About Nance
Byrsonima crassifolia · also called Nance, Nanche · tropical
Nance is a small to medium tropical tree or large shrub native to Central America and northern South America, bearing small, round, yellow to orange-yellow fruits with a distinctive fermented, buttery aroma. Widely eaten fresh, fermented into chicha, or made into aguas frescas and ice creams, it is adapted to poor, acidic savanna soils and full sun.
Growth habit: Slow-growing, multi-branched small tree or large shrub with a dense, rounded crown; often gnarled on poor soils
Watch for — Very slow establishment: Nance is notably slow-growing, especially on its native poor soils. Young trees may show little visible growth in the first 1–2 years as they invest in root development. Patience is key; avoid the temptation to over-fertilise to speed growth, which can be counterproductive.
What fertiliser nance actually wants — and why
Nance 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 nance: 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 nance, 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 nance:
Light fertilisation only — excessive nutrients, especially nitrogen, promote vegetative growth at the expense of fruiting and can harm trees adapted to poor soils. A light application of low-nitrogen organic fertiliser or compost once per year at the start of the wet season is sufficient. Avoid synthetic high-nutrient fertilisers. Treat that as sparingly through the growing season 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 nance 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 nance
Half strength is the safe default for nance — 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 nance first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the nance watering schedule.
Signs you are over-feeding nance
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for nance:
- 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 nance
- 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 nance care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Flush the pot of nance 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 nance
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.

Lower leaves yellow and drop while the soil is correctly watered. Feeding nance 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 nance?
Flush the pot of nance 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.
