A rough guide for root watering of one leafy plant, not foliar spraying. Measure height from ground level and crown or bush width. Check roots, soil moisture and weather; for large trees, trained forms, cane rows and leafless dormancy, enter the actual water volume.
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 standard dilution. The estimate 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. When using the size-based guide, also check root space and actual root-ball moisture.
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? 10 ml per 2.5 litres of water. Apply every 1–2 weeks during active growth. For 5 litres of water use 20 ml, or 40 ml for 10 litres. Six illustrated steps show the process. Distribute diluted solution in the pre-moistened root zone. Account for drainage and previous nutrient applications. The label allows spraying foliage; avoid open flowers. Do not apply in sun, below 5°C or above 30°C.
Watering · through the roots
Pre-moisten the root zone and distribute the mixture evenly over the rooted area. Excess water must drain from containers. Trunk height or the length of a raspberry row alone does not determine the required water volume.
Spraying · onto the leaves
Finely wet existing foliage in the morning, evening or under overcast skies; avoid open flowers. Foliar feeding belongs to the same nutrient plan as root feeding, not an automatic addition. Different fruit species have different leaf surfaces.

Fits your care routine
For fruit trees and berries
For fruit trees and berry bushes in gardens and containers. Choose further care for the particular species, cultivar and rootstock where applicable.
During active growth
During active growth, normally April–September. Consider soil moisture, season and existing nutrients together.
Each pack has its own directions
After planting or repotting, account for pre-fertilisation in the compost. If roots are dry or damaged, address growing conditions first.
Beyond NPK · understand the formulation
Well mixed – available to leaves and roots
Water-soluble nutrients and formulation properties supplement the nutrition of growing fruit trees and berry bushes. The diluted mixture can be applied to the root zone or existing foliage.
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
The formulation helps reduce adverse hard-water effects and deposits on the leaves. Low-lime water or rainwater provides a good starting point.
Feed with plant tolerance in mind
High plant compatibility when applied correctly supports feeding in the fruit garden and containers. Suitable rooting conditions, light and moisture remain separate requirements.
Understand leaf quality and fruit development
Nutrients contribute to leaf formation, metabolism and fruit development. Leaf finish describes a well-kept appearance, not an applied glossy film. This does not imply a fixed crop, sweetness or ripening outcome across fruit species.
Chelation can reduce interfering effects of water hardness; it does not remove calcium and magnesium from the water. The product pH of 6.8 describes the concentrate, not the soil. Source water influences the pH of the prepared mixture; no fixed target value is promised.
Use clean, suitable watering or spraying equipment. Measure the water and calculated concentrate quantity carefully.

GREEN24 · Plant knowledge
Leaves. Blossom. Ripening fruit.
Apple trees, apricots and currant bushes express the seasons in different ways. Observe new growth, blossom and fruit development on your own plant. The images and drawings show individual examples from this varied group.
Leaves supply the plant
Leaves use light to produce sugars for growth and maintenance. Apples, raspberries and currants differ in leaf structure and emergence. The garden species covered here are mostly deciduous.
Distinguish blossom and pollination
Stone fruit may flower before leaf emergence, with other fruit types following later. Many fruit flowers are pollinated by insects. Whether another compatible cultivar is required depends on the species and cultivar, not simply on being a fruit tree.
Observe fruit development
Pome fruit, stone fruit and berries develop different fruits and ripening seasons. Water, light and supply from the leaves contribute to development. Consistent care does not promise a particular fruit count or harvest date.

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.
How fruit trees and berry bushes use nutrients
Roots · uptake & anchorageFine root areas access water and dissolved nutrients.
Absorbing fine roots need contact with moist, aerated soil. This space is limited in containers; in open ground it also depends on soil and rootstock. Blueberries require a separate acidic root environment.
Shoots & wood · framework and connectionSupport leaves and fruiting wood and connect the above-ground parts with the roots.
Trunks and branches form the framework of trees; berry bushes often have several basal stems or canes. Conducting tissues connect these parts. Fruiting-wood age differs: summer and autumn raspberries and black and red currants do not share one pruning routine.
