The cooler temperatures that come with the month of December may call for plants being covered. If the temperature dips to 45 degrees or lower, your plants will need to be protected. You will want to cover your plants before dark to trap warmer air. Blankets, sheets, towels and tarps can be used to cover plants.
Also, do not forget to water your plants! Even though it is not as hot and your plants are dormant, they are not dead during dormancy and still need water. Watering earlier in the day is key to allowing your plant enough daylight to soak in nutrients!
Here are some ideas for your winter garden:
