Hello

I bought last year three big Typhoniumknollen with flower buds me, all three thrived very well last year and formed many primary Cormels.

And now for the bad luck:

Already in the winter two of my three large Typhoniumknollen of pests were attacked, first there were small ca 1 cm long maggots that ate holes in the tubers, when I took the maggots the holes grew still further in depth.

When I brought the largest tuber from the cellar now in spring a tiny only 14 cm wide flower came out, which surpassed thus just the diameter of the tuber.
The eigeartige this was only the flower before the blossoming vertrocknete and so after the blossoming exuded a stench.

I then placed the other two large tubers in the gardens where they now stand.

Recently, I noticed however that was a hole in the shoot of one of the two tubers and the flower bud has been gnawed off up to the peduncle of any animal.
The comic it was but that the Blatttrieb which is Yes immediately next to the flower bud, since they both were still in a bract, was not angerühr.

My last hope to experience even a Typhoniumblüte this year is now in the garden and is my last large tuber.
It grows at the moment but also only still sparsely, but shows no damage.

If anyone has some tips what I next year should - do better just to.

With kind regards
Stefan

Hello

I have cultivated the plant has always been in the pot, the pests have already occurred in the basement.
Also, only the large tubers were affected, the many small Cormels were not affected.

Hello

may be the odd is that only two of the three large tubers were infected even though they had exactly same conditions - but, and even the large tubers were affected, not the small, even though they are in the same pot.

This is a mystery me everything.

With kind regards

Hello

Yes the old ground was still off,
but I've had all tubers in the old soil, the primary Cormels.
And as said only two of the three large tubers are affected and no primary Cormels.
I had but three large tubers jewils in three different vessels in which only the Earth from the pot in which they were located.
I had left the primary Cormels in the soil in which they are grown, they were also in the same container as the mother tuber.

The infected tubers but just looked like yours.

Since there seems to be a "Typhonium-nut root Eater" probably.

I have again today, the most infected tuber (which is where dried flowering) dug out and seen that it makes roots, so still it seems to be what.

Hello

This larva was not determined, because that were small and white with me, like a mealworm it not looked determined.
I have not seen the beetle, but I think that it was fly larvae.

Hello

Unfortunately I can remind me of the larvae.

At least all tubers have survived, one will probably soon put a fourth hand.



I have now a different guess:


The great Typhoniumknollen have a very rough surface covered with cracks, but the small have a pretty smooth surface.

The large are therefore more susceptible to Putrescence, if they are in a damp basement.
Then the eggs of the larvae hatch, as they sense moisture by the Putrescence.
Because they have to eat anything else they make produced of the tuber.

Hello

the old tubers have I also removed, as well as the new washed.
I have it but all adjacent. So far nothing has happened.

All power, a pretty strong, it is probably that which last year has also been > driven.

When the harvest I have no bugs discovered.

Last year have I but also the old tubers drang leaving and that I move the blame that two of the three tubers were almost eaten up.

Before last year, the infection has occurred but only in the spring.

With kind regards
Stefan
