Only a rough guide to root watering one rose bush. Measure height from the soil and full leafy width. For climbing roses and continuous beds, use the water volume actually needed. Check moisture, roots, substrate and weather.
How the guide is calculated
General GREEN24 guide: height (m) × width (m) × 3–4 litres. Centimetres are converted to metres. The concentrate amount follows this fertiliser’s dilution. The guide does not measure individual water requirements.
Prepare a clean container
Use a clean watering can or sprayer; preferably low-lime water or rainwater at 15–25 °C.
Calculate the amount
Enter the water volume or use the size guide for one shrub. Check root-ball moisture and drainage before watering.
Add some water first
Start by filling the container with part of the chosen water volume.
Shake & measure
Shake the bottle. 1 capful = 5 ml; use a measuring aid for smaller partial amounts.
Add the concentrate
Add the calculated amount of concentrate to the water.
Top up & mix well
Top up to the chosen water volume and mix well. Watering or spraying: see below.
When to feed? Feed every 1–2 weeks from April to September during active growth when extra nutrients are needed. Account for fresh compost and earlier feeds; pause during dormancy.
Watering · through the roots
Moisten the root ball first, then distribute the mixture evenly through the root zone. Ensure free drainage in pots and check soil moisture in borders. Do not feed dry or waterlogged roots.
Spraying · onto the leaves
Mist rose leaves finely in the morning, evening or under cloud cover; avoid open flowers. Foliar feeding belongs in the same plan as root feeding.

Request the compatibility table →Beyond NPK · understand the formulation
Well mixed – available to leaves and roots
Water-soluble nutrients and coordinated formulation properties make feeding your rose straightforward. Explore what the diluted mixture provides for leaves and roots.
Protected trace nutrients
Copper, iron, manganese and zinc are declared as EDTA chelates. This binding helps keep these trace nutrients available in solution.
pH buffering for the mixture
The buffer system helps regulate the pH of the finished watering or spraying solution. The source water also influences the resulting value.
Even coverage on the leaf
Good wetting and adherence help distribute the spray solution across the leaves. Dissolved nutrients are then available at the leaf surface for uptake.
Reduce hard-water effects
Prefer low-lime water or rainwater at 15–25°C for mixing. The formulation can reduce hardness effects; no particular soil pH is promised.
Feed with plant tolerance in mind
High plant compatibility when used correctly supports the development of leaves and flowering shoots. Balanced nutrition supports your rose’s natural foliage quality.
Understand foliage quality and flower development
Nitrogen contributes to chlorophyll and protein formation, phosphorus to energy transfer and potassium to water regulation. Flowering also depends on cultivar, light, water and pruning.
Chelation can reduce interfering effects of water hardness; it does not remove calcium and magnesium. The concentrate pH of 6.2 does not specify garden soil pH.
Use clean, suitable watering or spraying equipment. Measure the water and calculated concentrate quantity carefully.
Create a flowering space
Compound leaves. Varied blooms. A living garden.
Roses produce new shoots, compound leaves, buds and blooms. The garden scene is an AI-generated example; growth and flowering vary by cultivar and site.
Support your rose through its growing season.
The concentrate supplements nutrient supply. Sunlight, root space, water and suitable pruning remain important for roses. More fertiliser does not guarantee more flowers.
Compound leaves on a rose shoot
Compound rose leaves with serrated leaflets use light to form sugars. Leaf colour and health also depend on water, position and pests or diseases.
Blooms with different forms
Buds and blooms develop differently with cultivar and weather. Nutrients support growth but cannot replace light, water or suitable pruning.
New shoots, new possibilities
New shoots extend the bush and carry leaves and flowers. Remove dead or diseased wood selectively; pruning depends on rose group and flowering habit.
A flowering place in the garden
The scene shows compact roses as one example. Other rose forms also need a suitable position, sufficient root space and regular observation.
From root zone to buds and blooms
How does a rose use nutrients?
