How to Propagate Prayer Plant: Root Division
Root division involves dividing the plant into smaller sections and repotting them individually. This method is ideal for overgrown plants, especially the Calatheas variety, which require transplanting.
Root division is best done in spring and should be avoided at all costs during winter and fall. However, ensure your mature prayer plant has many stems for this technique, and note that division may make your prayer plant look sparse.
Remove Plant from Pot
You don’t want to damage the plant while removing it from the pot, so take precautions. Do not pull the stems or leaves to remove the plant. Instead, squeeze the sides of the plant pot or run a knife along the pot edges to loosen the roots.
Then, turn the container sideways to pull the plant out gently because the roots might be tightly wound or hooked around the pot base. Hurrying damages the roots. The plants can handle a bit of rough handling, but you don’t want to take the risk.
Tease the Roots
Brush away the soil on the roots lightly so that they are visible. Gently pull apart the coiled roots from the bottom. The more you divide the roots, the easier it will be to identify the sections. Remove the soil simultaneously as you work your way up.
As you continue pulling apart the roots, look out for issues such as fungus or root rot. Cut away any roots that feel slimy, are saturated in moisture, or appear dark-colored rather than yellow or white. This step could take a while if your plant is big, but do it patiently, or your mistakes might affect the next step.
Divide the Roots
If you look closely, you will notice groups of roots connected naturally to groups of stems. These independent root clusters have several strong stems and some leaves, making for independent plants.
Once you identify the sections, separate the plant while keeping a healthy number of roots with each section. You can divide it in half to keep as many leaves with each section as possible or in three if it is large enough. If they are tangled or difficult to separate, sterilize sharp scissors or gardening shears with rubbing alcohol, then cut the roots.
Repot Each Section
Fill as many containers as there are sections with fresh potting mix. The texture of the new mix should be similar to what the plant was in to ensure the plant sections are comfortable in their new home and do not get transplant shock.
Make a hole in the center of the pots and replant your divisions at the same level they were initially in. Do not bury the stems deeply to reduce the risk of root rot. Tamp down the mix around the base and water immediately to help the roots settle in their new home. Do this step quickly to avoid stressing the plants further.
After Care
The sections will thrive if placed in bright, indirect sunlight and receive adequate water in spring and summer to maintain soil moistness. You can reduce watering in fall and winter.
Fertilize your plant every 2 weeks with a balanced, water-soluble fertilizer diluted to half strength by mixing half the instructed amount of fertilizer into a full amount of water. Only fertilize once a month in the fall and winter.
