Water: Originating from arid regions, chilean tarweed thrives on minimal moisture with strong drought tolerance. Weekly watering suffices, favoring well-draining soil to avoid standing water. Typically grown outdoors, chilean tarweed flourishes during infrequent rain, making it suitable for xeriscaping and dry climate gardens.

Fertilize: For chilean tarweed, apply balanced nutrition fertilizer once in spring and mid-summer for optimal growth. High-nitrogen fertilizers aid vegetative development but should be used sparingly. Incorporate into soil near roots, avoid foliage contact, and irrigate afterward. Follow package instructions for appropriate dosage.

Pruning: Chilean tarweed is an aromatic herbaceous plant with sticky foliage and yellow flowers. Pruning techniques involve pinching young stems and removing spent flowers during early to late spring. This promotes branching, enhances air circulation, and reduces disease risk, promoting overall plant vigor.

Propagation: Chilean tarweed is propagated by sowing seeds in well-draining soil with adequate sunlight. Seeds should be sown thinly and covered lightly. Keep the soil moist but not waterlogged to promote germination. Once established, thin seedlings and provide regular care for optimal growth.