Fine rose roots take up water and mineral nutrients. Compound leaves use light to form sugars for growth. Woody shoots connect the plant and carry leaves and blooms. Flower development also depends on cultivar, light, pruning and position.
Roots · absorb and anchorFine roots explore evenly moist, aerated soil.
Active roots need water and oxygen. Humus-rich, free-draining compost and open drainage holes support the root zone in pots. More fertiliser cannot compensate for waterlogging or a dried-out root ball.
Shoots · support & connectWoody shoots carry foliage, buds and flowers.
Conducting tissue connects roots and above-ground parts. Potassium contributes to water regulation and transport. Plan pruning for the rose group and flowering habit rather than cutting every shoot alike.
Leaves · capture energyCompound leaves use light to form sugars.
Nitrogen contributes to chlorophyll and proteins; iron and manganese have roles in metabolism. Yellow leaves can still have several causes. Assess leaf age, moisture, soil reaction and roots together.
Flowers · development & diversityRose blooms develop from buds; size and form vary by cultivar.
Phosphorus is involved in energy transfer, but it alone cannot guarantee a flower count. Bud development also depends on cultivar, light, water and pruning.
Understanding plant feeding
How nutrients enter your rose
Roses form compound leaves, woody shoots and blooms that differ by cultivar. Roots need moisture without waterlogging. Root and foliar feeding are two permitted routes for this fertiliser within one feeding plan. Do not spray open flowers.
Select a point in the picture or choose a stage.
Stage 01 / 04
The solution reaches the rose root ball
Apply the diluted mixture to the previously moistened root zone. Wet the root ball evenly without leaving water standing in an outer pot.
Good to knowAssess wilting through root-ball moisture and root health before increasing fertiliser.
A closer look
The first step is contact between dissolved nutrients and root regions capable of uptake. The diagram shows this function, not a species-specific tissue section. Assess wilting through root-ball moisture and root health before increasing fertiliser.
Stage 02 / 04
Uptake at the fine roots
Fine roots and root hairs contact the soil or growing medium. Dissolved nutrients enter root cells through regulated processes.
Good to knowFresh compost and existing soil reserves already contribute to your rose's nutrition.
A closer look
Root hairs increase the contact area. Transport across cell membranes is distinct from water movement alone. Fresh compost and existing soil reserves already contribute to your rose's nutrition.
Stage 03 / 04
Root cells regulate uptake
Cell membranes and transport proteins regulate the entry of dissolved nutrients. These processes are distinct from water moving through the plant.
Good to knowA stronger concentration cannot replace healthy roots or adequate rooting space.
A closer look
Controlled processes within living root cells lie between the surface and the conducting tissue. Functional blocks do not depict the entire root anatomy. A stronger concentration cannot replace healthy roots or adequate rooting space.
Stage 04 / 04
Onwards to shoots and rose leaves
After uptake, water and nutrients can travel through the xylem into shoots and leaves. Growth and flower development still depend on species, cultivar and growing conditions.
Good to knowWater and nutrient transport support new rose shoots; pruning and flowering habit depend on the rose group.
A closer look
Xylem transports water and dissolved substances. Root health and growing conditions affect uptake and movement. How new shoots flower differs among rose groups.
Stage 01 / 04
The solution wets the rose leaves
Apply the diluted mixture finely to the leaves. Avoid open flowers; they are not the target of foliar feeding.
Good to knowCount foliar applications within the shared feeding plan, not automatically on top of a full root application.
A closer look
The leaf surface must contact the diluted solution. Wetting is the first step, not evidence that nutrients have already been absorbed. Count foliar applications within the shared feeding plan, not automatically on top of a full root application.
Stage 02 / 04
Across the rose leaf surface
The leaf blade has a protective surface. Dissolved nutrients can cross it; leaf age and application conditions affect uptake.
Good to knowA larger bloom is no reason to increase spray strength.
A closer look
Nutrients can cross the protective cuticle, and stomatal routes may contribute. Their role depends on conditions. A larger bloom is no reason to increase concentration.
