Water: Puget sound gumweed flourishes in high humidity and regular rainfall, necessitating weekly watering to sustain health. As an evergreen, it conserves water by retaining leaves during dry periods, allowing it to endure less frequent watering.

Fertilize: Fertilize puget sound gumweed with balanced, slow-release fertilizers in spring for healthy growth and blooms. Use sparingly to protect ecosystems, adjusting for seasonal patterns and applying lighter feedings in fall. Always follow label instructions and water the soil before and after fertilizing.

Pruning: Puget sound gumweed thrives with early to late spring pruning, promoting bushiness and vibrant blooms. Start by removing dead parts, then trim back by one-third. This encourages healthy new growth, prevents legginess, and maintains its attractiveness as a garden feature.

Propagation: Puget sound gumweed can be reliably propagated through stem cuttings using healthy, non-flowering shoots. Applying rooting hormone and planting in well-draining soil with consistent moisture fosters rooting. A warm, sheltered environment enhances growth, leading to strong new plants.
