To showcase the vibrant hues of coleus leaves, nurture them in a location that receives either partial or full sunlight. These plants flourish in soil that is moist but well-drained. Although coleus are perennials, they cannot tolerate cold weather and must be grown as annuals in the United Kingdom, with planting usually taking place in May after the frost has passed. Alternatively, bring them indoors during autumn or cultivate cuttings in summer for new plants during spring. Coleus grow best at the front of a garden border or in pots on patios. If grown as a houseplant, make sure to select a well-lit area that still affords some shade. When planting, introduce multi-purpose compost into the soil and ensure that the hole is slightly larger than the original pot. Water the plant thoroughly after introduction. For healthy growth, pinch the central stem to promote a bushier appearance and water regularly during the summer. In preparation for winter, relocate potted coleus plants indoors before the first frost. While outdoor coleus do not often suffer from diseases, indoor or conservatory plants may attract whitefly, mealybugs, or scale insects.
