They are already at the top of my 5m trellis and I fear they will be swinging in the breeze and potentially snap off if I let them keep going .
Can I tip them (cut the tips) to restrain vertical growth and promote more vertical bines or could this introduce infections. I haven't fertilised since the start of the season either.
