Summer 2024 turned out to be a hot and dry one and in turn very difficult for the turf. If you are undecided about whether to aerate and seed, this is the year to do it.
Core aeration is a great practice to do on a regular basis (especially after such harsh summer weather). Aeration will help to break up the compacted soil. This in turn allows better water and fertilizer penetration into the soil. The benefit for the lawn is stronger root development (and less thatch).
Overseeding along with the core aeration will incorporate stronger grass types, such as turf type tall fescue, into the existing lawn. This grass type is more tolerant of summer weather, is insect and disease resistant and is a beautiful dark green color. Many lawns in our area are primarily bluegrass, fine fescue and perennial rye grasses. Unfortunately, these types of grasses are not very resilient to hot dry conditions, insect activity or disease. Once upon a time, these were the “go to” grass types (sold as Lehigh Valley Blend, Del-Val Blend, etc…) but as our knowledge and science progressed, the turf type tall fescues have become the most suitable grass type for longevity, resiliency and color.
Core aeration and seeding is a process and should be done for at least 3 years (or longer) to fully incorporate the turf type tall fescue varieties. Eventually the turf type tall fescue will begin to spread but this does take some time. Additionally, it is important to remember that results from core aeration and overseeding are not noticeable until late spring the following year (usually after a few mows). It takes time for the young grasses to develop good roots and mature to the point where they are noticeable.
Proper watering will ensure the best germination and expedite the process. Fall weather is generally the best for germination of new seed but can be affected by heat, lack of rain and other negative factors. On a final note, as tempting as it may be, do not remove the cores of soil after aeration. The soil will eventually be washed back into the holes, filling them in.
Germination of the new seed will be most obvious in the core aeration holes. The seed will usually wash into the holes and come up like plugs. That is why aeration and seeding if great for incorporating stronger grass types but not intended to repair large areas.
Currently many lawns are very patchy due to the bluegrass not recovering well from this summer’s drought. If you have any questions or would like and estimate for core aeration and seeding this year, just give us a call at 610-965-4452.
