Description
TRIPLE BOOST Fertiliser 20L is a liquid NPK fertiliser containing nitrogen, phosphorus and potassium, in the bulk drum. This is the trade pack – built for people applying through a boom or a large sprayer across an area, not a watering can across a bed.
Why the 20L
At $189.20 the drum works out at $9.46 per litre, against $17.60 per litre in the 1L bottle – a saving of just under half. For turf contractors, landscapers, growers and acreage owners running a regular feeding program, the drum is the only size that makes economic sense.
If you are feeding a suburban block, the 5L will almost certainly suit you better. Liquid fertiliser is best used within its shelf life, and 20 litres is a lot to work through on one lawn.
What it does
Nitrogen drives leaf and shoot growth. Phosphorus supports root development, flowering and fruit set. Potassium goes to overall plant hardiness. As a liquid it goes into solution cleanly and is taken up without waiting on soil moisture to break down a granule.
Suitable for turf, pasture, horticulture and large-scale ornamental plantings. Always follow the dilution rate on the label.
