Nail finishing nails through the aligned holes in the lath strips into the wood frame for all four sections.

cloche 969Once all the lath has been secured, wiggle the lath strips and plastic pieces free of the nail so that the plastic cover can be lifted from either side and then refastened when necessary.

STEP SEVEN: Get growing! Fold back the cloche cover on warm winter days and water appropriately.

  2. Instead of pvc pipe I use 3/4 inch black poly pipe…the kind that comes in a roll used for irrigation…and cut it to length. The pipe slips over a rebar type 3 foot fence post at each end. The posts are spaced along the inside edge of my raised bed about 2 feet apart. The posts are long enough to keep the piping not only in place but keep the house from shifting in the wind. I made clips out of the pipe in the same manner. I happened to have some left over wiggle wire and track so used that to secure the plastic to the sides and ends of the outside bed. …great stuff. Poly pipe lasts forever and it won’t snap off in a high wind or degrade in sunlight. The wiggle wire makes it easy to unfasten the plastic for ventilation if required. Depending on the size of the bed/plastic the ends can lap over so one piece of plastic sheeting is all that is required (cut off any excess) as the wiggle wire will fasten several layers easily.

  3. Each year I donate a couple thousand plants to local charity plant sales and community gardens. This includes perennials that I pot up in the fall and tomatoes, etc. that I grow from seed in the spring.
    The potted perennials are set next to each other on the ground. I lay a few small empty pots on their sides with packets of rat/mouse bait in them scattered between the big pots of perennials. I put a corral of chicken wire around the perimeter of the group of pots. Then I dump a few inches of leaves or straw on top of all the pots just before it snows. When it thaws out in the spring I remove the leaves/straw.
    I start all of the tomatoes, peppers etc. in our basement in a warmed enclosure. When they get too big to live indoors I set up a couple 4′ x 20′ temporary hoop houses in the back yard. I do not use PVC for the hoops because it is not UV resistant. Instead I use 10′ UV resistant plastic conduits. The UV resistant conduit is not very flexible–I bend it into permanent hoop shapes with a heat gun (sort of like a hairdryer on steroids). What Mike says about lifting the plastic side of the house to keep it from cooking inside is vital! After all of the starts are either planted or given away the hoop houses are dismantled until the next spring.

    As they say, there are lots of ways to skin a cat.

    • Great information Jennifer, thanks for sharing your simple but effective method of over wintering plants. I should do more of what you do!

    • Jennifer: If you use the gray PVC electrical conduit (which is UV resistant) it should be just as flexible as the white PVC water pipe.

  4. I have found this web site, and also the comments of other readers to be a great source of information, and education. I have learned things here, not covered on some of the university agriculture webs. Thanks to all.

  5. Mike,
    As a would be beginner in plants and vegtables I find most of your blogs and even in the comments section from other readers to be most helpful… I enjoy reading through them all… I wish there were more of them and more ideas even… I guess everything can’t be free 100% of the time but its glad to know and is a relief that there is someone like you out here always with some advice… Right or wrong, we all learn through trial and error. Making mistakes is part of life, but when ya share your knowledge others learn to.
    Just wanted to say thanks and keep up the good work… I enjoy all your emails

  6. If you are in an area where people are remodeling you can reuse sliding glass doors and windows of all kinds . A lot better than busting them for the dump. Also you might set 5 gallon buckets or jugs full of water to grab heat and then release it slowly when the sun goes down. could also use a seed starter heating pad in there to help in cold areas.

  7. Mike,

    The PVC pipe has a reaction with the plastic and will eat away at it. Slip a barrier between the plastic and the PVC pipe and the plastic. I lost my hoop house this way. All the west side of the hoop house became brittle. There was a storm and the brittle area slit. The next thing that happened was the hoop house was lifted off the ground and was smashed to smithereens 200 ft away.

    I had real greenhouse film with a warranty on it. It was not covered by the warranty because of this (although they also DID not tell me about this issue when I bought the film!)

    I am planning on buying a pipe bender so I can make hoops of metal. In the meantime I found an old metal shelter frame and will use that .

    Keep planting !

    Kristen

    • Great piece of information. I knew the structure would grow more brittle over the years but didn’t’t realize it was a chemical reaction and so easily preventable. Thank you for sharing.

      • Cyndy: I don’t know if painting it would help but if you decide to paint your PVC keep these 2 things in mind. First the surface of the PVC has a kind of glossy finish. Paint will not adhere to it properly. Use Citristrip paint remover to clean the PVC. It is a quick and easy way to remove the gloss and prepare the PVC for paint. (Don’t get oil or fingerprints from your hands on the PVC after you clean it. Either wear gloves or remove your finger prints with rubbing alcohol.) Second use Krylon Fusion paint for plastic to paint it.

    • A neighbor had a carport that was made of plastic and it split so he had a new cover made. Before putting the cover on the pvc he covered the pipe with pipe insulation. I think that might work for this, too, and it’s not very expensive. Maybe a person could put some cloth over the pvc as an insulator between the pvc and plastic.

    • Here’s another point with hoop houses of all kinds. The plastic has to be really tight. If it can move it all it work a hole in the plastic, the wind gets in and away it goes.

    • You can bend pipe with hot sand if you wanted to go the cheaper route! There is a video on YouTube I saw where someone did it. 🙂

    • I use live stock panels.. Wire them together and walk them together to form the hoop.. For Floor fasten wire at bottom and secure to bottom other side to hold your shape.. Run 2×6 down each side to secure wiggle wire track and use regular greenhouse film.. Framed a door in on one end and window in other.. Lasted a long time.. I use the same method to tarp and form rain and shade shelters for livestock.. Not fancy but fully functional.

    • Joyce,

      It depends on what you are over wintering, but if the plants that you are growing are hardy in your zone, then the hoop house is all the protection they need. You have plenty of cold weather, but even here in Ohio it often gets well below zero and in most cases the plants in the hoop houses work great.

      A hoop houses isn’t meant to keep your plants from freezing. It’s meant to keep them from freezing and thawing, freezing and thawing. It also keeps them hydrated which is really important when they are frozen.

    • Joyce Ann: You’d probably need to keep the snow cleared off it is so that it doesn’t collapse under the weight!

      • Don’t feel bad, I’m like the king of typos, but people still appreciate the content. Every once in a while somebody goes to school on me about typos etc. But you know what? I do the best I can which is a lot better than most of my critics.
