It works well when the temperatures are hot enough. Here in the frozen
north my experience with clear plastic left over the winter on the soil is
that in the spring it only gives the weeds and grasses a good head start! :-D
They are more frost tender though so once they are growing well taking
the plastic off very often allows frost to kill the early growth.
