Conseils de culture
Brazil nut trees depend on specific euglossine bees for pollination and agouti rodents for seed dispersal — intact forest ecosystem is essential.
Trees take 12-15 years to first fruiting and 30+ years for full production; they are one of the longest-term agricultural investments possible.
Fallen pods (ouricos) weigh 1-2 kg and fall from 30-50 m height — collect during the wet season wearing hard hats for safety.
