Lay them length wise in the soil about half way onto the cane. The sprouts of leaves will soon start to appear. If you plant the canes upright, you will only have one sprout of leaves. So planting the cane lengthwise it will produce several sprouts of leaves. Keep the soil moist at all times and do not put young plants into the direct sunlight.
Older plants can tolerate the sun much better.
Remember to watch for the spider mites. They also like the tender ti leaves. The Ti-Plant is known for many things in the tropics. That would be a nice additon for your plant collection.
