Care for your Indoor Coleus Plant

Looking to brighten your home with bold, colorful foliage? The Coleus is one of the easiest and most rewarding plants to grow indoors. In this guide, you’ll learn exactly how to care for your indoor Coleus plant—covering the best soil mix, watering schedule, light exposure, and easy pruning tricks to keep it thriving year-round.

Meet Coleus: A Colorful Classic for Indoors and Out

Few plants match the sheer visual drama of Coleus (Plectranthus scutellarioides), with its vibrant, painterly foliage in shades of ruby, chartreuse, plum, copper, lime, and everything in between. Often mistaken for a fussy ornamental, Coleus is surprisingly easygoing—making it a popular pick for both seasoned gardeners and curious beginners.

A Brief History of Coleus

Coleus has been grown and admired for centuries, with early botanical explorers bringing it from Southeast Asia—particularly Java and areas of Malaysia—to Europe in the 19th century. Victorian gardeners were smitten by its bold leaf patterns and hues, often showcasing it in elaborate parterre designs. Over time, breeders have expanded the color range and leaf forms, turning Coleus into a true collector’s plant.

Originally a tender perennial in USDA Zones 10–11, Coleus is more commonly grown as a warm-weather annual or as a long-lived houseplant. While it’s prized today for its colorful leaves, earlier varieties were even cultivated for their square stems and delicate lavender flowers—though many growers now pinch off blooms to keep foliage looking sharp.

Coleus Today: Easygoing Elegance

Modern Coleus varieties thrive in a range of indoor and outdoor settings. Whether you’re looking to brighten a shady patio corner, fill a summer container with color, or add some tropical flair to a windowsill, there’s a Coleus for that.

They’re low-maintenance, fast-growing, and easy to propagate from cuttings—which makes them a favorite among home growers and market sellers alike. Indoors, they offer a pop of personality in pots year-round; outdoors, they’re summer showstoppers in beds and borders.

Caring for Your Coleus as an Indoor Plant

As said earlier, the Coleus may look like a diva, but is really quite a robust grower. It does have some specifics to mind, however. I will cover growing coleus indoors and these specific notes.

Soil

Coleus prefer a well-draining potting mix. A standard indoor houseplant mix works well.

Watering

Let the top inch of soil dry out before watering. Coleus dislike soggy roots, so err on the dry side. I’ve found that waiting for some leaves to begin wilting is a good signal to look for.

Fertilizing

For indoor plants, a Jobe’s Houseplant Food Spike once per quarter is sufficient.

Sun Exposure

Coleus appreciate a few hours of direct sun indoors—especially morning sun. A bright, east-facing windowsill is ideal. When outdoors, they do not like direct sunshine. I have my potted outdoor Coleus positioned near my front entry, where it gets a few hours of early morning dappled sun.

Pest Control

You may occasionally see fungus gnats. While mostly harmless, they’re annoying—try sprinkling Diatomaceous Earth on the soil surface and consider a yellow sticky trap if needed.

Pruning

Remove any leaves with crispy or browned edges. Pinch off any flowers as they appear (see note below).

As an Outdoor Plant

In most regions, Coleus are grown as warm-season annuals. They do best outdoors in part sun during summer months, but must be brought inside before temperatures drop below 50°F.

Notes

Coleus stems can be fragile—handle with care when moving or pruning. While their flowers are charming, letting Coleus go to seed can sap energy and shorten their lifespan. For bushier, longer-lived plants, pinch off flower spikes when they appear.

Repotting Tip: Repot your Coleus when it becomes rootbound or top-heavy—usually every 6–12 months.

If a stem does accidentally break off, don’t fret. Simply put the end of the broken stem into a new soil container (dip in a rooting hormone powder), and keep moist. It will begin to root, and you’ll have a strong, healthy “survivor!”
