While your lawn is not typically in the growing phase during winter it is still a great idea to fertilise during the cooler weather to ensure it has all the nutrients it needs and to prepare for the warmer weather to come. Winter fertilisers are a bit different from fertilisers used at other times of the year – they contain higher levels of Iron to green up and strengthen your lawn over the cooler months. Winter fertilisers don’t typically contain any other trace elements and don’t usually have Phosphate in the mix.
Apart from that, your winter fertiliser should be applied in exactly the same way as at any other time of the year – always follow the manufacturer’s instructions, safety first, spread evenly to avoid fertiliser burn, and water in thoroughly (or apply right before decent rain is due).
The results you achieve from applying your winter fertiliser will vary depending on the actual temperature of the soil and how cold it gets at your place. The application will help to improve the appearance of the lawn and provide required nutrients but don’t expect too much sudden growth or for the application to turn around a lawn suffering from poor health – it’s still in the dormant phase.
A word of warning – winter fertilisers are high in Iron and can stain driveways, paths and hardscape features with drips of rust. If the fertiliser spreads to these areas, blow or sweep if off thoroughly before watering the area to avoid rust stains. You can also avoid this problem by taking extra care during application and applying the fertiliser when there is no wind to contend with.
July is the perfect time to apply fertiliser and then you won’t need to worry about it again until September. Get more lawn care advice on the Daleys Turf blog page.
