Fill a 6- to 8-inch growing container with potting mix. The container needs several holes in the bottom to prevent damage from over-watering.
Plant dracaena Janet Craig Cane with its roots buried at their prior depth. Water until the potting mix feels lightly moist to the bottom of the container.
Situate the plant in a location protected from hot and cold drafts as well as direct sunlight.
Water the plant when the surface of the potting mix feels completely dry. Pour off any water that pools in the drainage pan beneath the container promptly to prevent it from being reabsorbed.
Feed monthly during spring and fall with foliage plant fertilizer. Read package instructions to determine exactly how much fertilizer to apply because this may vary between products.
Trim the stems of dracaena Janet Craig Cane back with pruning shears if the leaves begin to drop or the plant outgrows the available space. This stimulates the development of new foliage and keeps growth in check.
