Hi there,
So it’s April and we are all hungry. Organic box schemes are good but a little light on the salad, herbs and other tasty plants you might want to chow down on a few leaves of. It is raining, so instead of showing you my (wet) results so far. I will write a quick start tutorial, as it is not too late to build a tunnel and grow some food.
“But wait”, I hear you say. “I have no space for a veg plot, and no time to look after it”. Well my time and space challenged friends fear not. All you need is a strip of earth a few feet long (yes it is space but hardly a footy pitch) some wire, and a clear plastic sheet.
That’s right, if you can find some soil we are going to build a polytunnel. If you can’t even squeeze one into the front garden, I will be writing about grow bags soon. So as long as you have a hard surface (even a path would do it) you can get some food.
So here goes:
Firstly you will need to dig the ground over and remove the roots / bits of car / glass that makes up British soil.
Secondly gather your materials. Get some wire, any type will do as long as it is fairly rigid. Garden wire is your best bet and is readily available. Even 3 core household cable can be used (if it’s the stiff stuff). You will also need a trowel / big spoon your girlfriend doesn’t know you’ve got / stick. This will be to dig with. Once you have these, find yourself some clear plastic sheeting. A large clear bin bag cut open will be fine.
Right, now for the build. The idea is to create a semi circular structure with your wire to drape the plastic over. There are many designs for this but I have a favourite that is strong and easy. As a bonus it uses one continuous piece of wire so few cuts have to be made. Get your wire and bend a few inches into a striaght bit. Turn that bit 90 degrees anti-clockwise from the rest of the wire. Now use the rest to make the first “arch” by bending a semi circular shape into it (as wide as your earth-strip). You will see (hopefully) that if the first striaght bit is laid flat on the ground the semi-circle will point into the air and curve back toward the ground. Once it is there bend another flat piece to sit on the ground. This time make it a couple of feet long and pointing in the direction you want your next “arch” to be in.
You will hopefully see that without cutting the wire you can make a continuous 3D “semitube” by growing it one arch (followed by straight bit) at a time. Once you reach the end make another small straight bit.
Now for the plastic, take 2 end corners and tie a knot to “bunch up” the sheet. Place the knot on the ground, on the outside and in the middle of your first arch. Drape the sheet over the tunnel and tie another knot in the other end to make a long semicircular shape. Now, remember those straight bits of wire you have laying along the ground. Weigh the sheet down above these and your tunnel will be steady.
Now, dismantle it a bit and start digging. Make channels an inch or so deep and a few inches apart for your seeds. I have lettuce, radish, carrot, parsnip, beetroot and more in my tunnel, your local hardware / garden shop will advise the best ones. sprinkle generously in each channel, cover with earth and water. You can also use ready grown plants. I have sneaked a few strawberry plants into my tunnel. Now you can rebuild your tunnel and admire your handywork.
The tunnel will keep the seeds warm and moist in the day and frost free at night. After a few days you will start to see a few shoots, make sure if the channels look dry you water them. I water mine every week or so at the moment.
As soon as the weather clears up I will post my results so far.
