Plastic Cover for Weed Prevention
A friend recently suggested that we cover our garden beds with clear plastic while the weather is cold here in south central PA. He said the weeds would sprout, and that we should then remove the plastic covers and the weeds would then freeze and die. Then we should stir the soil and repeat the process.
I have heard of using plastic covers to warm the soil and thus being able to plant earlier than normal, but have not heard of doing this to kill weeds. Would certainly appreciate your insights as to whether this seems like something to do.
Many thanks for any responses.
