If you follow me on Facebook, you know that I am always in groups answering questions about AeroGardens or participating in chats about gardening. Sometimes I end up typing the same thing over and over again. I almost did that today adding comments about what I did to strengthen my greenhouse. I finally realized, “Duh… you have a blog lady. Start turning these Facebook posts into blog posts.” So, you will see more gardening content start to show up on the blog. As previously mentioned, last year I realized that I really do enjoy gardening. So, it has become a part of what I do. And, this blog is a reflection of me, right? Don't worry… the tech is not going away! If anything, that will be expanding too. So, this post will be one of many in the gardening realm.
Last May, I purchased a cheap greenhouse on Amazon just to house the few plants that I thought I would have (HA!). I spread out well beyond the greenhouse, but I still used it for a lot of my plants. One thing I learned even before assembling it, was that if you just set up one of these and leave it and expect it to be there after a windy day or a storm… it won't! I have seen a few posts from friends saying that their greenhouse fell over or blew away. So, here are my 5 tips for beefing up your cheap Amazon, Aldi, or Walmart purchased greenhouse from the start so it will last throughout your growing season and beyond.
These polyethylene greenhouses are a popular option because they are very reasonable, great starter greenhouses. However, if you don't do a few things to strengthen your little greenhouse, it will not last long.

How to Strengthen a “Cheap” Greenhouse
Assemble Correctly
This should be obvious, but it's easy to not push all of the poles securely into the connectors or to inadvertently loosen one while moving the greenhouse. So, once you move it into place, just be sure to double-check that all connectors are secure.
Anchor The Greenhouse to the Ground
My greenhouse came with little simple spikes or tent spikes for the purposes of securing the cover to the ground.
These are nowhere near strong enough to hold the greenhouse together during strong winds. If sitting your greenhouse on grass or dirt, instead, pick up some of these heavy-duty landscape staples aka U Stakes.
They are the perfect size to wrap around the poles of the greenhouse. Use a mallet to pound them securely to the ground. I probably used a total of 15 or so all around the bottom.
If you are setting it up over concrete or wood, you should still anchor it. However, I have not done that, so no advice!
Zip Tie the Shelves
Strangely… all of the greenhouses like this don't seem to come with a way to secure the shelves to the poles. They just sit on top. I just knew that I was going to bump one and knock it off. So, I purchased a pack of zip ties and got to work attaching the shelves to the poles. Attach them in the front and back. This way they are not going anywhere!
Add a Floor
I put my greenhouse together over grass. I did not want it to end up a mud pit, nor did I want to have to keep trimming grass every couple of weeks. I picked up a few bags of mulch (I think I used 4) and created a floor. First, I lined the bottom with cardboard from boxes and covered it in a nice thick layer of mulch. I also bought one 6 ft strip of landscaping trim, and put that across the bottom of the doorway to hold the mulch inside. I was only using the bottom rack for storage anyway, not plants, so I covered that too.
Use Bricks Around the Perimeter
Use bricks around the perimeter of the cover to hold it down, and keep critters from wiggling under. I also put a couple of bricks on the bottom of the door when I zip it up at night. This keeps the wind from sneaking under and causing it to unzip and flap in the breeze.
These are all things that I did to my little greenhouse last year to help it survive. So far, it is still standing through a Chicago winter full of wind and snow. However, I have a few more plans on how to beef it up even more for this summer rather than get a new one, since I already have the frame I want to put it to use. I will be sure to share that when the time comes.
I hope this helps someone strengthen their little greenhouse and keep it from blowing over into the neighbor's yard. Happy gardening!
NICE POST!
