Hi Sophie,.
Hello Stephen,.
well, I've frowned also, when I saw the tuber in the sandy substrate. Unfortunately I can not talk with the for the titanum responsible gardener.
But the dry storage for cutting away the rotten authorities is understandable.
This of course contradicts the recommendation titanum and co. in the rest period in slightly moist substrate (or Sphagnum) to store and certainly not for a long time so well.
Where are the nematodes?
I don't know whether the lazy bodies really on nematodes zurückkgehen, which ensure easy there, where many plants in a confined space are cultivated.
But sometimes I have the impression that nematodes in Amorpoohallus for each Faulsetell must serve so as chlorosis are attributed to viruses in other plants, if you don't really know the cause.
But nematodes are, if there are really a big problem, because as far as I know it, only a nematicide for use in Rosenkuturen (outdoor) is approved in Germany (

Therefore the recommendation very pay attention to hygiene and to cut away the infected tissue in the case.
The size of the pot is sufficient for a 14-kg bulb, which will have diameter probably to about 30 cm, safe for the flower. for the advanced culture, to reach the target of ordentliuches Knollenwachtum, he is perhaps really quite small. But maybe they even repot the tuber it or just include that the bulb through the flower properly shrinks and the pot is then sufficient.
Happy growing, Bernhard.
