Bulk fertiliser prices and pack sizes
Buying fertiliser in bulk lowers the cost of every litre of mixed feed and means fewer orders to manage. Every bulk pack on this page is priced online, so you can compare products and order straight away without waiting for a quote.
Our bulk fertiliser range
- Bulk liquid fertiliser: 20 L All Purpose NPK 20-20-20 liquid plant food with micro nutrients. A balanced feed for vegetables, fruit trees, ornamentals, lawns and turf.
- Water-soluble powder: 20 kg NPK 20-20-20 with micro nutrients. It mixes straight into water and is the most economical way to buy a balanced NPK fertiliser.
- Flowering and fruiting: NPK 4-18-38 + calcium and magnesium in 10 kg and 20 kg, for tomatoes, capsicums, strawberries, fruit trees and cut flowers once they start budding.
- Bulk hydroponic nutrients: 20 L two-part A & B with calcium and magnesium built in, for commercial hydroponic systems.
- Kits: the Commercial Pro Fertiliser Bundle pairs 20 L All Purpose with 2 L Cal-Mag and the Precision 1L Sprayer.
Made for commercial and large-scale growing
Our bulk sizes suit market gardens and small farms, plant nurseries, landscapers and garden maintenance crews, turf and sports ground managers, hydroponic growers, and home gardeners with big gardens who want the lowest cost per litre.
Bulk fertiliser prices
Prices are listed on every pack above, with the cost per litre of mixed feed shown where it applies. Concentrates go a long way, so compare bulk fertiliser on the cost per litre of mixed feed rather than on pack price alone.
Buying by the tonne, on a regular schedule or for resale? Our wholesale accounts are set up for ongoing supply, and we’ll quote on your volumes. Call (02) 9053 1426 to talk it through.
Choosing the right bulk feed
Most growers run a balanced NPK 20-20-20 through the growing phase, then switch to NPK 4-18-38 once plants start flowering and fruiting. Hydroponic growers use the two-part A & B, which already includes calcium and magnesium. If you’re not sure which suits your crop, check our NPK fertiliser and hydroponic nutrients ranges, or give us a call.
