How to Anchor a Greenhouse

Small greenhouses are valuable structures to have in areas that experience colder weather for part of the year. They allow you to extend your growing season by several weeks or months. Greenhouses need to be properly anchored down to the ground to prevent them from blowing over in strong winds. This will prevent damage to not only your greenhouse but also your plants. Anchoring a greenhouse requires a few tools and a little time.

Go to a corner of your greenhouse. Place the drive steel inside the anchor. Strike the drive steel with your hammer to drive it into the ground. Keep hammering until the end of the cable slightly touches the greenhouse base edge.

Grab the drive steel and pull it out of the ground. Insert it into the cable loop and pull the cable out of the soil 2 to 3 inches. Doing this rotates the anchor into a horizontal position, which will lock it into the ground.

Secure the cable wire loop to the greenhouse base. Insert the lag bolt into the driver on the cordless drill. Place the washer over the lag bolt. Screw the lag bolt into the greenhouse base so that the loop in the cable wire is between the washer and the greenhouse base.

Repeat the above steps for the other three corners. Your greenhouse should now be properly secured.
