WaterGeraniums, including the Pelargonium 'Irene Cal', should be watered thoroughly when the top inch of soil feels dry to the touch. Typically, this means watering every 7 to 10 days, but this can vary depending on environmental conditions such as temperature and humidity. Water the plant with approximately 8-16 ounces of water, ensuring that the soil is moistened evenly. Avoid wetting the leaves to prevent disease, and allow the excess water to drain away to prevent root rot. During the winter months, reduce watering to compensate for slower growth.
LightGeraniums prefer bright, indirect sunlight and should be placed in a spot where they can receive at least 4-6 hours of sunlight daily. An east- or west-facing window where they are shielded from the harsh afternoon sun is ideal. Avoid placing your Geranium in full shade as this can lead to leggy growth and fewer blooms.
TemperatureGeraniums thrive in temperatures between 65°F and 75°F during the day, and they prefer cooler temperatures at night, around 55°F to 65°F. Do not expose the plant to temperatures below 30°F as it can be damaged by frost. The Geranium's ideal growing conditions exclude extreme temperatures; both excessive heat above 85°F and cold drafts should be avoided for optimal health.
PruningPruning Geraniums helps to promote bushy growth and remove dead or yellowing leaves and spent blooms to encourage further flowering. Prune the plant lightly throughout the growing season as needed, and more extensively in late winter or early spring to prepare for new growth. The best time for major pruning is just before the plant resumes active growth, which is typically in early spring.
CleaningAs needed
SoilThe best soil mix for Geranium 'Irene Cal' is a well-draining potting mix composed of peat, compost or well-rotted manure, and perlite or sand to improve drainage. A slightly acidic to neutral pH between 5.8 and 7.2 is ideal for this plant.
RepottingGeranium 'Irene Cal' should typically be repotted every two to three years to ensure it has enough room for growth and fresh soil for nutrients.

Life cyclePelargonium 'Irene Cal', commonly known as zonal geranium, begins its life cycle with seed germination, where the seeds sprout and develop into seedlings when exposed to the right temperature and moisture conditions. The next stage is the vegetative growth phase, where the seedlings grow into mature plants with a robust root system, stems, and leaves through photosynthesis and nutrient uptake. Following the vegetative stage, the plant enters the flowering phase, where it produces clusters of flowers that can vary in color, with 'Irene Cal' often showcasing vibrant blooms. After pollination, which can be facilitated by insects or wind, the plant sets seeds within the spent flowers, completing the reproductive cycle. Finally, if conditions become unfavorable, such as in regions with cold winters, the plant may enter a period of dormancy or die back, awaiting favorable conditions to regrow if it is a perennial variety or concluding its life cycle if it is an annual.
PropogationPropogation time
Spring-Early Summer
The most popular method of propagating the Pelargonium 'Irene Cal', commonly known as geranium, is through stem cuttings. This is typically done in late summer to early fall to allow for enough time for the cuttings to establish roots before the growth period in spring. A healthy, non-flowering stem is chosen and cut at a length of 4 to 6 inches (about 10 to 15 centimeters) with a sharp, clean knife or scissors. The lower leaves are removed, leaving two or three leaves at the top. The cut end is often dipped in rooting hormone to encourage root growth and then the cutting is planted in a well-draining potting mix. The cutting should be kept in a bright area with indirect sunlight and the soil should be kept moist but not waterlogged until strong roots have formed, which usually takes a few weeks.
