Quick Dahlia question
Last year I planted two dahlia tubers, one of which was snapped and broken and the other which was perfect. In the end, the opposite of what I expected happened - The broken tuber grew into a lovely flowering bush whilst the 'good' one never appeared at all.
I recently turned the soil before planting new bulbs and there was absolutely no trace of the tuber that never grew. I cut back the one that grew to a stalk, currently have it in an old shoe box and am looking for a new spot to plant it, but what happened to the other one? The soil was never disturbed, so nothing dug it up. Did it just rot away into nothing? Why would a perfectly good tuber just disappear like that? Both spots got the same water and light.
