Überwinterungstemperatur von Knollen, welche kalt und trocken überwintert werden sollen

Hello


I have overwintered tubers this year for the first time. I would like some questions: I now noticed that to a pretty dark color have adopted some tubers. They have become darker than at the beginning of the rest period and as the tubers, which are offered as on ebay, etc. Could the a mushroom be?


Unfortunately, I have currently no digital camera, I can only take a picture in a few weeks.

What surprises me stay, the whole tubers (also konjak and Typhonium venosum and giganteum, Arisaema) make to drive yet no move, if I so look at your tubers, which bloom all have long...

I am thinking now whether it may be that the tubers to cold had this winter? Is there something like a minimum temperature, which must not be lower than in winter? -I think I had read in 10 degrees, but are likely to endure in konjak etc significantly colder?

I don't know how cold it was in the basement, but we had 20 degrees this winter for a short time - out, since it can be that it was only slightly above the freezing point -, for a short time

Some tubers have woody, hollow bodies and have dried (Typhonium giganteum for example) :motz:

I keep all my tubers at room temperature. The most Amorphophallus come from tropical climes and I can well imagine that floor heating in some species plays a role in the 'waking up'.

Are these temperatures, one reads for konjac & co., I don't think as a set temperature to understand, but as a minimum temperature for people who have the plants in the garden or greenhouse. Unlike tulips or daffodils, you must not cold store which (Amorphophallus) tubers, so that they not cast out.

What's the color, a darkening is normal. If you dig up the bulb directly after the leaf falls off, it is sometimes still completely white. Then it darkens over time and almost formed their "skin".

Shrivel or rot she shouldn't but, then something is not right.

About shrink and BB´s a discussion was lazy in the lost Forum.

Main cause was, in my opinion, lack of cleanliness when storing the tubers in the fall. So had pests (worms, bugs...) free months to destroy nodules before they entered or disappeared.

I have stored my tubers in a pile at the time and many very lost. After I washed them first in a Chinosol solution and then separated yogurt store cups etc., without losses.

So I stopped - too much work. Now sink I them only after the crops with the garden hose off, keep them separated and lose a few tubers "only" every winter.

Thank you for the detailed answers. I think it's probably a combination of everything. On the one I keep the tubers likely to cool, I did now they in a room, which is probably cold in winter always at 10 ° C.

I never washed have tubers, I thoroughly knocked off just getting the Earth. It can't also be that this pests on the tubers have passed. :icon_explode: I'm going to wash them in the future.

Although no Amorphophallus, but the tubers of Sauromatum venosum in me always look like:

There's nothing washed. Which I have always just off dry, but knocked off the Earth. When the drying is by AB gebroeselt alone.

No only the normal. The Brummer have only 9, 5 cm and 14-15cm in diameter and weigh 750 g and 325 g at the time of the recording. But even in smaller tubers leaves in maximum size (based on 70 cm high and in diameter). See also the 2018er flowers thread. The tubers have become in the course of time but still clean. Which were still not completely dried, in particular the primary Cormels below.

For the purpose of IG, you can watch friends even following thread: Typhonium venosum in original condition?. There you've got to see the real Brummer.
