Beautiful crop of leaves but no root to speak of. Where may I have gone wrong?
Doubtful it would be a lack of sun or water. Wondering if a too rich soil might be to blame? |

They like a good soil. Did you get enough heat? Long growing season? |

Yes, which means the crop wasn't entirely wasted!
Sun, lots of. Good soil, tick. Water, no problem. Can't remember when they went in, but perhaps they were simply not in the ground for long enough before they died off.
There's always next year ... |

days of growth might have been the trick. Why did they die off?
I've only ever seen them go down after frost |

Did you let the vines grow across the ground? They can end up re-rooting along the stems and not putting their energy into making tubers. I made mine climb up a grow string, and cut out the tops once they had reached the roof to encourage the tubers to swell. I also believe they need good drainage - the book I have says to plant them on a ridge for this reason. |

Only just seen the updates to this.
Slim, they died off following our first frost.
Roobarb, that's really interesting thankyou. Yes, they were sprawling beautifully and I did notice multiple root points. Might be a significant factor. |

So can you give a guesstimate of how many good growing days they had? |

May to November? Went in as fairly decently rooted plants, so got away fairly quickly. |

I've read somewhere that the shortening daylength triggers tuber growth but by then its getting much cooler in the UK. So autumn temperatures will affect yields.
There's also the need to prevent the trailing plants forming roots - see here under Training and Pruning. |
