The weed creeping over lawns like a bad carpet
Owner of Caloundra Garden and Pet Supplies
THE Creeping Indigo weed is a legume that fixes nitrogen into your soil and has a long tap root that opens up heavy clay soils.
The bad bit is that it has been creeping into our lawns like a carpet, covering everything.
The stems lay flat and don’t get cut by the mower while the seeds get cut off and spread throughout the lawn. To control it manually, soak the soil first, pull out the runners and then pull out that tap root.
As it is a bit harder to kill than some weeds, and you want to use a herbicide, fertilise lawn first with a high nitrogen fertiliser such as CK 88, and a light dusting of Dolomite.
This will get the weed growing with lots of leaves, and more surface area for the herbicide to stick to. As it is growing faster is will absorb the herbicide better.
The CK 88 will also have the turf growing quickly to fill the gaps where the weeds were. Do not mow for a week.
For couch grass, spray with a herbicide such as Searles Lawn Weeder, adding some Spredmax wetter.
Spray again in a week. The same goes for Buffalo lawn, but instead use Buffalo Master herbicide with some Spredmax.
