What NPK 20-20-20 Means

A balanced, all-purpose fertilizer—also called 20-20-20 fertilizer or 20 20 20 fertilizer—supplying equal parts nitrogen (N), phosphorus (P) and potassium (K) for even vegetative growth, strong roots and steady flowering across vegetables, houseplants, ornamentals and lawns.

Balanced nutrition: Equal N-P-K (20-20-20) supports leafy growth (N), rooting & bud set (P), and vigor & stress tolerance (K).
All-purpose use: Great “all purpose fertilizer” for seedlings, transplants, herbs, greens, houseplants and ornamentals—ideal between bloom-booster cycles.
Flexible formats: Works as a water-soluble powder or a ready-to-mix 20 20 20 fertilizer liquid for soil, coco or hydroponics.

What is NPK 20 20 20? It’s a complete, balanced plant food delivering 20% nitrogen (for chlorophyll and foliage), 20% available phosphate (P₂O₅ for roots and blooms) and 20% soluble potash (K₂O for quality, color and resilience). Because the ratio is even, this 20-20-20 fertilizer is a reliable “do-most-things” feed that keeps growth steady without pushing plants too hard in any single direction.

Use for vegetables, flowers, shrubs, lawns and indoor plants when a general, balanced feed is desired.
Mix as directed by your product label; apply to moist media for consistent uptake. Can be used as a foliar spray where appropriate.
If your water is very soft or plants are heavy feeders, pair with a calcium-magnesium supplement for complete nutrition.

I’ve used a lot of fertilisers over the years, but this NPK 20-20-20 is hands-down the best value I’ve found. It’s properly balanced — unlike turf blends that are missing phosphorus — and works across my entire garden.

The results are amazing shinier leaves, more growth, and even new flower buds. The 20L size lasts forever and is way more affordable than buying small bottles

What plants is this fertiliser suitable for?

It’s designed for all plant types — from fruit trees, veggies & flowers to orchids, indoor plants & hydroponics. Whether you’re a home gardener or running a nursery, this is your go-to liquid feed.

Is this fertiliser safe for hydroponics?

Yes! It’s fully water-soluble and ideal for hydroponic systems. Provides balanced nutrition with zero clogging or residue.

How often should I apply it?

Use once a week in the growing season and once every two weeks in winter. For sensitive plants like succulents, orchids or bonsai — use at half-strength.

What makes this better than turf-only fertilisers?

Unlike turf fertilisers that often lack Phosphorus, ours is balanced (20-20-20) with full macro & micro nutrients — supporting roots, flowers, and fruiting, not just greening. It’s truly all-purpose.
