Old Plastic Sheeting

Question

I just moved into a place that was vacant for 20-25 years. We found old, disintegrated black plastic sheeting in the garden area under the grass and weeds. It is impossible to pick up as it just falls apart. Will it be harmful to my flowers/herbs or vegetables if it is tilled into the soil. It had been there over 20 years.

Answer 1

No, it will not harm the plants or make them unsafe to eat.
