So a friend had this since March just sitting around after she bought it..it had already bloomed.Not knowing what to do with it she gave it to me ~grin~ I do not know what to do either...do I pot it? Can it be planted in the ground and survive? Leave it be? I would really like to save it! and see it bloom. Thanks in advance for any info : )

Is that a leaf stem or bloom stem on the tuber? If it's growing I'd get that tuber in a pot - twice the diameter of the tuber. Use a fast draining soil that will hold moisture but not remain wet. Do not cut the stem off. The tuber will absorb nutrients from the stem as it dies back.

That tuber will grow the leaf, and in turn will itself disappear. The leaf and roots during the season will grow a tuber. The bigger the tuber, the bigger the leaf it will produce. The bigger the leaf, the bigger the tuber that will succeed it. So the important thing is to assist this process by putting the tuber deeply in good well draining soil and feed it regularly. When the tuber depletes itself it'll only be the roots holding the leaf up. That's why it needs to be fairly deep. At the end of the season the tuber will draw off all the nutrients from the leaf and then go dormant.

Not sure it will survive PA winters in the ground. I'd keep it indoors for winter and when you get more plants then try a few in the ground to test hardiness. They will survive GA winters but I find it best to move them inside for winter (garage or basement).

Yeah it's getting a bit late to plant them if you have no where to keep it warm during fall/winter. Mine are in their pots around the 3rd week of May and by first frost the leaves die and I dig and dry them out.

Like this!

Deeper and WIDER. In ONE season that thing will double to triple in diameter!

Tommyr2006,

How do you get your bulbs to grow so large. I have been growing these for a few years and have been investing in more every year because they seem to just shrivel up. They are never as big the next year as they were when they were planted.

They are heavy feeders. Are yours getting enough water/food? Mine are starting to wake the past few weeks. I have one about to bloom. My 11 1/2"/13 lb. tuber actually shrunk last year to 8". Not sure why. It is starting to grow again now. Mine get early morning sun then bright shade the rest of the day. I'll try using orchid food on some of mine this year.

You could pot them now, just make sure they don't freeze. I start mine indoors since it's still real cold here in N.Y. When they get bigger you'll know when to start them, they begin to grow on the shelf out of soil!

The (I call it a growth spike) begins to grow, you'll notice it starting to elongate.

I give them pleanty of water and try to keep them moist. I live in California so the days can be kind of warm in the summer. I think that I may need to fertilize them a bit more. somebody told me to use 15-30-15. I will try that and hopefully I will get my bulbs to grow a bit this year.

tommy - are they heavy feeders even before the tuber is depleted?

Heavy feeders through the growing season. Not sure what you mean by "before the tuber is depleted".

okay, that makes sense. thanks!

i thought that the tuber was consumed to form the petiole and leaflets.

That's how they come up with such a rapid rate of growth. Some time ago I started a thread on my largest amorph which grew to 227 centimetres (7.45 feet) tall:

http://davesgarden.com/community/forums/t/1057398/

In one 3 day period it grew 52 centimetres (20.5 inches). That would have really been pumping the life out of the tuber.

At the start of the season they'll put out roots which act both as support and feeders. It would still pay to feed the roots that early.

flower spikes are still firm on 2 of my konjacs.. the flowers are gone now.. the other has wilted..all 3 are potted up..
i only watered mine lightly when potted up..im not going to water again till i see vegetative growth
im thinking that things are ok since the old flower spikes are firm..im thinking if there was rotting,
or a problem..the spike wouldnt look as good as it does..
i did "try" to polinate the flower..if i was sucessful.. do u think that could be reason the
flower spike is staying on strong??
i hope they do well..and next yrs growth cycle i end up with some big corms..!!!! :)

Probably not as big if seeds form. But you should see the cluster of berries at the base of the old spadix. The berries would still be small, but also visible. While the plant is "feeding" these berries that's where all the energy will be going. That's actually the purpose of the plant, to reach that point where it has viable seed. I'd keep the soil moist but not wet. You could move some of the soil off the top of the tuber to check it without disturbing the roots. It shouldn't be necessary though. If there was rotting the flower stems would fall over and come away from the rest of the plant.

Actually the berries, the seed is inside those. Looks like you're going to have a lot of plants next season. These are the berries I found on an A. paeoniifolius out bush about a month ago. You can see the remains of the old shrivelled spathe below.
