If your gardening work occasionally calls for a greenhouse, but you can't justify the expense of a permanent structure, you can build a temporary greenhouse as the need arises. Simple greenhouses can be made in a matter of minutes with a few materials. An added bonus of a temporary greenhouse is that you can move it to the location of the plants, not the other way around.
Things You'll Need
- Wooden stakes
- Sledge hammer
- Roll of clear plastic (.4 mm thickness)
- Duct tape
- Razor knife
- Heavy duty staple gun and staples
Mark a perimeter for your greenhouse on the ground. This can be as simple as using a stake to draw a line in the soil around the plants that need to be inside your temporary greenhouse.
Use the sledgehammer to drive stakes into the ground every 3 to 4 feet along the marked perimeter.
Lay the plastic over the stakes, forming a flat roof over the plants. For those areas that are wider than the width of the plastic, lay out two or more sheets flat on the ground, overlapping the edges by about 2 inches. Seal the sheets together using duct tape along the length of the edges.
Staple the plastic to the stakes to secure it in place, leaving a couple of spots unattached so that you can lift the plastic on hot days and allow circulation.
Use the razor knife to cut small, square holes in the top of the plastic, spaced every 2 to 3 feet. These holes will serve as vents.
