Winter Fertiliser Trials: Preliminary Update


According to preliminary results below from the 2012 Winter Fertiliser trials at Ozbreed, winter may be the most important time of year to fertilise for a green winter lawn. Autumn fertilising has always been recommended for a greener lawn in winter, and so far combined with winter fertilising, it is showing much better results for a greener lawn in winter.

Nara Native Turf responded the best to an application of winter fertiliser with a 2.25 rating rise compared to only an autumn application. It was also one of the best rated varieties with a winter fertiliser application, including Sapphire Soft Leaf Buffalo and Kenda Kikuyu.

The full report will be finished and posted here in spring.

Note: all plots below were fertilised in autumn with slow release fertiliser. The ones also fertilised in winter were at a heavy rate with the slow release fertiliser Elevate NPK:24-1-10 (500ml per half plot, 1000ml per full plot)
