I think I asked the question, how sensible is it to build a polytunnel on a windy hill? well, I got my answer this weekend. 60mph winds tore my 6 concrete stansions out of the ground and my tunnel took off like a kite!
lucky we saw it going and were able to salvage some poly and stop it crashing into our neighbours house further down the valley.just needed a shoulder to cry on for a sec.

but the motto is def- 'we shall overcome'- new plans already for a stronger frame with more cement to stop the wind from lifting the frame- steel re enforcement bars etc.

my neighbours bless them thought I was nuts for building it in the first place (sheep farmers) but came running to help when they saw it going and still managed to keep a straight face- the joys of the scottish weather!

Is there any way of making a section 'tearable' to allow the wind to blow through a gap without lifting the staunchions?

Hi Ian
not this time- the direction of the wind caught the whole side toppling it over rather then hitting the opening ends. I guess we could batton it mid way but that just leaves another seam for the wind to creep into- we thought it would be fine but obviously there was a gap between the ground and the poly- next time lucky!!!

Oh dear, poor you
My greenhouse was damaged in bad gales a few years ago, thank goodness that didnt fly off all together but rather was hit by flying debris (Its a twister Auntie Em!)
Can you put up a windbreak? Hedging is better than the commercial stuff, more permeability, if it wont create too much shade.

That's not a bad idea - how about blackthorn, then you'll have sloes at the ready for sloe gin! We planted a mixed hedge of blackthorn, white thorn and beech - and it was beautiful, and fast growing.

there was an amazing wind here too the other day.
I saw a great windbreak planted in a permaculture garden recently. It was several big limbs of willow - about 4 foot high from the ground which had been planted in the spring and sprouted immediately resulting in a 7 foot wind break. The only difficulty will be getting from now until the spring.