Leaves · turning light into sugarsLeaf surfaces produce sugars that support growth and fruit development.
Nutrients support metabolism in leaves but cannot replace light. Leaf size and structure differ considerably between pome fruit, stone fruit and berries. For mostly deciduous garden species, autumn leaf fall is seasonal; early leaf loss needs separate assessment.
Fruit · development and ripeningReceive water and substances from the plant; fruit form and ripening differ by species.
Sugars from the leaves and suitable water and nutrient supply contribute to fruit development. Apples, cherries and raspberries form botanically different fruits. Extra fertiliser cannot replace suitable pollination or restore damaged flowers.
How nutrients enter your fruit plant
Select a point in the picture or choose a stage.
Stage 01 / 04
Nutrient solution reaches fine roots
In pre-moistened soil, the diluted mixture meets fine root areas. Dissolved nutrients are available for uptake at the contact surface.
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.
Stage 02 / 04
Uptake at the root surface
Fine root hairs increase contact with the soil. Transport proteins in cell membranes help take up dissolved nutrients.
Good to knowRoots take up nutrients; they do not simply absorb all the fertiliser along with the water.
A closer look
Root hairs increase the contact area. Transport proteins in cell membranes enable mineral ions to enter; water movement and nutrient uptake are distinct processes.
Stage 03 / 04
Living root cells regulate uptake
Dissolved nutrients pass through controlled steps in living root cells. The plant is not simply flushed with the entire contents of the watering solution.
Good to knowMore fertiliser does not automatically mean better nutrition.
A closer look
Controlled steps within root tissue lie between the root surface and onward transport. Transport across cell membranes enables nutrient uptake; water movement and nutrient uptake are different processes.
Stage 04 / 04
On to shoots and leaves
Water and absorbed nutrients can move through the xylem to above-ground parts. Healthy roots and active leaves are part of this process.
Good to knowHealthy roots and suitable growing conditions are important for nutrient supply.
A closer look
After entering the vascular tissue, nutrients can travel with the water stream in the xylem towards the shoot. Uptake and nutrient supply also depend on root health and growing conditions.
Stage 01 / 04
The solution wets existing leaves
The diluted mixture contacts the leaf surface. Apply in the morning, evening or under overcast skies, avoid open flowers and observe the temperature limits.
Good to knowThis concentrate is also suitable for foliar application. Use only diluted and include it in the combined feeding plan.
A closer look
Foliar feeding places diluted nutrient solution on the leaf surface. Wetting depends on factors including the leaf surface and the solution.
Stage 02 / 04
Crossing the protective leaf surface
Dissolved nutrients can cross the protective surface layer; routes involving small leaf openings may also contribute. Conditions and leaf characteristics affect uptake.
Good to knowDifferent leaves do not absorb a nutrient solution equally well.
A closer look
Dissolved nutrients can pass through the protective cuticle; pathways involving stomata may also contribute. Their relative importance varies with plant species and conditions.
Stage 03 / 04
Living leaf cells take up nutrients
After crossing the surface, living leaf cells can take up nutrients and use them in metabolism. A visible droplet alone does not demonstrate this step.
Good to knowA droplet on a leaf does not yet mean its nutrients have been absorbed.
A closer look
After crossing the surface, nutrients can be taken up by living leaf cells. The amount depends on factors including the nutrient, formulation and environmental conditions.
Stage 04 / 04
Use in the leaf and onward movement
Absorbed nutrients can be used in the leaf or redistributed, depending on the nutrient. This does not mean immediate uniform supply to every fruit or shoot.
Good to knowFoliar feeding does not mean every nutrient immediately reaches the whole plant.
A closer look
Absorbed nutrients can be used within the leaf. Whether and how far they move to other plant parts depends on the nutrient and the plant's condition.
Development influences requirements
Establishment, growth and winter dormancy
Young and newly planted fruit plants
First establish root contact, suitable moisture and stability. Fresh pre-fertilised growing medium counts towards nutrition. Small height does not create an additional concentration stage; this product has one standard dilution stage.
