Make sure you set aside a full day or two for some really hard work and back breaking labour. Don’t make the mistake we did and assume your polytunnel will be okay weighed down for a day while you get your breath back, it won’t!
Separate the work across two days. Make sure you only put the cover on when you have time to dig it in all at one go.
Get the Polytunnel erected (frame only). Make sure you have all your tools and equipment necessary and an extra person to help out. You will need someone to help carry and lift the arches if nothing else and to hold bars in place while they are fixed in.
Dig a trench where the polytunnel will fit in all around it, even if it has no base frame – you will need the trench for the cover. You can use the frame of the polytunnel itself as a guideline so you don’t need to mark it out. You will need to move the frame while you do so.
Get the cover on the polytunnel as per your instructions, you will need an extra helper for this too. Align up the sheeting and tie it down. Then move the frame into the trench if not already and ensure the cover lays down into the trench. We lined our cover with a few bricks and rocks to help weigh it down but we are not yet sure if this was wise. Next, move the soil from the trench back into the trench on top of the cover. Do the same on the inside of the polytunnel too to seal in the cover and ensure there are no gaps. Press the ground in firmly.
You will notice how warm and cosy your new polytunnel is (just like ours, mmm!) Remember to seal the doorway properly before you leave or it will serve as an entryway for the wind.
