Overwintering Scented Geraniums

Scented geraniums (Pelargonium) are closely related to common geraniums. They feature smaller, less numerous flowers, but the entire plant is fragrant. Scents typically fall into citrus or rose categories.

Containing essential oils, scented geraniums are valued in the cosmetics industry for their cost-effective plant-based fragrance, “Geraniol,” used in lotions, shampoos, and creams. In aromatherapy, their scents are considered mood-lifting. Additionally, their floral-fresh aroma deters mosquitoes, making them suitable for balcony planting.

Care and Propagation

Scented geraniums, native to South Africa, are frost-sensitive. They should not be placed outdoors until after the last risk of frost (mid-May in many regions). They thrive until the first autumn frosts, displaying lush green foliage and pleasant fragrances. Standard potting soil is sufficient, and they prefer a location with partial shade to full sun.

Overwintering or Taking Cuttings?

Frost in late autumn is fatal for scented geraniums. Two main overwintering methods are available:

• Storing the Whole Plant: Place the entire plant in a bright, cool, and frost-free winter location until May. During this dormant period, water sparingly and refrain from fertilizing.
• Propagating from Cuttings: Break off approximately 15 cm long shoots along the leaf axils and place them in room-temperature water. Fine root shoots will appear after about three weeks. Plant these rooted cuttings into pots with soil and keep them slightly moist throughout winter. This method provides strong, robust plants for balcony decoration by May.