Foliage, blossom and fruit development
During growth, observe new leaves and shoots, blossom and fruit set. Timing differs between early stone fruit, pome fruit and berry bushes. Coordinate feeding at the specified interval with soil moisture and existing nutrients.
Winter · dormancy in garden fruit
Most garden fruit species covered here shed their leaves in autumn. Pause feeding during dormancy while continuing to check container moisture. Winter hardiness and sensitivity to blossom frost differ; plan protection for the species, cultivar and site.
Consider cultivar, season, roots and existing nutrients together. Height determines neither a different dilution nor individual water demand.
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.
Where do your fruit plants grow?
Container · moisture & drainage
Use a stable container with drainage holes and sufficient root space. Its limited root ball can dry faster in summer than garden soil. Check moisture regularly and include existing pre-fertilisation when planning further feeding.
Open ground · root space and rootstock
Provide sufficient rootable, drained soil and room for the mature plant. Sunny, airy sites are usually suitable; consider local frost pockets. For grafted trees, choose planting depth with the plant and graft union in mind.
Distinguish winter cold and blossom frost
Container roots are more exposed to cold than roots in garden soil. For hardy garden species, protection depends on the container and position. Open flowers may later be more sensitive than dormant wood; watch local frost forecasts.
Espaliers, columns & canes · suitable training
Training and pruning depend on species and fruiting wood. Apples and pears are not a universal pruning template for stone fruit or berries. For flat-trained forms and cane rows, enter actual water volume rather than treating wall or bed area as a single crown.
What is changing on your fruit plant?
Aphids and distorted shoot tips
Inspect leaf undersides and young shoots. Assess aphids, visiting ants and curled leaves together, while watching for beneficial insects.
Spots, coatings and fruit rot
Scab, mildew and fruit rots look different between fruit types. Photograph affected parts and the whole plant; remove diseased mummified fruit during maintenance.
Flowers but few fruits
Late frost, inadequate compatible pollination, drought or natural alternating crop levels may be involved. Extra fertiliser does not automatically solve these causes.
Yellow leaves and stalled growth
For blueberries, check the acidic root environment first; for all types, assess excess moisture, drought and root damage. A visible symptom alone does not determine a fertiliser dose.
Advice for fruit trees and berry bushes
These details help assess growth, fruit development and possible damage:
- Photographs of the whole plant, young shoots, both leaf surfaces and affected fruit; include unusual bark or roots.
- Species, cultivar and rootstock if known; age, tree or bush form, container or open-ground culture and growing medium.
- Flowering time, frost events, moisture changes, pruning date and previous feeding. Describe when the change started.
A single symptom proves neither a deficiency nor a particular disease. Check acidic rooting conditions separately for blueberries. Poor fruit set can also result from blossom frost or unsuitable pollination conditions.

Quick answers before you buy (FAQ)
How should I dilute this fertiliser?
10 ml per 2.5 litres of water. Apply every 1–2 weeks during active growth. The front label gives April to September as the regular application period.
Does the litre pack have the same recipe?
The main NPK figures match, but the original declarations differ for manganese, zinc and the storage limit. The 250 ml and XL products therefore remain separate articles with their own instructions.
How much solution can I prepare?
At 10 ml per 2.5 litres of water, 250 ml treats 62.5 litres of water and two bottles treat 125 litres. This is the calculated label amount, not a second dilution stage.
Will extra feed solve poor fruit set?
Inadequate pollination, blossom frost, unsuitable pruning or drought can limit fruit set. Investigate first. An extra feed does not replace identifying the cause.
Can I feed immediately after repotting?
Fruit Plant Compost already contains nutrients. Its label calls for supplementary feeding to begin after 4–6 weeks. Account for growth and existing nutrient supply.
Is Fruit Plant Compost also suitable for blueberries?
Not automatically: blueberries require acidic rooting conditions. Choose a suitable acidic compost for them; the linked Fruit Plant Compost is an option for suitable other fruit and nut trees.
