Having tried just about every mix and combination of such in the world....I have settled on a real winner that I am very pleased with for my hoyas and ALL of my tropicals: BIG R + #3 Perlite (#2 OK too). I learned this from a good friend who is a very successful grower of tropicals and who was the Head of Propagation at Waimea Botanical Gardens on Oahu. The mix is about half and half.... BIG R is called (on the bag) a soil conditioner and is essentially redwood shavings. The BEAUTY of it is that it costs under 10$ for 3 cubic feet!!! So, here is a photo of the straight mix:

For my hoyas, I add Hydroton, usually heavier Hydroton in the bottom of the pot and the ratio depends upon the hoyas' needs. For Eriostemmas I use none as they like being in soil... and for those that need really alot of air around the roots I put a lot... The Hydroton maintains moisture really really well and as my climate is humid most of the time...it really works well for me. If I use Promix or any Potting Soil, my roots rot immediately.

Interesting soil mix. Can you grow hoyas strictly in s/h?

.... Confused sorry...not familiar with s/h. Semi-hydroponic? I think that you can grow hoyas in anything...it all depends on what works for you.... Hoyas grow from where the seed manages to land on some organic matter, grow roots and grow out. The 'secret' is to find that which makes them happy. I think of hoyas like orchids...both are advanticious growers!!! which means they will grow whereever they are happy!!!!

Be sure it is not 'treated' lumber and not sawdust..but shavings are OK.

Carol, Is this the mix you stared my cuttings in. If so, when they first got here I thought this mix would dry out too quickly in my dry climate but it actually seems to retain moistue pretty well. I'll let you know what I think when we are in the heat o the summer. :)

In the heat of summer I also have to water more often.... The important thing for me is that there be the ability for air around the roots (remember...these grow on trees with their roots exposed, for the most part, to air...

This is what I would do to make it even a better mix: I have been experimenting with mixes, observing the larger pots as I pot UP and taking notes. I think I would use hydroton and the bark mix...maybe some perlite, maybe not depending on how moist the plant needed to be. With hydroton unavailable here, I am having to use GrowStones (I talked about these earlier, somewhere) which are larger than hydroton but MAN O MAN..they retain and wick water amzingly well.

So...again...will put some information together with pictures and start a post...experimenting as we go. Won't get to the store for more GrowStones until Tuesday....

I like your mix too Carol. I did think that it would dry out too fast as well...but it's actually working out nicely for now, in the summer, I will have to water it more often. I am in the middle of playing/changing my mix too...
Thank you for sharing your information.

they make mulch for gardens there along with lots of other things... http://www.bowmanlumber.org/MULCH.html there is their site... it looks like there is nothing added... would mulch be okay to mix or would it be too fine or not fine enough? thanks for taking the time to help me!
enjoy that which god has given us... family, friends... and plants!

Here's a pot 'profile' making its hoya VERY happy. Almost all hydroton. The hydroton really holds the moisture!Thumb of 2013-06-11/AlohaHoya/ebc278

So, Carol, if you use a lot of hydroton in your mix and it holds the moisture...you don't have to water as much? Or if you will over water, the 'extra' water will just drain out of the pot..?

I have to repot plants received in your mix Carol if I want to keep them outside because I was having to water 3 times a day. Our humidity is low (today it's 50%) - with hot/dry winds. Often it's over 100 degrees.

Everything is growing well in semi-hydro Growstones.

When I pot the plant I am sure to 'fill' the empty spaces with the smaller chunks, sometimes removing the very large chunks, depending on the plant.

I am saving all of that valuable soil mix you sent with the hydroton, so I can put it all together in one pot and put a plant in it soon. Thumbs up

They make a small GrowStones which I use.

Yes...people say my mix dries out...but then they use peat which stays soggy and strangles the roots. Oh well...not my kuleana.

A couple of plans that I re-potted in Growstones grow very well. I am very happy...very. No need to water them every day, or even every other day.
