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.

Preferred mix: Poor, acidic, well-draining sandy or clay-sandy savanna soil

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.

Why nance needs this mix

Nance is a true acid-lover — it physically cannot take up iron above about pH 5.5, so an ericaceous mix is not optional, it is survival.

For the full picture on what makes up a good mix, see our guide to the main types of soil and potting media — it explains why each ingredient above behaves the way it does.

What goes wrong with the wrong mix

The wrong soil is one of the most common reasons nance struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:

Planting nance in standard compost or limey garden soil. Without an acidic (ericaceous) medium it will yellow and fail no matter how well you water and feed it.

pH — does it matter for nance?

This is the whole game: Nance needs pH 4.5-5.5. Test it, use ericaceous compost (and an ericaceous feed), and water with rainwater where you can to keep the pH from creeping up.

If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.

DIY mix vs a bagged one

Bagged ericaceous compost is the correct, easy base for nance; just open it up with bark and grit per the ratio above. Do not try to acidify ordinary compost by guesswork — it rarely holds.

Drainage and the pot

Containers are often easier than open ground because you control the pH completely. Use a pot with good drainage and an ericaceous mix; never let it sit waterlogged.

Top up or refresh the ericaceous mix yearly and test the pH each spring — it naturally drifts upward over time, especially if watered with tap water. When the time comes, our repotting guide for nance covers the timing and technique step by step.

Nance soil — frequently asked questions

What is the best soil mix for nance?

3 parts ericaceous (acidic) compost : 1 part composted pine bark or pine needles : 1 part perlite or coarse grit. Nance has evolved on acidic, peaty ground and depends on soil fungi that only function in acid conditions — raise the pH and it starves even in "rich" soil.

Can I use normal potting soil for nance?

Ordinary multipurpose or garden compost is far too alkaline for nance — expect classic yellowing, weak growth and a slow decline over a season or two. Bagged ericaceous compost is the correct, easy base for nance; just open it up with bark and grit per the ratio above. Do not try to acidify ordinary compost by guesswork — it rarely holds.

Does nance need a special pH?

This is the whole game: Nance needs pH 4.5-5.5. Test it, use ericaceous compost (and an ericaceous feed), and water with rainwater where you can to keep the pH from creeping up.

Should I buy a bagged mix or make my own for nance?

Bagged ericaceous compost is the correct, easy base for nance; just open it up with bark and grit per the ratio above. Do not try to acidify ordinary compost by guesswork — it rarely holds.

How often should I refresh the soil for nance?

Top up or refresh the ericaceous mix yearly and test the pH each spring — it naturally drifts upward over time, especially if watered with tap water. Containers are often easier than open ground because you control the pH completely. Use a pot with good drainage and an ericaceous mix; never let it sit waterlogged.
