At this time of year, late spring – early summer, a common concern is the popping up of seed heads in your lawn.
They typically grow from the green stem of a lawn leaf and the colour of the seeds can range from purple to brown to white.
Are lawn seed heads a problem?
The majority of plants flower at least once a year. So, this is just Mother Nature taking its course as part of your lawn’s natural survival mechanism in response to change. In this case, sudden hot weather or lots of rain. If your lawn is only going to seed during these sudden changes, then you have nothing to worry about.
Most lawn varieties are now hybrids – producing a sterile offspring. Lawn seed heads on the DNA Certified Sir Walter Buffalo, Eureka Kikuyu, Nullarbor Couch, or newly developed lawn varieties are sterile. This means they will not spread into other areas of your garden and grow from the seeds.
Getting rid of seed heads
If your lawn is healthy, the seeding should stop after 2-3 weeks on average. If the seed heads continue to pop-up, it may be a sign that your lawn is stressed. This could be a result of a lack of nutrients – fertiliser or simply not enough water. If so, then follow these steps:
Mow the tops of your lawn leaves every 5-10 days to remove the seed heads.
Make sure that your lawn is receiving an adequate amount of water by checking the soil moisture. Also check that your watering system is working adequately.
To check soil moisture, try the footprint test (see below).

Top dress your lawn with clean river sand – top dressing sand can be purchased from your local garden centre.
Once all these steps have been completed, your lawn seed heads will slowly vanish. If they are still appearing after a couple of weeks’ time and you have followed the recommended steps – it may be time to talk to an expert! Contact The Turf Farm office, via phone or email and we can assist you!
The footprint test
Walk along the grass. If the lawn leaves don’t bounce back, this indicates that there are low levels of moisture in the blades and it needs more water. If they bounce back, then your lawn is hydrated & happy.
