Frequently Asked Questions
When is the best time of year to overseed in New Jersey?
You should aim for early fall, typically between late August and early October. The soil is still warm enough to encourage quick germination, but the cooler air temperatures prevent the new seedlings from wilting under the stress of a brutal sun.
Do I really need to use a starter fertilizer?
Yes, you should definitely apply a starter fertilizer when you put down your seed. These formulas are rich in phosphorus, which acts like a jumpstart for the roots to help them anchor firmly into the soil.
How much grass seed do I actually need to spread?
A good rule of thumb is to apply about 3 to 5 pounds of seed per 1,000 square feet for overseeding. If your lawn is looking particularly thin or neglected, you might lean toward the higher end of that range to ensure full coverage.
Is it necessary to aerate before I overseed?
Aeration is highly recommended because it punches holes in the soil that allow the seeds to reach deep into the earth. Without this step, many seeds just sit on the hard surface of the soil and get washed away by the first rain or snacked on by birds.
How often should I water the new seeds?
You need to keep the top inch of soil consistently moist, which usually means light watering two or three times a day. Once the grass reaches about two inches in height, you can gradually shift to a deeper, less frequent watering schedule to encourage deep root growth.
