I bought a little plastic greenhouse 5 X 5 and 6 foot tall. We secured it to the ground with tent stakes. We had 40 mile hour winds last weekend. The tent stakes held down for the most part but , it got wind under it and it blew away. I was able to put it back together, a little beat up. I didn't have any plants in it yet. My husband thinks strawbales around it would work, but then we have also seen a few snakes in our yard. Any help would be greatly appeciated.
Ummm, think I would go with trlr house tiedowns, the winds will be back, the ground soaked, you will need something you can drive pretty deep- tposts? Which will let you throw a strap across to help keep the unit earth bound? You can always cover the tposts with plants later in the season? Luck
I have a GH similar to yours. Because I'm tall and didn't want to be bumping my head all the time, I attached it with decking screws on top of 18" wide 18" high raised bed down each side. It's been rock solid in big-time summer thunderstorm winds, although early on the wind blew out a couple of side panels and a roof vent. I've since reinforced things to prevent that..
A lucky decision to put it in that way. At the time, I didn't know about the advantages of raised beds - now everything we have is in a raised bed.
Right now my GH is sitting next to my kids old swing. I have two lines of plastic baling twine tied off to the swing, going up and over the outside of the greenhouse and tied to a 5 inch pine fence post laid on the ground at the base of the other side. There's 60 mile winds coming through this morning. I'll let you know if it's still standing when I get home from work.
