Himalayan cranesbill 'Gravetye' Geranium himalayense 'Gravetye'

Water

Himalayan Geranium should be watered thoroughly, allowing the top inch of soil to dry out between waterings, which typically means watering once a week. During the growing season, especially in hot, dry climates, you may need to water more frequently, perhaps every few days. It is essential to avoid overwatering as this can lead to root rot. A general guideline is to provide about one gallon of water per plant each time you water, depending on the size of the plant and the conditions. Adjust the amount of water during the cooler months when the plant's growth slows down, reducing watering to every other week or less, depending on the plant's needs and the weather.

Light

Himalayan Geranium thrives best in full sun to partial shade conditions. An ideal spot would offer morning sunlight and afternoon shade, especially in hotter climates to prevent scorching. In cooler climates, they can tolerate and even appreciate more sun throughout the day. Ensure they get at least 4 hours of direct sunlight for optimal growth and flowering.

Temperature

Himalayan Geranium prefers temperatures ranging from 60 to 75 degrees Fahrenheit during active growth. They can tolerate temperatures down to around 20 degrees Fahrenheit but should not be subjected to prolonged periods of freezing weather. During the summer, make sure they're not exposed to prolonged periods above 85 degrees Fahrenheit as this might cause stress to the plant.

Pruning

Himalayan Geranium should be pruned to remove dead or yellowing leaves and to maintain its shape. This is best done after the first flush of flowers has faded which encourages a second bloom. Pruning can be done every few years to rejuvenate older plants, ideally in early spring before new growth begins.

Cleaning

As needed

Soil

Himalayan Geranium thrives in well-draining, fertile soil with a pH range from 5.8 to 6.8. A mix of loamy soil, compost, and a small amount of sand or perlite will create an ideal environment for growth, ensuring proper drainage and nutrient retention.

Repotting

Himalayan Geraniums typically do not need frequent repotting and can be repotted every 2-3 years to refresh the soil and accommodate root growth. It’s best to repot in the spring just before the growing season begins.

Humidity & Misting

Himalayan Geraniums are adaptable to a wide range of humidity levels but prefer average room humidity. Ensure good air circulation around the plant to prevent disease.

Suitable locations

• Indoor

  Place in bright, indirect light and water when topsoil is dry.

• Outdoor

  Plant in part shade to full sun, and ensure soil is well-draining.

• Hardiness zone

  5-8 USDA

Life cycle

Geranium himalayense 'Gravetye', commonly known as the Himalayan Cranesbill, begins its life cycle as a seed, which after a period of dormancy, typically requires a combination of warmth and moisture to germinate in the spring. Once germinated, it develops a rosette of basal leaves and a deep taproot, which prepares the plant for its vegetative growth phase. During this phase, the plant undergoes rapid leaf and stem development, eventually forming a mound of foliage. The Himalayan Cranesbill enters its reproductive phase in late spring to early summer, producing numerous violet-blue flowers that attract pollinators for seed production. After flowering, seed development and dispersal occur, allowing for the potential colonization of new areas. The plant may die back to the ground in winter, especially in colder climates, only to regrow from its hardy rootstock with the return of warmer temperatures in spring.

  Spring to Summer

• Geranium himalayense 'Gravetye', commonly known as the Himalayan geranium, is most commonly propagated through division, which is ideally undertaken in spring or autumn. This involves digging up an established clump and carefully separating it into smaller sections, each with a good portion of roots and shoots. Divisions should be replanted at the same depth they were originally growing and watered in well. This method ensures a quick establishment as it allows for mature plants to spread efficiently and maintain the genetic identity of the cultivar, resulting in a garden display that is consistent with the parent's characteristics. It is the preferred method for many gardeners due to its simplicity and effectiveness.
