Diane, it looks like it is doing well. I would never attempt to tell you what to do, just to share what is happening for me, and let you decide if it applies to what is happening for you!

Recently I've noticed a whole BURST of growth on mine. Mainly since the weather cooled abit. I've also been seeing yellow leaves, and in some numbers that were starting to alarm me. But, I've got a lot of growth, and much of it happening this year. (The pink is a begonia hanging next to)

What I determined, was all the leaves that were yellowing, were pretty far inside of the layers of the plant, meaning they were older leaves. I just kept plucking them out, and moving on. I was a bit stressed with all this growth, but No Buds or blooms. But then, I saw a bunch of umbles fattening up, and popping out.
You can see here, a yellow leaf, deep inside of the layers of growth.

So, my interpretation of what is happening to you would be that your plant is loosing older leaves, but refreshing with a burst of new growth, and things are as they should be in the world. Since you are showing Lots of new growth, the plant is happy. At least, that is the way I would look at it.

Keep an eye on the rest of the leaves, if they look like they are drying out or collapsing with wrinkled tissue, I would worry then.

Nice Macro shots, by the way.

Thanks Cena!

Your Australis is looking great despite the yellow leaves:-)

I think you are right as to them being older leaves going, but on a small plant like mine I'm maybe a tad more concerned. Hey! Maybe those new growths are umbrels (umbles?) too! Doubt it but one can only hope.

Thanks again for the nice comments on my photos too! It's fun playing with a digital camera.

FYI, this is pretty funny..... couldn't resist posting this info:-)

Proper spelling is Umbels: noun, type of flower cluster.

Umbrel: no such word. (oops)

Umbles: noun, the entrails of a deer.

Lol! Boy oh boy things sure get messed up by mixing up the 'e' and 'l'

Diane,
That is very funny, now I may never be able to use that word again without sniggering. It would nice if it WAS umbrels; like an umbrella of little flowers!

Diane, don't change a thing it looks to me like your plant is happy and perfect, my australis drops leaves if it needs to "go higher" and will later add leaves or branches as it sees fit. I have found that the growth of hoyas is in spurts, either climbing, branching or leafing out but rarely does any two of these at the same time. Even when one branch starts to grow, any branch already growing stops, my experience for what it's worth.

PS thanks for the spelling tip on umbels, I have had it wrong for years, but that's not new for me, I have had a lot wrong for years............

Thanks Leon,

I think it is doing what comes naturally:-)

My Hoya kids are keeping me on my toes this fall!

Well, see, I type faster than I spell. I am doomed if I want to type the word 'plan', it always comes out plant. I've gotten kind of used to an EDIT button, also.

And I don't care How Long you look at a post, if you wrote it, you will see it as you 'wanted' it to read. Not the glaring spelling errors, or that weird word you left in the middle of the stream when you changed subject directions and headed south instead of north...
