About Chiric Sanango

Brunfelsia grandiflora · also called Chiric Sanango, Yesterday-Today-and-Tomorrow · tropical

Brunfelsia grandiflora is a Peruvian rainforest shrub prized for fragrant tubular flowers that open deep purple, fade to lavender, then white over three days. In frost-free climates it blooms nearly year-round in dappled light. Indoors it needs bright indirect light, consistent moisture, and high humidity to perform well. All parts are poisonous.

Mature size: 1.5-2.5 m tall, 1-1.5 m wide in containers; up to 4 m outdoors in tropical climates

How to tell chiric sanango needs repotting

Repotting on a calendar is less reliable than reading the plant. For chiric sanango, watch for these signs:

Roots poking out of the drainage holes or coiling visibly around the inside of the pot.
You are watering far more often than you used to because the rootball dries out within a day or two.
Water runs straight through and out the bottom without soaking in.
Top growth has slowed or new chiric sanango leaves are noticeably smaller than older ones despite good light.

How often to repot chiric sanango

Every 12–18 months — sooner if roots show fast. Chiric Sanango's growth habit — upright, branching evergreen shrub — sets the pace. Brunfelsia grandiflora is a Peruvian rainforest shrub prized for fragrant tubular flowers that open deep purple, fade to lavender, then white over three days. In frost-free climates it blooms nearly year-round in dappled light. Indoors it needs bright indirect light, consistent moisture, and high humidity to perform well. All parts are poisonous.

What size pot to step chiric sanango up to

Step up one pot size — about 2–3 cm (an inch) wider. Chiric Sanango grows fast, so it will fill that space within a season, but jumping several sizes at once still backfires: the unused soil stays soggy and rots even a vigorous root system. One size at a time, every year or so, is the rhythm.

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 chiric sanango

Early spring, just as new growth restarts, is the ideal window for chiric sanango. 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 chiric sanango

Time it for spring. Repot chiric sanango in early spring as growth restarts so it re-roots quickly into the fresh soil.
Choose one size up. Pick a pot about 2–3 cm wider with drainage holes. One step only — a much bigger pot stays soggy and rots roots.
Ease the plant out. Water lightly the day before, then tip chiric sanango out and gently loosen any roots circling the bottom of the rootball.
Repot at the same depth. Put a layer of fresh well-draining, humus-rich, slightly acidic loam in the new pot, set the plant so its soil line is unchanged, and backfill, firming lightly.
Water and pause feeding. Water once to settle the soil. Hold off fertiliser for about a month — fresh mix already has nutrients and feeding now burns new roots.

Aftercare

Water chiric sanango once to settle the soil, then let the surface dry before watering again — fresh mix around the roots stays wetter than the old compacted ball, so the commonest post-repot mistake is overwatering. Keep it out of direct sun for a week or two while roots re-establish. Do not fertilise for about 4 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for chiric sanango

Chiric Sanango wants well-draining, humus-rich, slightly acidic loam. Use a mix of 2 parts quality peat-free compost, 1 part perlite, and 1 part bark to replicate the organic, free-draining rainforest floor. Target pH 5.5-6.5. Good drainage is essential — waterlogged roots rot rapidly. Repot every 2-3 years in spring. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting chiric sanango — frequently asked questions

How often should you repot chiric sanango?

Every 12–18 months — sooner if roots show fast for chiric sanango. Repot chiric sanango roughly every 12–18 months, in early spring as growth restarts. It grows fast and circles its pot quickly, so step up one size (about 2–3 cm wider) into fresh well-draining, humus-rich, slightly acidic loam. Don't jump several sizes — that soggy excess soil is what rots vigorous roots.

What size pot does chiric sanango need?

When is the best time of year to repot chiric sanango?

Can you put chiric sanango straight into a much bigger pot?

No. Even a fast-growing chiric sanango 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 chiric sanango after repotting?

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