Propagating Cuttings

Keaau, HI(Zone 11)

I was cleaning out my photo files this morning, and found some pics I thought would be useful for some who have questions about rooting cuttings....

This first one show aerial rootlets...where the roots will come from. Not all hoyas display the aerial rootlets, When there are rootlets along the stem, it is not so critical to get the bottom of the node in the soil.

Here is a cross section of a hoya to be started. Often growth will come from the buried node as well as the top node and is one of the advantages to making 2 node cuttings.

Now a smaller hoya with multiple nodes...

For the very very tiny ones, particularly Dischidia, I lay them ON damp spagnum moss and anchor the vine with an old fashioned hairpin.

Of course, these 'methods' are not cast in concrete, but just how I do it and have success.

Great reference, Carol. Thanks for the valuable info. I will definitely bookmark the thread for future use. Thanks. :D

Carol,
Does your potting mix for rooting cuttings differ from the one you use for rooted plants? If so, what is your 'recipe' for the mix?

Also, do you keep the mix slightly moist or really moist for the cuttings you are rooting?

Shirley...sometimes I use my regular potting mix if I haven't mixed fertilizer in it, to start my plants. The fleshy stemmed ones like it more I think. I use about 50/50 peat/perlite when I change to the finer stuff. I always have the regular mix handy and use the lighter one when I have a lot to do!

I keep whichever mix damp, not soggy. In the winter when the temps get down below 75deg. I use bottom heat.

Oh that's what I did wrong, I have to cut my propagation pots in half :), just kidding.
Good info Carol it is sticky to top material.

Thanks Carol.
I was unsure of how to propagate them. Your pictures and information has made it very clear.

Thanks for the info on propagating hoyas. I cant wait to give it a try. The pictures are a big help. I will have to take a look at your web site. I love hoyas, they are just really hard to find in Houston.

Thanks Again

Where is the best place to take a cutting? Can you root a stem that has aerial rootlets but no leaves?

Hey Tami, I have not had much luck with rooting leafless cuttings. On the other hand, if you can get a cutting with a couple nodes and leaves, plus the aerial roots, you are way ahead in the rooting game. One node and a leaf will do for rooting, however, I like to root 3 or 4 node, semi-ripe wood cuttings. Just try to plant your cutting so a node is below the soil line unless you have aerial roots.

Prescott, AZ

Thanks Mel, I have lots of stems with the aerial roots on them, wanted to give them a hair cut and maybe root, but doesn't sound like that is going to work. Where on the mother plant should you make your cuttings? Right at the leaves or between 2 sets of nodes? Could never figure that one out.
Thanks

Tami, I cut about a half inch above the leaf node. It is going to dry up regardless of where you cut, so, I am not sure that it matters how much stem you leave above the node.

Prescott, AZ

Thanks Mel, just wanted to be sure what was best for the mother plant. I just didn't know that it dried up and fell off. Thanks for the info.

Tami, thanks for finding that thread. I usually bury the node, or leave the bottom of it at soil level...and with the heat and humidity, I can root cuttings with aerial rootlets and not worry about a node. Most hoyas will root from the little nubs along the stem...except Eriostemmas which really need a node.

When I cut a cutting, I take it off about 2" below the node on the cutting...the mother plant will not suffer and you can always clip off anything dead on her.

This is great information. I was wondering if the node that you put below the surface of the soil can have leaves or should you take the bottom pair of leaves off a cutting?

Sandy

Keaau, HI(Zone 11)

I take off the bottom leaves that are pushed into the soil only if it will help stabilize the plant in the pot.

If I am rooting large leafed cuttings, often I make one node cuts and cut the leaves at the node in half. In the beginning, before the plant starts putting out roots, large leaves have a huge area to transpire moisture and they aren't taking any in (no roots to process it)...and cutting them in half lessens the loss of moisture.

Thanks for all these tips everyone!!

Thanks for that information Carol.

Here's a tip from Lesli (another hoya grower) that I decided to try and it worked well.
She likes to root in dark color bottles so a few weeks ago there was a sale on the root beer in the dark bottles (can't remember the name right now they look like old timey bottles) so I bought them just for the purpose of rooting. So I can report that I have some root quickly using this method in water inside one of the mini greenhouses.

Anybody, please...this is not the first time that I have read of preferred rooting in opaque or dark colored containers. So ....why the difference? Why would it matter?

(Zone 1)

I've never heard that so I am curious also as too why something would root faster in dark colored bottles. Just googled and found this: http://www.motherearthnews.com/Organic-Gardening/2008-04-01/Easy-Plant-Propagation.aspx down at the bottom of the page, it says something about dark colored glass absorbs and reatains heat while shielding the roots from light.
