  Pycnospatha arietina - a problem
From: "Marek Argent" <abri1973 at wp.pl> on 2008.12.22 at 02:32:51(18791)

Hi all,

Last year I bought one tuber, it produced a leaf and fell into dormancy as it should (I cultivated it at home).

This year it hasn't put any leaf or roots. Yesterday I dug it from the pot and I still don't know if it is alive or not.

I scratched it a little - it was cream beige inside and seemed solid.

I broke the tip where the leaf should grow from and it was wet.

How to check if it is not rotten? What to do with the tuber?

I stored it during dormancy also in the room temperature.

Here are 2 photos, I can do better images if neccesary (macro closeups).

Please help me

Hi Marek,

Oh, you will definitely know if it is rotten. Pycnospatha collapse very quickly and smell horrible. Your tuber still looks good to me.

Hi Marek and Susan,

They smell bad only depending on the pathogen that caused the rot. I'd
like to see a better photo taken more from the side. And please blow or
brush off all the soil that you can. But even with a good photo there's
no substitute for a hands-on inspection. You really need to use your
best judgment about the tuber's weight for its size, the firmness and
whether or not it looks dried-up (dry rot is common).

Unfortunately it was a mistake to scratch through the skin. I've found
them to be extremely picky about even minor damage. You said that you
stored it at room temperature, but it was in soil, right?

I think it is still alive, Marek.

Hi Marek,

Amateurs probably kill more plants by poking at them and seeing”if they have come up” than die from any insect or disease. If itseems firm, why not just put it back into the pot and wait patiently for thegrowing season.

Hi Derek,

It is December so I was really curious what happened.

I never pull out tubers when they are in the growth season.

Hi Marek,

I wasn’t particularly pointing at you, although Isuppose it was your pictures that made me remember the other postings that havecome in wondering what to do with dormant tubers. We are in a favouredsituation in South Florida, but I definitely practice what Ipreach after all my years of disturbing perfectly happy plants who just want tobe left alone! Not to mention digging up seeds to see if they are sprouting!

Good luck with this one, which looks fine in your pictures.Remember that the plants will tell you when they want to grow. Plants can tellyou an awful lot if you let them.

Best Regards, Derek
