Over the last couple of years we have noticed that germination has been very sporadic, my father had to sow three times this year! But also, many of the vines have grown way past their normal height - up to six feet or so. The pods on these longer vines are short, and don't seem to fill out, but stay small. We have tried several different suppliers to ensure that it wasn't just a bad batch.
Is anyone else noticing this problem? I am wondering if this particular variety is reverting back to it's parent?
