Water: Originating from arid regions, skeletonleaf bur ragweed exhibits high drought tolerance and is ideal for xeriscaping. Water sparingly, about once a week, to align with its natural dry habitat. Its extensive root system effectively utilizes available water during the growing season.

Fertilize: Skeletonleaf bur ragweed thrives with a balanced fertilizer (equal nitrogen, phosphorus, potassium) every 4-6 weeks during the growing season. Use sparingly to avoid over-fertilization, and water the soil beforehand. Reduce fertilization in dormancy to maintain health and vigor.

Pruning: Skeletonleaf bur ragweed is a hardy perennial with fuzzy leaves and burrs. Prune in early to late spring to manage growth and shape, removing dead stems and thinning crowded areas for better airflow. Clean, sharp tools are essential for effective and safe pruning, promoting healthier growth.

Propagation: Skeletonleaf bur ragweed is resilient and propagated via sowing. Seeds should be scattered on well-drained soil with consistent moisture and protection from harsh weather. Once seedlings are sturdy, transplant them with adequate spacing to ensure mature size and resource availability.
