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.

Application & dosageMandatory instructions and the product leaflet.
Mandatory application instructions

Suitable for soil and foliar feeding.
Please follow the product-specific information on the label and in the full description.
Mixing with other productsMixing, combining or applying separately
Using products as part of the same care routine is different from mixing them in one container. Follow the labels and application instructions of all products involved.
- Tank mixing: Combine products in a watering can or spray tank only when the manufacturer instructions confirm the specific combination and use. Do not mix undiluted concentrates together.
- Separate application: Applying products separately or at different times does not automatically establish compatibility. Check the species, location, plant condition and instructions for both products. No universal waiting period follows from this.
- Complementary products: A recommendation for suitable growing media, accessories or another care product does not mean that it may be mixed with the fertiliser.
- Plant protection products: The crop, target organism, application method and pack instructions must also be suitable. The fertiliser calculator does not calculate plant protection product quantities or confirm compatibility.
Plant protection products and application
Check the plant species, pest and location for each product. Use the current instructions for dosage, application rates and water volumes.
Combine fertilising and plant protection
For an explicitly confirmed mixing partner. Confirmation applies to each product individually.
- Prepare the fertiliser solution using the appropriate water volume and dosage.
- Use the selected plant protection product’s instructions to determine its dosage and application rate, then add it to the prepared fertiliser solution.
- Mix thoroughly and use for the specified watering or spray application.
The fertiliser calculator calculates fertiliser only. Its watering volumes and young plant or seedling adjustments do not apply to plant protection products.
Use plant protection products safely. Always read the label and product information before use.
