Frequently Asked Questions
When is the best time to overseed in New Jersey?
Aim for early autumn, specifically between late August and early October. The soil is still warm, which encourages quick germination, but the air is cooling down to reduce heat stress on the seedlings.
Do I need to remove the old grass first?
No, you should keep the existing grass as a foundation. Mow your lawn to a short height of about two inches and rake away thatch or debris so the new seeds make direct contact with the soil surface.
How much water do new seeds need?
Keep the soil consistently moist until the grass reaches a height of two inches. Lightly sprinkle the area two or three times a day rather than soaking it once, as tiny seeds dry out as quickly as a sponge in the sun.
Can I use a fertilizer at the same time?
Yes, applying a starter fertilizer is highly recommended. It provides the essential phosphorus needed for strong root development, giving your new grass a competitive edge against existing weeds.
How long should I wait before mowing the new grass?
Wait until the new blades reach a height of three to four inches. Make sure your mower blades are sharp to avoid tearing the tender seedlings, and only remove the top third of the grass height per session.
