Do I need two cacao plants to produce fertile beans?
Chocolate producing fruit? (Same question, different plant).
Very interesting reading......looks like you needs minute flies to fetilize rather than simply 2 trees.
But I could be reading it wrong.........

The native cacao tree also depends on minuscule flies, attracted by the overripe pods that fall to the ground and rot around its base. The flies require large pieces of moist tropical detritus (such as rotting cacao pods) to carry on their own life cycle; while thus occupied, they pollinate the tree's small flowers, which develop into the next generation of pods. Because of that natural history, cacao is much more likely to be pollinated in a forest with a moist, messy understory than in a commercial plot cleared or raked by human tools.
