Hold off on the Fertiliser – Just for now!
Author: Stefan Palm Date Posted: 1 March 2018
As most lawn buffs will know, lawn needs fertilising during Autumn for a number of reasons. It helps maintain better winter colour, increases cold weather hardiness and of course it builds up the lawns nutrient reserve so that it has some fuel in the tank
As the days become shorter and nights cooler, traditional summer active lawns (couch, buffalo and kikuyu) change from producing rapid leaf growth to a new and critical phase where they increase considerably the number of new rhizomes they develop. In essence the more rhizomes you have on each plant the thicker the lawn.
But, don’t be in a hurry to apply fertiliser just yet. A heavy application of fertiliser now is likely to produce heaps of grass but at the expense of rhizomes. If the lawn is making active growth but the grass looks a little pale, consider applying a very light application of nitrogen that would typically be found in a certified organic fertiliser such as Paul Munns Organic Lawn Food.
The best time to apply Autumn fertiliser is around early April. At this point, the lawn still hasn’t gone into winter dormancy but it’s about to. This means it will use the nutrient to improve colour without resulting in excessive blade growth. It will also store a fair amount of it ready for spring. In the coming weeks, I’ll post a blog on what to use and when so stay tuned!