Stage 03 / 04
Use by living leaf cells
Nutrients that have entered the leaf can be absorbed by its cells and used in metabolism. A visible droplet alone is not evidence of uptake.
Good to knowYellowing leaves have several possible causes. Also check soil reaction, watering and roots.
A closer look
After crossing the surface, nutrients can be taken up by living leaf cells. Quantity also depends on the nutrient and surrounding conditions. Yellowing leaves have several possible causes. Also check soil reaction, watering and roots.
Stage 04 / 04
Use and possible redistribution
Movement from the leaf depends on nutrient and plant condition. Foliar feeding alone cannot guarantee a flower count.
Good to knowFoliar feeding does not replace healthy roots or checks of light and water.
A closer look
Whether and how far nutrients move from a leaf to other parts varies among nutrients. Immediate supply to the whole plant cannot be inferred. A foliar feed alone cannot promise more blooms.
Development influences requirements
Distinguish establishment, growth and dormancy
Establishment & young roses
After planting, first ensure even root-ball moisture and free drainage. Fresh compost may already contain fertiliser. Base the start of feeding on root condition and existing nutrition, not plant height alone.
Leaf, shoot and flower development
Feed at the labelled interval during active growth when extra nutrients are needed. Do not try to correct poor flowering with stronger dilution: light, pruning, frost or drought may be involved.
Dormancy & bud protection
Pause feeding during dormancy. Many garden roses drop their leaves in autumn; new growth can be damaged by late frost.
Consider species, growth stage, root condition and existing nutrients together. Height or flower count alone does not justify changing the dilution.
Application & calculator →Your growing conditions matter
How does your rose grow at its site?
Sun, airflow, free-draining soil and sufficient root space help roses. Pots dry out faster; pruning and winter care depend on rose group and location.
Pots · moisture and rooting space
Use a sufficiently large pot with free drainage. Check root-ball moisture regularly during warm weather and flowering. Keep compost evenly moist without waterlogging; do not leave water standing in an outer pot.
Borders · account for soil reserves
Free-draining garden soil and consistent, appropriate watering form the basis. Established roses do not automatically need extra fertiliser. A soil test can help when supply is unclear.
Winter · roots and flower buds
Assess hardiness by cultivar and location. Protect pot roots from severe freezing while retaining drainage. Do not feed in dormancy.
Repotting & pruning · match the species
When repotting, inspect the root ball and choose a suitable container with drainage. Account for nutrients in fresh compost. Choose pruning time and severity for the rose group and flowering habit.
For your rose’s root zone
Rosa compost is available for the next repotting. Its existing fertiliser forms part of the total nutrient supply and affects when liquid feeding begins.

Rose Compost
€8,90 View product10 litres of rose compost for repotting. Account for starter nutrients when planning further feeding.
Understand plant care problems
What is changing on your rose?
Wilting, yellow leaves or missing flowers do not always mean a nutrient shortage. Check root-ball moisture, drainage, hot sun, frost and the last pruning. Inspect new shoots and leaf undersides too.
Aphids and feeding damage
Inspect young shoots, observe natural predators and identify the cause.
Black spot, rust and mildew
Inspect foliage regularly; distinguish symptoms and consider position, cultivar and air movement.
Dry wall positions
Rain often fails to reach roots beside walls. Check soil moisture before interpreting leaf loss only as nutrient deficiency.
Advice for your rose
These details help assess growing conditions, root problems or a possible infestation:
- Photos of the whole shrub, both sides of affected leaves, stems and any flower buds.
- Species or cultivar, garden or container, light conditions, growing medium and planting or repotting date.
- When changes began, root-ball moisture, frost history, last pruning and previous fertiliser or plant-care products.
Leaf colour alone does not prove iron deficiency. Root condition and soil reaction also affect nutrient supply. Identify coatings, webbing or recurring spots before choosing a suitable treatment.
Pests or disease: plant protection
Photographs of the whole plant and both leaf surfaces, with details of location, compost and watering, help identify problems.
