Adding Potassium to ‘Winterize’ Your Lawn

To help your lawn function at optimum capacity it needs a mix of Potassium and other nutrients to create a healthier lawn that is more resilient to disease, drought and temperature change.

At certain times of the year, some nutrients can be more important than others. During autumn when temperatures are starting to cool, there is one nutrient that needs to be freely available for your grass to absorb to help prepare it for winter and that is potassium! Most of us know about nitrogen and its ability to provide a quick green colour and leaf growth, but now is the time to boost the health of the entire plant, and this is where potassium comes in.

What is potassium?

Potassium is a chemical element (K) which was originally derived from potash. Your lawn would struggle to grow without it, lacking in strength and suffering from yellowing of the leaf.

What does potassium do for your grass?

Potassium functions within the cell of the grass and provides strength to the whole plant. It aids the internal processes including photosynthesis, respiration and protein production, therefore creating thicker cell walls.

If you have been fertilising your lawn with a balanced slow release granular fertiliser during the year and including autumn, then a specific winter fertiliser will normally not be required and the potassium levels in your soil should be adequate. Cool season grasses continue to grow strongly throughout winter, so there can be times where a ‘winterizer’ fertiliser with a higher potassium component or where an application with potash might be required, particularly in the more southern Australian states.

If you haven’t fertilised this season, now is a great time to do so. A good quality slow release fertiliser will contain all the nutrients your lawn needs, including potassium, and will last for up to 12 weeks.
