Anytime there is a weather forecast for a hard freeze, we can cover our plants to provide some protection. If the sky is overcast and rainy there is less chance of cold weather than if it is clear. If you have seedling plants that are just emerging or half-hardy transplants, you may want to consider covering them overnight. Place covers such as blankets, boxes or plastic (not touching the plants if possible) over the area late in the day. Windy conditions may blow covers off so anchor them down thoroughly. Dont be concerned with seedlings that have not emerged or potatoes underground. They will be fine.
