The real test is how your plants are growing. If you are satisfied with their growth and condition, you don't need to change anything. If you aren't satisfied you need to figure out what you need more or less of (growth, color, runners, flowers, seeds, success with difficult plants, etc.) and then figure out what is holding you back from getting it.
