Helpful additions to the Fertilizer Sprayer for Garden Hose
Connect the Fertilizer Sprayer for Garden Hose to your hose to quickly and conveniently dispense commercial fertilizer 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.
How to use the Fertilizer Spray Mixer
Installing the flow reduction
How it works
The selector dial draws a measured amount of fertilizer 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 Fertilizer Spray Mixer
This product is suitable for use with commercially available liquid fertilizers 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 fertilizers, 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 fertilizers/cleaning products.
Bottle holds 15oz.
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 Quick-connect Fittings (we recommend the Quick-connect Garden Hose Fitting Set) or alternatively you can unscrew the Hoselink connector from this device and screw directly onto your hose.

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.
Fertilizers 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)
(note the dilution rates are also shown in ml/L)
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 – 15oz.
