- Water
Geranium 'Cardinalis' prefers to be watered thoroughly, allowing the top inch of soil to dry out before the next watering. During active growth, particularly in the spring and summer, this may mean watering once or twice a week, especially in hotter climates. Aim to water with 1 to 2 gallons per week during peak summer heat, reducing the amount as growth slows in fall and winter. Avoid getting water on the leaves to prevent fungal diseases, and ensure that the plant has well-draining soil to prevent root rot.
- Light
Geranium 'Cardinalis' thrives in bright, indirect light, but can also handle a few hours of direct sunlight daily. Ideally, place the plant near an east or south-facing window where it receives morning or late afternoon sun. Avoid locations with harsh midday sun which can scorch the leaves, and consider providing light shade during the hottest part of the day in particularly sunny climates.
- Temperature
Geranium 'Cardinalis' can tolerate a temperature range from about 55 to 75°F for optimal growth. They can survive brief periods outside this range, down to about 33°F and up to around 90°F, but these extremes should be avoided if possible. Consistent temperatures within this ideal range will promote healthy, vigorous growth.
- Pruning
Pruning Geranium 'Cardinalis' helps maintain its shape, encourages bushier growth, and removes spent blooms to promote further flowering. Prune lightly throughout the growing season to deadhead and remove yellowing leaves. A more thorough pruning can be done in early spring, cutting back up to one-third of the plant to stimulate new growth and improve air circulation.
- Cleaning
As needed
- Soil
Geraniums, such as Pelargonium 'Cardinalis', thrive in well-draining, fertile soil with a pH range between 6.0 and 7.0. A good soil mix for geraniums is one part peat moss, one part perlite, and one part potting soil. This mix ensures proper drainage and aeration for healthy root growth.
- Repotting
Geraniums should be repotted every one to two years to refresh the soil and accommodate root growth. Pelargonium 'Cardinalis' should be repotted in the spring before the onset of the active growing season for best results.
- Humidity & Misting
Geraniums prefer moderate humidity levels. Excessive humidity can lead to fungal diseases in Pelargonium 'Cardinalis'. Ensure good air circulation around the plant to maintain optimal health.
- Suitable locations
Indoor
Place in bright light, well-drained soil, avoid overwatering.
Outdoor
Full to partial sun, well-draining soil, water sparingly.
Hardiness zone
10-11 USDA
- Life cycle
Pelargonium 'Cardinalis', commonly known as geranium, begins its life cycle when seeds are sown in a well-draining soil mix, with temperatures around 70°F (21°C) being ideal for germination. After germination, the seedlings develop true leaves and are eventually transplanted into individual pots or garden beds, where they enter a vegetative growth stage, forming a bushy structure with lobed leaves. The plant soon reaches maturity and starts to produce distinctive flowers, which can be red, pink, purple, or white, depending on the variety, marking the reproductive stage. Flowers are followed by the formation of seed capsules that, once dried, will release seeds upon disturbance to complete the cycle. Geraniums can also be propagated vegetatively through cuttings, bypassing the seed stage and accelerating the growth process. Throughout its lifecycle, the geranium requires consistent watering, plenty of sunlight, and periodic pruning to encourage bushy growth and ample flowering.
- Propogation
Propogation time
Spring-Early Summer
Propogation: Pelargonium 'Cardinalis', commonly known as Geranium 'Cardinal', can be easily propagated by cuttings. The best time to take stem cuttings for geraniums is late summer to early fall. The process involves cutting a 3 to 5-inch long stem from a healthy parent plant using a sharp, clean cutting tool. This stem should have several leaves but the lower leaves should be removed. The cutting is then dipped into a rooting hormone powder to encourage root development and planted in a pot with well-draining soil mix. It's important to keep the soil consistently moist but not waterlogged and to place the pot in a location with bright, indirect light until roots have established, usually in a few weeks. Once the cuttings have rooted and show signs of growth, they can be transplanted into individual pots or into the garden.
