Fertiliser and the right amount - how do I know?

Fertiliser is food to your lawn; too little and it starves, too much and you won't see it at its peak either. If your keen on looking after your lawn then getting a handle on fertilising is important. There are a few tell tale signs with your lawn to let you know if it needs fertlising. 

Too much fertiliser or not watered in properly can create a fertiliser-burn effect on your lawn. Lawn fertilisers come in many varying types and blends. Just take a look down one of the aisles in some of the bigger nurseries and you can get confused as to what may be the best for your lawn. Going back to basiscs, lets look at your lawn being like any ordinary plant. It takes in nutrients and air through the soil and sunlight through the leaves for photosynthesis where the conversions to sugars and energy takes place.  With everything in balance this happens well and the plant will thrive and what we want to do is help keep this process at its optimum.

So in keeping that optimum level of nutrient input for your lawn you can look out for a few tell tale signs when its lacking;

- if you've got pets the green patch left from urine is an obvious giveaway. Urine containing urea is high nitrogen-charged and sometimes you're left with a burnt patch and afterwards a more lush-green area appears.

- this can also be noticeable next to pathways where nutrients - from blown in dust and particles will wash off the path and be more concentrated next to the edges.

- Seed-heads on the grass when it starts to go  into stress, and a yellowing, thinned out appearance, not related to the seasons is also a giveaway that your lawn needs a feed. Clover invading parts of your lawn is also a good sign that your fertiliser regime is wanting as it struggles to grow when nitrogen levels out at a level where your lawn is doing well.

Most Australian lawn types; warm-season grasses that include Eureka Kikuyu, Nullarbor Couch and  Sir Walter Buffalos are able to be fed on a regular basis at around six-weekly intervals and it helps to mix up the applications. 

If you talk to any sports-turf curator; golf, stadium or bowling green professional or a turf farmer they will tell you about mixing it up between organic manures and compost top dresses through to fertliser mixes that are usually high in NPK. The NPK (Nitrogen, Phosphorous and Potassium) levels are usually the most critical components when it comes to fertilers mixes and you will normally find these elements clearly marked on a fertiliser label.

So Where to from here?

Its best to mix it up between organic and synthetic fertilisers every six weeks or so for a home lawn and it should reach its peak in no time. Make sure you read the label; but generally 20 grams per square metre is recommended in most cases so two kilograms will do an average 100 square metre lawn. Make sure you water as watering is probably the most important so if you don't have an irrigation system, apply before a shower of rain or hand water in well after application.
