Fertilising Your Plants
When, what, and how much to feed your plants. Understand NPK ratios and why less is almost always more.
Understanding NPK
Fertiliser labels show three numbers:
- N (Nitrogen) — Promotes leafy, green growth
- P (Phosphorus) — Supports root development and flowering
- K (Potassium) — Overall plant health
A balanced 10-10-10 works for most foliage plants.
When to Fertilise
Spring–Summer: Every 2–4 weeks with liquid fertiliser.
Autumn–Winter: Stop or reduce to once every 6–8 weeks at half strength.
Signs of Problems
Under-fertilised: Pale leaves, slow growth.
Over-fertilised: Brown tips, white crust on soil, wilting despite moist soil.
If you suspect over-fertilising, flush the soil thoroughly with plain water.
