Watering. Water regularly but allow the soil to dry out slightly between waterings. Avoid waterlogging to prevent root rot.
Fertilizing. Apply a balanced, all-purpose fertilizer once a month during the growing season to encourage healthy growth and abundant flowers. Avoid over-fertilizing, which can lead to excessive foliage with fewer blooms.
