I can understand that. Do you have a source in Brazil for quality soil?
Brazil has the biggest Japanese population (first, second and third generation) outside Japan, and most nurseries are owned by Japanese bonsai growers.
Usually we can't bring soil or fertilisers from abroad, but Japanese descendants can, and they do.
So the answer is yes, I can buy the good stuff here. It's expensive, but less than buying it from Canada I guess.
Last november I managed to bring in a big pack of BioGold from Tokyo/Saitama among other bonsai goodies, and it will last for a while, I hope.
