About 'Carolina Reaper' Pepper

Capsicum chinense 'Carolina Reaper' · also called Carolina Reaper super-hot chilli · edible

'Carolina Reaper' is among the world's hottest chillies, averaging over 1.6 million Scoville heat units with a wrinkled, scorpion-tailed pod. A Capsicum chinense super-hot, it demands a long, hot season and is best grown under cover in cool climates. Handle fruit with gloves — capsaicin causes severe skin, eye and airway irritation.

Mature size: 70-120 cm tall and 50-70 cm wide.

How to tell 'carolina reaper' pepper needs repotting

Repotting on a calendar is less reliable than reading the plant. For 'carolina reaper' pepper, watch for these signs:

Roots circling the bottom of the module or pot, or poking out of the drainage holes.
The seedling dries out within a day and growth has visibly stalled.
Roots are white and matted in a tight spiral when you tip the plant out.
It has outgrown its current container for the stage of the season — pot 'carolina reaper' pepper on before it becomes hard root-bound.

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 'carolina reaper' pepper

Pot on seedlings as they grow; not a perennial repot. 'Carolina Reaper' Pepperis grown for one season, so the question is really “how often to pot on” — keep moving it up before the roots circle. Bushy, densely branched upright annual (tender perennial) that woodens at the base; stake heavily fruiting plants to prevent splayed, broken stems..

What size pot to step 'carolina reaper' pepper up to

Pot 'carolina reaper' pepper on gradually — a seedling jumped straight into a huge pot sits in cold, wet, airless soil and stalls. Step up one or two sizes at a time as the roots fill each container, finishing in a large final pot or the ground. The aim is roots that never circle and never check.

Not sure of the exact diameter? Our pot size calculator takes the current pot and root spread and tells you the right next size — it deliberately recommends a single step up, never a big jump.

The best time of year to repot 'carolina reaper' pepper

Pot 'carolina reaper' pepper on through the active growing season, whenever roots fill the current container — there is no single date, just "before it becomes root-bound". Avoid potting on during a cold snap.

Step-by-step: repotting 'carolina reaper' pepper

Pot on before it is root-bound. Check 'carolina reaper' pepper regularly; move it up as soon as roots reach the edge of the cell or pot, not after they have circled.
Step up one or two sizes. Choose the next container up — not a giant one. Cold, wet, unused soil around a small root system stalls seedlings.
Knock it out gently. Support the stem, tip the pot, and ease the rootball out without breaking it. A little teasing of circled roots at the base is fine.
Pot into rich mix. Set it into fresh rich, free-draining loam or quality potting mix at the same depth (tomatoes are the exception — they can go deeper to root along the stem).
Water in and grow on. Water well, keep it in good light, and resume feeding once it is established and growing again.

Aftercare

Water 'carolina reaper' pepper in well and keep it in bright light; a freshly potted-on seedling can wilt for a day while roots settle, so do not overcompensate by drowning it. Do not fertilise for about 1 week — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for 'carolina reaper' pepper

'Carolina Reaper' Pepper wants rich, free-draining loam or quality potting mix. Needs warm, fertile, well-drained soil at pH 6.0-6.8 amended with compost. In pots use peat-free compost with added perlite to prevent cold, soggy roots. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting 'carolina reaper' pepper — frequently asked questions

How often should you repot 'carolina reaper' pepper?

Pot on seedlings as they grow; not a perennial repot for 'carolina reaper' pepper. 'Carolina Reaper' Pepper is a seasonal crop, so you pot it on as a growing plant rather than repotting a perennial. Step seedlings up gradually into rich, free-draining loam or quality potting mix so the roots never circle the cell, ending in a large final container. A root-bound transplant stalls and never fully recovers.

What size pot does 'carolina reaper' pepper need?

When is the best time of year to repot 'carolina reaper' pepper?

Can you put 'carolina reaper' pepper straight into a much bigger pot?

No. Even a fast-growing 'carolina reaper' pepper should only go up one pot size at a time. A vastly oversized pot holds a reservoir of wet soil the roots cannot reach, which stays cold and soggy and rots the roots — the opposite of what you wanted.

Should you fertilise 'carolina reaper' pepper after repotting?

Not immediately. Wait about 1 week after repotting 'carolina reaper' pepper. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
