Amorphophallus konjak query

Post by Eric Williams »

Hi all, removing my corm from its pot today, I noticed about 3or4 club shaped protuberances about 2inches long attached to the corm sides. I assume these are shoots for next year ? The corm is near 5 inches in diameter. Would it be possible to remove these growths (scalpel) to promote all the growth to the central point. I have read that the corm if getting large enough to flower soon. Thank you.

A picture would help, however from your description it sounds as if it is forming side shoots that will eventually make separate corms. If you feed and water it enough the main corm will still continue to increase in size despite the side growths. Personally I would remove the new corms when they become properly separated to avoid rotting the main corm.

Dont worry, Eric, they will separate themselves, probably next year.

Make sure you give the plant a really big pot, and plenty of fertiliser when growing.

Mine flowered a year and a half ago, but it produced quite a few separate corms before it flowered.

If anyone would like a corm of this, I will have one or two spare when the leaves die off (soon), which I would be happy to exchange for anything interesting. Send me a PM.

In China they make a kind of edible grey jelly from the corms.

Thanks both for your replies, will try to upload a pic.asap. I can see now what they are as you say. As Ralph mentioned, the corm forming parts of the plant are at right angles to the main corm body, and will
therefore require a much larger pot to contain them. Cheers and thanks.

Grey jelly is what remained of my plant after leaving it in an unheated polytunnel in the 2010/11 winter by mistake [emoji53] it didn't look very edible though [emoji3]

How large so these have to be to flower? I've had one getting slowly bigger each summer for three years, but still no flower...

Mine was about 14cm diameter at the end of last year (I haven't dug it up yet so hopefully even bigger now) and it still hasn't flowered. Although I keep hoping every year, so far, it's always been a leaf which appears first.

Mine was just about 4 centimeters when it flowered two years ago. But last year and this year no flowers. Apparantly they are a bit erratic?

I'd say mine was about 15cm across when it flowered.

When it did flower, I first got the flower spike, around April, before the leaf appeared in July, as usual.
