I'm a bit perplexed on how to feed my R. gorgonias. I don't have assassin bugs so that isn't an option. Apparently the sticky substance on these plants is resinous and so it can't absorb nutrients directly from dead insects it has caught. I also read in "Savage Garden" that the author's plant lost most of it's leaves after he fed it with a foliar spray. Up until now I have been spraying my plant about once a month with a 1/2 strength foliar application of Epiphyte's Delight. My plant does have a lot less leaves (compared to the summer time) and I'm beginning to wonder if this could be a result of foliar feeding? What do all of you owner's out there with the pristine plants suggest?  |

I have no experience with Roridula, but if the plant is known to react badly to foliar feeding then you should stop.

On the one hand, Roridula would probably be able to make good use of foliar feed being predisposed to absorbing (Pameridea derived) nutrients through the leaves. On the other hand, the plant can be susceptible to fungal attack which wetting of the foliage on a regular basis would not help. Feeding them may also encourage softer, weaker growth more susceptible to fungal attack. The plants seem to grow OK without the bugs, so on balance I would not risk it, especially if there is evidence that it can be harmful.

What about some osmocate as the plant is a non carnivorous?

We regularly feed our Roridula a foliar spray of 1/4 strength Grow More Orchid fertilizer. We are using the formula for Phalaenopsis orchids (green) which is urea-free. They get a spray about once every two weeks. We have both Roridula gorgonias and R. dentata. We've never noticed any problems. Both are growing well, especially the Dentata. It's quite possible that a fertilizer with urea could cause problems, and I know that Maxsea has urea in it, and it's the darling of so many cp growers right now.
Do you have a photo of your plant?

Hi Jeff - Good tip, thanks! I'm always looking for ways to grow my Roridula better. I'll look into this.
Edit: On quick look, there are a number of Grow More Orchid fertilizer mixes. Which do you use? Any reason for that one in particular? Thanks again!

I forgot to reply to this. I spoke to Peter D'Amato as he's the pioneer for Maxsea in this hobby. He says he fertilises his Roridulas once a month with it.

Hi Richard - Thanks for the update! I can't speak to the concerns others have voiced about the presence or absence of urea, but I do think there is quite a bit of phosphorus in the Maxsea fertilizers I can find. Even with orchids we are learning that we've been dumping in far more P on plants than they can use. Many plants tend to recycle this element fairly well also, so with CP's I do worry about accumulation toxing them out. Obviously Peter has had success, so it's not lethal. Still, I wonder about comparative performance? I'll have to get a few more vliëebos plants to try a little experiment. :-)
