Hi,
Also, I have seen on the site that I should be mixing organic matter with my Bonsai soil. But I haven't found any sort of recipe of organic soil to Bonsai soil. Anyone have any recommendations?

Soil mix is an arcane science. Everyone does it differently. At our last club meeting that was the main discussion and everyone had different recipes, both what to mix and amounts.
In our area, central Alabama, we get long, hot days with lows to highs of 90F/30C to 105/41 for months and many of us use organics to add water holding capability. Some use plain potting soil, some old coffee grounds, some ground up pine cones, and some more specialized stuff.
So, take your pick. A consideration is climate in your locale. I do not think much water holding capability would be a good idea if you have a lot of cold, wet weather.
