I had read hop bines should reach the top of their trellis/pole/guidewire by the summer solstice. In years past I have never topped or pruned the tip of my bines, does anyone have expeience with hop cone output in regards to pruning the tops of the bines? hope everyone is having a good year with their bines. My centennials are around 10-12 ft, chinooks in the half barrels have hit 10feet. Not my best year for the centennials, but the chinooks may have a banner year.
