Herbs and Summer Vegetables

Many herbs and summer vegetables won’t tolerate much frost.

It’s much more pleasant to do the cutting before a freeze turns these plants black and slimy.

It’s estimated that a frost may occur earlier than the given date 30% of the time.

A light freeze is defined as 29F to 32F, which will kill tender plants.

A moderate freeze is 25F to 28F, which is more destructive.

A severe freeze is 24F and below, which will kill most plants in the garden.

Keep an eye on the forecast.

If a light frost is predicted, you still have time to protect plants.

Just drape a row cover over them to help insulate them from the cold.

In a pinch, even a bed sheet draped over the plants will help.
