I'm ordering Cofea arabica (Coffee plant), Ficus retusa (Taiwan ficus), Mimosa pudica (Sensitive plant), and Ficus benjamina (Weeping ficus) seeds. I have never raised a plant from a seed so I was wondering how I should go about growing these plants. I guess I need to know how deep the hole needs to be, how many seeds per hole, do they need a hydroponic or greenhouse setup, and anything else that might be useful? Also, the Taiwan ficus can be grown in really amazing bonsai styles. Are the plants that imitate the bonsai just that big and old, or do they just plant a whole bunch of plants together to give the trunk that "forest of small thin trees" look?
