Water: Brazilian joyweed thrives in humid, tropical conditions and prefers consistent moisture, with weekly watering essential. As an evergreen, it requires regular hydration to maintain its foliage. Typically grown outdoors, mulching is beneficial for retaining soil moisture and minimizing evaporation.

Fertilize: To care for brazilian joyweed, use high-nitrogen fertilizer every 4-6 weeks during growth, then bi-monthly in winter. Water before application to prevent root burn and use half strength for indoor plants. Adjust fertilization seasonally and utilize a balanced N-P-K ratio in spring for flowering promotion.

Pruning: Brazilian joyweed has vibrant foliage and prefers warm climates. Prune lightly in early to late spring to maintain shape and remove dead stems. This encourages bushier growth, enhances air circulation, and prevents disease. Always sterilize tools before pruning for optimal health.

Propagation: Propagate brazilian joyweed during Spring and Summer using cuttings. Fresh root growth indicates successful propagation. Keep cuttings moist and ensure they receive indirect sunlight for optimal results.

Repotting: Repot brazilian joyweed every 2-3 years in spring to accommodate growth. Use a larger pot with drainage and well-draining soil, then water thoroughly. Place in indirect light for recovery, treating brazilian joyweed gently as it is sensitive to changes.
