Black plastic #325323

Asked May 26, 2016, 10:01 AM EDT

I mowed down an area of wild raspberry and thistle bushes and placed a large sheet of black plastic to kill them off. Now I have put 4 hills of pumpkins on the plastic. Should I cut the plastic away once the pumpkins start to vine, or will they be okay growing on the plastic? I will put boards under the pumpkins once the develop. Near Duluth.

St. Louis County Minnesota

Expert Response

The vines should  be OK trailing on the plastic.  The following information may be of interest:
