Theobroma COCOA / CHOCOLATE TREE (5 seeds)

Cocoa tree is a small, evergreen tree from the Malvaceae family (formerly Sterculiaceae).
It is a tropical species native to Mexico, domesticated approximately 3,000 years ago, most likely initially for the production of an alcoholic beverage and later for the manufacture of chocolate.

Its foliage consists of large, oblong, and glossy evergreen leaves, evolving from a coppery red in the juvenile stage to a deep green at maturity.
These leathery blades, which can reach 30 cm in length, are supported by articulated petioles that allow them to orient themselves according to the forest canopy light.

The flowering presents a unique characteristic called cauliflory, where thousands of tiny flowers emerge directly from the bark of the trunk and main branches.
These delicate corollas, with shades of pinkish-white and yellow, bloom throughout the year in ephemeral clusters called floral cushions.

Its fruit, commonly known as a pod, is a voluminous, woody berry measuring 20 cm in length, resembling a rugby ball with distinct longitudinal ridges.
Its color changes during maturation, shifting from green or purple to orange-yellow or brick red depending on the variety. Inside, a white, tangy pulp surrounds about thirty bitter beans.

The cacao seeds, called beans, are brown, elongated, and highly fragrant.

Uses:

A Historical Heritage of Pre-Columbian Civilizations:

Cultivated for millennia by the Aztecs and Mayas, the cacao tree (Theobroma cacao) is an iconic species of tropical regions.
Following its discovery by European explorers, it became a global botanical subject.
Choosing Ethnoplants seeds means cultivating the very origin of cacao, from the development of the pods to the harvesting of the beans, within a preserved environment.

Tropical Architecture and Exotic Elegance:

With its lush foliage and unique flowering habit (cauliflory), the cacao tree is an exceptional ornamental plant.
It serves as a centerpiece for a conservatory, greenhouse, or sun-drenched interior, offering a unique graphic structure.
Ideal for enthusiasts wishing to recreate a tropical microclimate, it brings elegant verticality and an original jungle atmosphere to your botanical collection.

Germination and Sowing:

• The best time to sow the cacao tree is from June, when night temperatures are warm enough.
• Prepare pots with fine, moist potting soil, preferably with an acidic pH. Plant the seeds 1 cm deep.
• Press the soil delicately by hand.
• Water copiously during planting.
• Place the culture in a very warm and humid environment, ideally at a temperature of 35°C to 40°C. (It is imperative to maintain this high temperature to prevent the seed from rotting.) Use a greenhouse to accelerate germination.
• Germination is challenging and typically occurs 4 to 8 weeks after planting.

Very beautiful exotic plant. Culture and germination are relatively difficult and require constant heat. Non-roasted, untreated seeds.

Substrate Quality:

The cacao tree requires deep, fertile, and organic-rich soil with a slightly acidic to neutral pH for optimal root development.
The substrate must be perfectly draining to avoid water stagnation, while maintaining a loose structure for constant aeration. A mix of 60% leaf mold, 30% well-decomposed compost, and 10% volcanic sand constitutes an ideal environment.

Light Exposure:

This understory species requires shade, especially during its first years, to protect its fragile foliage from direct sunlight.
Filtered light, mimicking the natural ambiance of tropical forests, is crucial to avoid foliage burn and the drying out of young branches.

Climate and Hardiness:

With zero hardiness, the cacao tree does not tolerate temperatures below 10°C and perishes quickly in the event of frost, even superficial.
Its thermal comfort zone is between 20°C and 30°C, with stability essential to ensure the continuous formation of flowers and fruits.
Outside of equatorial zones, its cultivation requires a heated greenhouse or a temperate conservatory where atmospheric humidity remains above 70%.

Watering Needs:

Watering must be regular and generous to maintain constant humidity, without saturating the roots with excess water.
During hot weather, daily misting of the foliage is recommended to compensate for evapotranspiration and recreate tropical moisture.

Propagation Methods:

Propagation is mainly carried out by sowing fresh beans.
Cuttings of semi-hardwood stems and grafting are also practiced by professionals to clone productive or disease-resistant varieties.
These vegetative methods allow for trees that fruit faster than those grown from seeds, while retaining parent genetic characteristics.

Pests and Diseases:

Main pests include aphids, mealybugs, and thrips, which attack young shoots and flowers to suck the sap.
Cryptogamic diseases, such as brown pod rot caused by Phytophthora, may also occur in case of excessive stagnant humidity.
