  • Grow Salad Greens In Fall And Winter – GF Video

    Grow Salad Greens In Fall And Winter – GF Video

    You can grow salad greens in fall and winter, its not rocket science, even I can do it. Watch the video and read on below:

    Couple of key things to grow salad greens in fall and winter

    • Plant cold hardy lettuces, mustards, kale.
    • Use a mini greenhouse
    • Start seeds earlier than you think
    • Plant in your sunniest raised bed

    Luckily, most salad greens don’t do well in hot weather, they actually like cold weather. You have that going for you when you want to grow greens in winter or fall. I usually have too many packs of mescluns, greens, etc, so I drop them into a shallow row right next to my soaker hoses [video here]. Fedco sells fall and winter salad seed mixes, which make this even easier.

    Be sure the seed rows are on the sun side of the soaker hoses. The way my raised beds are oriented, one side of the hose gets more sun than the other, so I drop seed on that sunnier side.

    Grow Salad Greens In Fall and Winter

    The other key ingredient here is a mini greenhouse, aka hoop house, to extend the growing season [how to videos here]. The mini greenhouse will keep the plants warmer in the fall and early winter months, and can extend the season greatly.

    If you don’t have a mini greenhouse, you can surround the salad greens with hay bales. Lay an old storm window over the bales. The bales will hold in the heat nicely.Grow Salad Greens In Fall and Winter

    In the northeast U.S., where we are, the salad greens will eventually freeze, and stop growing. But if you can manage not to let the frost melt and drown the plants in late winter, you can get the salad greens to start growing again. They may bolt, so plant new seed as well.

    Mini Greenhouse Build #1 – GardenFork.TV

    This is the first mini greenhouse build we did and we learned a lot. We have built several more since, and they are great garden season extenders. I start my salad greens early and can keep kale growing into winter with a PVC mini greenhouse. Watch the how to video:


    A few tips on the Mini Greenhouse Build

    • You can use 3 mil clear plastic from the hardware store.
    • Buy the most flexible PVC tubing you can find.
    • Be sure to have plenty of staples for the staple gun.
    • Use at least one thermal vent.

    mini greenhouse build

    You can get a UV resistant greenhouse plastic, but I don’t. My thinking is a tree branch or dog is probably going to crash through the mini greenhouse before the plastic is broken down from sunlight. Be sure to double over the plastic where ever you are stapling it to the frame. Where the plastic wraps over the edge of the plywood end, you can run duct tape or a slit rubber hose over it to reduce the chance of tearing.

    watch more mini greenhouse vidsThere are several kinds of PVC pipe available. Go to your local hardware store and test the different kinds to see which bends well for the size greenhouse you are building. Pick up some pipe holder brackets from the electrical department of the store to hold the PVC to the wood frame.

    mini greenhouse build

    Buy more staples then you think you need. I always run out! Hammer in any staples that don’t go in all the way themselves. Fold over the plastic where ever you staple it to reduce tearing.

    Thermal vents are key here. The mini greenhouse build can overheat easily. I use at least one vent, if you use two, put one high and one low on opposite ends.
    Buy the vent here.

    If you are building this to sit on top of a raised bed, make the dimensions slightly smaller than the raised bed size, so the hoop house will drop just inside the borders of the bed, makes it much easier to deal with that way.

    Hoop House Cold Frame #2 – DIY GF Video

    Cheap Cold Frame How To – DIY GF Video

    Here’s a cheap cold frame you can make out of scrap lumber and a window. In this video I’ll show you how to build the cold frame in a few hours. With this rig, you can do some winter gardening, and of course we have some videos on that, the links are at the end of this post.

    Some enhancements I’ve done with we made the video:

    • I painted the cold frame with outdoor latex paint, 2-3 coats is good, as plywood does not like to get wet, you know.
    • I split open some old garden house and slipped it on the bottom of the cold frame to keep the wood out of the dirt.
    • I’ve grown vegetables in winter for several years. Neat.

    I’m betting you can find enough scrap lumber to make this a recycle or freecycle project. The wood doesn’t have to be finish grade, and one of my pieces was warped, but it worked anyway. The hinges I had laying around, and the only thing I had to buy was the thermal vent.

    What grows well in a cold frame? I grow cold hard salad greens and kale. Kale will grow in snow. I’ve dug it out of the garden and its still green in February. You can buy winter salad green mixes from the seed companies. Mache is a neat green that not many people grow, the seeds are kinda tiny.

    cheap cold frame

    If you don’t get the auto vent, you will have to open up the frame on warm days. You will be surprised how hot it can get in a our cheap cold frame, even if it didn’t cost us any money to build.

    The biggest problem with this rig is the glass. It can break. That tree limb could have landed anywhere, but it landed on top of your super cheap cold frame instead. I have replaced the glass once. Luckily I had some spare windows that I salvaged a piece of glass out of. You might try putting some screening over the glass to protect it. Just a thought.

