Garden Plot Plastic Wrapped

We experimented with plastic wrapping our garden plot early in February after rototilling.
The plan was to have our garden plot "baked" for 10-12 weeks under the black plastic to decrease the viability of the weed seeds and roots in the soil.
So today the plastic will come off and our son and his girlfriend are coming over to help with the rototilling and for an afternoon of socially distanced visiting.
