Re: Anthurium Splendidum Cultivation

---

I had been pondering airflow as well! When I first had it in the terrarium over winter, I was only opening it to water it, every week or so. However, that was when that one healthy leaf popped out. The dark dying margins only began very recently. Is there such thing as too much airflow? 

You may be right about it having too much water sitting on the leaves; I had not thought of the consequences of that. I will most likely put a small fan inside and open it up more often. 

Thank you for your advice!

Hiyer, Mads!

What kind of air movement is it getting? It is really vital that there is air movement and a complete exchange of the air in the terrarium every hour or so. The dark leaf margins tells me that that it may be suffering from too much CO2, or too much water.

Just  a thought.

Happy days,

Christopher

Hello everyone, I'm sorry that this will be a novella of a post, but I have just joined this forum and am very curious:

I received a leafless Anthurium Splendidum (W.Bull ex Rodigas as far as I can see, will attach photographs of mine) last autumn. I have been growing it in sphagnum moss in a small closed terrarium at 99% humidity in various experimental temperatures ranging from 62-73F. I have not fed it with anything other than a diluted kelp feed yet, but I have some MSU fertilizer coming in the mail soon to try. It grows with a dim grow light on for 8 hours a day. In the nearly 6 months that it has been in my care, it has only put out a single leaf.

Over the winter it did survive in simple room temperatures, staying between 68-73 F. During this time, it put out it's only leaf. As the weather warmed up, I started doing more research on this anthurium because I was told it would "melt" in temperatures above 75F. I found that many cloud forest species apparently need a drop in temperature at night to slow their metabolism (Steve Lucas mentions it very briefly in his article on Rugulosum, along with many hobbyist growers). by stupid oversight, I did not register that Splendidum is found at a much lower elevation and dropped the nightly temperature to 59F, which after only a single night, caused the effects you can see in the damaged leaf photographs. I NOW know that Splendidum is found in the Tropical Wet Forest to Premontane (T-wF/P) life zone and am wondering if plants in this zone experience any significant temperature drops at night.

 

I have found nothing of this plant's feeding requirements yet, but will most likely try a small amount of Michigan State University fertilizer unless I am told otherwise.

I have seen a single proposition from a hobbyist article that this plant is more sensitive to water quality, but I have not found any other mention. I have several Goeppertias (previously Calathea) that will tell you loud and clear that they don't like tap water, but I have seen no such signs on the Splendidum as of yet.

The things that I am most curious about are:

1) does Splendidum need any temperature drop at night to thrive

2) what and how much should I feed it, as it is in sphagnum moss with no intrinsic nutrients

3) what can I do to make it happier? As a hobbyist, I know that some plants respond well to being given something to climb, or water for their aerial roots, or foliar fertilizers. These are things that are not necessary for sustaining the plant's life but (at risk of anthropomorphizing too much) act as enrichment and lead to larger, healthier plants. I know that Splendidum has no use for any of these examples, but does anyone know of some way I can make its habitat better suited for it? maybe a small water feature for moisture or similar?

I will be eternally grateful for any cultivation tips or other facts about this species!

I am honoured to be speaking with this group of brilliant people and look forward to hearing what everyone has to say.