    Below are some suggested books for winter gardening, let me know your thoughts.

  • Cold Frame Gardening at BBG – DIY GF Video

    Cold Frame Gardening at BBG – DIY GF Video

    Cold frame gardening can be done in the Northern climes, as we see at the Brooklyn Botanic Garden. We made this winter gardening video at their demonstration garden in December. They were harvesting greens like arugula and mache. Watch the video and see for yourself. Below are some book recommendations for winter gardening.

    The cold frame plans for this set are easy to build. The dimensions depend on the size of the windows. You may already have some windows, or a neighbor may be replacing their windows and you can grab a few of them. Or pick them up from a garage sale or look on the web for free stuff.

    The cold frames in this video were built with 2×8 or 2×10 lumber, but you could use something less thick and it will be ok, i think. I like how they had the cold frames next to each other, so each frame helped insulate the one next to it. You could use scrap hinges off some old doors, its a ‘use what you got’ kind of project.

    For cold frame gardening, its best to orient the cold frame so it faces south, if you are in the northern hemisphere. This cold frame is manually vented, meaning you vent them by opening them up and closing them yourself. You could install the thermatic vent we have used in our hoop house greenhouse plans if you like.

    What to grow when gardening in winter? Cold tolerant plants, mainly salad greens work well. Several seed suppliers sell winter salad mixes, they will do well until it becomes just too cold. But then those plants will revive in early spring. Many times there is enough moisture in the ground to keep the plants watered, but keep an eye on them. If the cold frame gets too warm, the soil can dry out. And you’d be surprised at just how hot a cold frame can get in winter.

  • Hoop House Cold Frame #2 – DIY GF Video

    Hoop House Cold Frame #2 – DIY GF Video

    This is the second DIY Hoop House Cold Frame we have built in our video series. Easy to build, this mini greenhouse allows you to grow plants in winter. Watch the video here, plans and photos are below as well as links to our other DIY Hoop House Cold Frame Videos.

    This cold frame uses a wire mesh that’s usually used for concrete, but it works really well as a cold frame form to hold the plastic up. I like how it works
    You can buy this concrete reinforcing wire at a local lumber supply yard. It comes in two thicknesses, you want the thinner gauge wire, the thick wire is too much, I think. This wire also comes in rolls, but the it is a pain to work with. The mesh I bought was 10’ x 5’.

    hoop house cold frame plansTo cut the wire mesh we use a right angle grinder with a metal cutting disc. Be sure to wear ear and eye protection and wear gloves while you’re handling this material, it can cut your skin.

    hoop house cold frame

    Be sure the cut end of the wire mesh faces the plywood end, else the plastic can get sliced by the sharp ends of the wire. You can put pieces of old garden hose along the end of the wire mesh where the plastic bends over to form the end wall, as well as on the plywood end to protect the plastic from the hard edges of the wire and wood.

    But you can build this! It’s not hard and I really like it. Another great version of the hoop house cold frames that we’ve built, we have a whole series of them – link here – and every time we make one we get better and better. The super cool part is that you can extend your growing season in the fall and you can use one of these cold frames to warm up the soil in your vegetable beds in late winter and plant seeds even earlier than you could normally. Cold frame hoop houses are especially good for salad greens, radishes, sugar snap peas – plants that are cold tolerant.

    You can use scrap wood to tie the corners together, or use brackets.

    thermatic-vent-hoop-house-cold-frame

    The automatic vent that we use is kind of a specialty item but that they’re not that expensive. Here is the link to buy it.

    You could put one vent in or you could put in two vents. With two vents you would put plywood at both ends of this cold frame. Having a vent on both sides allows more warm air to exit. Cold frames can get quite hot, you don’t realize how much solar energy the sun has even in the winter. You will need to vent the hoop house, you can go out on sunny days and manually vent it if you want by lifting up the cold frames, but I’m not there all the time. So I like the automatic vents.

    PVC Cold Frame Hoop House #3 – DIY GF Video

    PVC Cold Frame Hoop House #3 – DIY GF Video

    Easy to build PVC Cold Frame Hoop House is a mini greenhouse that allows you to grow salad greens and cold tolerant vegetables into the winter, and get a head start on early spring planting. This hoop house is more resistant to heavy snow than our previous versions, listed below.

    This is version 3.0 of our cold frame hoop house. What I like about this one is that it’s a taller than our previous cold frames, so you could start to grow tall plants like kale or start sunflowers earlier in the spring.

    hoop house cold frame plans

    PVC cold frame hoop houseA couple things to keep in mind while you’re building this hoop house, especially if you are using this on raised beds. You want this hoop house to fit just inside the walls of your raised bed. I made this mistake when I made my first hoop house, I didn’t measure how wide my raised bed was and the cold frame didn’t fit exactly. Experience has once again taught me something. The frame fits just inside the wooden sides of the raised bed and it doesn’t have to have a super tight seal with the soil, you do want some air exchange in and out. What the hoop house is doing is moderating temperature. When it gets really cold outside, it’s going to be cold in there but it will extend your growing season.

