Gardening Advice

Ageratum thrives in sunny spots but can also grow in partial shade. It prefers well-draining soil and benefits from a thorough watering whenever the soil becomes dry. Good air circulation is also important to prevent pests and diseases.

For fertilizing, apply a slow-release fertilizer when planting and add a monthly feed during the growing season to encourage flowering. Regular deadheading of spent blooms encourages continuous flowering throughout the season.
