- Application period
- Active growth, usually April–AugustGenerally every 1–2 weeks as needed.
Choose the right feeding approach
Standard: 1 ml per litre of water
1 ml per litre of water is the standard dilution. The reverse label gives a crop-dependent range of 1–2 ml/L. Choose the concentration for the crop and existing nutrient supply; 2 ml/L is not a universal recommendation. Feed every 1–2 weeks during active growth as needed, usually April to August for garden plants.
Check final concentration
Set the system to the intended final concentration according to its own instructions. Water flow and the amount of concentrate drawn in must be known. Example at 1 ml/L: a system delivering 100 litres of water in 10 minutes needs 100 ml of concentrate in total. This does not define a universal pump setting. If flow data are missing, measure them first in a trial run with plain water.
Feed according to the crop
Assess existing nutrients, root-zone moisture and actual growth before feeding. Soil-grown plants and closed hydroponic systems have different requirements. In hydroponics, consider water quality, crop and system management; the product label alone does not provide a complete nutrient-solution programme.
Easy application
1 ml per litre of water is the standard dilution. The reverse label gives a crop-dependent range of 1–2 ml/L. Choose the concentration for the crop and existing nutrient supply; 2 ml/L is not a universal recommendation. Feed every 1–2 weeks during active growth as needed, usually April to August for garden plants.
Enter a water quantity greater than zero.
Concentrate for this water quantity
This range follows the label dilution. It does not determine which concentration is suitable for your individual plant. Follow the application instructions.

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.

Calculate the fertiliser amount →Mixing and system application step by step
1. Choose crop and concentration
Check plant demand and existing nutrition. Standard 1 ml/L; use the label range up to 2 ml/L only according to the crop.
2. Measure the water
Measure watering volume. For automatic injection, establish flow and run time according to the equipment instructions.
3. Prepare the concentrate
Shake the bottle. At standard dilution, measure 5 ml concentrate for 5 litres of water.
4. Mix or inject
For manual mixing, start with water and stir in the concentrate. With an injection system, check dosing against the actual water throughput.
5. Apply appropriately
Apply the prepared solution to the pre-moistened root zone or wet the foliage. Avoid open flowers.
6. Account for total feeding
Include the amount applied in total nutrition. Plan another application after 1–2 weeks according to crop and growth.

Roots and foliage
Choose the appropriate application route
1 ml per litre of water is the standard dilution. The reverse label gives a crop-dependent range of 1–2 ml/L. Choose the concentration for the crop and existing nutrient supply; 2 ml/L is not a universal recommendation. Feed every 1–2 weeks during active growth as needed, usually April to August for garden plants.
Explore nutrient uptake
Understanding plant feeding
How do nutrients get into a plant?
Through the roots or through the leaves: explore four steps to discover how a plant takes up and uses nutrients.
Select a point in the picture or choose a stage.
Stage 01 / 04
Water carries nutrients to the roots
Dilute the fertiliser with water according to the label. Watering carries this nutrient solution into the soil or growing medium around the roots.
Good to knowAlways dilute the concentrate and keep to the stated dosage.
A closer look
Watering carries dissolved nutrients into the growing medium around the roots. Contact with the absorbing root surfaces is the first step.
Stage 02 / 04
Roots take up dissolved nutrients
Fine root hairs increase contact with the growing medium. Tiny transport proteins in the membranes surrounding root cells help dissolved nutrients enter the cells.
Good to knowRoots take up nutrients; they do not simply absorb all the fertiliser along with the water.
A closer look
Root hairs increase the contact area. Transport proteins in cell membranes enable mineral ions to enter; water movement and nutrient uptake are distinct processes.
Stage 03 / 04
An inner layer controls the route
On their way into the root, nutrients meet a special layer of cells. It prevents substances from simply flowing through the gaps between cells and helps the plant control uptake.
Good to knowMore fertiliser does not automatically mean better nutrition.
A closer look
Nutrients move through the root tissues. The endodermis acts as a control layer: its barrier interrupts unrestricted movement along the cell walls.
Stage 04 / 04
Transport channels carry water and nutrients
Inside the root are fine transport channels called xylem. Water and absorbed nutrients can travel through them towards shoots and leaves.
Good to knowHealthy roots and suitable growing conditions are important for nutrient supply.
A closer look
After entering the vascular tissue, nutrients can travel with the water stream in the xylem towards the shoot. Uptake and nutrient supply also depend on root health and growing conditions.

