Pruning

Water
The Rozanne Geranium, commonly known as the Hardy Geranium or Cranesbill, should be watered deeply once a week during the growing season, allowing the soil to dry out between waterings. In hotter climates or during dry spells, you may need to water twice a week. When watering, use roughly one gallon of water per plant, ensuring you moisten the soil thoroughly at the root level. During the winter months or in cooler climates, reduce watering to every other week or less, depending on the soil moisture level.
Light
Rozanne Geranium, also known as Hardy Geranium, thrives in full sun to partial shade. The best spot for this plant would be an area that receives at least six hours of sunlight daily, although it can tolerate some afternoon shade. Avoid deep shade as it will inhibit flowering and can lead to leggy growth.
Temperature
Hardy Geraniums, including the Rozanne variety, perform well in a wide range of temperatures, from as low as 20 degrees Fahrenheit to as high as 80 degrees Fahrenheit. They prefer a moderate climate with temperatures consistently between 65 and 75 degrees Fahrenheit for optimal growth.
Pruning
Pruning the Rozanne Geranium, or Hardy Geranium, encourages bushier growth and more blooms. Deadhead spent flowers regularly to prolong flowering. In late autumn or early spring, cut back the entire plant to a few inches above the ground to promote fresh, healthy growth. The best time for major pruning is in early spring before new growth begins.
Cleaning
As needed
Soil
The Rozanne Geranium thrives in well-draining soil enriched with organic matter. A mixture of two parts garden soil, one part peat moss or coconut coir, and one part perlite or sand provides an ideal growing medium. Adjust the pH to a slightly acidic to neutral range, around 5.8 to 7.0, for optimal growth.
Repotting
Rozanne Geraniums typically do not need to be repotted frequently; every 2 to 3 years is sufficient. Check for signs of the plant outgrowing its pot, such as roots circling the bottom or emerging from the drainage holes, and repot in early spring if necessary.
Humidity & Misting
Rozanne Geraniums are adaptable to a range of humidity levels but prefer moderate humidity. Excessive humidity can lead to fungal diseases, so ensuring good air circulation around the plant is key. Average room humidity is suitable for indoor cultivation.
Suitable locations
- Indoor
  Provide bright, indirect light and well-draining soil.
- Outdoor
  Plant in partial sun, fertile soil, and prune to encourage bushiness.
- Hardiness zone
  5-8 USDA
Life cycle
The Geranium Rozanne, also known as the Cranesbill 'Rozanne', begins its life as a seed, which when sown, germinates to produce a small seedling. These seedlings grow into vegetative plants, characterized by their lush, mound-shaped foliage and, eventually, stems elongate, and flower buds develop. The plant reaches full bloom in late spring to early summer, showcasing striking blue-violet flowers with white centers that repeatedly bloom until the first frost of fall. As a perennial, after the blooming period, the above-ground growth dies back, and the plant enters a dormant phase during winter. In the subsequent spring, the plant re-emerges from its rootstock to begin a new growth cycle. The Geranium Rozanne can also be propagated by division, wherein sections of the root system are split and replanted to start new plants.
Propogation
- Propogation time
  Spring to Summer
- Geranium Rozanne, also known as Rozanne Cranesbill, can be most effectively propagated through division, which is recommended to be done in the early spring or fall. To propagate by division, gently lift the entire plant from the ground using a garden fork, ensuring a large amount of root and soil is kept intact with the clump. Next, using a sharp knife or spade, slice through the root ball to create several smaller sections, each with a fair amount of roots and shoots. These sections can then be replanted at the same depth they were originally growing at, spaced approximately 12 inches (about 30 centimeters) apart to allow room for growth. Water the newly planted divisions thoroughly to help establish them in their new locations. This method stimulates rejuvenation of the parent plant while increasing the number of plants in your garden.
