Not just for orchids

[kavanaru]

Does anyone has Araceae in S/H? just wondering whether Arum or Amorphophallus (the small species of course) would like it... Zantedechia most probably yes...

I found Zantedechia like to be in water logged conditions.
I think for the most part, non semi-aqautic or aquatic Araceae with corms would probably rot. Or maybe not? I have an extra Typhonium vulgaris corm that you have inspired me to try via S/H! If you have extra corms etc... why not give it a try?

[kavanaru]

I have some extra Arum palaestinum and Arum creticum, which I will try in S/H for next year (They are currrently growing well, and do not want to change them this season).

As per Amorphophallus... The corms disappear completelly during the growing season and a hole stay in their place. They need a very stable soil to hold the big leave, while producing a new corms, which should fill in the left hole... Don't think LECA would provide enough support...

On a side note. I have some Arum maculata seeds that I collected late summer. They have not sprouted. Do you have any experience with the seeds? Thanks.

[kavanaru]

Nop! no experience with Arum seeds... my Arum plants are grown from corms...

Ramón, How about using marbles at the bottom of the pot for stability? True, not as absorbent as Prime Agra/Leca but I pet if you get them small enough, you can still get the job of capillary action to bring water up to the top done.

Tin, I assume you were speaking about Amorphophallus and the stability issue I mentionned The problem with Amorphophallus, is that the corm is larger that 25 cm (10 inches) diameter and the leaf is about 2 meters (6.5 feet) tall (I am speaking from Amorphophallus konjac, the one I have in Switzerland )... when the leaf grows and the corm disappears, you end up with a big empty cavity in the ground, surrounded by the roots, which take over the role of supporting this huge green monster. Therefore, if the ground is not stable enough, you end up with a leaf playing "Jack-in-the-box" or, even worst, lying on the floor... This happens once when using a very loose compost based soil (wanted to give the young plant a kick for faster growing ) and almost lost the plant - don't want the stress anymore...

My slogan with plants is "Either they adapt to my conditions or they have to leave!", however I try to give them conditions fair enough for the game... And giving Amorphophallus the right soil, is part of the fair game for me
