| Blue Mulch, 4 ft x 50 ft |
| _____________________________________________________________ |
| Ten years of field tests at Pennsylvania State University prove it: Cucumbers, melons and squash love the color blue. This amazing blue plastic mulch reflects the specific wavelength of blue light that stimulates plant tissues, producing consistently bigger yields and firmer, sweeter fruit. University tested! Maintains soil warmth during cold snaps. Suppresses weeds. Conserves moisture. Triggers positive light response in plant leaves, even by moonlight! |
