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 actually needed. 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? Every 1–2 weeks during growth, normally April/May to September. Account for existing fertilisation.
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
Spray the diluted solution finely onto leaves, avoiding open flowers. Do not apply in sunshine; account for root and foliar applications together.

Does this fertiliser suit your plant?
Identify your plant
For boxwood; the manufacturer also lists small hollies. Check soil requirements separately.
Use during growth
Use during active growth when additional nutrients are needed; account for pre-fertilisation and previous applications.
Consider the root zone
Account for fertiliser in fresh compost after repotting. Begin extra feeding according to need and existing nutrients.
Beyond NPK · understand the formulation
Well mixed – available to leaves and roots
The concentrate supplies declared major and trace nutrients. At the correct dilution it can be applied through the root zone or foliage.
Protected trace nutrients
Copper, iron, manganese and zinc are declared as EDTA chelates. This binding helps keep these trace nutrients available in solution.
Reduce hard-water effects
Prefer low-lime water or rainwater at 15–25 °C for mixing. Assess the actual soil reaction separately.
Measure accurately and feed to need
The label dilution applies to watering and spraying. More concentrate cannot replace suitable growing conditions.
Nutrients and plant development
Nitrogen contributes to chlorophyll and proteins, phosphorus to energy transfer and potassium to water regulation. Growth also depends on light, water and healthy roots.
Copper, iron, manganese and zinc are declared as EDTA chelates. Product pH 6.9 describes the concentrate, not a guaranteed soil pH.
Use clean, suitable watering or spraying equipment. Measure the water and calculated concentrate quantity carefully.
Products
Pre-fertilised soil and previous applications count towards total nutrient supply. No specific tank-mix partner is approved in these packages. Apply other products separately according to their own labels.
Combine with another product only when both sets of directions explicitly allow it. Otherwise apply separately.

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.
Roots, shoots, leaves and flowers
Roots · absorb and anchorFine roots need water and oxygen for uptake.
Provide adequate root space and even moisture. Address waterlogging or a dry root ball first; higher concentration cannot compensate for root damage.
Trunk and branches · support and connectionWoody axes support the crown and contain conducting tissue.
Clipping maintains the desired outline. Check plant condition and root-ball moisture afterwards.
Leaves – using lightSmall opposite leaves form a dense evergreen crown.
Inspect leaves and young shoots inside and outside the crown; do not automatically treat unusual colour as nutrient deficiency.
Flowers – reproductionSmall yellowish flowers occur in the leaf axils.
Frequent clipping can remove flowers. Flower numbers do not determine a different dilution.
How nutrients enter your boxwood
Select a point in the picture or choose a stage.
Stage 01 / 04
The solution reaches the boxwood 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 boxwood'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 boxwood'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 boxwood leaves
After uptake, water and nutrients pass through conducting tissue to aerial plant parts. Growing conditions influence development.
Good to knowConducting tissue connects roots and new shoots. Development also depends on growing conditions.
A closer look
Xylem transports water and dissolved substances. Root health and growing conditions affect transport; leaf colour alone does not establish nutrient status.
Stage 01 / 04
The solution wets the boxwood 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 boxwood leaf surface
The leaf blade has a protective surface. Dissolved nutrients can cross it; leaf age and application conditions affect uptake.
Good to knowLeaf or plant size alone does not justify a higher concentration.
A closer look
Nutrients can cross the protective cuticle; stomatal routes may contribute depending on conditions. The illustration is a functional diagram, not a species-specific tissue section.
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
Redistribution depends on the nutrient and plant condition. Foliar feeding does not guarantee a particular growth rate or flowering.
Good to knowFoliar feeding does not replace healthy roots or checks of light and water.
A closer look
Whether and how far nutrients are redistributed from a leaf varies by nutrient. This does not establish immediate feeding of the whole plant.
Development influences requirements
Distinguish establishment, growth and dormancy
Young tree and new planting
Check root condition and existing feed. These labels do not specify a separate young-plant dilution; do not import factors from another product.
Active growth
During active growth, assess water demand, roots and existing nutrients. Height growth alone does not justify a stronger solution.
Dormancy and winter care
Do not feed routinely outside active growth; follow the label period.
Consider species, growth stage, root condition and existing nutrient supply together. Plant height alone does not determine the dose.
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.
Boxwood in borders and containers
Pots · moisture and rooting space
A sufficiently large container needs clear drainage holes. Water evenly as needed without keeping the root ball saturated; check moisture before watering again.
Borders · account for soil reserves
Plan adequate long-term clearance and root space. Check soil nutrient supply and moisture before adding nutrients.
Winter · consider the species’ rhythm
Protect container roots from sharp temperature changes and check moisture. Winter discolouration is not clear proof of nutrient deficiency.
Repotting & pruning · match the species
Provide suitable root space and drainage. Account for starter feed in fresh compost before adding fertiliser.
What is changing on your boxwood?
Spot box tree moth
Look inside the shrub for caterpillars, webbing and frass. Check repeatedly and assess the extent of damage.
Distinguish leaf and shoot damage
Leaf spots, rapid leaf fall and dark stem streaks can indicate box diseases. Wet foliage and dense poorly ventilated growth encourage problems.
Check winter and drought stress
Bronzing alone does not prove nutrient deficiency. Consider moisture, frost, sun and the timing of the last trim.
Advice for your boxwood
These details help assess growing conditions, root problems or a possible infestation:
- Photos of the whole plant, affected leaves, shoots and root zone.
- Species/cultivar, garden or container, light, substrate and planting date.
- Timeline, moisture, frost and previous fertilisers or care products.
Discolouration alone does not prove nutrient deficiency. Identify the cause before changing care.

Quick answers before you buy (FAQ)
Does my box ball need a stronger mix than a hedge?
The label specifies 5 ml per 2.5 l water, regardless of clipped shape. The amount of solution depends on actual use.
Can I also use it for small hollies?
The manufacturer also lists small hollies. Boxwood and holly are different plants; choose compost for the actual species.
How often should I feed during active growth?
Follow the label: every 1–2 weeks during active growth, normally April/May to September. Account for existing feed.
How much solution do 250 ml and 1 litre make?
At 5 ml per 2.5 l, 250 ml makes a calculated 125 l and 1 litre 500 l of fertiliser solution.
Do I have to spray the boxwood leaves?
No: the label allows watering or spraying. Pre-moisten the root zone before watering; avoid open flowers when spraying.
