  • water dropWater

    Shikokianum Geranium prefers consistent moisture, so it should be watered when the top inch of its soil feels dry to the touch. Generally, this equates to watering approximately once a week, but this frequency can vary depending on environmental conditions such as temperature and humidity. Provide about one to two gallons of water to thoroughly soak the soil, ensuring that excess water drains out so the roots are not sitting in water, as this can lead to root rot. During the winter months, reduce watering since the plant's growth slows down, but still keep the soil slightly moist.

  • sunLight

    Shikokianum Geranium thrives in partial shade to full sun conditions. The best spot for this plant is one where it will receive morning sunlight and afternoon shade, or dappled sunlight throughout the day. Protecting the geranium from the intense heat of the midday sun will help to keep the foliage healthy and prevent scorching.

  • thermometerTemperature

    Shikokianum Geranium prefers moderate temperatures and can generally tolerate temperatures between 50°F and 75°F. It can survive short periods of colder temperatures down to about 30°F but should be protected from frost. The ideal temperature range for optimal growth is between 60°F and 70°F.

  • scissorsPruning

    Pruning Shikokianum Geranium is essential to maintain its shape and encourage denser foliage. Prune the plant in late winter or early spring before new growth begins. Remove any dead or damaged leaves and stems as well as any leggy growth to promote healthier, more vigorous growth. Deadheading spent flowers regularly will also encourage further blooming.

  • circleLife cycle

    Geranium shikokianum, commonly known as Shikoku cranesbill, begins its life cycle as a seed that germinates in moist, well-drained soil typically in the spring. The seedlings develop into rosettes of foliage and, given proper conditions of light and moisture, the plant will grow into a mature specimen with distinctive, deeply lobed leaves. The Shikoku cranesbill reaches its flowering stage in late spring to early summer, producing white to pale pink flowers with distinct veining. After pollination, typically by insects, the plant sets seed in a unique, beak-like capsule that gives the plant its common name, cranesbill. Once the seeds have matured, the structure splits and the seeds are dispersed, often by wind or foraging animals. In the fall or at the onset of colder temperatures, the plant may die back, entering a period of dormancy, although in some climates it may retain its foliage year-round.

      Spring to Summer

    • Propogation: Geranium shikokianum, commonly known as Shikoku geranium, is most commonly propagated by division, which is ideally done in spring. To propagate by division, carefully dig up the plant while trying to keep the root ball intact. Using a sharp, clean knife or spade, split the root ball into smaller sections, ensuring that each section has a good portion of roots and some shoots. Replant the divisions at the same depth they were growing before and water them thoroughly. This method stimulates new growth and helps to maintain the health and vigor of the parent plant.
