For best results, use Gardeneer Garden Staples. These staples are easily pushed through the fabric and into the ground by hand. Use a staple wherever the fabric overlaps and place them approximately 2 to 3 feet apart.
Also use staples to hold fabric down around plants and shrubs. The objective is to keep fabric close to the ground and the soil completely covered; the less exposed soil, the better your protection against weeds.
If Gardeneer Garden Staples are not available, simply covering the fabric with a 1" to 2" layer of mulch will usually keep it in place. However, the chance that it will move or lift up over time and leave an uncovered section of soil is substantially increased.
