Cultivation Methods

 - Soil: Well-drained sandy soil is ideal. Neutral to slightly acidic soil pH (6.0-7.0) is suitable.
 - Watering: While it can tolerate dry environments, it is recommended to provide a consistent supply of moisture. It is appropriate to water when the surface of the soil dries out.
 - Fertilizer: During the growing season, it is recommended to apply slow-release fertilizer about once a month.

Uses in the Garden
Due to its vibrant colors and strong growth, 'Sun Devil' is suitable for planting along garden edges, borders, or in the middle layer of large flowerbeds. It also attracts bees and butterflies, contributing to increased ecological diversity.

Important Pests and Control Methods - Diseases: Since leaves can become susceptible to fungal diseases due to moisture during heavy rains, maintain adequate ventilation during the rainy season.
 - Pests: Aphids and spider mites may occur; wash them off with water in the early stages, and use appropriate insecticides in severe cases.

If you prefer eco-friendly control, you can safely resolve the problem by utilizing natural predator insects or using soapy water or oil.
