Wind keeps removing polytunnel cover

[goodolpete]

I’ve got a cheapo 3m by 2m plastic polytunnel in my allotment.
I went there today for the first time in a week to find the
cover off for the third time this winter. The frame is jubilee
clipped to six broom handles driven into the ground, so is
solid as a rock, and the cover goes over, leaving an 18” flap
all round on the ground. I’ve been piling old paving slabs, huge
rocks and what have you on these flaps, but obviously it’s not
enough.
Have any of you dear experts got any whizzy solutions as to how
to make a cover unremovable please?

Bury the flaps. Or staple them to sleepers or something?

Throw ropes over the top and peg them down - like tent guy ropes

I had my tunnel raised on 4"x4" wood and I fixed the cover to them by using a baton screwed down so the plastic was sandwiched between. Since yours is already up, I would get lengths of timber (at least 3"x3" imo) and wrap the bottom of the plastic round it once, fix with batons, then let it fall into a trench which you can then backfill and also slab if you want to. The plastic ends need weighted, I don't think it's enough just to cover them over.

Only imo of course.

Thanks for all your replies. Has anyone got a good method of fixing internal
ties to plastic, so that I can tie the cover to the frame to help it keep on.
I suppose the alternatives are either glueing them onto the cover, or, as
was mentioned above, sandwiching between wooden battens.

Sandwiching between wooden battens really works. If you can, do that around the bottom, around the whole thing too.

Attach a batton to the broom stales you have driven into the ground, perhaps using p-clips, then screw another batton to that, sanwiching the cover between the two in the process

As veggiechicken said secure ropes to old broom handles, thread old hosepipe over the rope and tie down. The hosepipe takes some friction out when rubbing on the plastic cover another good idea is to use double sided foam tape on the pressure points to prevent holes being made, works great I have a 6 by 3m polytunnel on a windy plot..
Root anchor chains holding the frame into position and 4 hosepipe lined hoops holding cover on and has worked like a dream plus nice and cheap and no damage to cover
