Sorry spuds. Mea culpa. I thought I was doing you a favour but, in fact, I was giving you too much of a good thing. Nitrogen, I mean. An essential nutrient, yes, but too much of the stuff and you were all about the above-ground show of foliage, with nary a thought for the tuberage down below. No, you were not to blame for the low yields and I, for my part, will know better next time.
