Watering. Keep soil consistently moist but not soggy. Water when the top inch of soil feels dry. Reduce watering in cooler months.
Fertilizing. Feed coleus with a balanced, water-soluble fertilizer every 4 to 6 weeks during the growing season (spring through summer). Avoid over-fertilizing, which can reduce leaf color vibrancy.
Coleus is an easy-to-grow plant that thrives in partial shade to bright indirect light. It prefers moist, well-draining soil and benefits from regular watering, but avoid waterlogging. It may suffer from leaf drop or color fading if light is too low or watering is inconsistent. Minimal maintenance is needed, mainly occasional pinching to encourage bushier growth.
