How to get rid of wintergrass without damaging lawn?

[varusman]

 

i have quite a situation with wintergrass weeds. I’ve purchased oxafert pre emergent herbicide so will be applying this every 3 months to address the issue for next year.

my main question is should I be removing the current weeds given that every time I do it pulls up the underlying grass (sir Walter buffalo)?

any other tips to revive this lawn?

Thanks Jacob that’s helpful. 

There’s no depression I must have just set it to low (I’ll set it to the highest setting next time). 

Can I use seasol buffalo lawn spray on fertiliser instead? I’ve been using oxafert on the rest of the grass.

Hello @varusman 

If you've been using Oxafert just recently, please do not use any other fertilizer on the lawn to prevent damaging the roots. Too much fertilizer will burn the roots of the lawn, and they will turn brown and die off. 

If you need further assistance, please let us know.

I’ve been using oxafert on the rest of the grass not the newly laid turf (I haven’t fertilised this since laying it in November with starter fertiliser). 

can I use the seasol on the new turf now?

The original Seasol version is fine to use on all of it as it's not a fertiliser, @varusman. Just don't use the lawns version as it is a fertiliser. You can only use one fertiliser at a time. For the unfertilised new Buffalo area, you can use the Seasol Lawns version, or the Munns Professional 2.4L Green Dominator Lawn Fertiliser Hose-On would be fine.
