Hedge Plants
For deciduous and evergreen hedges. The catalogue group distinguishes broad-leaved plants, conifers and their different pruning limits.
Follow active growth
Every 2–3 weeks during active growth. April–September.
Consider the root zone
First ensure reliable watering and suitable soil structure for young hedges. Extra concentrate cannot remedy a dry root ball, compaction or excessively deep pruning. Keep the base of a clipped hedge slightly wider than the top.

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.
Account for water quality and existing nutrients. The dilution does not establish a fixed soil or prepared-solution pH.
Use clean, suitable watering or spraying equipment. Measure the water and calculated concentrate quantity carefully.

GREEN24 · Plant knowledge
Green rooms that grow with the garden
A narrow formal hedge is regularly controlled. Informal flowering hedges need more width and a different thinning approach.
Leaves and needles
Distinguish deciduous, semi-evergreen and evergreen species. Brown retained hornbeam leaves in winter are not automatically damage.
Growth and care
Equal hedge height does not mean equal pruning tolerance. Thuja and false cypress often regrow poorly from brown old wood.
The root zone
Water the whole root-ball area of newly planted hedges. Check moisture below the surface and water deeply as needed; established hedges mainly need attention during prolonged drought.

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, leaves and new shoots
Roots · absorb and anchorFine, shallow roots take up water and dissolved nutrients.
Assess root space, moisture and aeration for the actual species. Allow recovery after root work; do not assume one soil pH suits all woody plants.
Leaves · capture energySimple leaves use light to make sugars; winter foliage depends on species.
Yellow leaves with green veins warrant checking soil reaction, water and roots. This alone does not identify a specific deficiency or justify a higher dose.
Shoots · support & connectWoody branches carry leaves and terminal buds.
Choose pruning timing and extent for species and vigour. Woody plants differ in their ability to regrow from old wood.
How nutrients enter your hedge plants
Select a point in the picture or choose a stage.
Stage 01 / 04
The solution reaches the 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 the nutrition of your hedge plants.
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 the nutrition of your hedge plants.
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 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 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 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 plants and establishment
Allow newly planted or root-worked woody plants to establish first. Account for starter nutrients and root condition.
Leaf growth and bud formation
Every 2–3 weeks during active growth. April–September.
Dormancy and winter care
Check evergreen hedges for dryness in winter too. Young plants are less deeply rooted than established hedges.
Species, position and active growth determine the care routine.
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.
Site and growing conditions for hedge plants
Pots · moisture and rooting space
Water the whole root-ball area of newly planted hedges. Check moisture below the surface and water deeply as needed; established hedges mainly need attention during prolonged drought.
Borders · account for soil reserves
Choose species and mature space requirements first. Consider compaction, waterlogging and persistent root competition from nearby trees.
Winter · consider the species’ rhythm
Check evergreen hedges for dryness in winter too. Young plants are less deeply rooted than established hedges.
Repotting & pruning · match the species
Choose timing by species and growth, checking medium and drainage. Follow the full instructions for the linked growing medium.
Understand care problems
Position & water first
Choose species and mature space requirements first. Consider compaction, waterlogging and persistent root competition from nearby trees.
Recognise pests
Assess damage by species; box-tree moth affects box, not every hedge.
Assess damage
Inspect isolated brown plants for root health, soil moisture and fungal disease. Establish the cause before choosing action.
Discuss the care problem
These details help assess growing conditions, root problems or a possible infestation:
- Tree species and photographs of the whole plant and affected parts.
- Position, delivery form, root space and recent care.
- Watering routine, moisture, fertiliser and amounts already used.
Chlorosis can be associated with unsuitable soil pH or damaged roots. Have leaf spots and bud problems identified; adding more fertiliser is not a diagnosis.

Quick answers before you buy (FAQ)
How much prepared feed does each pack make?
250 ml → 125 l, twin pack → 250 l, 1 litre → 500 l. Calculated from the stated dilution; plant needs determine the amount applied.
Can every hedge be cut back into old wood?
No. Yew and many broad-leaved hedges respond differently from thuja or false cypress. Identify the species before major pruning; nutrients cannot replace the ability to regrow.
Should I feed immediately after repotting?
Account for initial nutrients in the compost and root condition. After root disturbance allow recovery, then match further feeding to growth and the label.
How do I prepare a small amount?
5 ml per 2.5 litres of water. Use a suitable measuring tool and shake the concentrate before use.
Can I use different plant care products together?
Follow the mixing information on this product page and the directions for all products involved. Plant, target organism and application method must match the specific combination.
