Overseeding Mistakes West Sussex Homeowners Should Avoid (So Your Seed Actually Grows)

Sown seed that never takes? Avoid these easy errors and get thicker grass in weeks.

Overseeding is the fastest way to refresh a tired lawn in Chichester, Emsworth and Arundel—but only if you get the basics right.

Common mistakes (and fixes)

• Skipping prep. Seed needs contact with soil. Scarify to clear thatch and open the surface.
• Wrong timing. Aim for early autumn or mid-spring when soil is warm and moisture is reliable.
• Too much seed. Crowded seedling roots compete and fail. Stick to 20–35 g/m² depending on blend.
• No topdressing. A 3–5 mm layer of loam/sand helps germination and evens tiny dips.
• Letting it dry out. Water little and often for 2–3 weeks; then reduce frequency and water more deeply.
• Mowing too soon. First cut once new grass hits ~6–7 cm; only trim the tips.
