Anthurium, Schefflera and Pachira... Can't find an exact answer!

joeturbo26October 11, 2011

Hello fellow horticults members! I just joined the forum today, however, have been reading posts for a long time!

I write today because I am searching for an answer and detailed method if at all possible.

I know my question has been touched upon in other posts with brevity, but I'd like the facts if possible!

I've been growing Anthurium, Shefflera (both in bonsai and regular) and Pachira for quite some time. I've always admired those Hawaiian Lava Plantings where the plant is grown in Lava rock as a medium. I recently converted an extra bedroom in my apartment into an indoor greenhouse, affording me the space to try some new things!

I've got lava rock, plants that are ready for propagation and various other supplies.


I inspected one close up at my local bonsai nursery (bonsai boy), seemed to be some floral oasis in which the plants roots which is then inserted into the rock?

Anyone have the know how or opinion to share?

Are you talking about growing in very large lava rock/s?

I use small lava rock (Scoria) as a planting medium all the time. In fact, my Pachira
is in a mix of lava rock, perlite, and bark. There might be some pumice, too.

You need to make sure that moisture and nutrients are provided.

Thanks Josh! Yes I meant very large lava rock though. Take a look at the link.

Here is a link that might be useful:

the plant in the picture was rooted in a depression in the rock. The rock was partially submerged in a weak nutrient solution with the rock wicking sufficient water & nutrients to keep the plant happy, or grown under very high humidity with the rock being spritzed regularly with water & nutrient solution. Either method provides a favorable environment for the development of healthy roots - requisite for healthy plants.

This planting is similar, though there is a very small amount of soil in the very small depressions in the rock:

It gets watered with a contact lens solution bottle filled with distilled water or nutrient solution, depending on the plant's needs.

Al, that looks amazing! Did you grow that yourself? Oh no! I feel a new obsession coming on!

Yes, I planted it & maintained it until it outgrew the rock after 2-3 years. It's a piece of lava my brother brought back from Hawaii. There are several succulents, Carissa, and Hedera (ivy) all mixed in on the same rock, and many are plants you wouldn't normally find growing side by side ..... 7 or 8 different plants if you look closely.

Some are in tiny pockets of soil & others are simply stuck into very small holes in the rock. I put the whole planting in a 10 gallon aquarium I often use as a propagation chamber, with a glass cover and a double 24" bulb fluorescent fixture for light. The aquarium was slightly vented so humidity was high but there was still some air flow, & I misted only the rock daily or twice daily until roots had grown into the rock pores to the extent they would support the plants.

Joe, glad you broahed this subject. In 2010, I got an Anthurium but it's growing in wood, not lava rock. I don't know its proper care.

The instructions said to mist, but I wonder if spraying is enough moisture. No mention fertilizing.
Or, what to do when roots take over.

Here's an older pic of needs work.

Hope you get an answer on care, etc. Toni

The next two are the same plant, a snapdragon before & after pruning. Thanks for the kind words, btw. Plants that don't lend themselves to being instilled with a personality just don't interest me much. In order for me to want to grow something in a pot, it has to be something I can manipulate into something attractive or unusual.

Take care.

Al, would should compare notes! I love your style! I actually did my best at starting a schefflera and a anthurium in lava. Going to take pictures right now and post them in another followup here.
