Leaf size: approximately 4 inches.

Plectranthus scutellarioides requires watering every 7–10 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Coleus thrives in bright indirect light light conditions. The optimal light range is 100–500 lux. Avoid placing Coleus in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Plectranthus scutellarioides grows best at temperatures between 60°F and 80°F. Coleus prefers humidity levels of 40–60%.

Well-draining soil mix with added perlite for good aeration. Good drainage is essential for Coleus to prevent waterlogging, which leads to root rot and fungal issues.

Repot every 1-2 years in spring. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.
