Summer is slowly drawing to a close and for those of us in the lawn care biz that means one thing: time for overseeding. A long hot summer of drought, diseases, lawn-damaging insects, and constant foot traffic can often leave a lawn looking brown and battered, barely clinging to life. Overseeding can give your lawn the resources it needs to rejuvenate itself over the cold winter months so that it can burst back into lush abundance next spring. Although it may seem simple, overseeding effectively does actually require a fair bit of science and expertise, which is why it is one of the many lawn care services offered by the specialists at Turf Shield. Here are a few valuable insights into this often overlooked but extremely important step in lawn maintenance.
At the most basic level, overseeding, or reseeding as it is sometimes called, involves spreading grass seed over already existing turf, particularly in larger areas where the turf has begun to grow thin. Overseeding is usually considered when the lawn has developed bare spots, areas that are thinning or patchy, or if it has suffered damage from drought, diseases or insects, but it is not necessarily suitable for all types of grass at the same times of the year. Cool season grasses, like Kentucky bluegrass, perennial ryegrasses, and fescues, tend to grow best when the air temperature is between 60 and 75 degrees Fahrenheit, and so overseeding in the late summer or early fall gives the seeds time to germinate and gives the resulting seedlings time to mature to the point where they can survive before the winter cold sets in.
In order to maximize effectiveness and achieve the best possible results, fall overseeding should be combined with lawn aeration. Soil that has become compacted by heavy foot traffic and general wear can prevent air, water and nutrients from reaching the roots of new grass seedlings. Core aeration, which extracts small plugs of soil from the ground, not only gives roots better access to these vital resources, but also provides better seed-to-soil contact, greatly aiding in germination and the growth of new seedlings.
Overseeding can thicken lawns and make them more attractive, but the process requires know-how, specialized lawn care equipment, and professional lawn care follow-through to achieve the best possible results.
