WaterHardy Geraniums like the Geranium tuberosum should be watered deeply once a week during the growing season, allowing the soil to dry out between watering sessions. The amount of water required can vary based on climate and soil types, but generally, a good soaking could mean about one gallon per plant each time you water. During peak summer heat or in particularly dry climates, you may need to increase the frequency to twice a week. It is important to reduce the watering frequency during the dormant season to prevent root rot.
LightThe Hardy Geranium thrives in full sun to partial shade. It should be placed in a location where it will receive at least 6 hours of sunlight each day, though it can tolerate some light dappled shade, especially during the hottest part of the day. Avoid deep shade, as this will result in fewer flowers and weaker growth.
TemperatureHardy Geraniums are tolerant of a wide range of temperatures but grow best when daytime temperatures are between 60°F and 75°F. They can survive minimum temperatures down to approximately 20°F, though frost can damage foliage. The ideal growing conditions for Geranium tuberosum generally include ensuring the temperature does not fall below freezing for extended periods.
PruningPruning Hardy Geraniums is mainly done to remove spent flowers and encourage a second flush of blooms. Deadheading, or the removal of old flower heads, should be done regularly throughout the blooming season. Additionally, some gardeners perform a more extensive cut back, reducing the plant by one-third to one-half after the initial wave of flowering to rejuvenate the foliage.
CleaningAs needed
SoilGeranium tuberosum, commonly known as tuberous geranium, requires well-draining soil with a pH of 6.0 to 7.0. A mix containing loam, peat, and sharp sand is ideal for providing the necessary drainage and nutrients. Ensure organic matter like compost is incorporated to enrich the soil and promote healthy growth.
RepottingTuberous geranium should be repotted every 2-3 years to replenish soil nutrients and accommodate growth. It's best to repot in the spring before new growth begins.
Humidity & MistingTuberous geranium prefers moderate humidity levels but is adaptable to various conditions as long as it's not overly dry or wet. Aim for humidity levels between 40-60% for optimal growth.
Suitable locationsIndoor
For indoor growth, bright indirect light and good air circulation is key.
Outdoor
Plant in partial shade, well-draining soil, and shelter from strong winds.

Life cycleGeranium tuberosum, commonly known as the tuberous geranium, initially begins its life cycle as a dormant tuber, typically during the winter months. As the temperature rises in spring, the tuber sprouts and develops into a low-lying herbaceous plant, producing stems and leaves. The plant then enters a reproductive phase where it generates purple, pink, or white flowers with veined petals from late spring to early summer, facilitating pollination by insects. After pollination, the flowers develop into distinctive beaked seed capsules that can project seeds some distance upon dehiscence. As summer progresses, the above-ground foliage dies back, and the plant retreats to its tuberous state, entering a period of dormancy to survive the hot and dry conditions or the cold winter. Each year, the cycle is renewed with the tuber sprouting again in the next suitable growing season.
PropogationPropogation time
Spring-summer
Propogation: Geranium tuberosum, commonly known as tuberous geranium, is generally propagated by dividing its tubers. The best time to do this is in late summer to early fall, after the foliage has died back. At this time, the tuber has stored enough energy to establish itself when replanted. To propagate, carefully lift the parent plant from the ground and gently separate the tubers by hand, ensuring that each division has at least one growth point or 'eye'. These divisions can then be replanted at a depth of about 2 to 3 inches (5 to 7.5 centimeters), spaced approximately 6 inches (15 centimeters) apart, in well-draining soil with ample sunlight. This method allows for a high success rate and a relatively quick increase in the number of plants.
