If you are trying to protect a vegetable garden or large plants from freezing cold or frost, you can make a homemade cold frame. For small plants, it’s easier to make individual greenhouses to keep plants warm and prevent frost damage to their foliage. If you can’t bring a plant to a greenhouse, bring the greenhouse to the plant to keep it warm during a freeze. You can make homemade greenhouses to protect plants from cold using an item that’s found in virtually every house — soda water and milk bottles.
Empty plastic bottle for each plant that needs to be protected from frost or freezing cold temperatures. Large 2-liter soda, water or milk bottles can be used for larger plants, while smaller 20-oz. soda bottles can be used to cover small plants.
* Remove the caps and labels from the soda bottles.
* Rinse the bottles in a sink of water to eliminate soda residue.
* Carefully cut off the tapered {bottom} portion of the bottle using a utility knife or scissors.
* Place the bottle over the plant and sink the edges into the soil, use mulch around the base of your mini-green house protect the plants from the cold and to secure the bottle in place protecting your plant. During the day, sunlight will heat the greenhouse and the bottle will retain the heat, keeping the plant warm during cold nights.

Thank you! I have seedlings in my window sill that really need to go into the ground. They’re lookin’ a bit pale. Can’t wait to try giving them their own personal green houses.
