Beyond NPK · understand the formulation
Declared main and trace nutrients are applied in diluted form. Refer to the full nutrient declaration for proportions.
Mix with the stated water volume and apply evenly. Never use undiluted.
The declaration lists copper, iron, manganese and zinc as EDTA chelates. Individual proportions are listed below.
Preferably use low-lime water or rainwater at 15–25 °C. Product pH describes the concentrate, not the prepared solution or compost.
Dilute according to the label and apply during growth. Check root damage and unsuitable growing conditions first.
Consider nutrients, light, water and growth stage together. Extra concentrate does not replace suitable growing conditions.
Follow this product's water quality and application directions. These do not establish a general water-treatment programme.
Suitable for compatible fertiliser dosing equipment. Set equipment to this product’s dilution and follow the device instructions.
Use complementary products according to their own directions. This profile does not approve an additional mixture.
Recommendations do not approve mixing. Combine products only when both directions allow that exact mixture. Never mix undiluted concentrates.
Declared percentages. Product pH stated on the label: 6.4.
Product pH does not specify the pH of the diluted solution or soil.
GREEN24 · Plant knowledge
Herbs are not one uniform plant group: basil grows differently from thyme, parsley from rosemary. Match position, watering and feeding frequency to the species. Harvesting does not automatically call for another feed.

Several individual pots make an inviting display while allowing different care. Basil can stay evenly moist while Mediterranean herbs dry more between waterings. The right rhythm starts with the plant.

Fine branching roots explore the growing medium. Remove only loose compost and avoid unnecessary washing or tearing.

Keep the root ball at its former level. A small gap below the rim makes watering easier; do not bury stem bases or sensitive crowns.

Leaves use light; roots take up water and mineral nutrients. The diagrams show how plant organs work together and how nutrients are absorbed.
Fine roots need contact with moist compost as well as oxygen. An open structure and drainage help provide both. Feed the pre-moistened root ball with diluted solution, never with concentrate applied directly to roots.
Green leaves use light for photosynthesis. Herbs differ in leaf structure, growth and nutrient demand; basil is an example.
Vascular tissues connect roots and above-ground parts. Xylem carries water and minerals; phloem carries substances including sugars.
A new leaf unfurls and matures. Do not force it open. Development and leaf size also depend on species, light and growing conditions.
Select a point in the picture or choose a stage.
Stage 01 / 04
The mixture reaches the compost around the fine roots. Dissolved nutrients are available at the interface between roots and growing media.
Good to knowAlways dilute the concentrate and keep to the stated dosage.
Watering carries dissolved nutrients into the growing medium around the roots. Contact with the absorbing root surfaces is the first step.
Stage 02 / 04
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.
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
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.
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
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.
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
The prepared solution wets the leaf surface. Avoid open flowers and always dilute correctly.
Good to knowThis product is labelled for foliar application. Always dilute correctly.
Foliar feeding places diluted nutrient solution on the leaf surface. Wetting depends on factors including the leaf surface and the solution.
Stage 02 / 04
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.
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
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.
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
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.
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.
Development influences requirements
For young plants, consider root establishment, light and nutrients already in compost. Unrooted cuttings are not established pot plants.
When leaves unfold and shoots develop, feeding can be part of the care routine. Keep the feeding interval separate from watering: not every necessary watering needs fertiliser.
As growth slows, check compost moisture and adjust care to demand. Do not try to force dormant plants into growth with extra fertiliser.
Actual development matters: species, location and season affect the pace. Plant size alone determines neither dose level nor watering volume.
Application & calculator →Adapt care to the growing conditions and stage of growth. If you notice changes, check light, water and roots first — then take targeted action.

Repot when needed. Allow for existing nutrients in the medium and preserve healthy roots.
Inspect leaf undersides regularly and identify the cause.
Allow air between plants; remove affected parts and avoid unnecessary overhead watering.
Check each herb’s moisture needs. Wilting can result from dryness or damaged wet roots.
These details help distinguish growing conditions, root or nutrition problems and an infestation:
Check the cause, crop and authorised growing location first. A product recommendation does not approve mixing.

Harvest leafy herbs regularly in small amounts. Some herb flowers are valuable to insects but may change leaf production or flavour. Identify edible species reliably and wash harvested herbs before use.
