Planting Your Geranium Bush

To plant a geranium bush successfully, start by choosing a location that receives at least six hours of sunlight daily, as geraniums thrive in bright, direct light. The soil should be well-draining and rich in organic matter. Amend heavy clay soils with compost or peat moss to improve drainage. Plant your geranium bush in the ground at the same depth it was in its container, spacing multiple bushes about 12-24 inches apart to ensure adequate air circulation. Water thoroughly after planting and maintain consistent moisture, allowing the soil to dry slightly between waterings. With proper care, your geranium bush will flourish, providing vibrant color and foliage throughout the growing season.

Caring for Your Geranium Bush

• Watering: Water your geraniums deeply once a week, allowing the soil to dry out slightly between waterings. Avoid overhead watering to prevent leaf spot diseases.
• Pruning: Regularly deadhead spent blooms to encourage new growth and prune any leggy or damaged stems to promote a bushier plant.
• Fertilization: Feed your geraniums every four to six weeks during the growing season with a balanced, water-soluble fertilizer to support healthy growth and flowering.
• Sunlight: Ensure your geraniums receive at least six hours of sunlight each day. They thrive in full sun but can tolerate partial shade.
• Soil: Plant your geraniums in well-draining soil. If you are growing them in pots, make sure the containers have drainage holes.
• Overwintering: If you live in a cooler climate, bring your geraniums indoors before the first frost. Keep them in a bright, cool location until spring.

Common Pests and Diseases

Geranium bushes, while hardy and vibrant, are not immune to certain pests and diseases that can mar their beauty and health. Among the most common pests are aphids, which cluster on the undersides of leaves, sucking the sap and weakening the plant. Another frequent visitor is the geranium budworm, which burrows into flower buds, preventing them from blooming. To combat these pests, a combination of natural predators like ladybugs, neem oil applications, or insecticidal soaps can be effective.

When it comes to diseases, geraniums can fall victim to bacterial blight and fungal infections such as rust and powdery mildew. Bacterial blight manifests as black, water-soaked spots on leaves, eventually leading to plant death if untreated. Rust appears as orange or yellowish spots on the undersides of leaves, while powdery mildew coats leaves in a white, powdery substance. Preventing these diseases starts with ensuring proper air circulation around the plants and avoiding overhead watering. Infected plants or parts should be removed and destroyed, and fungicides may be applied as a preventive measure during humid or wet conditions.
