Frequently asked questions for Spare Bottle 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, 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

Spray mIxer

This is an excellent product and is well made. It ideally suits those of us getting older who cannot lug around large bottles with plastic spray attachment where you end up wetter than the plants. The Hoselink system of fertilizer spray mixer along with the tap and hose connectors a great choice.



Thank you for taking the time to leave a review Kevin! Pleased to hear it is making your Fertilising easier! Happy Gardening

Works great

Fertiliser spray mixer and spare bottle. I’m using them to bath my two large breed dogs, (maremmas).as a suds and soap diffuser. One bottle for shampoo. One for conditioner. I know it’s not your traditional use, but it may give other customers the idea. They work great. It really helps get the shampoo right to the skin. We use way less shampoo too.

Needs a Revision!

After ordering a spare bottle and finding it is bowed out at the bottom and doesn’t sit flat as a result. I requested a replacement, only to find it has the same fault. So I assume this is not something that Hoselink intend to fix? Or perhaps even see is an issue? Guess I have to live with it! Perhaps someone can make a decision and let me know?



Hi Chris, thank you for your review and feedback. Surprisingly, not something that has been brought to our attention until now but can definitely understand why this would be problematic, especially when filled with fertiliser! This has been passed over to our product team who will be able to follow up with our manufacturers and get this all figured out. Sorry again for your experience. Leave it with us! Kind regards, The Hoselink Team

The product works exactly as it should, however could you please make a 2 litre bottle, it's just way to small.

Fertiliser spray

I actually purchased the spray gun with bottle and a spare bottle. I thin they are very good, useful for spraying anything you need to in the garden. I particularly bought an extra spray bottle to spray disinfectant after picking up my pet dogs droppings. This has proved very useful, and gets rid of the flys etc. It is very efficient, and saves my using excessive disinfectant, or not enough. I am particularly impressed with the varied ratio you can use for any spraying.
