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.
Growth habit: Upright, branching evergreen shrub
What fertiliser chiric sanango actually wants — and why
Chiric Sanango is an easy, light foliage feeder — a half-strength balanced liquid feed through the growing months keeps it green without forcing weak, sappy growth.
A balanced general houseplant feed (roughly even N-P-K) is exactly right — it is grown for foliage, so steady, moderate nitrogen for healthy leaves is the goal, not a bloom or root formula.
For the language behind the three numbers on the bottle — what nitrogen, phosphorus and potassium each do — see the NPK ratio explained entry. The short version for chiric sanango: match the feed to the job the plant is doing right now, not to a generic “plant food” on the shelf.
How often to feed chiric sanango, and which months
Feeding only earns its keep while the plant is in active growth and can use the nutrients — pour feed into a dormant or low-light plant and it simply builds up as root-burning salt. For chiric sanango:
Feed every 2-3 weeks from spring through summer with a balanced liquid fertiliser (NPK 10-10-10) diluted to half strength. Switch to a low-nitrogen, high-potassium feed in late summer to harden growth and encourage flower-bud set. Do not feed in autumn and winter. Treat that as every 2-3 weeks between spring through early autumn (roughly March to September); ease off in autumn and stop entirely in the low light of winter.
The dormant-season rule matters more than the exact interval: skip feeding entirely when chiric sanango is resting. For the wider context on indoor feeding rhythms across the seasons, the houseplant fertiliser schedule walks through the year month by month.
What strength to mix for chiric sanango
Half strength is the safe default for chiric sanango — houseplant feeds are formulated strong, and the diluted dose is gentler on the roots while still ample for foliage.
Feeding always goes onto already-damp soil, never dry roots — water chiric sanango first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the chiric sanango watering schedule.
Signs you are over-feeding chiric sanango
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for chiric sanango:
- Brown, crispy leaf tips and edges with no sign of underwatering.
- A white, crusty salt deposit on the soil surface or pot rim.
- Weak, pale, stretched new growth that flops.
- Lower leaves yellow and drop while the soil is correctly watered.
Signs you are under-feeding chiric sanango
- Uniformly pale or yellow-green leaves, oldest first.
- Noticeably small new leaves and stalled growth in good light and season.
- A generally tired, lacklustre look despite correct watering and light.
If the symptoms point at watering, light or roots rather than nutrition, the full chiric sanango care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Flush the pot of chiric sanango with plain water until it runs freely from the base every couple of months in the feeding season — it washes out the fertiliser salts that cause brown tips.
Organic vs synthetic feeds for chiric sanango
Organic options
A diluted seaweed or worm-casting feed, or fish emulsion if you can tolerate the smell indoors. UK: Westland or Baby Bio Organic, dilute seaweed; US: Espoma Indoor! or Neptune's Harvest fish & seaweed. Slow, gentle and hard to overdo.
Synthetic / liquid feeds
A general-purpose houseplant liquid at half strength — UK: Baby Bio, Westland Houseplant Feed or Phostrogen; US: Miracle-Gro Indoor Plant Food or Schultz. Convenient and fast-acting; the only risk is overdoing it.
Brand names are examples, not endorsements, and UK and US ranges differ — check the label’s own NPK and dilution rate, since formulations change.

What does over-feeding chiric sanango look like?
Brown, crispy leaf tips and edges with no sign of underwatering. A white, crusty salt deposit on the soil surface or pot rim. Weak, pale, stretched new growth that flops. Lower leaves yellow and drop while the soil is correctly watered. Feeding chiric sanango year-round on a fixed schedule, including dark winter months, is the most common mistake — it cannot use the nutrients in low light and the surplus simply burns the roots and crusts the soil.
Should I flush the soil of chiric sanango?
Flush the pot of chiric sanango with plain water until it runs freely from the base every couple of months in the feeding season — it washes out the fertiliser salts that cause brown tips.
