The best mixture depends on the species and there are well over 100 species. These plants originate in SE Asia, through India into Africa and the islands in that region of the world.

If you can acquire a copy of the International Aroid Society journal Aroideana volume 19 from 1996 the issue is filled with information on this genus. You should be able to order it from the IAS at www.Aroid.org

In some cases, articles can be downloaded directly from the site in PDF format.

In the case of specific species search the data base at the lower left corner of the page for information. It will lead you to discussions held over the past 15 years or so of many species. Dr. Wilbert Hetterscheid is the world authority in the genus and is a regular contributor to the site as well as the Aroid l forum.

This is one of the soil mixes recommended by the Bonn Botanical Garden for Amorphophallus titanum. They have grown some enormous plants.

You are in zone 10...my advice, do not make your life so complicated......put them in the ground and be done with them!! If you get a titanum then a pot is called for, but for these really common, easy to grow weeds the ground is perfect. Mine are in the ground and I'm in zone 6. Am. konjac can stay there all year, others I dig for the winter :o) Dan

ok thanks, for your advice. I will plant konjac in the ground then.

I still plan to plant bulbiform in a pot as it will save me the trouble of having to dig it up over winter. I will put it in a soil mixture similar to cacti/succulent mix which essentially is well-draining organic mix. Hopefully this will suffice.

I apologize if my post was less than clear....If you are in zone 10 (like Miami) then you can easily plant bulbifer in the ground and forget it as well. In zone 10 there are very, very few I would not put in the ground. Best of luck :o) Dan

Hi guys,

Need any advice you can offer on relocation of my amorps.

We're going to relocate in a couple of months time from NSW to QLD (Australia) and my plants are most likely to be halfway sprouting around that time.
This poses a question. If I cut the sprouts/stems off will they bounce back?

The tuber that produces the leaf is all used up by the leaf. That leaf in turn produces the next tuber. Depending on what stage the sprout is at, you could set it back a lot or actually kill it. How many plants are you talking about, and which species?
