How to Repot a Coleus

Coleus scutellarioides

Reviewed by Kiersten Rankel, M.S.

Quick Answer

Repot a Coleus every 1 to 2 years into a pot that's 1 to 2 inches wider than the current pot. Use a rich, well-draining potting mix with a little extra perlite. Spring through early summer is the best window, when warmth and longer days speed root recovery.

How to Know It's Time to Repot

Coleus grows fast and fills a pot with fine roots in a single season, so the signs of an outgrown pot show up clearly. Watch for these four signals when growth slows or leaves start losing their color.

1

Roots circle the bottom of the pot or push out through the drainage holes.
2

The plant has roughly doubled in size since you last potted it up.
3

Soil dries out within a day of a thorough watering during active growth.
4

Leaves are smaller, duller, or losing their bright color compared to earlier in the season.

One sign on its own can have other causes, so wait until two or more line up before repotting. Most Coleus plants need a fresh pot every 1 to 2 years, faster than most houseplants because they grow so quickly.

The Best Time of Year to Repot

Coleus recovers fastest from repotting when it's in active growth, which kicks in with longer days and warmer rooms. Spring through early summer is the sweet spot.

Avoid repotting in winter, when growth slows and freshly disturbed roots are slow to heal. Use the map below to find your window.

How to Choose a Pot and Soil Mix

Pot Size

Move up to a pot that's 1 to 2 inches wider than the current pot. That gives the roots enough fresh soil for the next year of growth, with room to spread but not so much extra space that wet soil sits around them and rots.

Pot Material

Plastic and glazed ceramic are both good fits for Coleus. They hold moisture long enough between waterings, which matters for a plant that wilts fast in dry soil.

Terracotta dries out quickly and can leave the plant thirsty during a warm summer, so it's a weaker choice unless you don't mind watering often. Whichever material you pick, make sure the pot has drainage holes. Soggy roots rot fast.

Soil Mix

Mix three parts standard potting soil with one part perlite for the rich, well-draining blend Coleus wants. A small handful of compost mixed in gives the plant the steady nutrients it needs to keep pushing out colorful leaves.

Skip cactus or succulent mixes. They drain too fast and leave the plant thirsty during peak growth.

How to Repot a Coleus, Step by Step

1

Water the day before. Give the plant a thorough drink the day before repotting. Moist soil holds the root ball together when you slide it out and keeps the fine feeder roots from tearing.
2

Pick the new pot. Choose a pot that's 1 to 2 inches wider than the current pot, with drainage holes. Layer an inch of fresh mix in the bottom so the root ball will sit at the same height it did before.
3

Pinch back the stems. Coleus grows leggy fast, so use a pinch and a repot together. Pinch the tip of each main stem back to the next set of leaves. This balances the leafy top against any roots you disturb and makes the plant bushier.
4

Slide the plant out. Tip the pot onto its side and gently work the root ball loose. Hold the base of the main stem rather than pulling on the leaves. If the plant is stuck, run a butter knife around the inside edge of the pot to release it.
5

Set it in the new pot. Center the plant at the same depth it was growing before. Fill in around the sides with fresh mix, pressing gently to remove air pockets. Don't bury the lower stem any deeper than it was before.
6

Water and give it bright light. Water slowly until you see it run out the drainage holes. Set the plant somewhere with bright indirect or filtered sun, which keeps the leaf colors vivid. Hold off on fertilizer for 4 to 6 weeks so the roots can heal.

What to Expect After Repotting

Day 1 to 3

A noticeable droop in the first day or two is common with Coleus. The leaves recover quickly once the roots take hold in the new soil.

Keep the soil lightly moist, give the plant bright filtered light, and skip fertilizer for now. The droop usually clears within 48 hours.

Week 1 to 2

Fresh leaves unfurling at the pinched tips are the signal that the plant has rooted in and is branching out. From here, you can ease into your regular watering rhythm.

Start half-strength liquid fertilizer once you see clear new growth, and build up to full strength over the next two or three feedings. Coleus is a moderate feeder during the growing season.

Got More Questions?

Does Coleus like to be root-bound?

No. Coleus grows biggest and keeps its leaf color brightest when the roots have room to spread. A pot-bound plant tends to go leggy and lose its vivid color.

Can I repot my Coleus right after I bring it home?

Give it a week to adjust to your home's light first, unless it's clearly root-bound when you bring it home. Coleus recovers from stress faster than most houseplants, so the adjustment period is shorter.

What if my pot doesn't have drainage holes?

Don't repot directly into it. Coleus rots fast in standing water, so plant in a nursery pot with drainage and slip that inside the decorative pot. If you want to use the decorative pot directly, drilling works for unglazed terracotta, but glazed ceramic and thin pots tend to shatter. Use a diamond bit with a slow drip of water if you try it.

Should I pinch the stems when I repot?

Yes. Coleus benefits from a light pinch every few weeks anyway, and combining a pinch with a repot keeps the plant bushy. Cut each main stem tip back to the next pair of leaves with clean scissors or just pinch with your fingers.

Can I propagate cuttings when I repot?

Yes. The stem tips you pinch off root easily in water or moist potting mix within a week or two. This is the easiest way to keep a Coleus going year to year, since the parent plant tends to get leggy after a season or two.

Should I repot my Coleus before overwintering indoors?

If you're bringing a Coleus inside from a summer outdoors, repot before the move only if it's clearly root-bound. Otherwise, just check for pests, give it a light pinch, and bring it in. Two stressors (move plus repot) at once is harder on the plant than either alone.
