Winter is upon us in the great southwest USA! The days are chilly and gray and sometimes filled with the occasional rain, sleet, and snow. Recent stormy weather in Arizona has shown just that. 

Additionally, the nighttime temperatures have dipped into the freezing zone. Temperatures that dip down into the 30s can wreak havoc over time on growing plants, flowers, and vegetables that do not stand up well in cold temperatures. 

That’s why it becomes important to winterize your vertical wall garden during these weeks of winter temperatures. Seasonal cold spells can damage some tissues of your plants and vegetable tissues if not covered during freezing temperatures. Without some protection for your plants and vegetables, these fragile plants may not achieve their full growth by spring.

To help ensure that the plants and vegetables in your vertical garden stay in growth mode, we suggest the following tips to ensure the seeds that you planted are able to mature into bright, prosperous plants and vegetables. 

  • Use layers of mulch and hay to help insulate the soil in your vertical garden. By covering the soil in your vertical garden, you can help keep in the heat and moisture to protect the plant’s root systems. 
  • Invest in some frost cloth to cover your vertical garden at night. It’s important that the covers be breathable and water permeable. These covers will help to protect against freezing temperatures and help stabilize the plants and vegetables during these early growth stages. Not all plants can withstand the dangers of frost and freezing temperatures. 
  • Construct a mini frost cloth covering the area around individual plants. If your vertical garden planter holds vegetables in one of the tiers, for example, you can make a wall of frost cloth around the vegetable. Simply insert 3-4 wooden sticks into the soil around your plant, being cautious not to damage the agricultural food-grade liner, and wrap the frost cloth around the sticks and seal with a clip. You can add hay or mulch between the frost cloth side and the plant. Your plants will enjoy the additional insulating layer of warmth. 

Winter usually doesn’t last long in Arizona, but some winter seasons can last longer and be colder than others. It’s best to be prepared when the cold arrives.
