  A. konjac problems
From: "danny wilson" <mudwasp_ at hotmail.com> on 2004.09.16 at 00:12:37(12199)
Ever since ive been growing A. konjac (about 3 years), not much has happened with the bulbs. Even ones that i have ahd for 3 growing seasons have put on absolutely no tuber mass at all. They usually come up mid winter and grow until mid summer. Is this too short a period of time for them to do anything? What is going wrong?? I desperately want to see a flower, and i am no closer to getting one than i was 3 years ago.

HELP!!

Fertilize. Fertilize again. Nitrogen, nitrogen, nitrogen. Then, when you
think you have fertilized too much, you have only just begun. Fertilize
some more, and more, and more. Feeding weekly is probably only a light
appetizer, something like those silly rice cakes my macrobiotic friends
keep offering.

Osmocote or the like is not going to cut it. Osmocote only lasts the
stated time if temperatures are rather cooler than Amorphs prefer. You
are going to have to mix up some liquid fertilizer and give it to your
plants very frequently.

And, how big is the pot? Would you expect a 600-pound person to live in
an Aston-Martin coupe?

Danny,
I don't know what your soil is like but my konjacs like to be deep (over a
foot down) in very rich, moisture holding, but still loose and friable
soil. Mine is composted manure and leaf mulch worked into a sandy base. Try
digging some up when dormant, and when showing renewed growth, place at the
bottom of a very large pot (new tubers form on top of old ones) with this
soil, or at the bottom of a deep hole and cover over with this. Fertilize
the hell out of them as the shoots arise and fill out. All my Amorphs (and
Typhonium) don't show leaves till late June/early July, though they may
bloom earlier, and are usually killed down by frost late October.

it was a 5 gallon pot and a bulb the size of a soft ball. the bulb is now the size of a baseball. so fertilize 3 or 4 times a week with extremely high nitrogen fertilizer? i heard somewhere that phosphorus ritch fertilizer is good too. waht do you think?
thanks for the help so far!

Hi Danny,
First, tell everyone your growing conditions. Pot or ground? type of
soil? What zone or part of country? Sun, shade, ?? Watering and
fertilizing habits?
Anything else you can think of.

I am in Minnesota between zone 4 and zone
3 and I have had my konjac (my first Amorphophallus) for only 3 years, but each
year it has increased in size & number of offsets. I have put it in a 5
gallon pot on my deck facing south. I keep it moist and fertilize regularly (every
couple of weeks). I have used a 15-15-15 and alternating with miracle gro and
have even thrown in some super phosphate now and again. I wait until the frost
kills the leaves and take the bulbs out and clean and dry them until spring
planting. I can’t say I know for sure what I am doing – but so far
so good.

I'd say you need more sun.

I had real good luck this year using half miracle grow potting mix with half generic potting mix. I mixed that batch with what to my eye looked to be enough perlite. I started it out in my garage so it got a bit of warmth. When it was fully leafed out I started with miracle grow 15/30/15 and then sometime in august I changed to super bloom 10/50/10.
my 4 inch, one pound tuber grew to 8 inches and between 4 and 5 pounds.
I am a newbie with this plant time will tell if I continue to have as much luck
