2 – Drilling holes in the bottom for good drainage:
This step is really important, because basil, like other herbs, hates to have its roots in really wet soil. The roots wil rot and the plant will die. The holes in the bottom will make sure that the water gets drained.
I use plastic soup pots, because this allows me to keep an eye on the moisture level inside the pot and also to watch the development of the root system.
