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.

The set instructions describe diluting the supplied NPK and iron components together. Measure each component separately.

The manufacturer confirmation for plant-specific GREEN24 liquid fertilisers names Kiron® Milben-Ex, Schädlings-Frei-Organic and Trauermückenfrei Organic as individual mixing partners. This does not additionally confirm mixing the NPK component, iron component and a plant protection product together.

The selected plant protection product’s current instructions must cover the crop, pest, application site and method. Mixing the three plant protection products with one another is not confirmed either.

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.

Schädlings-Frei-Organic
Schädlings-Frei-Organic

Combine fertilising and plant protection

For an explicitly confirmed mixing partner. Confirmation applies to each product individually.

  1. Prepare the fertiliser solution using the appropriate water volume and dosage.
  2. Use the selected plant protection product’s instructions to determine its dosage and application rate, then add it to the prepared fertiliser solution.
  3. 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.

Details & background

A dense lawn grows from several care decisions working together: light, mowing, soil and water matter alongside nutrients. This two-component liquid set supplies NPK and iron to established turf when needed.

The set contains two bottles of NPK concentrate and one bottle of iron concentrate, each holding 250 ml. The components have different declarations and must be measured separately. Dosage refers to the lawn area treated.

30 ml NPK component + 15 ml iron component in 5 litres of water for 100 m².

  1. Check need and area

    Check need and area

    Measure the area, account for previous feeding and protect sensitive surrounding surfaces. Soil should be moist and foliage dry before application. Wear protective clothing and eye protection as directed.

  2. Prepare the water

    Prepare the water

    For 100 m² prepare five litres of preferably low-lime water in a suitable clean watering or spraying device. This is the carrier volume for even application, not a substitute for necessary soil irrigation.

  3. Measure the NPK component

    Measure the NPK component

    Shake the NPK bottle and accurately measure 30 ml for 100 m². This is the component labelled NPK 12 + 4 + 6. Add it to the prepared water.

  4. Add the iron component

    Add the iron component

    Measure 15 ml iron concentrate separately for 100 m² and add it to the diluted mixture. The iron bottle carries WARNING and the exclamation-mark pictogram. Avoid skin and eye contact.

  5. Apply evenly

    Apply evenly

    Mix and distribute the solution evenly across the measured 100 m². Do not apply in direct sunlight, below 5 °C or above 30 °C. Avoid spray drift and inhalation. Do not add other products.

  6. Follow with appropriate irrigation

    Follow with appropriate irrigation

    According to the leaflet, once the spray has dried, water the soil well within 1–3 days. Clean equipment and do not dispose of leftovers into waterways. Observe the turf; do not automatically repeat on a weekly schedule.

Watering a lawn

Coordinate water and nutrients

April to the end of August. According to the leaflet, applications of other lawn fertilisers must be at least 2–3 months earlier; account for existing nutrients and actual need.

Frequently asked questions

Can I use only the iron component?

The area dose shown here applies to the complete set. Using one component alone requires its own suitable instructions; do not treat the iron amount as ordinary NPK feed.

Is the set intended for new grass seedlings?

The instructions describe feeding an existing lawn. For overseeding, focus on the seedbed, moisture and initial nutrients; do not automatically add concentrated iron feed.

How often should I treat?

April to the end of August. According to the leaflet, applications of other lawn fertilisers must be at least 2–3 months earlier; account for existing nutrients and actual need. The leaflet does not prescribe a universal weekly schedule.

Does fertiliser replace investigating moss?

No. Assess shade, waterlogging, soil compaction, mowing and nutrient needs separately. The set is described here as fertiliser, not as an authorised moss-control product.

Can I mix in other products?

The set instructions describe diluting the two supplied components together. This is not permission to add other fertilisers or plant protection products.

Super Produkt. Einfach und ergiebig in der Anwendung.
Habe ca. 800qm Rasen, die ich damit ganz leicht - mit Sofortwirkung - stärken wollte.
Hat super funktioniert.
gerne wieder.

Wir hatten diesen Dünger vor ein paar Jahren bereits benutzt und waren schon damals sehr zufrieden. Die Anwendung ist recht simple, einfach gemäß Anleitung anmischen und mit einem Sprühgerät oder einer Gießkanne auf den Rasen verteilen. Sieben bis zehn Tage später ist die volle Wirkung eingetreten. Man sieht es an der schönen dunkelgrünen Farbe des Rasens und natürlich wächst er auch wieder viel schneller. Eine tolle Sache zum Düngen und wegen des Eisens auch zum Moos vertreiben.

Danke für die schnelle Lieferung. Meine Erfahrung: Der Dünger wirkt sehr schnell, die Wiese bekam eine schöne dunkelgrüne Farbe. Hätte nicht gedacht, dass es so schnell geht. Ich habe den Dünger mit einer kleinen Gartenspritze ausgebracht. Schön wären noch größere Flaschen. An sonsten bin ich sehr zufrieden.
