Should I Use Liquid or Granule Fertiliser?
Both are great, but they have different purposes. So one type may be better suited for your goals.
Put simply, liquid fertilisers are fast acting, but short lived. You will likely see improvement 4-24 hours after application, but the benefits will only last 2-4 weeks. They give a beautiful even colour if applied correctly and are great for colder weather.
Granule fertilisers are usually slow or controlled release. They last a lot longer, most average around 6-8 weeks, some 10-12 weeks and a rare few will even last 6 months. In Perth conditions it granule fertilisers can loose effectiveness when the cold winter weather hits.
If you are looking for long lasting results use granule fertiliser, if you want a quick colour boost or a good option for winter use liquid fertiliser?
How much fertiliser should I use in WA conditions?
It is very common for WA lawn lovers to over fertilise and to over water (click here to find how to correctly water).
The simple advice is to follow what the manufacturers label says. If you are using a new product for the first time and the label says “30-50g per m2” I would apply 40g per m2 as my first application and adjust for future applications based on how my first application went.
