For more details, check out our guide below where we delve into detail on the calculations. Using the example of a 10L sprayer on a 200m2 Hybrid couch lawn. If you need help working out rates for your lawn please reach out.

Start by calibrating your sprayer

This is just a fancy way of saying, learn how much water your sprayer puts out over a known area.

Top the sprayer up.

Spray the lawn in the way you would with chemical, ensuring a nice even application. For new users it is recommended to spray in 2 directions however 1 can also work if you’re accurate.

Ensure to time yourself whilst doing this spraying.

Spray for that amount of time into a bucket and measure the water used.

In this case say 6L used for the lawn.

So we top our sprayer back up to 6L for our application.

Wait for the test spray to dry.

Add PGR to the 6L of water needed for our lawn coverage.

For a 200m2 Hybrid couch lawn, apply PGR at the lower rate (10ml per 100m2) for the first application. You can always add more in future applications.

We recommend adding a liquid fertiliser like Lawn Play Enhance at the time of application to get best results of colour and growth.

Apply the Primo Maxx

Frequency of application

Primo Maxx inhibits leaf growth but unfortunately it eventually wears off. There are 2 recommended ways to apply the product.

  1. Applying on a regular schedule, for fast growing grasses like kikuyu this could be low rates weekly or higher rates fortnightly. For couch and other slower growing grass then a fortnightly or 4 weekly application would make more sense.
  2. The second method is more complicated but more scientific. This is using a terminology referred to as Growing Degree Days (GDD), This works on applications being made when the sum of each days average temperature hits 200. If using this method it is recommended to use a GDD Calculator.

We truly believe that Primo Maxx is a game changer for home lawn users, less clippings and a better lawns o please don’t hesitate to contact us, we would love every home in Australia to be using Primo Maxx to reduce green waste and improve lawns Australia wide.
