Measure the calculated concentrate with a suitable measuring aid. Do not estimate small amounts by eye.

  1. Prepare a clean container

    Use a suitable clean watering can or sprayer and follow this product's water directions.

  2. Choose the water volume

    Choose the amount actually needed. Check root-ball moisture and drainage before watering.

  3. Add water first

    Start with part of the selected water volume.

  4. Shake and measure

    Shake the bottle well. Measure the concentrate calculated for the selected water volume accurately.

  5. Add the concentrate

    Add the measured amount to the water; never apply concentrate directly to the plant.

  6. Top up and mix

    Top up to the chosen water volume and mix thoroughly. Water or spray according to this product's own directions.

When to feed? 5 ml per 1.5 l of water · every 6–8 weeks during active growth. Shake well before use. One capful equals 5 ml according to the label. Never apply undiluted; official advisory recommendations take precedence. Feed the pre-moistened root zone or spray foliage. Avoid open flowers. Preferably use low-lime water or rainwater at 15–25°C. Do not apply in direct sunlight, below 5°C or above 30°C.

Watering · through the roots

Moisten the root zone first. Apply the solution diluted to the label rate evenly and allow drainage. Account for the actual nutrient needs of your plants.

Spraying · onto the leaves

The label permits spraying foliage, leaving open flowers untouched. Account for species, leaf surfaces and weather. Do not apply in sun, below 5°C or above 30°C; do not double the full nutrient supply alongside root feeds.

Does it fit your care routine?

The species still matters

A rock garden groups plants by setting and design, not by botanical family. Drought-tolerant houseleeks need different conditions from moisture-loving alpine plants. First check the species, root space and nutrients already available.

Allow time between feeds

5 ml per 1.5 l of water · every 6–8 weeks during active growth. Shake well before use. One capful equals 5 ml according to the label. Never apply undiluted; official advisory recommendations take precedence. Feed the pre-moistened root zone or spray foliage. Avoid open flowers. Preferably use low-lime water or rainwater at 15–25°C. Do not apply in direct sunlight, below 5°C or above 30°C.

Check moisture before feeding

Check newly planted specimens and troughs more often. Water as needed and maintain drainage. Dry-site sun plants can dry differently from moisture-loving rock plants; do not water the whole group by one calendar.

Understand this formulation

Add nutrients at the right dilution

NPK 2.8 + 4.0 + 5.4 Product pH: 6.5. This describes the concentrate, not the resulting soil pH. 2.8% total nitrogen (N), comprising 0.65% nitrate nitrogen, 0.35% ammoniacal nitrogen and 1.80% urea nitrogen. 4.0% water-soluble phosphate (P₂O₅). 5.4% water-soluble potassium oxide (K₂O). 0.005% water-soluble boron (B). 0.002% water-soluble copper (Cu), as EDTA chelate. 0.010% water-soluble iron (Fe), as EDTA chelate. 0.006% water-soluble manganese (Mn), as EDTA chelate. 0.0005% water-soluble molybdenum (Mo). 0.002% water-soluble zinc (Zn), as EDTA chelate.

Water-soluble declaration

The composition lists nutrients declared as water-soluble on this product's own label. Mix the measured concentrate thoroughly in water.

Declared trace nutrients

See this product's declaration for amounts and any chelate bindings. This does not justify an additional unmeasured trace-nutrient feed.

Account for water and position

Follow this product's water and application directions. Concentrate pH does not establish a guaranteed pH for soil or diluted solution.

Measure accurately and store correctly

Retain the original container and labelling and follow this product's full directions.

Nutrients in context

Nutrition, light, water and root condition work together. Extra fertiliser cannot correct insufficient light or damaged roots.

Moisten the root zone first. Apply the solution diluted to the label rate evenly and allow drainage. Account for the actual nutrient needs of your plants.

Use clean suitable containers and an appropriate measuring aid.

Products

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.

Do not mix undiluted concentrates together. Follow the confirmed mixing conditions and application routes of each product.

GREEN24 · Plant knowledge

Small plants, different requirements

The drawn cushion is an example. Lime needs, moisture and heat tolerance differ among rock-garden plants.

Foliage and habit

Leaves range from water-storing to fine and thin. Evergreen species, deciduous plants and dormant bulbs occur alongside each other; foliage care depends on the species.

Flowers and development

The drawn cushion is an example. Lime needs, moisture and heat tolerance differ among rock-garden plants.

Growth and care

Check newly planted specimens and troughs more often. Water as needed and maintain drainage. Dry-site sun plants can dry differently from moisture-loving rock plants; do not water the whole group by one calendar.

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.

Roots, foliage and growth

Shoots and habitDepending on the species, ground-covering cushions, individual rosettes, small clumps or slow-growing woody plants. The group has no single growth habit.

Cushions spread flat, rosettes grow around a centre, and clumps develop from closely grouped shoots. Small shrubs have lasting woody branches. These forms need different thinning methods and should never all be clipped like a hedge.

Observe development

Distinguish growth from rest

Young plants and establishment

Spring or early autumn are suitable planting times for many species. First establish whether lime-tolerant, acidic, dry or moister conditions are needed. Keep trough drainage holes clear, retain planting depth and do not bury sensitive rosette centres.

Active growth

5 ml per 1.5 l of water · every 6–8 weeks during active growth. Shake well before use. One capful equals 5 ml according to the label. Never apply undiluted; official advisory recommendations take precedence. Feed the pre-moistened root zone or spray foliage. Avoid open flowers. Preferably use low-lime water or rainwater at 15–25°C. Do not apply in direct sunlight, below 5°C or above 30°C.

Rest period

Check drainage routes and pot feet, and remove wet fallen leaves from sensitive cushions. Hardy species do not automatically need warm quarters, while frost-sensitive members require suitable protection. Individual hardiness remains decisive.

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.

Growing conditions

In containers

Check newly planted specimens and troughs more often. Water as needed and maintain drainage. Dry-site sun plants can dry differently from moisture-loving rock plants; do not water the whole group by one calendar.

In the garden

A position between rocks can be hot and dry or cool and moist for longer. Water must drain, but free drainage does not mean letting every root dry out completely. Match sun, shade, soil reaction and moisture to the species; sensitive mountain plants may need protection from summer heat in lowland gardens.

Winter and rest

Check drainage routes and pot feet, and remove wet fallen leaves from sensitive cushions. Hardy species do not automatically need warm quarters, while frost-sensitive members require suitable protection. Individual hardiness remains decisive.

Planting and repotting

Spring or early autumn are suitable planting times for many species. First establish whether lime-tolerant, acidic, dry or moister conditions are needed. Keep trough drainage holes clear, retain planting depth and do not bury sensitive rosette centres.

Observe and identify the cause

Aphids on young shoots

Inspect tender shoot tips and leaf undersides. Identify the plant and pest before treatment; the group name does not establish a pesticide authorisation.

Slugs and vine weevils

Chewing damage and injured roots can have different causes. Inspect young plants, pot edges and root balls, and identify the cause.

Rot associated with persistent wetness

Soft plant bases and persistently wet roots call for checking drainage, compost and position. Seek advice on affected tissue; extra feeding does not remove the cause.

Discuss the care problem

These details help assess the problem:

  • Record plant species, position and recent changes.
  • Describe root-ball moisture, drainage and previous feeds.
  • Provide an overview and clear photos of affected organs.
Prepare your care enquiry

This guidance supports investigation; it does not replace a reliable diagnosis or authorised plant-protection directions.
