Answer 2

$\huge \boxed{ \boxed{ \bold{Answer}}}$

Killing weeds with plastic will have different results depending on the color of the material. Clear plastic raises the temperature of the soil. This can kill weed seeds and roots as well as soil pathogens and fungi. It also allows light through the plastic, which can allow heat-tolerant or hardy weeds to survive. Clear plastic is most effective during the hottest summer months.
