The presence of certain weeds can somtimes give an indication of the growing conditions for your lawn. However, this selection is a bit of a mix. Typically one would expect violets in a shady area, clover in a lawn that is lacking nitrogen and sedge in a lawn that is poorly drained. Also, wherever turf grass is sparse there is an opportunity for weeds to thrive so it is not unusual to see a variety of weeds in a lawn that is not doing well.

Although nutrients can play a role, there are other factors that can affect lawn quality such as soil pH, soil compaction, height of mower blade and frequency of mowing, soil moisture levels and soil type, as well as the type(s) of grass growing in the lawn. If you are concerned about weeds in your lawn, I would strongly suggest you work with your local Penn State county extension to run some basic soil tests to check fertility and pH and to review your overall lawn management practices.
