1. The surest method of success: plant vertically in a mix of potting soil and perlite. The length of our canes allows for a minimum of three nodes below, and three nodes above the soil, facilitating both root and leaf growth.
2. For those with 'green thumbs': more nodes can be made to produce growth by planting horizontally—a technique we find less successful, especially if attempted (as is often recommended) in water rather than soil/perlite.
As a note, we have never seen ti propagated from seed. While this may be possible, we would not rely on any method other than growing from cane.
Ti (cordyline fruticosa) once planted grows indefinitely and does great outdoors in the U.S. in Hawai’i & Florida, and in similar climates in Australia, New Zealand, South America, and Southeast Asia, as well as throughout the Pacific Islands. It is often used as an indoor houseplant in other places since it cannot tolerate cold weather. Ti likes moisture, but it can rot if kept too wet.
Once a stick of cane is planted, roots and leaves sprout from nodes that develop both above and below the soil level. After the cane has rooted and grown a bit, if you want to make it bushy, ‘top’it with clippers or a small saw (be sure the cut takes place at least a foot from the ground if nematodes exist in your region); divide the cut cane into 5-7 inch pieces of ‘woody’ cane that each have at least 4 nodes and plant in one of the two ways described above.
The remaining ti in the ground will also sprout new growth, often sending out shoots from multiple nodes. If you choose to cut and propagate ti, the exponential growth can be amazing since the plant produces many nodes a year under good growing conditions. Ti does well in sun or shade, and if planted outdoors in almost any kind of soil. It has well-earned its title, “the King of Tropical Foliage.”
