Light: Bright light to full sun. Give your ivy leaf geranium as much light as you can spring through fall. Move it outdoors for the summer, if you like. Just bring it back inside when the temperature drops below 50°F/10°C. This is a tender perennial that doesn’t like the cold.
Water: Keep soil evenly moist, not soggy. Allow the top 1-inch (2.5 cm) of soil to dry between waterings. Cut back on watering in winter, but don’t allow the soil to dry out completely.
Humidity: Average room (around 40-50% relative humidity). Use a cool-mist room humidifier to increase moisture around the plant.
Temperature: Cool nights (55-60°F/13-16°C) and warm days (65-75°F/18-24°C) will trigger flower buds.
Soil: Peat moss-based soilless mix.
Fertilizer: To get the most blooms, feed every 3 weeks with a high-phosphorus fertilizer only while the ivy geranium is budding and flowering. High-nitrogen fertilizers given to young plants will bring a lot of foliage growth, but few flowers.
Propagation: Take stem cuttings in spring and root in fresh potting mix. Geraniums are easy to grow from seeds, too. Sow seeds in early spring.
