May 6, 2019 – Impulse Purchase of a Hoya Cutting

Purchased from ebay.

I made an impulse buy that I am hoping will go well!  I bought a 6 inch cutting of Hoya australis ‘Lisa’ from an ebay seller in Florida.  This cutting is a true cutting, meaning there is no root. 

The plan is to try water propagation, which is where you put a section of the plant in a container of water for a length of time (generally a few weeks to a couple months, depending) while it develops roots (more detailed directions to follow, if you are interested). 

I have rooting hormone in the mail from Amazon as I’ve read that Hoya propagation is typically more successful using hormone. 

I’ve watched video accounts of and read about hoya water propagation online, but seeing it and experiencing it are two different things.  It should be a fantastic learning opportunity regardless of the outcome, which I promise to report to you even if it isn’t positive.

How to Propagate a Hoya Cutting in Water

Now that the cutting has arrived, I am going to prepare it for propagation.

  1. To propagate, the recommendation is to take at least a two-node cutting.

    A node is the place on the vine where the leaves emerge. So a two node cutting would be a piece of vine that had two places where leaves emerged.
  2. The cutting that was sent to me has 3 nodes or three places on the vine where leaves emerge.

    I have to choose one of these places to cut off the leaves.

    The node that I remove the leaves from will be the place where the roots grow and the place where I want the vine to be submerged in water.
Two nodes still have leaves in tact; the node on the left I have removed the leaves from. Hopefully that node will be the birth place of future roots soon!

3. Once I’ve removed leaves from one node, I will fill one of the glass propagation containers with water and add a drop or two of rooting hormone.

Here’s what the cutting looks like currently!

4. Then the last step is simply to add the cutting and wait!

I plan to check the water level daily, in case evaporation causes a need to top off the container. I will also replace the water entirely if it becomes murky. Otherwise, there is nothing that needs to be done!

5. Once the water roots are a few inches in length, the cutting can be potted in soil.

Important note: When transferring to soil, you will want to keep the soil slightly moist for the first week or so to allow the roots to acclimate since they are used to being in water. After that, you can water as normal!

For hoyas, you will want to use a very well-draining soil as almost all hoyas are very succulent in nature, meaning that they retain a lot of water in their thick leaves and do not like to sit in wet soil. I personally use a mixture of peat, perlite, and orchid bark. Yay for new plants!

Keep reading to see how my propagation experience goes! 🙂

May 16, 2019 – Hoya australis ‘Lisa’ has Root Buds and I have Excitement… LOTS OF EXCITEMENT!

It has been exactly one week since the hoya cutting arrived and was placed in water for propagation. I am ecstatic to report that root buds have formed and things are happening!!

 

May 22, 2019 – Growth Updates and a Maybe-Peduncle!?

Another week has shown more root growth at the node and a new location of root growth!

I was under the impression that the roots would grow around the node itself. However, I do know that Hoyas are epiphytic plants, meaning that they grow among trees and other epiphytic plants. This means that they use aerial roots along their vines to secure themselves and climb, so they do not require water or soil to root. Cool, right?

…So maybe I shouldn’t have been that surprised!

I also have been watching one area near a node where I left leaves intact because I have suspected that it may be a peduncle, which is where flowers on hoyas will form. These peduncles will flower over and over again for as long as they are intact. The more I am watching this maybe-peduncle grow, the more I am becoming convinced that it is indeed a peduncle. That is very exciting!!

Hoyas need at least 3 years of maturity before they are able to grow peduncles and flower, so the fact that this cutting has a peduncle means that it came from a healthy, mature plant. That is great news! Here’s some pictures from this week’s update:

August 30th – I skipped a few updates… let me explain!

The differences in the root system week-to-week were too small to provide weekly updates so I waited until there was something worth updating!

The roots are now several inches in length and it is time to transfer the cutting to soil.

I am transferring it to a plastic pot because I want to ensure I do not shock the roots too much since they are used to being in water.

I will check the pot daily to ensure the soil is watered as soon as it begins to dry while the roots acclimate.

After a period of acclimation, I will then water this cutting the way I water all of my hoyas: let the soil dry out completely before watering.

I will also often check to see if the lower leaves are still firm in the more succulent hoyas, like Hoya australis ‘Lisa’. This tells me whether those leaves are still retaining water. If they are, it doesn’t need to be watered! If the leaves have become more pliable, I know its time for a good watering!

October 19, 2019 – Update post-soil transfer

I just wanted to provide a quick update to let anyone who finds this post know that transfer to soil was successful. Here is a picture of my rooted cutting looking beautiful in its pot!

March 18, 2020 – Almost one year later….

My cutting has a huge root ball and has grown several beautiful leaves. You can see that the newest leaves are still pink.

I am now potting it together with another cutting of Hoya australis ‘Lisa’. The photo of them potted up together and trellised is below!
