Step-by-Step Growing Guide
Cacao (Theobroma cacao) is a tropical understory tree requiring year-round temperatures between 65–95°F, high humidity (70–100%), and protection from direct afternoon sun — it is truly one of the most climate-specific crops on earth. It grows only between 20 degrees north and south of the equator. Plant in deep, well-drained, humus-rich soil with a pH of 6.0–7.5; organic matter is critical. In true tropical climates, plant in filtered light under a nurse tree canopy. Water frequently — cacao needs consistent moisture but not waterlogging. Apply balanced fertilizer monthly during the growing season and potassium-rich fertilizer as pods develop. The tree is cauliflorous: flowers and pods grow directly on the main trunk and large branches, not on new shoots. Hand pollination by midges occurs naturally in tropical environments but may be needed in cultivation. First harvest typically occurs at 3–5 years. In temperate climates, cacao can be grown as a novelty greenhouse plant but will not fruit without specialized conditions.
