A few years ago I started noticing around Valentine’s Day the heart shaped plants for sale. I got one and with some time, my oh my did it grow! It grew to the point of me constantly having to prop my Hoya Kerrii up because it was top heavy and kept falling over.

Today, I am sharing my tips for how to propagate them because there are never enough plants in this world in my opinion.

Propagating Hoya kerrii

There are two main ways you can cut a hoya kerrii to propagate it. You can take leaf cuttings or you can propagate by stem cuttings. Read below to learn more about each of the methods and see which one will work best for you and your plant.

To propagate Hoya kerrii by leaf cuttings

To propagate Hoya kerrii by a leaf cutting, first pick a leaf with a node on it. A node is that small bump on the stem where leaves eventually grow out of.

Once you find the node, you cut the leaf off the stem right below the node.

Then you can either place the leaf in a jar of water (this is called water propagation) or you can dip it in rooting hormone and place on soil. With either route, you should see roots in about 4 to 6 week’s time.

Once the cutting has rooted, you can remove it from the pot and plant it in a larger pot.

NOTE : When doing leaf cuttings, there is no dormant bud from which new stems can grow. So if you only take leaf cuttings, you will only grow that single leaf. No new stems or leaves will grow.

Propagating Hoya kerrii with a stem cutting, is my preferred method. You simply cut a section of stem that is at least 4″ long and has at least 2 leaves on it.

Remove any leaves that are near the bottom as you don’t want them sitting in water.

Place the lower portion of stem in a jar of water or dip in rooting hormone and then on soil. Keep the soil moist but not soggy.

How to take cuttings from a Hoya Kerrii

To take a cutting from the Hoya kerrii plant start with a clean sharp knife to cut the stem or leaf. You can also use scissors for this task.

Can you propagate Hoya Kerrii in water?

YES! Hoya Kerrii can be propagated from stem or leaf cuttings.  Start by taking the cutting from your plant around 4-6″ in length, this will ensure you have at least one node on the stem.

Remove any leaves on the lower portion of the stem before placing it in a jar. Fill the jar about 3/4 of the way full with water.  Keep the jar in indirect light and watch over the next few weeks as roots start grow.

Once you have the cutting, remove any lower leaves from the cutting so they don’t sit in water.

Keep the cutting in bright indirect sunlight and be patient. Cuttings often take several weeks before starting to grow roots.

Once you have taken a cutting from your plant and placed it in water for a few weeks, you will see those roots start to grow. The longer you leave the cutting in the water, the more roots it will grow.

You can see how many new roots are growing on my cuttings below! Once your roots are at least 2-3″ long, you can transplant into soil.

  1. 4-6 weeks?!? Nope. My cutting with 3 leaves on it has been in spring water now for FOUR MONTHS! There’s lots of little roots, but the longest are barely over an inch long. This plant roots painfully slow!
