  • water dropWater

    For a Geranium, including the Pelargonium 'Captain Starlight', regular watering is key to keeping the plant healthy. Allow the soil to dry out slightly between waterings, which typically means watering once every 1 to 2 weeks, depending on the climate and indoor conditions. When watering, it is recommended to use about 16 ounces of water for a standard 6-inch pot. However, this can vary based on pot size and environmental conditions. Always ensure that excess water can drain freely to prevent waterlogging and root rot.

  • sunLight

    Geraniums thrive in bright, indirect sunlight, making them suitable for east- or west-facing windows where they can receive at least 4 to 6 hours of sunlight daily. Direct afternoon sun might be too harsh and can scorch the leaves, so if you only have a south-facing window, place the plant a few feet away or use a sheer curtain to diffuse the light.

  • thermometerTemperature

    Geraniums prefer moderate temperature conditions, ideally between 65°F and 75°F during the day, and not lower than 50°F at night. They can survive temperatures up to 80°F but should be protected from frost and temperatures below freezing. Keep Geraniums away from drafts and sudden temperature changes to ensure healthy growth.

  • scissorsPruning

    Geraniums benefit from regular pruning to encourage bushier growth and more blooms. Prune in early spring to remove dead or damaged growth and to shape the plant. Deadheading, or removing spent flowers, should be done as needed throughout the blooming season to promote continuous flowering. Cut back the Geranium by about one-third in late summer to prepare it for the next blooming cycle.

    Geranium 'Captain Starlight' should be repotted every 1 to 2 years or when it outgrows its container. Repotting in spring allows the plant to settle before the growing season.

  • circleLife cycle

    The life cycle of the Geranium 'Captain Starlight', starts with seed germination, where the seeds must be sown in a warm, well-drained medium and require light to germinate. The germinated seeds grow into seedlings, which develop true leaves and are gradually acclimatized to outdoor conditions before being transplanted. As vegetative growth progresses, the plant forms a bushy structure with lobed leaves, and flowering stems. The geranium then enters the flowering stage, producing vibrant flowers that can sustain several rounds of blooming given proper care through deadheading and adequate nutrition. After the blooming period, if the flowers are left to pollinate, they will produce seed pods, completing its reproductive cycle. During the fall, geraniums can be cut back and overwintered indoors, or treated as annuals and allowed to complete their life cycle before succumbing to frost.

      Spring-Early Summer

    • Pelargonium 'Captain Starlight', commonly known as Geranium, is most commonly propagated through stem cuttings. This is a simple and effective method that can be carried out in late spring or early summer when the plant is actively growing. To propagate, a healthy, non-flowering stem of about 4 to 6 inches (10 to 15 cm) is cut just below a node. The lower leaves are then removed, and the cut end is dipped in rooting hormone powder to encourage root development. The cutting is then planted in a pot filled with a well-draining potting mix and kept in a warm location with indirect sunlight. The soil is kept slightly moist, and within a few weeks, the cutting should develop roots and can eventually be transitioned to a permanent location.
