Use the label dilution
5 ml per 2 litres of water. Every one to two weeks during active growth, for roots and foliage. No additional fixed autumn or winter programme.
Check growth and water needs
Keep Maranta in bright light away from intense direct midday sun. Combine even moisture, adjusted to need, with good drainage; do not treat Maranta and Calathea as the same plant. Do not impose a fixed winter feeding programme.
Apply safely
Apply only after dilution. Root and foliar feeding are alternative application routes. Follow the full safety and storage instructions below.
Application in one place
Measure. Mix. Apply.
Maranta Fertiliser calculator
Enter the water volume you actually need. The calculator works out the matching concentrate amount from the label; it does not determine your plant’s water needs.
Your water amountRough watering-volume guide
2 l
Matching concentrate amount
5 ml
Measure the concentrate accurately. Use a suitable measuring aid for small quantities; never apply undiluted.
Enter a water amount from 0.1 to 1,000 litres.
Prepare a clean container
Prepare a clean, suitable watering can or sprayer. Prefer low-lime water or rainwater at 15–25 °C.
Calculate water and concentrate
Choose the required water volume and development stage: established plants 100%, young plants 50%, seedlings with leaves 20% of the product-specific base dose.
Add some water first
Start by adding part of the chosen water volume to the container.
Shake and measure
Shake the bottle well and measure the calculated concentrate quantity accurately. Wear gloves and safety goggles when mixing.
Add concentrate to the water
Add the measured concentrate to the water already in the container. Do not mix undiluted concentrates together.
Top up and mix
Top up to the chosen water volume and mix thoroughly. Use the diluted solution promptly for watering or spraying.
When to feed? Every one to two weeks during active growth, for roots and foliage. No additional fixed autumn or winter programme. Feed only during active growth and respect any species-specific rest period.
Watering · through the roots
When watering is needed, moisten the root zone before feeding. Distribute the diluted solution evenly and let excess water drain away. Do not feed dry or waterlogged root balls.
Spraying · onto the leaves
Spray leaf surfaces with the label dilution, avoiding open flowers. Do not apply in direct sunlight, below 5 °C or above 30 °C. Do not inhale spray mist; wear gloves and safety goggles. Foliar feeding replaces a corresponding root feed rather than adding a second feeding programme.

Major and trace nutrients in the concentrate
NPK 5 + 6 + 5.2. The following facts come from the original declaration, without an additional performance claim.
Declared EDTA chelates
Copper, iron, manganese and zinc are declared as EDTA chelates. Full contents are listed under nutrient composition and on the original reverse label.
Consider the source water
The general instructions recommend low-lime water or rainwater. Product pH refers to the concentrate, not a guaranteed pH of the diluted solution or growing medium.
Understand formulation and application
Nutrient figures describe composition. They do not replace the label dilution or checking light, drainage and actual growth.
Starting materials: NPK fertiliser. Product pH: 6.6. The pH of the prepared mixture also depends on the source water; no fixed target is promised.
Use clean, chemically suitable equipment. Keep to the measured water volume and calculated concentrate amount, and follow the full safety instructions.
Plant form and nutrient uptake

What the drawing shows
- Maranta leuconeura illustrates the low-growing habit with oval, contrastingly veined leaves.
- Other Maranta species and forms may look different; Calathea is not treated as the same plant.
Roots and internal tissues are functional schematics, not anatomical sections drawn to scale.
Roots and leaves in a functional schematic
Four stations put possible nutrient pathways in context. The drawings explain principles, not the uptake performance of this fertiliser.
Select a number to explore the station.
Station 01 / 04
Diluted solution in the root zone
The solution, diluted according to the label, reaches the previously moistened root zone.
Important: Do not fertilise dry growing medium.
A closer look
The drawing shows solution in the medium, not a prescribed watering volume.
Station 02 / 04
Contact with the root
Roots take up water and dissolved mineral nutrients.
Important: Healthy roots and suitable growing conditions remain essential.
A closer look
The root symbol is functional. It specifies neither actual root depth nor a particular root architecture.
Station 03 / 04
Entry into plant tissue
The simplified cells represent the route from the root zone into the plant.
Important: This is not a microscopic section.
A closer look
Cell numbers, shapes and spacing are teaching aids, not evidence of species-specific anatomy.
Station 04 / 04
The whole-plant context
The plant sketch places root uptake in the context of the whole plant.
Important: Feed only during active growth, following the label.
A closer look
Arrows or plant size imply neither a performance claim nor an additional fertiliser requirement.
Station 01 / 04
Diluted solution on a leaf
The leaf drawing shows contact between diluted solution and a leaf surface.
Important: Follow the label; do not spray open flowers.
A closer look
The drops are symbols, not instructions for droplet size, spray volume or application technique.

The surface as a boundary
Wetting does not mean that all applied nutrients are absorbed.
Important: Contact and uptake are not the same.
A closer look
The layers represent a generic leaf surface. They show neither species-specific pores nor a single exclusive entry route.
Station 03 / 04
Possible uptake into tissue
Entry into tissue depends on the nutrient, leaf surface and environmental conditions, among other factors.
Important: No species-specific uptake rate is claimed.
A closer look
The drawing explains a general principle, not a particular uptake speed or rate for this plant species.
Station 04 / 04
Redistribution varies
Absorbed nutrients do not all move equally far from the treated leaf.
Important: Do not infer a general systemic effect.

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.
Through the roots
A look inside a root Enlarged, simplified illustration
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 know Always 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.
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 know Roots 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.
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 know More 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.
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 know Healthy 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.

Through the leaves
A look inside a leaf Enlarged, simplified illustration
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 know Spray 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.
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 know Different 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.
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 know A 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.
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 know Foliar 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.
