Care at a glance
Light
Most houseplants will scorch where nance thrives. Give it the windowsill you'd otherwise leave empty because everything else burned there. A full-sun species native to open tropical savannas and dry forest edges. Requires at least 6–8 hours of direct sun daily. Will not thrive in shade — responds to reduced light with weak, lanky growth and minimal flowering. Ideal for exposed, sunny garden positions. A plant moved abruptly from low light to direct sun bleaches in 48 hours — always acclimatise over a week.
Watering
Aim for every 14–21 days; highly drought-tolerant when established for nance, but treat that as a starting point rather than a rule. A south-facing summer windowsill will dry the pot twice as fast as a north-facing winter room. Lift the pot; if it feels noticeably lighter than it did wet, water it. Naturally adapted to seasonally dry tropical savannas with pronounced dry seasons. Established trees are highly drought-tolerant and rarely need supplemental irrigation beyond natural rainfall. Young plants need regular watering for the first 1–2 years. Overwatering is more damaging than drought for this species.
Soil and pot
Nance grows best in poor, acidic, well-draining sandy or clay-sandy savanna soil. One of the most soil-tolerant tropical fruit trees — naturally grows in nutrient-poor, highly acidic (pH 4.0–6.5), lateritic savanna soils where most other trees cannot establish. Rich, fertile soil can actually inhibit fruiting. Good drainage is important; does not tolerate waterlogging. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.
Humidity and temperature
Nance sits happiest at around 40–80% RH humidity and 18–35°C (64–95°F). Tolerates a wide range of humidity levels, from the relatively dry savannas of its native habitat to more humid tropical forest margins. Not dependent on high humidity. Better adapted to periodic dry conditions than most tropical fruit trees. If you keep the room above 18–35°C year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.
Fertilising
Feed nance sparingly. 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. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.
Common problems
Below are the issues we see most often on nance in the Growli community. Each is annotated with the most common cause so you know where to start.
- 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.
- Fruiting inconsistency in cultivation — Trees transplanted into rich garden soils often produce abundant foliage but no fruit. Mimicking poor, slightly acidic soil conditions and reducing irrigation stress the tree into fruiting mode. Established wild or lightly managed trees fruit more reliably than heavily tended garden specimens.
- Scale insects and sooty mould — Soft scale insects can colonise branches, excreting honeydew that leads to black sooty mould coating leaves and reducing photosynthesis. Treat with horticultural oil spray and ensure good air circulation within the canopy.
Propagation
Seed is the primary propagation method — sow fresh seed in acidic, low-fertility substrate and germinate at 25–30°C; germination can be slow and irregular (4–12 weeks). Cuttings are difficult to root. Air-layering has been reported with variable success. Grafting onto seedling rootstock is used in research trials but not common in home cultivation. Trees are slow to produce fruit from seed — typically 5–8 years. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.
Toxicity to pets
Nance is pet-safe. Byrsonima crassifolia (Nance) is not individually listed by ASPCA. It belongs to Malpighiaceae, a family with no widely documented toxic principles for companion animals. The fruit is extensively consumed by humans and wildlife with no reported toxicity. No known toxic alkaloids, glycosides, or irritant compounds are documented for this species. Reasonable caution is advised as with any unfamiliar plant, but it is not considered toxic. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).
Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.
Nance care — frequently asked questions
What is the common name for Byrsonima crassifolia?
Byrsonima crassifolia is most commonly called Nance, but it is also known as Nance, Nanche, Golden Spoon, Savanna Serrette, Changunga. The names refer to the same species, so care instructions for Nance apply identically to anything sold as Nanche.
How much light does nance need?
Nance grows best in direct sun (at least 4-6 hours). A full-sun species native to open tropical savannas and dry forest edges. Requires at least 6–8 hours of direct sun daily. Will not thrive in shade — responds to reduced light with weak, lanky growth and minimal flowering. Ideal for exposed, sunny garden positions.
How often should I water nance?
Water nance every 14–21 days; highly drought-tolerant when established. Naturally adapted to seasonally dry tropical savannas with pronounced dry seasons. Established trees are highly drought-tolerant and rarely need supplemental irrigation beyond natural rainfall. Young plants need regular watering for the first 1–2 years. Overwatering is more damaging than drought for this species. The finger-test (or lifting the pot to feel its weight) beats a fixed weekly calendar because pot size, light, and season all change how fast the soil dries.
Is nance toxic to cats and dogs?
Nance is pet-safe. Byrsonima crassifolia (Nance) is not individually listed by ASPCA. It belongs to Malpighiaceae, a family with no widely documented toxic principles for companion animals. The fruit is extensively consumed by humans and wildlife with no reported toxicity. No known toxic alkaloids, glycosides, or irritant compounds are documented for this species. Reasonable caution is advised as with any unfamiliar plant, but it is not considered toxic.
What USDA hardiness zone does nance grow in?
Nance is rated for USDA zone 10–12 and RHS hardiness H1a. Outside that range, grow it as a container plant that overwinters indoors before the first hard frost.
