Caring for physoplexis involves ensuring ample sunlight, moderate water, and well-draining soil with a preference for cooler temperatures. Gardeners must watch for root rot, pests like aphids, and frost damage. During spring, increase watering as growth resumes; in summer, protect from intense heat; autumn is ideal for division; and in winter, reduce watering and provide frost protection. Consistent monitoring and seasonal adjustments are crucial for physoplexis's health.
