To remove the calamansi seeds without cutting through them, cut through the top 1/3 of the fruit rather than the center. Use the seeds right away after removing the outer layer. They still need to be moist to grow. If you bought the seeds rather than removed them from a plant, they probably have the outer layer removed already.
Alternatively, you can place the seeds directly into damp potting soil, just deep enough to be completely covered by the soil.
If you put the seeds directly into the soil, cover the pot with plastic wrap to create a warm, humid environment.
For seeds planted in a pot, remove the plastic wrap once the seeds have sprouted. You may need to wait an extra day or two for the seeds to sprout.
Always water seedlings thoroughly, so that the potting soil is damp all the way through, when you transplant them to a new pot. Young plants need more water to grow than mature plants.
The seedling should be planted around 2 inches (5. 1 cm) deep in the soil.
Use soil that drains well for calamansi, as this plant doesn’t like having damp roots. If you can’t expose your calamansi plant to full sun, you can use grow lights indoors.
In the US, acceptable regions to grow calamansi outside include parts of California, Texas, Florida, and Hawaii.
If you can find it, coconut coir makes an ideal rooting soil.
The best time to take a cutting is in spring or early summer.
The bottom of the branch is the side where you made the cut.
You can also add some fertilizer rich in nitrogen or liquid rooting hormones at this point. Rooting hormones are available at gardening stores and help stimulate root growth in plant cuttings.
Try misting the cutting every 1-2 days and covering it with a plastic container to maintain a humid environment.
Whenever you move a calamansi plant to a new pot, make sure to water it well.
Only move your calamansi outside if you live in a tropical location. If you are in an area that doesn’t get a lot of rain, water your newly transplanted cutting every time the soil dries out completely until it is fully grown. Don’t add fertilizer right away. Wait 3-4 months, and fertilize 4 times a year.
