Watering. Keep the soil consistently moist but not soggy. Water when the top inch of soil feels dry. Avoid letting the plant sit in water to prevent root rot.
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 cause leggy growth.
Coleus is a tough and easy-to-grow plant that thrives in partial shade to bright indirect light. It prefers moist but well-drained soil and benefits from regular watering. If it gets too dry or too much direct sun, the leaves may wilt or lose their vibrant color. Pruning helps keep the plant bushy and healthy.
