Fertilising is an important part of lawn care in Perth to get right. For newly planted lawns first check by lifting the corner of a couple of rolls to see if your turf has developed a root system, then apply only small amounts of fertiliser (Knights Special Mix) every 6 weeks until the turf is established. The use of large amounts of fertiliser at once will only result in nutrient leaching and excessive growth.
Sir Walter Buffalo, Sir Grange Zoysia and TifTuf all require less fertiliser than older, less developed grass varieties to maintain a beautiful colour, especially less nitrogen. Newly planted lawn comes without a root system and needs a balanced starter food source. Lawn Solutions Australia has developed a product called Sir Launcher with additional trace elements and water crystals which can be applied when the turf is being layed.
Fertiliser should be spread at a rate of no more than 2kg (a standard 2 litre ice cream container) per 100m² per application. Lawns such as Sir Walter, Sir Grange and TifTuf should only be fertilised when a loss of colour or vitality is noticeable, however, do not forget the May fertilise. The May fertilise is extremely important to set your lawn up to keep it stronger through winter. The most accurate way to spread fertiliser is with a “Scotts” Handie Green Spreader. These are available from Lawn Doctor, along with the handy pails of specialised buffalo fertiliser.
NOTE: The use of large amounts of fertiliser at once will only result in nutrient leaching, excessive growth and is a waste of money.
