Yes, you can grow syngoniums from cuttings. Growing a plant from cuttings is typically how one would propagate syngoniums (also known as arrowhead plants). If propagated correctly, it will eventually grow a new root system, turning into its own little plant.
Where do you cut Syngoniums for propagation?
All plants need to have a node on the cutting to be successfully propagated, and syngoniums are no different. You need to cut below a node for syngonium propagation.
Nodes are the growth points on plants—where new roots, stems, leaves, and aerial roots grow out of. To ensure you’re cutting “below” a node, make sure the stem is pointed to the ceiling, find a node (they often look like bumps along the stem), and cut just below it.
You should now have that node on the part you cut off the plant. This “activates” that growth point, and the node will eventually push out new roots.
Pruning follows almost exactly the same process but with one crucial difference. Learn how to prune syngoniums to keep them bushy.
How to propagate syngonium cuttings
Now that you’ve got your cutting with a node on it, you can choose water propagation or soil propagation. Both work well but I personally prefer water propagation because I like to see the roots grow!
Water propagation: Place the cuttings in a jar of water, making sure at least one node is under the surface so it can grow roots. Place the jar in bright, indirect light and refill the water as needed.
After a few weeks or so, your plant should have roots that are two to three inches long. You can plant the new syngonium into a small pot, or leave it in water to grow there permanently.
Soil propagation: Plant the cuttings into a small pot with lightly moist potting mix. You can also use sphagnum moss as an alternative—either will work. Make sure the node is buried so it can grow roots.
Place the pot in an area that receives bright, indirect light, and just keep the soil lightly moist as the roots are developing. You don’t need to full-on water the plant at this point.
After a few weeks, you can test the cutting by giving it a gentle tug. If there is resistance, the roots have developed and you can start to care for it like a normal arrowhead plant.
How do you divide arrowhead plants?
If you have a large arrowhead plant, division is the fastest way to propagate it. To divide the plant, gently remove it from the pot, then carefully separate the root ball into multiple plants.
You might want to just separate it into two smaller, evenly sized plants, or you might want to separate it into a bunch of baby plants. By gently searching around the root ball, you’ll be able to divide the root systems.
Some root breakage is inevitable, but be as careful as you can so as to not shock the plants too much. Once you’ve divided your plant, pot up each one into appropriately sized pots, and continue with normal care.
