When it comes to managing weeds such as dandelions and crabgrass, one of the most important aspects is maintaining a thick, full turf. This has to do with weeds being opportunists that seek out bare spots on the lawn and quickly take over. If you notice areas of the lawn thinning, have a reputable service overseed the lawn with quality seed designed for insect, drought, and disease resistance.
The best time to do this is in the spring or late summer and early autumn, with the seed lightly raked into the soil and then kept moist in the days prior to germination. Keep in mind that the soil should be at a neutral acidity level of pH 7 for optimal growth. Also realize that, while many weeds thrive in compacted soil, turf grass requires looser soil. If necessary, aerate the soil before seeding.
A final tip is to keep grass between 2 and 3 inches high. This not only keeps any emerging weeds in shade, but it encourages increased chlorophyll production and stronger root structures.
