Agapanthus Fertiliser: correct application

Dilution, application interval and declared composition for Agapanthus.

Declared NPK
2.8 + 3.8 + 5.7With declared trace nutrients.
Dilution
10 ml per 2.5 litres of waterEvery 1–2 weeks during active growth.
Application
Roots & foliageDilute with water before use.
Regular application period
April–SeptemberApply only during active growth.

Match application to the plant

Use the label dilution

10 ml per 2.5 litres of water, every 1–2 weeks during the growing period, for watering or spraying. Regular application period on the label: April to September.

Check growth and water needs

Account for growth and actual water needs.

Apply safely

Apply only after dilution. Root and foliar feeding are alternative application routes. Follow the full safety and storage instructions below.

Application in one place

Measure. Mix. Apply.

Dose calculator: Agapanthus Fertiliser

Enter the water volume you actually need. The calculator works out the matching concentrate amount from the label; it does not determine your plant’s water needs.

Your water amount
2.5 l
Matching concentrate amount
10 ml

Measure the concentrate accurately. Use a suitable measuring aid for small quantities; never apply undiluted.

  1. Prepare a clean container

    Prepare a clean, suitable watering can or sprayer. Prefer low-lime water or rainwater at 15–25 °C.

  2. Calculate water and concentrate

    Choose the required water volume and development stage: established plants 100%, young plants 50%, seedlings with leaves 20% of the product-specific base dose.

  3. Add some water first

    Start by adding part of the chosen water volume to the container.

  4. Shake and measure

    Shake the bottle well and measure the calculated concentrate quantity accurately. Wear gloves and safety goggles when mixing.

  5. Add concentrate to the water

    Add the measured concentrate to the water already in the container. Do not mix undiluted concentrates together.

  6. Top up and mix

    Top up to the chosen water volume and mix thoroughly. Use the diluted solution promptly for watering or spraying.

When to feed? 10 ml per 2.5 litres of water, every 1–2 weeks during the growing period, for watering or spraying. Regular application period on the label: April to September.

Watering · through the roots

When watering is needed, moisten the root zone before feeding. Distribute the diluted solution evenly and let excess water drain away. Do not feed dry or waterlogged root balls.

Spraying · onto the leaves

Spray leaf surfaces with the label dilution, avoiding open flowers. Do not apply in direct sunlight, below 5 °C or above 30 °C. Do not inhale spray mist; wear gloves and safety goggles. Foliar feeding replaces a corresponding root feed rather than adding a second feeding programme.

Product properties 250 ml or 2 × 250 ml

Compost and other care products

Nutrients already in pre-fertilised compost and previous feeds contribute to the overall supply. Do not increase the dose to compensate for inadequate light or unsuitable watering.

No product-specific approval for mixing with other care or plant-protection products is provided here. Without explicit confirmation, apply separately and follow both products’ instructions.

Declared EDTA chelates

Copper, iron, manganese and zinc are declared as EDTA chelates. Full contents are listed under nutrient composition and on the original reverse label.

Consider the source water

The general instructions recommend low-lime water or rainwater. Product pH refers to the concentrate, not a guaranteed pH of the diluted solution or growing medium.

Understand formulation and application

Nutrient figures describe composition. They do not replace the label dilution or checking light, drainage and actual growth.

Use clean, chemically suitable equipment. Keep to the measured water volume and calculated concentrate amount, and follow the full safety instructions.

Agapanthus forms clumps of strap-shaped leaves and fleshy roots. The photographic scene shows a garden hybrid in a pot. Sunlight and appropriate winter care matter alongside nutrition.

The correct mixture

10 ml per 2.5 litres of water.

Two capfuls equal 10 ml. Use 12 ml concentrate for 3 litres of water. Match the amount of prepared solution to root space or leaf area and account for existing fertiliser.

Mix, water or spray

Mix your fertiliser – step by step

Prepare the amount of nutrient solution you need. The dilution depends on this product and the required amount of water.

  1. Clean the container

    Clean the watering can, sprayer or bucket and rinse it with clean water.

  2. Calculate the dose

    Choose the amount of water you need and calculate the matching concentrate dose. The dosage calculator helps you do this.

    Dilution: 10 ml per 2.5 litres of water

    Calculate the right amount →
  3. Add some water

    Pour part of the calculated amount of water into the container first.

  4. Shake, open & measure

    Shake the closed bottle well. Then open it and measure the calculated concentrate dose with the dosing cap. Measure more than once if needed.

    A full dosing cap holds 5 ml. Use suitable millilitre graduations for smaller amounts.

  5. Add the concentrate

    Pour the measured concentrate into the water already in the container.

  6. Add the remaining water & mix

    Add the rest of the calculated water and mix thoroughly. Your diluted nutrient solution is ready.

Dosage and water choice

Shake well before use. Choose the volume of water and measure the calculated concentrate dose. Pack size does not change the dilution.

Preferably use low-lime water or rainwater at 15–25 °C. Add the measured concentrate to the water and mix thoroughly. Never apply undiluted; prepare only what you need.

When applying the solution

Check growth, growing-medium moisture and previous feeding. Feed only during active growth.

Regular application period: April–September

For root feeding, moisten dry growing medium with water first. Check drainage; the pot should not remain standing in water.

Distribute the diluted solution over the pre-moistened root zone or spray the foliage. Do not spray open flowers. Do not apply in direct sunlight, below 5 °C or above 30 °C. Do not inhale spray mist.

Follow the safety instructions →

Through the root zone

Apply the diluted solution to the pre-moistened root ball. Allow excess water to drain from containers; account for initial and additional feeds.

Through the foliage

Wet foliage according to the label and avoid open flowers. A foliar feed counts towards total nutrition and is not automatically added to root feeding.

Feed roots and foliage

Choose the appropriate application method.

The label permits watering and spraying at the same dilution. Both routes count towards total nutrient supply. Avoid open flowers; a foliar feed is not an automatic extra portion.

Understanding plant feeding

How do nutrients get into a plant?

Through the roots or through the leaves: explore four steps to discover how a plant takes up and uses nutrients.

Stage 01 / 04

Water carries nutrients to the roots

Dilute the fertiliser with water according to the label. Watering carries this nutrient solution into the soil or growing medium around the roots.

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.

Frequently asked questions

Questions before the next feed

How far do the packs go?

At the stated dilution, 250 ml makes 62.5 litres and the twin pack 125 litres of feed solution.

Why is my agapanthus not flowering?

Check light, winter conditions, dry spells and the roots. An oversized or excessively root-bound pot and heavy division can delay flowering.

Should all leaves be removed in autumn?

Only deciduous types lose their foliage. Keep healthy leaves on evergreen plants and gently remove yellow or dead ones.

When should I feed after repotting?

Account for fertiliser already present in the compost. Follow its advice on when to resume feeding and observe actual growth.

Should I spray the flowers?

No. The label excludes spraying open flowerheads. For foliar application, wet suitable leaf surfaces evenly.

Understand care problems
