I find their newsletter good although the instructions are sometimes so complicated...
They were talking about gooseerries this month. They say you can train them up an espalier. Honestly how do you do that???? They are so prickly, I can just about trim them but no more without ripping myself to shreds (yes even with gloves.) I would love to do that but I am no DIY person so building teh trellis is out of my league. Would be nice though, my goosegogs are now 5 years old and tending to spread out rather than up!
