Hello everyone,
My buffalo lawn is dying. There is one big empty patch and also at many places lawn is getting dry. I have tried beetle treatment, aerated lawn, lawn fertiliser etc... however, nothing worked unfortunately. Looking forward to receive your tips and solution. Please find the attached images for your reference. Thank you.
Hello @aapkahiren
Welcome to the Bunnings Workshop community. It's sensational to have you join us and thanks for sharing your question about your lawn.
It looks like your buffalo lawn is struggling, with a large bare patch and widespread dryness. Since you've already treated for beetles, aerated the soil, and applied fertiliser without success, other factors might be at play. One possibility is compacted soil, which can prevent water from reaching the roots even after aeration.
Using a wetting agent like Richgro Ezi-Wet or Yates Waterwise and deep watering in the early morning or late afternoon may help. Shade could also be a contributing factor, as buffalo grass tolerates some shade but struggles in heavily shaded areas. If trees or structures are blocking sunlight, trimming them back slightly may promote better growth.
Fungal diseases, such as brown patch, can also cause thinning and dry patches, especially if there are signs of mould or a distinct ring around the affected areas. If a fungus is suspected, a treatment like Yates Mancozeb Plus may be beneficial. Additionally, watering habits can impact lawn health; frequent shallow watering can cause roots to stay near the surface, making the lawn more vulnerable to drying out. Instead, watering deeply two to three times a week is recommended. If water is not penetrating well, applying a soil wetting agent may assist.
Soil health also plays a crucial role, and testing the pH can provide insight into potential issues. Buffalo grass thrives in a pH range of 6 to 7, so if the soil is too acidic, adding dolomite lime can help, while an alkaline imbalance may be corrected with sulphur or organic compost. To encourage regrowth in the bare patch, spreading a thin layer of sandy loam mixed with compost and keeping it well-watered should help stimulate new growth.
If the area isn’t recovering, replacing it with buffalo turf runners or rolls from Bunnings may be necessary. Even though you've already treated for beetles, it might be worth checking for other pests like armyworms or fungal gnats, especially by inspecting the soil at night. If you're still experiencing issues, let me know more about your watering routine and soil conditions so we can troubleshoot further.