    Consider planting some cold tolerant greens in August, I like a salad green mix that sold by Fedco seeds. They have  a fall and winter lettuce greens mix and that’s worked really well for me.

    One thing I did not mention in the video is that where the plastic meets the plywood ends of your hoop house, the plywood can cause the plastic to tear and so you might want to put something soft around the edge of the plywood. If you have some old garden hose you could split the garden hose open and run that along the edge of the plywood and that would go a long way toward making the plastic such that it wouldn’t rip.

    For  this 8′ x 4′ cold frame I used:

    • Two 2×3 8′ long studs
      Two 2×3 studs cut to 45″ long
      One 1×2 8′ stud, you could also use a 2×2
      4 metal angle iron brackets
      3 pieces of 1/2″ Schedule 40 PVC cut to 6′ long
      1 1/4″ and 1 5/8″ drywall screws
      Two pieces of 4’x4′ thin plywood. You could also cut down a 4’x8′ piece.
      3 or 4 mil plastic, i used a roll of 10′ x 25′, which is enough for two hoop houses.
      Two thermatic vents, available here http://amzn.to/2Cg81fg
      Staple gun

    Using the angle brackets, build a 4′ x 8′ wood frame, make sure the shorter pieces of 2×3 wood (the 45″ pieces) are inside of the larger pieces, so the outside dimensions are 48″ x 96″

    I cut the plywood ends to match the arc of the pvc hoops. Take one of the hoops and curve it into the wood frame at the end of the frame, and use this to sketch the arc on the plywood ends, it does not have to be perfect.

  • Seed Starting in a Hoop House Cold Frame : DIY Video

    Seed Starting in a Hoop House Cold Frame : DIY Video

    Starting seeds in a hoop house cold frame is like putting a greenhouse on your vegetable bed. The hoop house warms the soil and then you drop seeds right into the soil. No transplanting or grow lights, no transplant shock. This is our cheap PVC hoop house that can be made with salvaged or recycled materials, and then you can grow vegetables in the hoop house. What I love is how the cold frame warms the soil to 15F above the ambient soil temperature.

    Plants that do well  for seed starting in a hoop house are those that are cold tolerant. What the cold frame offers is a warmer soil and air temperature, which aids in germination. Yes, peas can be planted in snow, but they germinate much better in slightly warmer soil, same for lettuces and cabbages like kale, just a bit warmer and they sprout better. For this video I put sugar snap pea seeds in and radish seeds. Radishes are one of those seeds that are kinda fail-safe, so you feel ok even if some of the other plants didn’t take as well.

    hoop house cold frame plansWe have several videos on how to build a hoop house cold frame and how to use a plastic greenhouse like this, here is the video of us building our first cheap hoop house. I think its key to have the thermally controlled vent, if it gets too hot, you might consider putting a vent on each end of the hoop house. The PVC we use in this cold frame could be salvaged or recycled from another project or job site. The plastic we use is 3 mil plastic from the hardware store. With care this plastic will last several years. In the middle of summer, I hang my hoop house on the back side of the woodshed, and the plastic stays in good shape for a few years.

    Repair Of Our Hoop House Cold Frame : GF Video

    Setting up our simple cheap hoop house greenhouse for seed starting. This PVC hoop house cold frame works well for us and it was easy to build, here is the video of us building our the hoop house. The hoop house greenhouse allows you to get a head start on planting vegetables and seed starting. We started this in February to start warming the soil. This can be made for free if you find some scrap leftover lumber and PVC pipe. This plan uses short lengths of PVC pipe, which you may find laying around your yard, or your neighbor’s yard.

    My hoop house plans for this mini greenhouse are simple. Some 2x4s, some PVC pipe, and a piece of plywood. The thermal actuated vent keeps the hoop house from overheating. Link to buy the thermal greenhouse vents

    I use 3 mil clear plastic from the hardware store, it lasts a few years with care. I hang our mini greenhouse on the back of a shed when i am not using it. To attach the plastic to it, I fold the plastic over on itself and use lots of staples. You could also use a piece of lath or thin wood to hold the plastic to the wood. For the ends, I staple the plastic to the plywood end with the thermal vent and then cut off the excess plastic. For the other end of the cold frame hoop house, I simply bunch up the plastic and staple it to the 2×4.

    After a few days on your vegetable bed, this portable greenhouse will start warming the soil. Its amazing how warm it is inside the hoop house compared to the outside temperature. We have a video showing how a hoop house greenhouse can defrost your garden soil coming soon.

    In the video, the plywood I used for the end of the greenhouse, OSB, is not the best kind of plywood for outdoor uses. Use a better piece of plywood and paint it with a few coats of latex paint, it will last much longer if its painted.
