September Lawn Care Tips for a Healthy Autumn Garden in South Hams

As summer fades and autumn begins, September is one of the most important months for lawn care. The cooler temperatures and regular rainfall make it the ideal time to repair summer damage and prepare your lawn for the months ahead. At Terraform Gardens, we provide professional lawn care in the South Hams and across South Devon, helping homeowners and businesses keep their lawns green, healthy, and inviting all year round.

At Terraform Gardens we use professional Hayter battery mowers

1. Mowing and Edging

Grass growth slows slightly in September, but mowing is still essential. Keep the mower blades sharp and avoid cutting too short—around 3–4 cm is ideal. Regular mowing and neat edges make a noticeable difference to the overall appearance of your garden.

2. Aeration for Healthier Lawns

Compacted soil is a common issue after summer. Aerating the lawn in September allows water, nutrients, and oxygen to reach the roots. This is particularly beneficial in clay-heavy soils found in parts of South Devon. For heavily used lawns, professional hollow-tine aeration gives the best results.

3. Autumn Lawn Feeding

Applying an autumn lawn feed in September strengthens roots and boosts resilience against frost and disease. These fertilisers are lower in nitrogen but higher in potassium, keeping lawns greener for longer and setting them up for strong spring growth.

4. Reseeding Bare Patches

If your lawn has worn or bare areas, overseeding in September is highly effective. The warm soil and autumn rainfall provide the perfect conditions for seed to establish. Pairing overseeding with aeration encourages thicker, healthier growth.

5. Moss and Weed Control

Moss thrives in damp, shady areas as the nights lengthen. Treating moss now helps prevent it from spreading across the lawn. Tackling weeds in autumn also reduces competition for nutrients and sunlight, helping your lawn thrive.

6. Scarifying for Long-Term Lawn Care

Lawns that suffer from thatch build-up can benefit from scarifying in September. This process removes moss and dead material, encouraging fresh growth. While it may look harsh at first, it results in a stronger, lusher lawn by next spring.
