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.
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 litre of water Every 2–3 weeks during active growth. During active growth Shake before use, measure and mix into the water. Account for existing nutrients and plant needs.
Watering · through the roots
For rooted plants, moisten the root ball, apply diluted feed and allow surplus water to drain.
Spraying · onto the leaves
Distribute diluted solution evenly over upper and lower leaf surfaces. Avoid open flowers.

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.
For rooted plants, moisten the root ball, apply diluted feed and allow surplus water to drain.
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.

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 regularly during growth; water less in cool winter quarters. Empty the saucer.
In the garden
Sun to partial shade, sheltered from wind and with good drainage. A container and bright, cool winter quarters suit central European cultivation.
Winter and rest
Move containers to a bright, cool position in good time; protect the root ball from freezing.
Planting and repotting
Repot in spring when roots need more room and retain the previous planting level.
Observe and identify the cause
Check for scale
Inspect leaf undersides and shoots for attached scales and sticky deposits.
Rolled leaf margins
Inspect distorted young leaves for bay suckers.
Roots and drainage
When leaves yellow, first compare moisture, drainage and location.
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.
