Am thinking of buying a "Gardman" polytunnel...My allotment is quite

and have any thoughts on my ideas ?

When covering or recovering poly tunnels we used to trench along the
sides, making a square sided trench, then bringing the polythene down
into the trench and back out, the trench was then back filled with the
soil traping the polythene against the trench walls.

I have a very strong tunnel from Northern Polytunnels in Lancashire. I
live in Caithness in the far north of Scotland and it has survived five
years and two hurricanes with the original poly. Having trenched in the
same way as Dave, I doubled the poly back over the soil and then covered
it again, making a double layer of poly and filler (no pun intended).
My tunnel faces North-South. This is in my experience not ideal and I
think that an East-West direction would give better results.
