Common Lawn Problems & Solutions

 

Fungal Diseases

Warming temperatures and moist autumn conditions can encourage fungal diseases in lawns. Look out for mottled brown patches, dead grass circles, or pink discolouration. If you spot these symptoms, it is important to diagnose and treat the issue promptly.

Solution: LawnPro Fungus Control effectively tackles various lawn fungal diseases.

 

De-Thatching Your Lawn

Thatch is the layer of dead grass clippings, stems, and roots that build up on top of the soil but beneath the grass. A thin layer (5-10 mm) is beneficial, as it helps retain moisture, insulate the roots, and prevent weed growth. However, too much thatch can block oxygen and moisture from reaching the roots, promoting fungal diseases.

Solution: If the thatch layer exceeds 10 mm, it's time to de-thatch. You can:

• Apply LawnPro D-Thatch to feed the microorganisms that break down the thatch.
• Use LawnPro Turfclean & Green + D-Thatch for an all-in-one solution to feed, weed, and de-thatch your lawn.
• Alternatively, use a sharp-tined thatching rake to remove the thatch manually. This is best done in early spring.

 

Aerating Your Lawn

Aeration improves oxygen flow around the grassroots and enhances drainage, especially before the cooler months.

Solution: In autumn and spring, use a garden fork to push about 10-15 cm into the lawn. Gently pull back to loosen the soil structure, improving the overall health of your grass.

 

Fertilising Your Lawn

Autumn and spring are great times to feed your lawn with essential nutrients, including potassium and phosphorus. These nutrients are critical for root development and frost tolerance. During the cooler months, you can also sweeten acidic soils to discourage moss and weeds.

Final Lawn Care Tips

• Weed Control: Since weeds are actively growing in autumn and spring, it's an ideal time for effective weed control.
• Fix Bare Patches: Repairing bare areas and thickening the grass will help protect your lawn from frost damage.
• Leaf Cleanup: Remove fallen leaves promptly to prevent them from suffocating the grass and harbouring pests or diseases.
• Mowing Height: Raise the height of your mower in late autumn to keep the grass at about 40 mm, providing insulation through the cooler months.
