Hydroponics
Hydroponics requires product- and crop-specific instructions. The watering dilution above is not a guide for a permanent nutrient solution. This calculator therefore does not calculate hydroponic doses, EC targets or top-up amounts for this fertiliser concentrate. Please discuss the product and your hydroponic system with our advisers.
Contact our advisers →Irrigation system / fertilizer injector
Dosing units, irrigation systems and fertilizer injectors need settings suitable for the product and equipment. Plant size alone cannot determine pump settings, running time or a stock solution.
- Establish the actual water flow and intended running time.
- Check injection ratio, suction and product suitability against the equipment and product instructions.
- Prepare a flow test with clean water according to the equipment instructions. Do not use the normal watering dilution as continuous injection without checking its suitability.

Mixing with other productsMixing, combining or applying separately
Using products as part of the same care routine is different from mixing them in one container. Follow the labels and application instructions of all products involved.
- Tank mixing: Combine products in a watering can or spray tank only when the manufacturer instructions confirm the specific combination and use. Do not mix undiluted concentrates together.
- Separate application: Applying products separately or at different times does not automatically establish compatibility. Check the species, location, plant condition and instructions for both products. No universal waiting period follows from this.
- Complementary products: A recommendation for suitable growing media, accessories or another care product does not mean that it may be mixed with the fertiliser.
- Plant protection products: The crop, target organism, application method and pack instructions must also be suitable. The fertiliser calculator does not calculate plant protection product quantities or confirm compatibility.
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.

PRODUCT KNOWLEDGE
Apricot Fertiliser
Overview
Apricots in your garden
Suitable nutrient supply complements the light and watering care of your apricot tree.
Details & background
GREEN24 Apricot Fertiliser is a liquid NPK concentrate for apricot trees (Prunus armeniaca). The German names Aprikose and Marille on the front label refer to this plant. Dilute the concentrate with water before watering or spraying.
- Product form: liquid concentrate for root or foliar feeding.
- Pack sizes: 250 ml, or a 500 ml twin pack with two unchanged 250 ml bottles.
- Purpose: nutrient supply during the growing period; not a treatment for frost damage or fungal disease.
The twin pack provides a larger supply. Each bottle and its concentration remain unchanged, so the same volume of water does not require more concentrate.
Application
Measure, dilute and apply
Measure the amount required for Apricot Fertiliser according to its own label and add it to water. Mix well and apply during the specified growth period. The calculator and illustrated steps help with preparation.
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.
-
Clean the container
Clean the watering can, sprayer or bucket and rinse it with clean water.
-
Calculate the dose
Choose the amount of water you need and calculate the matching concentrate dose. The dosage calculator helps you do this.
Dilution: 5 ml per 1 l of water
Calculate the right amount → -
Add some water
Pour part of the calculated amount of water into the container first.
-
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.
Measure the concentrate using suitable millilitre graduations.
-
Add the concentrate
Pour the measured concentrate into the water already in the container.
-
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.
Application period: During the growing season
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 →Water first, concentrate second
Measure the required water volume. Then add the calculated concentrate volume and mix well. The amount of water and the concentration of the solution are separate quantities.
Roots or foliage
The label allows watering or spraying. Pre-water the root zone for soil application. For foliar feeding, follow the mandatory guidance on weather and open flowers. The label rate remains the basis for both application methods.
Young and sensitive plants
Leaflet 130405 recommends half strength for young and sensitive plants. Observe special dilution rates on a test plant first. A compact habit or a container alone does not make an established tree a young plant.
Nutrition & properties
Properties and plant care
Apricots need a warm, sunny position together with effective drainage. In containers, even moisture and sufficient root space matter particularly during growth and fruit development.
Details & background
Dilute this liquid concentrate with water before root or foliar feeding. Its own declaration, pack sizes and yield are listed in the product information.
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.
Select a point in the picture or choose a stage.
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.
Stage 02 / 04
Roots take up dissolved nutrients
Fine root hairs increase contact with the growing medium. Tiny transport proteins in the membranes surrounding root cells help dissolved nutrients enter the cells.
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
An inner layer controls the route
On their way into the root, nutrients meet a special layer of cells. It prevents substances from simply flowing through the gaps between cells and helps the plant control uptake.
Good to knowMore fertiliser does not automatically mean better nutrition.
A closer look
Nutrients move through the root tissues. The endodermis acts as a control layer: its barrier interrupts unrestricted movement along the cell walls.
Stage 04 / 04
Transport channels carry water and nutrients
Inside the root are fine transport channels called xylem. Water and absorbed nutrients can travel through them towards shoots and leaves.
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.
View original diagram ↗GREEN24 diagram with German labels
Stage 01 / 04
Diluted solution is applied to the leaf
For foliar feeding, diluted nutrient solution is sprayed onto the leaves. The product instructions tell you whether it is suitable for this use and how much to apply.
Good to knowSpray only as directed by the product instructions, never with undiluted concentrate.
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
Nutrients must cross the protective surface
The leaf surface protects the plant. Dissolved nutrients can pass through this layer; tiny openings in the leaf may also play a part. Uptake varies with the type of leaf and the conditions.
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
Cells inside the leaf take up nutrients
Behind the surface lies living leaf tissue. Its cells can take up nutrients that have crossed the surface and use them for their activities.
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
Nutrients are used in the leaf and may move onward
The plant can use absorbed nutrients within the leaf. Some can also reach other plant parts. This depends on the nutrient and the plant's condition.
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.

