What does “cover them on frosty nights” mean?
A- If it seems especially cold at bedtime, or if the weather report forecasts widespread frost, the plants need a “blanket” to keep from getting damaged by cold. If you live in a cold area, such as the mountains or in a low spot (cold air sinks), even “scattered frosts” may apply to you. Appropriate coverings include row cover (Reemay), burlap, or old sheets. Heavier materials like actual blankets need to be kept off the young plants by stakes or some other system to prevent crushing them. Plastic is not as good a choice.
