Hi Sonja,.
I use the extratropical types always my the same airy standard mixture (ordinary potting soil with 30% lava stones). In tropical species, I have had the best experiences with pure Kokohum.

Whether it makes sense in lime-loving species to add another shell grit, I'm stumped. (What kinds would it?)

I would try it with some tubers in your place, you over did and see if it brings what.
Many Araceae are much substrate more independent than you think in my experience.
Here everyone in the Forum will have as its own mix with which it works.
Many greetings
Ortwin

I have a drainage layer of marble or limestone chippings, or granite or lava stone in each pot below, depending on which soil in which nature is preferred, if known. The eburneus group is pronounced as kakliebend (except infundibuliformis). If I'm not sure then I tend to lava or a mixture of the lack of lime is less wachstumshemmend than a too much lime types, who do not tolerate him. Mix I don't the lime, because of the split is very sharp and I'm afraid that the tubers this could be hurt. In addition, the roots grow down anyway.
Love greetings

Hi Sonja,.
I had in this regard even an interesting discussion. Then it went to Helicodicerus... a good friend told me that this way although grows in calcareous porous regions there but only in humus-rich column and holes.

Before that I planted my Helicodicerus in very sandy, calcareous soil, however, despite weekly fertilization and adequate light was growth the tubers pathetic. Also I mean to have read already, many with a humösen mixture are successful. Lime as an Encore is probably not a good idea.

Among the carnivores there are species that grow very calcareous soils. But in culture it has not proved, to use appropriate mixtures... It is often sufficient to ensure good light and appropriate temperatures.

Michael's approach with the drainage layer may be a solution. Here, it would be good if you would compare.

Greetings Ralf

Happy reading, Bernhard.

Bernhard as there are several articles.


Edit: Seems good

... that's right, I had neglected to write, that's the 3rd article, if I remember right...

Thank you Bernard for the source, exactly what I was referring.
eburneus and juliae grow very well with marble drainage in Sphagnum; hope it stays that way.

I've never tried Sonja, clay, I'm afraid, that the substrate of ´ compressed too much me (can but be wrong). I'd take the granules. Clay powder is simply dried clay, I guess?

Thank you Thomas, it's not clear to me. To layer silicates, there was I think a very informative post regarding Seramis times, have not found but now on-the-fly.

Hi Sonja,.
Confusion is always good! "Loamy soil" to read which of the properties for the plants are really critical, but are never, It is the actual composition of the metal ions, the consistency of the clay, or in contrast to limestone/limestone only the tendency in the acidic or alkaline milieu... for my household, I will limit myself to the latter. So much confusion!

I would like to revive this topic!
I recently spoke with an acquaintance about whether I should add lime to the substrate for my Hoyas or not, many of them come from limestone regions and some of them grow on it. He said it wouldn't really matter if the other conditions were right.
Now I am new to the field of Amorphophallus and wonder if there are any more opinions here about lime in the substrate for certain Amorphophallus. Hoyas also like to grow epiphytically and that they may not itch so much seems conclusive to me. However, an amorpho has its most important part in the substrate - so that shouldn't be decisive?
Perhaps someone else has a request to speak on this, I would be very happy!
Greetings,
Emily
