Your water amount
2.5 l
Matching concentrate amount
10 ml

Measure concentrate using a suitable aid and dilute fully with water.

  1. Prepare a clean container

    Use a clean watering can or sprayer; preferably low-lime water or rainwater at 15–25 °C.

  2. Calculate the amount

    Enter the water volume and read the calculated concentrate amount.

  3. Add some water first

    Start by filling the container with part of the chosen water volume.

  4. Shake & measure

    Shake well. Measure the calculated amount using a suitable measuring aid.

  5. Add the concentrate

    Add the calculated amount of concentrate to the water.

  6. Top up & mix well

    Top up to the chosen water volume and mix well. Watering or spraying: see below.

When to feed? 10 ml per 2.5 l of water. Every 2–3 weeks according to the label. During the growing season.

Watering · through the roots

Moisten the root ball first, then distribute the mixture across the root zone. Let excess water drain through the pot; do not leave nutrient solution standing in a cachepot.

Spraying · onto the leaves

Wet the foliage lightly in the morning, evening or under overcast conditions, avoiding open inflorescences. Root and foliar feeding belong to one programme, not two parallel routines.

Fits your care routine

Culinary Herbs

For kitchen herbs; follow this concentrate's directions.

During active growth

The plant is actively growing; moisten the root ball before application.

Allow for fresh compost

Account for nutrients in fresh compost. Check the cause of care problems first.

Beyond NPK · understand the formulation

Well mixed – available to leaves and roots

Declared main and trace nutrients are applied in diluted form. Refer to the full nutrient declaration for proportions.

Water-soluble & available

Mix with the stated water volume and apply evenly. Never use undiluted.

Protected trace nutrients

The declaration lists copper, iron, manganese and zinc as EDTA chelates. Individual proportions are listed below.

Fewer hard-water effects

Preferably use low-lime water or rainwater at 15–25 °C. Product pH describes the concentrate, not the prepared solution or compost.

Target nutrition during growth

Dilute according to the label and apply during growth. Check root damage and unsuitable growing conditions first.

Understand plant development

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.

Products

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.

GREEN24 · Plant knowledge

Culinary Herbs through the year

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.

Basil, parsley, chives and thyme in separate herb pots

A herb corner for everyday life

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 basil roots with compost attached

A closer look at fine roots

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

Potted basil with watering space below the rim

Planting depth and watering space

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.

Growth & nutrient uptake

Leaves use light; roots take up water and mineral nutrients. The diagrams show how plant organs work together and how nutrients are absorbed.

What does a plant do with nutrients?

Simplified diagram · not to scale
Roots · absorb & anchorExplore the limited root space inside the pot.

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.

Leaves · capture energyGreen leaf tissue makes sugars for the whole plant.

Green leaves use light for photosynthesis. Herbs differ in leaf structure, growth and nutrient demand; basil is an example.

Shoots · support and transportCarry leaves and connect roots with growth.

Vascular tissues connect roots and above-ground parts. Xylem carries water and minerals; phloem carries substances including sugars.

New leaf · unfurl & matureInitially receives support from established leaves.

A new leaf unfurls and matures. Do not force it open. Development and leaf size also depend on species, light and growing conditions.

How nutrients enter kitchen herbs

A look inside a rootFunctional diagram of uptake routes, not species-specific microscopy.

Stage 01 / 04

Water carries nutrients to the roots

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.

A closer look

Watering carries dissolved nutrients into the growing medium around the roots. Contact with the absorbing root surfaces is the first step.

Development influences requirements

Care that follows each flush of growth

Young plant & establishment

For young plants, consider root establishment, light and nutrients already in compost. Unrooted cuttings are not established pot plants.

New leaves & shoots

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.

Lower light · slower growth

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.

Growing conditions & care problems

Adapt care to the growing conditions and stage of growth. If you notice changes, check light, water and roots first — then take targeted action.

Caring for kitchen herbs

Choose the position for the species

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.

Manage changes of position carefully

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.

Pots & repotting · consider the roots

Repot when needed. Allow for existing nutrients in the medium and preserve healthy roots.

What is changing on your herbs?

Aphids on soft shoots

Inspect leaf undersides regularly and identify the cause.

Dense, damp growth

Allow air between plants; remove affected parts and avoid unnecessary overhead watering.

One watering regime for everything

Check each herb’s moisture needs. Wilting can result from dryness or damaged wet roots.

Understand care problems before treating

These details help distinguish growing conditions, root or nutrition problems and an infestation:

  • Photos of the whole plant, both leaf surfaces, leaf stalks and affected stem nodes.
  • Species or cultivar, pot size, compost and position near a window; root photos where relevant.
  • When symptoms began and progressed, pot moisture, repotting date and previous fertiliser or plant protection applications.
Request plant advice

Check the cause, crop and authorised growing location first. A product recommendation does not approve mixing.
