Are you about to go on a holiday this summer, but are concerned about coming home to an overgrown lawn? What if there was a way that you could slow down the growth of your turf? In this blog, we take a look at how you can use Plant Growth Regulators, like Primo HG before you leave.

Plant Growth Regulators (PGRs) are products that turf professionals and now home gardeners can use to help slow the growth rate of a lawn. They help slow the vertical growth of the grass. The grass then uses this energy to promote lateral growth, making your turf grow thicker.
When a PGR is applied, turf growth can be slowed for up to 4 weeks. At a higher application rate, it can be slowed for 4-6 weeks. It is best to first apply at a lower rate to help your turf build tolerance and then use a higher rate on your next application.
Increased lateral growth when a PGR is applied will encourage thicker, denser growth. PGRs will also help redirect plant energy to the root system, helping turf become more robust and resilient.
With all these benefits, the most appealing is the reduction in mowing frequency. This can help cut the costs for sports turf management, help free up weekends, or help you come home from a holiday without having to deal with an overgrown lawn!
Another advantage of having your grasses growth regulated while your away is that it gives the illusion that you are still home. If your grass begins to look overgrown, it can give potential thieves a tip-off that you are not home.

When using a plant growth regulator on a home lawn, we recommend using Primo HG (500ml) and Amigo (1L).


Because plant growth regulators help slow grass growth, they are recommended only during the warmer months when active growth is present. It is not recommended to use a PGR when grass is either entering into dormancy, is dormant, or is heading out of dormancy. This is due to your grass’s growth rate already being slow during this time.
