aw...my bonsai

Seeds are tricky. Maybe try a little weeping fig or a ming araila instead? They're easy to find at a nursery and they make great indoor bonsai.

Start with something that is already thriving in the kind of environment you have available. Weeping figs are good. It takes a few years to turn anything into a decent bonsai, and they take a lot of care. I know, I used to have a lot. They all died when I got too tired to keep up with all the plants.
