Seasonal Fertilising Tips for South East Melbourne
Spring (August – November)
This is the most important feeding period. Grass is waking up and needs nitrogen for strong leaf growth. Apply twice in spring for best results.
Summer (December – February)
Focus on potassium to help the lawn survive heat stress and drought. Avoid high-nitrogen fertilisers during extreme heat.
Autumn (March – May)
The second most important season. Build strong roots with high-potassium fertiliser to prepare for winter and next spring.
Winter (June – August)
Grass grows very slowly. Usually no need for granular fertiliser. A light seaweed tonic is enough.
Pro Tips from Small Brother Team
- Always water fertiliser in lightly after application
- Never fertilise before a heatwave (above 35°C)
- Use slow-release fertilisers to reduce burn risk
- Apply on a calm, dry day for even coverage
- Core aeration before fertilising dramatically improves results
