Gardening Advice

Sunlight

Prefers full sun but can tolerate partial shade. In areas with strong direct sunlight, some shade during the hottest hours can help prevent stress.

Watering

Drought-tolerant but benefits from occasional deep watering during the growing season. Avoid waterlogging by ensuring good drainage.

Soil

Thrives in well-drained, sandy soil. Prefers neutral to alkaline soil; adding lime can enhance growth.

Fertilizer

Apply a balanced slow-release fertilizer monthly during the growing season. Avoid over-fertilizing, as it can reduce flower production in favor of foliage growth.

Hardy to cold climates and usually requires no special protection. In extremely cold areas, mulching around the base helps protect roots.
