Fertilizer: This plant requires regular fertilization during the growing season to maintain optimal growth. A balanced fertilizer that contains equal amounts of nitrogen, phosphorus, and potassium can be used every two weeks. The frequency of fertilization can be reduced to once a month during winter, when the plant is in a dormant stage.
