Ageratum

How to Care for Ageratum

Sunlight: Ageratum thrives in full sun to partial shade. It prefers at least 4-6 hours of sunlight daily, but it can tolerate light shade in hot climates to prevent stress.

Soil: Plant Ageratum in well-draining, fertile soil enriched with organic matter. A slightly acidic to neutral pH of 6.0-7.0 is ideal for healthy growth.

Water: Ageratum prefers consistently moist soil but does not tolerate waterlogging. Water regularly, ensuring the soil stays evenly moist but not soggy. Allow the top inch of soil to dry out slightly between waterings.

Fertilizer: Feed Ageratum every 4-6 weeks during the growing season with a balanced, slow-release fertilizer or a liquid fertilizer diluted to half strength. Avoid over-fertilizing, as it can reduce flowering.

Pruning: Deadhead Ageratum regularly to encourage continuous blooming and prevent the plant from going to seed. Pinch back leggy growth to maintain a compact and bushy shape.

Pests and Diseases: Ageratum is generally low-maintenance but may occasionally attract aphids, spider mites, or whiteflies. Keep an eye out for signs of leaf spot, botrytis, or root rot, often caused by overwatering or overcrowding.

Winter Hardiness: Ageratum is frost-sensitive and typically grown as an annual in most climates. In USDA zones 10-11, it can survive as a perennial. Protect plants from frost and cold by growing them in containers that can be moved indoors or starting new plants each spring.
