Lawn diseases and a good autumn feed

Milder temperatures and any rainfall and humidity during autumn can promote the growth of lawn diseases. Lawn diseases include brown patch, winter fusarium, dollar spot and anthracnose. Lawn diseases can be hard to diagnose as signs can be similar to that of other lawn problems such as damage from insect pests like porina and grass grub.

Common lawn disease symptoms include areas of small discoloured, brown, dead or dying patches in the lawn. Lawn diseases can spread and reoccur year after year, so it’s important to get them under control and keep your lawn looking fantastic.

Here’s how to help reduce lawn diseases:

  • Mow regularly to prevent a build-up of thatch and remove clippings from the lawn.

  • Water only in the mornings, to allow the lawn to dry off during the day.

  • Aerate or core your lawn to improve drainage.

  • To control lawn dollar spot and rust diseases, use a fungicide like Yates Fungus Fighter Fungicide, which contains an effective broad spectrum systemic fungicide with both curative and protective action. Yates Fungus Fighter can be easily applied over affected lawn areas in a watering can.

  • Keep your grass well fed and apply a potassium rich plant food like Yates Thrive Natural Sulfate of Potash in early April. Potassium is a nutrient that helps strengthen the lawn so it’s better able to resist disease infection and cope with the cool winter weather. Apply at 50 g/m2 and then water in well.

Did you know that Yates Thrive Natural Sulfate of Potash also contains sustainably sourced seaweed and is a certified organic input by BioGro NZ?
