FlowerPower Universal Fertiliser: correct dosage
Enter your water volume or estimate the amount from the size of your plant.
Enter the water volume in litres. The calculator works out the concentrate needed. View application
Width and height give a rough guide for one root application. Choose m or cm. View application
Crown width and total tree height give a rough guide for one root application. View application
Enter the length and height of the whole hedge section. The result is for that section, not each plant. View application
Hydroponics needs product- and system-specific instructions. No permanent nutrient solution is calculated here. View application
Dosing equipment depends on flow, mixing ratio and device settings. This mode provides guidance rather than a universal dose. View application
* Severe deficiency, heavy feeders, intensified feeding. Increases the indicative application volume, not the concentration.
Please enter valid positive numbers. A comma or full stop can be used as the decimal separator.
Shake well before use. Add the concentrate and mix thoroughly.
5 ml per 2.5 litres of water
Choosing 3 or 4 litres changes the approximate amount of prepared solution to apply. The concentration is determined separately by the selected growth stage. Always mix according to the label.
A rough guide for one root application, not an exact water requirement: use your usual watering volume and the substrate’s capacity as a guide. Water the root zone first, then distribute the fertilizer solution evenly. This is not a spray volume for foliar feeding.
The calculated amount is for the entire hedge section entered, not for each individual plant.

Hydroponics
Hydroponics requires product- and crop-specific instructions. The watering dilution above is not a guide for a permanent nutrient solution. This calculator therefore does not calculate hydroponic doses, EC targets or top-up amounts for this fertiliser concentrate. Please discuss the product and your hydroponic system with our advisers.
Contact our advisers →Irrigation system / fertilizer injector
Dosing units, irrigation systems and fertilizer injectors need settings suitable for the product and equipment. Plant size alone cannot determine pump settings, running time or a stock solution.
- Establish the actual water flow and intended running time.
- Check injection ratio, suction and product suitability against the equipment and product instructions.
- Prepare a flow test with clean water according to the equipment instructions. Do not use the normal watering dilution as continuous injection without checking its suitability.
