What is "overseeding" in turf management?

Overseeding is the practice of sowing grass seed directly into existing turf. This technique is commonly used to improve the density and health of a lawn by introducing new grass varieties that may be more resilient or better suited to current environmental conditions. Overseeding can also help fill in bare patches, improve color, and enhance the overall appearance of lawn areas that may have become thin over time due to wear, disease, or environmental stressors.

This method effectively enhances the lawn without the need for complete renovation, which would require removing existing grass. By carefully selecting grass types that are complementary to existing varieties, overseeding can promote a more sustainable and healthy turf environment. It is particularly beneficial during transitional seasons when soil temperatures are conducive to germination, allowing new seeds to establish before the growing season begins.
