How to grow
True tropical — outdoors only in zone 11 and the warmest 10b microclimates in Florida, ideally with wind protection. Everywhere else, it's a greenhouse or large-container plant. Cacao evolved as an understory tree, so it wants dappled shade, rich organic soil, and humidity. Never let it dry out completely.
Water & feeding
Consistent moisture is critical — think rainforest floor, not desert. Mulch heavily and water regularly; drought causes flower and pod drop.
Common problems
- Cold — anything below about 40°F damages it
- Fungal pod rots in stagnant, humid air (needs airflow)
- Mealybugs and mirids on stressed plants
- Pollination — tiny midges do the job, so avoid broad-spectrum sprays
Harvest
Pods ripen directly on the trunk and branches (cauliflory — showing off). Harvest when pods color up, then ferment and dry the beans if you're making actual chocolate. Most home growers stop at 'look what I grew' and that's a perfectly valid endpoint.
Nerdy fact: The genus name Theobroma means 'food of the gods,' and cacao was once used as currency in Mesoamerica — you could literally pay for things in chocolate beans. Inflation, presumably, was delicious.
