Matching concentrate amount

Measure the calculated concentrate with a suitable measuring aid. Do not estimate small amounts by eye.
Enter a water amount from 0.1 to 1,000 litres.
Use the water volume actually needed. Plant height alone does not provide a reliable watering volume.
How the guide is calculated
Concentrate (ml) = water (l) × 5 ÷ 1.5.
Prepare a clean container
Use a suitable clean watering can or sprayer and follow this product's water directions.
Choose the water volume
Choose the amount actually needed. Check root-ball moisture and drainage before watering.
Add water first
Start with part of the selected water volume.
Shake and measure
Shake the bottle well. Measure the concentrate calculated for the selected water volume accurately.
Add the concentrate
Add the measured amount to the water; never apply concentrate directly to the plant.
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.

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.

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
RootsFine roots contact soil water. Their cell membranes regulate uptake of dissolved nutrients.

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

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.

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