Dracaena houseplant varieties D. fragrans and D. deremensis have cultivars that can reach from 6 to 10 feet (2-3 m.), so height control by pruning canes of older plants is useful when growing a dracaena plant. New foliage will sprout just below the cut in a few weeks. Propagate the removed cane for another plant. Dracaena plant care involves keeping the soil of houseplant dracaena moist, but never soggy. Drooping or yellowing leaves indicate over-watering or poor drainage.
