Along my wooden fence I have 4 wires which support my blackberries every year. The bottom wire is 2 ft off the ground and the others 3,4 and 5 ft.
I know I could fix another above these but can I cut down the distance between the wires to 9 inches each ? 1 ft gives plenty of room but 9 inches would give me an extra wire which I really need this year.

Hi Hank, yes the blackberries wont mind at all, Derek.

I agree they cant count! they use the back facing thorns to help them 'climb' in the wild.

Thanks, got it. But no thorns on mine SG, completely thornless.

It's all right...the thornless mutations don't know that they are "special". ;)

Hi Hank, they're your wires, you can have them wherever suits you best, it won't make any difference to the blackberries, Derek.
