White Cacao/Balam

Description

Description:

White Cacao (locally known as Balam) is a beautiful understory, evergreen tree growing to a maximum height of 25-30 meters in its natural forest habitat.   More commonly growing from 3-8 meters this understory species offers dappled shade and year-round greenery with opposite, papery leaves reaching 15-35 cm long. Delicate purple flowers emerge in small clusters along branches and the trunk, giving way to cone-shaped, yellowish fruits (8-12 cm long) that naturally detach when ripe, revealing 30-50 calorie-packed seeds encased in sweet, mild pulp—perfect for fresh snacking, juicing, or even crafting traditional Maya-style foamy beverages.  Flowering peaks from July to September in the central Amazon, with fruits ripening March to November.

In agroforestry applications White Cacao will have a tall, narrow growing habit with overall widths being 2-4m (6.5-13 ft).  In the wild, canopy widths of 4-6m are common under ideal conditions.

Key Characteristics:

• Native Range: Native to the lush understories of Central and South American rainforests, from southern Mexico through the Amazon basin in Brazil, Colombia, Ecuador, Peru, and Bolivia.

• Height and Width:  Standing 3-8 meters tall in cultivation with a slender, narrow crown, it can soar to 25-30 meters in its natural forest habitat, offering dappled shade and year-round greenery with its opposite, papery leaves reaching 15-35 cm long.

• Elevation:  Sea level up to 1,000 meters.

• Growth and Care: Thrives in well-drained, fertile soils with full sun exposure. It prefers warm, humid climates and is sensitive to frost. Regular watering during establishment and occasional pruning promote healthy growth.

Often used in shaded coffee plantations or mixed agroforests where it is intercropped seamlessly with companions like banana or citrus.

Culture:

1. Climate

• Temperature:  Thrives in hot, humid tropical climates.  Optimal temperature range: 20-30°C (68-86°F). It can tolerate brief dips to 15°C (59°F) but is sensitive to frost.
• Rainfall:   Water regularly, mimicking tropical rainfall patterns, but ensure good drainage to avoid fungal issues.  Keep soil consistently moist but not soggy; maintain even moisture, especially during establishment.  Mulching around the base of plants retains moisture and helps to moderate soil temperature.
• Humidity:  Requires high humidity (>70%) to support lush growth.

2. Sunlight

• Prefers partial shade to dappled sunlight, mimicking its understory habitat.
• Avoid direct, intense sunlight, which can scorch leaves; 50-70% shade is ideal, especially for young plants.
• In agroforestry systems, plant under taller trees (e.g., bananas or timber species) for natural shading.

3. Soil

• Soil Type:  Well-drained, fertile soils rich in organic matter are essential. Balam prefers loose, alluvial soils typical of lowland situations. Avoid compacted or poor-draining soils to prevent root rot.
• pH Level: Slightly acidic to neutral with a preferred range of 5.5 to 6.5.
• Fertility:  Grows best in fertile, well-drained soils rich in organic matter.

4. Watering

• Watering Schedule: Keep soil consistently moist, especially during establishment. Regular watering is crucial in drier periods but ensure excellent drainage to avoid standing water.
• Drought Tolerance: White Cacao is not considered a drought tolerant tree so planting it in an area where natural moisture is present year-round is essential.  To aid in moisture retention consider applying a thick layer of mulch around the base of the tree or planting in an area that receives shade during the hottest part of the day.  This species lacks a deep taproot and, as such, has moderate to low drought tolerance.  Young trees are especially susceptible to dry conditions.

5. Planting Location

• Site Selection: Choose a site with good air circulation, well drained but moist soils and protection from strong winds especially when young.  Year-round moisture is essential so planting in a low area or along waterways helps.  Can survive short periods of drought.

6. Care and Maintenance

• Pruning: Minimal pruning is needed, mainly to remove dead or damaged branches and maintain the tree’s shape. Pruning can also encourage a denser canopy.
• Pests and Diseases: Balam has a number of pests and diseases that affect it.  Many of the insect pests include sap-sucking insects that create a mutualistic association with ants that “farm” the insects for honeydew.  Many of the diseases are of a fungal nature that may render leaves unsightly for a short period of time.  Planting in an area that receives some wind to help dry leaf surfaces will reduce fungal infestations.
• Fertilization: In commercial growing operations applying a balanced fertilizer during the growing season can support healthy growth, especially in nutrient-poor soils.  In the field, a soil rich in organic matter will promote growth while retaining soil moisture.

Faunal Associations:

• Rainforest Ecosystem Role: In its native range (sea level to 1,000 meters), T. bicolor is a hub for biodiversity, supporting pollinators, frugivores, and decomposers in shaded understories or agroforestry systems (e.g., with coffee, bananas, or citrus). Its high-fiber, caffeinated seeds and sweet pulp make it a valuable food source for wildlife, while its flowers sustain specialized pollinators.

Monkeys, Agoutis, and many bird species are attracted to the sweet fruit produced by White Cacao.              Birds, bats and a host of insect species are known pollinators when in flower.

• Agroforestry Benefits: In cultivation, T. bicolor fosters beneficial insects (e.g., midges, predatory wasps) that regulate pests and enhance pollination for nearby crops. Its shade tolerance makes it ideal for mixed systems, where it attracts fauna that contribute to ecosystem stability.
