Perth's sandy soil loses nutrients quickly. Without regular feeding, leaves yellow, growth slows and plants fade. A simple feeding plan keeps them strong all year.
What plants need
- Nitrogen for leaf growth.
- Phosphorus for roots and bulbs.
- Potassium for flowers and disease resistance.
- Calcium, magnesium and sulphur for balance, plus trace elements.
Organic or inorganic?
Both work. The key is moderation, as overdoing either harms the soil. Avoid feeding lawns with sulphate of ammonia alone, since over time it acidifies sandy soil. Combining organic matter with a slow-release fertiliser keeps nutrients steadier between feeds.
What works in Perth
- Add trace elements once a year.
- Use a low-phosphorus fertiliser made for natives, as many Australian natives are sensitive to phosphorus.
- Dig compost or aged manure into beds before each growing season.
- Water deeply after feeding so the nutrients reach the roots.
A simple seasonal plan
- Autumn: add compost and check the soil pH.
- Winter: build soil structure with organic matter.
- Spring: feed with a slow-release fertiliser and trace elements.
- Summer: mulch to protect the soil from heat and moisture loss.
