Appearance
Geraniaceae plants have a wide range of appearances, but they share some common characteristics. They have palmate or pinnate leaves and five-petaled flowers. The flowers are usually pink, purple, white, or red, and they bloom in the summer. Geraniums are typically low-growing, with a height of 6-12 inches, but some species can grow up to 3 feet tall. Some species have a trailing habit, making them ideal for hanging baskets and window boxes.
Care Guide
Geraniaceae are easy to care for and are suitable for both indoor and outdoor growing. Here are some tips to keep them healthy:
Water
Geraniums prefer well-draining soil and should be watered when the top inch of soil is dry. Water them deeply but do not let them sit in water as this can cause root rot.
Fertilization
Fertilize geraniums every two weeks during the growing season with a balanced fertilizer. Avoid fertilizing during the winter months.
Soil
Geraniums prefer well-draining soil with a pH between 6.0 and 7.5. They can tolerate slightly acidic soil but do not grow well in heavy clay soil.
Sunlight
Geraniums prefer full sun to partial shade. They can tolerate some shade but will not bloom as profusely as they would in full sun.
Hardiness Zones
Geraniums are hardy in USDA zones 3-8. Some species can tolerate higher zones.
Common Pests & Diseases
Geraniums are generally resistant to pests and diseases, but they can still be affected. Here are some common issues and how to treat them:
Pests
- Spider mites: Spray the plants with a mixture of water and insecticidal soap.
- Aphids: Spray the plants with neem oil or insecticidal soap.
- Whiteflies: Spray the plants with insecticidal soap.
Diseases
- Crown rot: Remove and destroy infected plants. Avoid overwatering and improve soil drainage.
- Botrytis blight: Remove and destroy infected plants. Avoid overhead watering and improve air circulation.
- Leaf spot: Remove and destroy infected leaves. Avoid overhead watering and improve air circulation.
Habitat
Geraniaceae are found in temperate regions around the world, including North America, Europe, and Asia. They grow in a variety of habitats, including meadows, woodlands, and rocky areas. Some species are adapted to arid environments and are considered succulent plants.
