Overview
- Coverage on Oct. 11–12, 2026 stressed that October is the final practical time to overseed or repair bare patches before gardeners should wait until spring.
- Experts say check soil temperature and aim for about a two-week stretch above roughly 46.4–50.0 °F so seeds can germinate, noting cool‑season and warm‑season grasses have different soil heat needs.
- Sow seed shallowly (about the depth of three stacked coins), press seed into the soil for strong seed‑to‑soil contact, and keep the surface consistently moist but not waterlogged for days or weeks after sowing.
- Protect new seed from birds with netting or reflective deterrents and consider aeration to relieve compaction and prevent pooling; gardeners report some commercial mixes such as Gro‑Sure Fast Start can germinate in seven to 10 days but timelines vary up to about 14 days or longer.
- If you miss this October window, wait until spring to reseed, and consider using a starter fertiliser and follow‑up overseeding in spring to thicken thin areas and repair any failures.
