Climbing french beans

Well they were planted out on 5th May and are about 7ft now. Would they grow to 14ft by end August if the support was there, may be 10ft would be possible. I think this year I'll do what Sarriss does but next see if any of the bamboo shoots look sturdy enough for a 10ft frame - but then I don't have any 10ft netting.

Apparently neither do I! Someone's been in my shed and took the black netting that was that long. They left the knackered green netting though, so I've made use of that for now, and ordered more on fleabay. I invested in proper enviromesh, two huge pieces and I think that will be enough for what really really needs to be protected.

Do you have any recommendations for netting that isn't quite as expensive as that, that would be ok around larger bushes like black currants etc? I will need fruit cages at some point up there, because this is the second year in a row that most of the currants have gone to fatten up the birds.

For fruit cages I was thinking I could buy some battens and paint them with wood preserver before screwing them together into frames - how does that sound?

I don't net my beans. Should I?
