  Help with Anthurium scherzerianum
From: EGoldfluss at aol.com on 2009.05.13 at 01:57:50(19319)
I grow a good number of Anthuriums successfully but this one has me pulling my hair out. Being the stubborn sort I've ordered yet another A. scherzerianum in the hopes that I can keep this one from immediately turning yellow, dropping all is leaves and departing for the great garden in the sky.

Any suggestions for the successful culture of this plant will be greatly appreciated.

Best regards,

Hi Ed,
I grow this one and find it to be an easy one to grow(for me).

I use a potting mix with a lot of #3 and #4 sponge rock(perlite), that's the largest I can find and mix that about 50/50 with a good peat based potting mix. I use Pro-mix, but I'm sure any type of peat based potting mix would work equally well.
I try not to overwater this one, being a Mexico species they do go through some dry spells, so if you tend to water a lot use a smaller pot or an unglazed clay pot so you will get some air exchange at the roots. Also try not to pack the soil when you pot. Keep the soil as light and airy as possible. It will naturally pack down when you water it for the first time.

I would suggest with an plant that is going down hill to un-pot it and check out it's roots. My guess is the roots have rotted away, so check out the base of the stem that is under the soil line. If the stem is soft or rotten you should cut and scrape away any soft tissue until you reach firmness and white-ish 'meat'. I would then treat that with some root-tone, or even cinnamon to prevent the rot from returning. If it is rootless I would suggest potting it in a mix that is 75% large perlite/25% peat mix and placing a plastic bag as a tent over the top to increase the humidity without keeping the soil too wet.
On several occassions I have received cut back stumps of this species from Mexico and have had excellent success getting them to root out with this perlite based mixture. I suggested the tent in case you live in a drier climate than me(Oahu).

Another thing I do with Anthuriums with no roots is to pot them in New Zealand sphagnum moss. I loosly wrap this moisten(wrung out well) moss around the roots area and pot the plant in an unglazed clay pot, remembering 'not' to tightly pack it. Then sleeve the clay pot with another slightly larger empty plastic pot. This will keep the clay pot from drying out too quickly and still allows for good air exchange and humidity.

I hope these suggestions work out for you. It's a beautiful species.
Good Luck!

Dear Ed,


I have had newly purchased Anthurium scherzerianum drop leaves , etc. I have a 40% shadehouse that is open to the rainfall. When this species is overwatered, I find they tend to defoliate. After they defoliate, it takes a long time to renew growth. Many commercial growers here use a mix very different from mine and they also use fungicides, which I do not use. My solution is to pot the plant in a very well draining mix and to control the water as best I can. Sometimes this means under sizing the pot as I have no control over the weather. I may plant these in baskets as they dry out faster. This species also prefers bright but not burning light levels. Right now, this species is in active growth and blooming for me. Another threat here are slugs...which spread pathogens simply by biting the new growth...or they completely devour young plants.

I normally do not fertilize my plants, so someone else can advise you on this matter. I am conducting limited experiments with composted steer manure, but the odor is rather strong at first...not so pleasant if you grow things indoors. I also have an opportunity to gather an invasive seaweed from our bay and I will cooperate with a local fishpond to do composting experiments.

I am not familiar with your growing conditions, nor how your plants are planted, so please understand that these suggestions are from Hawaiian lowland, seasonally wet conditions.

I am not much of a collector of hybrids, but Anthurium wendlingeri X Anthurium scherzerianum, first reported by Dr. Kamemoto, is a spectacular hybrid. It can get four foot long, pendant and broad velvety leaves with a large scarlet spathe and a pig tail spadix that can hangs down a foot in length. I would encourage anyone with both species to re-do this cross, as I have not seen this for years after many Hawaiian collections were destroyed by an Anthurium blight.

I have kept one of these for 3 years now and without luck. Well at least enough luck to keep it happy. It always seems to throw out 3-4 new leaves when I think its reached its end. But it has never grown into anything proper. I've tried soil, sphag, orchid mix, and now it is in semi-hydroponics. At first I thought wow, it likes semi-hydroponics because it was putting on so many new leaves, but eventually the story turned out the same as before. I too am at my wits end.

Dear Ed:

This species has a normal elevationalrange that is quite high, probably typically above 2000 m which makes it adifficult species to cultivate under the best of conditions.

Cut this from Toms revision ....

 'The type of A. scherzerianum was believed to have been collectedin Guatemala; however since that time no other collections have been seenfrom that country. So far the species has been found only in Costa Rica,where it is plentiful, and it is likely that the type was collected there.'

 This species grows very well up on the tablelands in tropical Australia . I grew it in the sub-tropics and was surprised when they struggled and died after I shifted up to the wet tropics . Today I saw a sickly plant in flower at my local garden club meeting , the owner has been growing several of them for many years in the wettest town in Australia !
Even temperature all year round  , a fast draining media , and frequent mild fertilizing seems to be how friends of mine get constant flowers and frequent seed set .

Michael Pascall,

Dear Ed:

I made a mistake and mis-read the species name of this Anthurium. I was referring to A. schlechtendalii in my response.
I also grow A. scherzerianum, and just treat it like the others I have and they seem to do OK.
Even so, anytime a plant is going down I always examine the roots and usually find a problem there.

Next time I go to Costa Rica (and I do every year) I'm going to find the little bugger in the wild and see how it grows. In the meantime I received a very nice seedling grown in bark chips. I'm going to do one in bark and treat a second as a lithophyte. I think drying and air circulation may be the key.
