How Often Should You Slash a Vacant Block in Melbourne?
Vacant blocks can become overgrown quickly, especially after rain followed by warm weather. If left unmanaged, long grass and weeds can create a fire hazard, attract pests and make the property look neglected.

There is no single schedule that suits every block. The right slashing frequency depends on:
- Grass growth rate
- Season
- Rainfall
- Property size
- Council expectations
- Whether the block is near homes, roads or other assets
- Whether weeds are present
As a general guide, many vacant blocks benefit from slashing every 6–12 weeks during active growing periods. In the lead-up to summer, property owners should inspect the block more regularly and arrange slashing before grass dries out.
Some councils give specific fire prevention guidance. For example, Cardinia Shire advises that grass on vacant properties should be maintained to a maximum height of 10cm to reduce fire impact.