Stage 01 / 04
Diluted solution is applied to the leaf
For foliar feeding, diluted nutrient solution is sprayed onto the leaves. The product instructions tell you whether it is suitable for this use and how much to apply.
Good to knowSpray only as directed by the product instructions, never with undiluted concentrate.
A closer look
Foliar feeding places diluted nutrient solution on the leaf surface. Wetting depends on factors including the leaf surface and the solution.
Stage 02 / 04
Nutrients must cross the protective surface
The leaf surface protects the plant. Dissolved nutrients can pass through this layer; tiny openings in the leaf may also play a part. Uptake varies with the type of leaf and the conditions.
Good to knowDifferent leaves do not absorb a nutrient solution equally well.
A closer look
Dissolved nutrients can pass through the protective cuticle; pathways involving stomata may also contribute. Their relative importance varies with plant species and conditions.
Stage 03 / 04
Cells inside the leaf take up nutrients
Behind the surface lies living leaf tissue. Its cells can take up nutrients that have crossed the surface and use them for their activities.
Good to knowA droplet on a leaf does not yet mean its nutrients have been absorbed.
A closer look
After crossing the surface, nutrients can be taken up by living leaf cells. The amount depends on factors including the nutrient, formulation and environmental conditions.
Stage 04 / 04
Nutrients are used in the leaf and may move onward
The plant can use absorbed nutrients within the leaf. Some can also reach other plant parts. This depends on the nutrient and the plant's condition.
Good to knowFoliar feeding does not mean every nutrient immediately reaches the whole plant.
A closer look
Absorbed nutrients can be used within the leaf. Whether and how far they move to other plant parts depends on the nutrient and the plant's condition.

Nutrition and care
Let the crop guide feeding
Assess existing nutrients, root-zone moisture and actual growth before feeding. Soil-grown plants and closed hydroponic systems have different requirements. In hydroponics, consider water quality, crop and system management; the product label alone does not provide a complete nutrient-solution programme.

Questions about mixing and systems
How much concentrate do I need?
The standard is 1 ml per litre of water: 5 ml for 5 litres or 10 ml for 10 litres. Depending on the crop, the label range extends to 2 ml/L.
How far does each pack go?
At 1 ml/L, 250 ml treats 250 litres of water, the twin pack treats 500 litres, and 1 litre of concentrate treats 1,000 litres. At 2 ml/L, these water volumes are halved.
What setting does my fertiliser injector need?
Set the system to the intended final concentration according to its own instructions. Water flow and the amount of concentrate drawn in must be known. Example at 1 ml/L: a system delivering 100 litres of water in 10 minutes needs 100 ml of concentrate in total. This does not define a universal pump setting. If flow data are missing, measure them first in a trial run with plain water.
Is it suitable for hydroponics?
Assess existing nutrients, root-zone moisture and actual growth before feeding. Soil-grown plants and closed hydroponic systems have different requirements. In hydroponics, consider water quality, crop and system management; the product label alone does not provide a complete nutrient-solution programme.
Can I use the standard dilution for every young plant?
No. Young plants, sensitive crops and specialist systems need crop-specific nutrition. The label range does not establish a universal young-plant or seedling dilution.
When is foliar feeding useful?
The product is intended for root and foliar feeding. Even coverage and suitable conditions support foliar uptake. Do not feed in direct sun, below 5 °C or above 30 °C, and avoid open flowers.