Care problems
For the intended nutrient supply
The product supplies nutrients to the plants identified on its label. Pre-fertilised growing medium and previous feeding already contribute to the overall supply and must be taken into account.
Investigate the need first
Changes in leaves, fruit drop or weak shoot growth are not enough on their own to determine a fertiliser amount. Record the growing position, moisture, previous care and observed changes for an informed consultation.
This fertiliser does not replace diagnosis of pest or disease problems, frost protection or suitable growing conditions. A higher concentration is not a general solution to plant damage.
Plant protection advice
The plant species, photographs and details of location, moisture and previous care help assess plant damage. Identify the cause and a suitable application before treatment.
More fertiliser is not a general solution to growing problems. A recommendation to buy products together does not confirm that they can be mixed.
Plant protection products and application
General manufacturer information: these products have not been selected here as suitable treatments for the plant shown here. Before use, check the plant species, pest, application site and current instructions.
Use plant protection products safely. Always read the label and product information before use.
Plant care
Plant profile
Care depends on whether your tree grows in garden soil, a container or as a trained fan. Choose the topic that matches your growing situation and task.
Growing from seed and keeping a cultivar
An apricot grown from a stone is a seedling, not a guaranteed copy of its parent. Fruit quality, growth and later yield may differ. Germination requires suitable moist cold treatment; a sowing experiment does not guarantee a crop.
To retain a particular cultivar, choose a named grafted plant. The rootstock influences vigour, among other characteristics. Label your own seedlings with their origin and sowing date so their development can be followed.
Experiences and horticultural sources
Start with experiences in the GREEN24 forum: Caring for young fruit trees (German) ↗ · Apricot from a stone (German) ↗. These are personal experiences; the guidance is checked against horticultural sources.
- Bavarian LWG: apricot position and pruning (German) ↗
- RHS: growing apricots in gardens and containers ↗
- RHS: protecting fruit blossom from frost ↗
- Utah State University: planting depth and roots ↗
- Penn State: growing fruit from seed ↗
Cultivar and site-specific decisions remain individual. Follow the GREEN24 concentrate’s own label and linked application leaflet.
Position
Position, cultivar and needs
Choose a sunny, warm, sheltered position with reliable drainage. Avoid low spots where cold air collects: early apricot blossom is particularly vulnerable to late frost.
For containers and small gardens, cultivar, rootstock and training method determine the space needed. Record these details and any fertiliser already in the growing medium. Weak growth or changes in leaves alone do not establish a need for extra feeding.
Water & growing medium
Watering: containers and garden soil
In a container: Keep the root ball evenly moist during growth without waterlogging it. Check especially in warm weather and as fruit develops; drainage holes must remain clear.
In the garden: Water newly planted trees thoroughly during dry spells. Rainfall and soil moisture determine any extra water needed by established trees. Water the root zone; a fixed daily schedule does not suit every soil.
Planting & repotting
Planting, repotting and growing medium
In the garden: Keep the root ball at its previous depth, with the graft union above the soil. Do not let exposed roots dry out, and water thoroughly after planting.
In a container: For long-term growing, use good-quality loam-based compost and a stable pot with drainage. Inspect root space regularly; densely crowded roots may need a slightly larger container. Account for fertiliser already present in the fresh compost.
Pruning & shaping
Pruning and training
For established apricots, plan maintenance pruning preferably just after harvest in summer. The Bavarian LWG identifies this as a favourable time for wound healing and light penetration. Fan-trained trees and free-standing crowns need different pruning methods.
Remove dead or damaged wood selectively and retain sufficient fruiting spurs. Young trees first need a sound framework. Plan major cuts with knowledgeable advice based on cultivar, tree condition and a photograph of the crown.
Overwintering & seasonal growth
Overwintering and blossom frost
Protect the container: Place it in a sheltered position and insulate the pot during frost to protect its roots. Water must still drain away. An unheated greenhouse is one option for overwintering small container-grown apricots.
Protect blossom separately: Cover small trees or trained fans with fleece when overnight frost is forecast. Keep the material clear of flowers and uncover during the day for light and pollinators. This is difficult to achieve with large garden trees.
Winter feeding and dormancy
Do not add this fertiliser during dormancy. Follow the growing period stated on its label rather than a universal date or the harvest date alone.
When problems appear, first examine moisture, roots, weather and previous care. Photograph the changes. Product-specific directions are collected under Application & dilution.
Frequently asked questions
Do Aprikose and Marille refer to the same plant?
Yes. The front label names apricot trees using both German names and the botanical name Prunus armeniaca.
Does the dilution change for the twin pack?
No. The twin pack contains two unchanged 250 ml bottles. Prepare the solution using the same label rate. A larger supply does not mean a stronger mixture.
How often is the fertiliser applied during growth?
The front label specifies application every two weeks during the growing period. It does not set fixed months for every location. Follow the plant’s condition, label and leaflet.
Can I spray it on the leaves?
The label provides for root and foliar feeding. Follow its instructions, particularly those about weather conditions and open flowers. The full guidance is under Application & dosage.
How far does a 250 ml bottle go?
At the standard label rate of 5 ml per litre of water, 250 ml of concentrate treats 50 litres of water. The twin pack treats a calculated 100 litres of water. Add the concentrate to the water in each case. This yield does not determine how much an individual tree needs.
Which water does the label recommend?
The back label specifies preferably lime-free water or rainwater at 15–25 °C. It does not give blanket approval for tap water of any hardness.
Does feeding replace treatment for fungal disease or frost damage?
No. This product is a fertiliser for nutrient supply. Establish the cause of infestation or damage first. Its nutrient declaration does not guarantee a cure or a particular frost tolerance.
Where are the mandatory application and storage instructions?
The leaflet is linked under Application & dosage. Product-specific safety and storage information is provided in the corresponding areas of this page.
