About Plectranthus scutellarioides 'Wizard Scarlet'

Plectranthus scutellarioides 'Wizard Scarlet' · also called Wizard Scarlet Coleus, Scarlet Coleus · flowering

Wizard Scarlet is a compact, seed-grown coleus with rich scarlet-red leaves narrowly edged in green, prized for uniform habit and quick establishment. Part of the dwarf Wizard series, it suits bedding, edging, and containers in shade to part sun. Grown for vivid foliage, not its small flowers. Easy and fast, it is a tender perennial grown as an annual.

Mature size: 25-35 cm tall and 25-30 cm wide.

How to tell plectranthus scutellarioides 'wizard scarlet' needs repotting

Repotting on a calendar is less reliable than reading the plant. For plectranthus scutellarioides 'wizard scarlet', watch for these signs:

Roots spiralling thickly out of the drainage holes or pushing the whole plant up out of the pot.
The pot is so packed that water runs straight through in seconds and barely wets the soil.
It has split a plastic pot, or the rootball is a solid mass with almost no soil left when you slide it out.
Growth and (for plectranthus scutellarioides 'wizard scarlet') flowering have clearly stalled despite good light and feeding — but remember this plant likes being snug, so a little crowding alone is not a reason to repot.

For the underlying biology of a pot-bound root system and why it stalls a plant, see our guide to spotting and fixing a root-bound plant.

How often to repot plectranthus scutellarioides 'wizard scarlet'

Only every 2–4 years, when genuinely crowded. Plectranthus scutellarioides 'Wizard Scarlet' is one of the plants that genuinely prefers a snug pot — it grows and flowers better with its roots a little restricted, so resist the urge to repot it on schedule. Compact, dwarf, well-branched bushy habit; uniform and tidy, ideal for mass bedding and edging..

What size pot to step plectranthus scutellarioides 'wizard scarlet' up to

Go up only one pot size — roughly 2–3 cm (about an inch) wider in diameter, no more. Plectranthus scutellarioides 'Wizard Scarlet' positively prefers a snug pot: it flowers and grows better when the roots are a little restricted. The single biggest repotting mistake here is over-potting — dropping plectranthus scutellarioides 'wizard scarlet' into a pot two or three sizes up. All that surplus soil holds water the small root system cannot use, stays cold and wet, and rots the roots within weeks. When in doubt, choose the smaller pot.

The best time of year to repot plectranthus scutellarioides 'wizard scarlet'

Early spring, just as new growth restarts, is the ideal window for plectranthus scutellarioides 'wizard scarlet'. The plant is moving into its strongest growth phase and re-roots into fresh soil quickly. Avoid repotting in winter dormancy or, for flowering plants, while it is in bud or bloom — recovery is slowest then and you risk dropping the flowers.

Step-by-step: repotting plectranthus scutellarioides 'wizard scarlet'

Confirm it actually needs it. Slide plectranthus scutellarioides 'wizard scarlet' out and check the roots. Only continue if it is genuinely packed — this plant prefers a snug pot, so if there is still soil and room, put it straight back.
Pick a pot only one size up. Choose a pot just 2–3 cm wider with good drainage. Resist anything bigger; over-potting is the main killer here.
Ease it out gently. Water lightly the day before, then tip plectranthus scutellarioides 'wizard scarlet' out, supporting the base. Tease the outer roots free only enough to stop them circling.
Repot at the same depth. Add a layer of fresh fertile, moisture-retentive, well-drained potting mix, set the plant so the soil line sits exactly where it did before, and backfill around the sides, firming lightly.
Settle it in. Water once to settle the soil, then let it sit. Hold off on more water until the top of the soil dries — fresh soil around a small root system stays wet for a while.

Aftercare

Because the new soil holds more water than the old crammed rootball did, ease right back on watering — let the top of the soil dry before you water plectranthus scutellarioides 'wizard scarlet' again, or you will rot the roots in the very pot you just moved it to. Keep it out of harsh direct sun for a fortnight. Do not fertilise for about 4 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for plectranthus scutellarioides 'wizard scarlet'

Plectranthus scutellarioides 'Wizard Scarlet' wants fertile, moisture-retentive, well-drained potting mix. A good peat- or coir-based mix with organic matter that stays moist but drains freely; slightly acidic to neutral pH (6.0-7.0). Enrich garden soil with compost to support steady growth and colour. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting plectranthus scutellarioides 'wizard scarlet' — frequently asked questions

How often should you repot plectranthus scutellarioides 'wizard scarlet'?

Only every 2–4 years, when genuinely crowded for plectranthus scutellarioides 'wizard scarlet'. Only repot plectranthus scutellarioides 'wizard scarlet' every 2–4 years, and only when it is genuinely root-bound — it flowers and grows best slightly crowded. Step up just one pot size in spring using fertile, moisture-retentive, well-drained potting mix. The key mistake is over-potting: a too-big pot stays wet and rots the roots.

What size pot does plectranthus scutellarioides 'wizard scarlet' need?

When is the best time of year to repot plectranthus scutellarioides 'wizard scarlet'?

Does plectranthus scutellarioides 'wizard scarlet' like to be root-bound?

Yes — plectranthus scutellarioides 'wizard scarlet' genuinely flowers and grows best when slightly pot-bound, so do not rush to repot it. The mistake to avoid is over-potting into a much larger pot: the excess soil stays wet, the roots cannot use it, and the plant rots. Only repot every few years and only one snug size up.

Should you fertilise plectranthus scutellarioides 'wizard scarlet' after repotting?

Not immediately. Wait about 4 weeks after repotting plectranthus scutellarioides 'wizard scarlet'. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
