There are many varieties of ornamental ginger. Grown primarily for their flowers, these perennial plants grow best in areas with mild winters and minimal freezing. They can also be grown in pots in areas with colder winters, with the pots moved outdoors during the summer and indoors when the temperatures begin to drop. Ginger plants require minimal maintenance in order to thrive. Caring for your ginger flower plant properly ensures it will bloom for years to come.
Plant flowering ginger in a well-drained bed that receives full to partial sunlight. Work in a 2- to 3-inch layer of compost to add drainage and organic matter to the planting bed.
Water as necessary to keep the soil moist. A single, weekly watering that provides about 1 inch of water to the bed is sufficient in most cases, though extra watering may be necessary if the soil dries out sooner during periods of drought.
Fertilize ginger once a month with a nitrogen-rich fertilizer or a fertilizer formulated for flowering rhizomes and bulbs, following label application instructions. Fertilize potted ginger plants with a water-soluble houseplant fertilizer once a month.
Cut off the flower stalks with pruning shears once the blooms have withered. Snip the stalk off at the base of the plant. Remove any dead or damaged leaves by cutting them off where they emerge from the plant.
Check the undersides of leaves and the stems for aphids and other insect pests. Aphids are usually small clusters of white, yellow or brown insects. Spray the area with water to wash off the bugs. If the infestation is severe, rinse the plants with an insecticidal soap once every one to two days until the infestation is under control.
