Here is another reason that you might not want to use a cheaper potting soil. I believe in recycling, you might say the potting soil instead of throwing it out. This potting soil is recycled and this is some of the cheaper stuff. You can see it's gray and has some dirt in it. I've been watering it with my water can to try to get some moisture in it. Well the water is coming out of the bottom right there is water standing on the top but I can take my hand and dig to right there and there's dry dirt. In other words a cheap potting soil doesn't absorb and retain moisture as well as an expensive one that has a lot more organic matter. Organic matter absorbs moisture and the more organic you have in your potting mix the more moisture it's going to absorb, the more it's going to retain and the quicker it's going to absorb it. So that is something to think about, over here I'm fixing to pot these Mexican honeysuckles in some premium grade recycled materials that are very dried but I'm going to add a little bit of water to it to try to get it started.
