you have to go to a yellow tree than press the A button and it will ask you to slather the bark with honey then you`ll have to be patient and wait for it to shake then press A again when shaking and a Pokemon will appear.
You can use that for the golden trees to catch Pokemon or use the honey in the grass to make Pokemon appear
Use honey on a tree, it should come out or you can trade via the GTS website or you could use the all Pokemon cheat on action replay. Hope this helps :-)
