Connect the Fertiliser Spray Mixer to your hose and quickly and conveniently dispense commercial fertiliser onto your lawn or garden. The easy-to-use trigger spray is ideal for those who suffer from arthritis and are unable to use a pump-style bottle.

Not suitable for low water pressure or use with water tanks, requires minimum 50psi to operate.

Tired of ill-fitting connections to pre-mixed fertiliser spray bottles? Due to strong demand, we've introduced the Fertiliser Spray Mixer so you can enjoy a reliable connection between your Hoselink-fitted hose and the Fertiliser Spray Mixer - no more leaky fittings!

How to use the Fertiliser Spray Mixer

  1. Add concentrate to the bottle, no pre-mixing required. *Please ensure you read the instructions on the fertiliser bottle as this may vary.*
  2. Set dilution ratio by turning the selector dial until the desired number is aligned with the brass knob on the side of the dial.

    To work out the setting required for your own brand of fertiliser use the table below:

     
  3. Attach the Mixer to your Hoselink-fitted hose using the included Accessory Connector.
  4. Turn water flow on. Squeeze the trigger and spray on to your lawn or garden as required.

Installing the flow reduction

  1. Unscrew the bottle and remove the filter from the base of siphon tube.
  2. Unscrew the brass pin from above the selector dial.
  3. Push the flow reducer into the bottom of the siphon tube. 
  4. Put siphon tube filter back in place and reassemble the bottle.

How it works

The selecter dial draws a measured amount of fertiliser up from the spray bottle and mixes it with water flowing through from the sprayer. Dilution rates are printed on the outside of the bottle for convenience. The benefit of this system is it allows for an even spread of fertiliser.

A note about the Fertiliser Spray Mixer

This product is suitable for use with Hoselink fertilisers and commercially available liquid fertilisers or soaps. If you are using a concentrate please follow the directions on the bottle (it may recommend diluting with water before use). 

It is not suitable for use with granulated fertilisers, compost or worm farm liquid as the sediment in these liquids will clog the spray outlet.

Clean and reuse! Fill bottle with water, set dial to 10 and spray until empty. This will prevent the contamination of multiple fertilisers/cleaning products.

Bottle holds 450ml.  Spare bottles are also available here

This product comes with a Hoselink connector included for quick connection to your Hoselink-fitted garden hose. If you are new to Hoselink then you will need to either convert your hose to Hoselink no-burst fittings (we recommend the Water Wise Starter Kit) or alternatively you can unscrew the Hoselink connector from this device and replace it with a standard click-on style male connector (please note we do not sell these).

Frequently asked questions for Fertiliser Spray Mixer

Q. How can I achieve an exact measurement?

A. In reality, you cannot achieve an exact measurement as there are many variables including your water pressure, how much concentrate you use, which brand you use, what type of product you are using.  You can vary output by increasing or decreasing the flow rate, or by increasing or decreasing the concentrate used.

Q. What Setting do I need to use?

This will depend on what type of fertiliser you are using. Recommended dilution rates will be on the back of the product. 

The dilution rates detailed on the mixer are per litre of water. Hoselink fertilisers will indicate a per litre setting on the back of the bottle
Other brands often use a dilution rate based on a 9 litre watering can. In these instances, to work out the per litre amount, divide the dilution by 9.

Use the Table Below to work out the required dilution rate:

 

Once you find your dilution rate, refer to the table on the back of the mixer to find the closet setting to achieve that dilution rate.

Q. How much fertiliser do I put in the bottle?

You can put as much fertiliser as you want in the bottle. The amount in the bottle does not determine how much fertiliser is being used. This is all based on the dilution rate setting.
It’s often easier to put in more than you need.
Any unused fertiliser can always be poured back into your fertiliser container when finished.

Q. My fertiliser bottle is filling up with water, how do I fix this?

Generally, if the bottle is filling up with water it indicates that water pressure is lacking. Try turning up the water from the tap or checking for leaks.

Q. The sprayer is not drawing up the fertiliser, only water is spraying out. How do I fix this?

Check there is enough fertiliser in the spray bottle to reach the siphon tube. Feel free to put more fertiliser in than you need as it always can be poured back into its original bottle if not needed.
If using a reducer, the dilution rate may be so great that it does not appear to be drawing up much fertiliser, and won’t be visible to the naked eye. Not sure? The best way to test this would be to fill the bottle with water, set the dilution rate to setting 10, and turn the hose on. If the liquid is sucked up, then you will know that the mixer is functional.

Q. When should I use the reducer?

Looking at the dilution rate table printed on the spray mixer;
Only use the reducer if the you cannot get the dilution rate you need without its use.
The reducer is designed for products that require a very high dilution rate. So that only a miniscule amount is used per litre of water.

Q. How do I use the reducer?

To use the reducer; remove reducer from top of selector dial. Unscrew the bottle, take the filter off the bottom of the siphon tube. Place the reducer (Thread side up) into the siphon tube and replace the filter. Screw bottle back on to spray head.

Q. Why are there 2 dilution lists on the bottle?

The two lists show the difference in dilution rate, with and without the reducer in place.
The reducer should only be used to achieve a very high dilution rate ( as per the instructions on your fertiliser)

Q. What Fertilisers / concentrate can you use in the bottle?

Most fertilisers are fine to use.
Granulated fertilisers, when used with the reducer, can cause blockages

Q. Do you have larger bottles? or spares?

We only offer the one size bottle – 450ml.

Reviews Summary
Customers say this spray mixer makes fertilizing and lawn care convenient and straightforward. Many appreciate the adjustable dilution settings, lightweight design, and easy hose attachment. Common feedback highlights its effectiveness for applying liquid products without messy mixing. However, several users report functionality issues—some units fail to draw up concentrate properly, while others experience clogging or cap attachment problems. A few mention difficulty with assembly or limited bottle capacity for larger gardens. Most who experience problems note responsive customer service and replacements, though some report persistent defects across multiple units.

    Operates perfectly.

    I was tired of buying fertiliser bottles with hose attachment that didn’t work or sprayed too fast or too slow . The Hoselink fertiliser spray mixer works exactly as advertised and I’m extremely happy.

    Fantastic and easy to use

    This sprayer makes applying liquid fertilisers so easy. It’s durable and is made of great quality components. I’ve had 2 now and they’ve outlasted the other cheaper types. Just need to make sure you have enough pressure and to rinse them out after use.

    Design flaw causes it to break if you look at it wrong

    I’ve had two of these sprayers now, both of which have broken in the exact same way - the plastic cap falls off the brass fitting when sitting it on the table, and no amount of hot water or sheer force can get it back into place. After the first issue I ordered a second one and resolved to be as careful as possible with it, yet lo and behold it happened again. I’ve just replaced mine with a $15 unit from Bunnings which is designed so that this same fault is impossible - why this one is twice the price yet has such a design flaw I’ll never know

    Thank you for taking the time to leave a review. This shouldn't be happening with your spray mixers so it's incredibly disappointing to hear. If you can please reach out to our Customer Service team on 1300 900 617 or hello@hoselink.com.au, they will be able to arrange a replacement for you under the warranty.
