Thermal Wall for Garden Plants

As colder temperatures set in and winter makes its bitter cold appearance, who says you can’t grow all of those great vegetables you love and keep your outdoor garden going? You can! And it won’t require an elaborate, energy-intensive heating system. You also won’t have to worry about breaking the bank trying to keep up with a high power bill.

This will work especially well if your home is made of brick, stone, or concrete. In the case of those with wooden walls, try using black barrels or tanks of water along the outside of the wall to act as a thermal mass heater. For best results, a wall that faces to the south will get the most sun exposure to heat up throughout the day.

The next trick is trapping the heat, and that involves making a narrow “greenhouse,” using the thermal mass wall as the back. Whether it’s a temporary greenhouse or a permanent one, consider using recycled or repurposed materials, such as reclaimed windows, scrap wood and some clear liner from a construction site. Whatever you use, just make sure it has a good seal so that it holds the heat in during the evening hours.

On tomorrow’s this land of ours, choosing the right plants for outdoor winter growing.
