Fortunately, most varieties of daffodils are quite hardy and will tolerate a certain amount of frost and freezing. Snow is better with frost because it acts as an insulator. If the temperature is going to drop much below 20 degrees, you could add a mulch of dry leaves. If you’re concerned that you have a daffodil variety that is more frost-sensitive, you could always cover them with a small tent made of stakes and sheet plastic. That said, don’t keep the plastic cover over the flowers when the Sun comes out or they could fry!
