How can buffalo lawn be dethatched without harming the runners?

[shmo]

Hi Community,

I have a buffalo lawn that’s just looking OK but it's becoming patchy and brown in some places with the grass dying off in others. It is spongy in places where the grass is looking good but as mentioned other areas are browning \ dying. This hasn't been an issue in previous years.

I thought that maybe I’ll try dethatching it for the very first time - the grass was laid some 10 years ago and has never been dethatched.

I’m wondering if dethatching is suitable for grass types like Buffalo? Surely the tines of the rake will just rip through the runners? What would be the best way to go about this process?

Thanks in advance for your advice.

Hi @shmo 

Hiring a dethatching machine would  be the best quickest bet as it is designed to take the back  breaking work out of it.

I hired a   lawn coring machine machine once and while  i had it  I knocked on all my neighbours places and  offered to  do there  yards to for $40 each this  brought my hire  cost down for every one i actually did 8 places and was in the position of giving  extra $10 back to each place I did as i wasnt after profit,

Thatch is a layer of dead organic matter, roots, and stems that accumulates within your lawn, often making it appear uneven and spongy. Dethatching, which removes this layer, is crucial for allowing air, water, and nutrients to penetrate the soil, preventing waterlogging and fungal issues. For buffalo lawns, which typically require yearly dethatching, using a specialised dethatching machine or carefully lowering the mower height can effectively remove thatch without harming the above-ground runners. Alternatively, a dethatching rake can be used for less severe buildup, while specialised machinery like scarifiers are ideal for thicker thatch layers or larger areas. After dethatching, proper cleanup and fertilisation are essential for lawn recovery.

Typically, the runner will be hard against the soil, and the majority of the thatch is above them, so it's important not to scarify so deep that you severe all the runners. Just to be clear, though, dethatching a Buffalo lawn that hasn't been done for ten years will leave it looking very sore and sorry for a few months until it recovers.
