Black plastic mulch is great for cut flower growers! This time saving plastic mulch has a perforated 2.5" diameter hole every 6". You can easily remove or leave the holes in place to plant in varying 6" increments. Great for cut flower growers or for high density crops like lettuce and greens. No more cutting holes only to have them run together. The perforated holes allow for a much cleaner look and better weed blocking and moisture control. The black plastic mulch is smooth 1.5 mm and measures 4' x 600'.
