Product information
Application & dilution5 ml per 1.5 litres of water · every 4–6 weeks
Base dilution on the front label: 5 ml per 1.5 litres of water, normally May–August during active growth.
The product-specific supplement gives 5 ml per 2 litres for low-feeding planting. The front label takes precedence; consider the needs of the existing plants.
The amount of prepared solution depends on plant size and planting. Moisten before application. The supplement recommends even foliar wetting with a fine sprayer.
- 250 ml makes 75 litres at base strength or 100 litres with the weaker mixture.
- The twin pack makes twice these quantities.
- The dilution overview and six mixing steps are in Application.

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 recommendations cover products for different care tasks. Combining them in the same solution requires the instructions for both products to allow that combination. Otherwise, apply the products separately.

-
Choose dilution
Base dilution is 5 ml/1.5 L; the supplement gives 5 ml/2 L for low-feeding planting. Select the appropriate growth stage.

Nutrition & properties
Original composition
The detailed nutrient declaration and product-specific directions remain fully accessible.
Details & background
Soil and foliar feeding are possible. The supplement recommends fine, even foliar wetting. The same selected mixture is used for either route.
Plant care
First account for starter nutrients and earlier applications. Begin feeding only when new shoots appear. After new planting, wait at least 4–6 weeks, then start with one half-strength application; after about eight weeks, normal strength can be used during active growth. Pause during dormancy.
Frequently asked questions
How do I dilute the fertiliser?

What applies after new planting?
First account for starter nutrients and earlier applications. Begin feeding only when new shoots appear. After new planting, wait at least 4–6 weeks, then start with one half-strength application; after about eight weeks, normal strength can be used during active growth. Pause during dormancy.
How much prepared feed do the packs make?
At base dilution, 250 ml makes 75 litres and the twin pack 150 litres. The weaker 5-ml/2-L mixture makes 100 and 200 litres respectively.
How many square metres can I treat?
No fixed square-metre coverage is given. The appropriate volume depends on species, size and planting; follow the product-specific supplement.
How much should young plants receive?
The GREEN24 standard uses 100% for established plants, 50% for young plants and 20% for seedlings with leaves. These percentages apply to the selected base mixture; post-planting waiting periods still apply.
