Product Info

Connect the Fertiliser Spray Mixer to your hose and quickly and conveniently dispense commercial fertiliser or weed spray on to 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.

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 siphon tube.
  2. Unscrew the brass pin from above the selector dial.
  3. Push the flow reducer into the top of the siphon tube. Top tip: place brass pin on a hard surface and push siphon tube down until flush.
  4. Put siphon tube back in place firmly 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 our car cleaning range as well as commercially available fertilisers or weed sprays. If you are using a product from a pre-mixed spray bottle, simply tip it straight in. If you are using a concentrate please follow the directions on the bottle (it may recommend diluting with water before use).

Not suitable for low water pressure or use with water tanks.

It is not suitable for use with 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.

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, reduce 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.
Spare bottles will be available late 2020

Fertiliser Spray Mixer

Great, but a bigger bottle would be even better, maybe 1 litre or even more.

Very good thing

This is my first hoselink purchase, didn't realise it had a non-standard fitting. It prompted me to go to the website where I discovered the hoselink world. I got the fitting and the spray mixer is awesome. I have since gone back and refitted all my hoses with hoselink fittings and am very happy. No more constantly leaking fittings.

Didn’t know it wouldn’t fit on a normal hose

Once I found out about the fitting, the Hoselink Customer Service person was very helpful in recommending a solution and discounting my adapter

Great Product

This product works exactly as you expect and want it to. The adjustable dial on top works great and allows you to dial in exactly the right amount of mixture. It is brass material, not cheap plastic, so should last a decent amount of time and uses. Whilst this mixture nozzle is available elsewhere, I wanted to buy from an Australian to support our economy.

First try a failure

I used the product first on seaweed solution, but it got clogged in the restricter. I couldn't get it to work at all. After contacting hoselink, they sent me a new one. I have used this on lawn fertiliser, without the restricter and it works fine. A bit nervous about using the seaweed again. Can only partially recommend this product.

Great for home use

Quite good overall however there were a few issues. - mixer ratios were not as precise as they could be, after calibration I found they were a little bit out. - the top of the mixer bottle could do with a wider opening - better filtration on the intake hose, I want to be guaranteed that the mixer will not clog no matter what I’m spraying out - the hose intake hose did not reach the bottom of the bottle. I would have liked a longer hose and the bottle having a rounded bottom. Buttress like supports on the outside of the bottle would keep it upright when filling even with the rounded bottom. Was planning to use this product in a professional setting however these issues keep me from doing that, love using mine at home for my little veggie patch and gardens though.
