now. How do I keep the grass from coming back? Also, I am thinking expanding this garden down the rest of the driveway, but it is grass now, and I am afraid of running into the same problem. How do I prevent this in the new area?
