Dilution calculator for conifers

Dilution: 5 ml per 1 l of water.

Your water amount
1 l
Matching concentrate amount
5 ml

1 capful = 5 ml. Use a suitable measuring aid for smaller partial amounts.

  1. Prepare a clean container

    Use a clean watering can or sprayer; preferably low-lime water or rainwater at 15–25 °C.

  2. Calculate the amount

    Enter the water volume or measure one conifer. For hedges, calculate from the actual water volume. Check root-ball moisture and drainage before watering.

  3. Add some water first

    Start by filling the container with part of the chosen water volume.

  4. Shake & measure

    Shake the bottle. 1 capful = 5 ml; use a measuring aid for smaller partial amounts.

  5. Add the concentrate

    Add the calculated amount of concentrate to the water.

  6. Top up & mix well

    Top up to the chosen water volume and mix well. Watering or spraying: see below.

When to feed? 5 ml per 1 l of water. Every 3–4 weeks during the growing season. Regular application period: April–August.

Watering · through the roots

Pre-moisten the root ball and distribute the solution through the absorbing root zone. Do not water only immediately beside the trunk. Ensure drainage in containers; address the cause of waterlogging or drought-damaged roots first.

Spray · onto needles or scale leaves

Finely wet needles or scale leaves in the morning, evening or under overcast skies, avoiding open flowers. Foliar feeding belongs to the same nutrition plan as root feeding. A different leaf shape does not justify a higher spray concentration.

For your conifers

For the conifer group

For conifers with needles or scale leaves. Genus and cultivar determine the further growing plan; Ginkgo and indoor Norfolk Island pines are not included under a single shared care description.

During active growth

During active growth, normally April–August. Account for soil nutrients, fresh compost and previous applications.

In containers and gardens

Fresh compost may already contain fertiliser. After planting or repotting, account for its initial nutrients and root condition when planning further feeding.

Beyond NPK · understand the formulation

Well mixed – available to leaves and roots

Water-soluble nutrients and formulation properties support mineral nutrition in conifers. The diluted solution can be applied to the root zone or to needles and scale leaves.

Water-soluble & available

All nutrients are water-soluble. In the fully diluted mixture, they are available for feeding through roots and leaves.

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 adhesion help distribute the spray solution over needles and scale leaves. Dissolved nutrients are available there for foliar uptake; wetting alone does not establish how much has been absorbed.

Reduce hard-water effects

The formulation helps reduce unwanted effects of hard water and deposits on needles and scale leaves. Low-lime water or rainwater provides a useful starting point.

Feed with plant tolerance in mind

High plant compatibility under appropriate use is relevant to sensitive crops too. The specified dilution and protection from sun and heat remain important for young conifer shoots.

Understand leaf function and growth

Nitrogen is needed to build chlorophyll and proteins, phosphorus for energy transfer, and potassium for water regulation and transport. These functions concern needles and scale leaves as well as growing roots and shoots. Well-maintained foliage does not mean a promised colour; blue, golden and deciduous cultivar characteristics still matter.

Chelation can reduce unwanted hard-water effects; it does not remove calcium or magnesium from the water. Product pH 6.8 describes the concentrate, not the soil or a fixed target pH for the finished solution. The starting water also influences the solution’s pH.

Use clean, suitable watering or spraying equipment. Measure the water and calculated concentrate quantity carefully.

Products

Use other care products according to their own instructions. A product recommendation does not confirm tank mixing.

Do not mix undiluted concentrates. Follow each product’s own application method and dose.

GREEN24 · Plant knowledge

Needles. Scale leaves. Different growth habits.

Pines carry needles, while thuja usually has closely overlapping scale leaves. Cushion forms, columns and large trees need different amounts of space. Many conifers are evergreen; larch, dawn redwood and bald cypress shed their foliage in autumn.

Cone-shaped green conifer with dense scale-like foliage in a mulched bed beside a paved garden path.

Needles are leaves

Pine needles occur in bundles whose number varies by species; larches carry softer needles and are deciduous. Old inner needles can change colour during normal foliage renewal. Dying shoot tips or larger brown patches need a separate assessment.

Scale leaves form dense sprays

Thuja and many members of the cypress family have small, overlapping scale leaves. Green outer shoots need light. Do not routinely cut into old bare wood; the ability to regenerate differs between genera.

New shoots and natural habit

New shoots extend the leafy crown. Dwarf pines, columnar thuja and large larches grow at different rates and widths. Natural habit is not a reason to increase fertiliser concentration.

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 do conifers use nutrients?

Conifer with roots, trunk, foliage and young shoots 1234
Roots, woody framework, green foliage and new shoots work together. Needles and scale leaves are different conifer characteristics; not every genus is evergreen.
Roots · absorb and anchorAbsorbing roots access soil water and dissolved nutrients.

Moisture and oxygen must both be available around the roots. Soil requirements differ between conifer species. Mycorrhizal fungi help many conifers interact with the soil; the ectomycorrhiza common in pines is not one uniform model for every conifer genus.

Woody framework · support & conductThe trunk and branches support the crown and connect roots, foliage and shoots.

Xylem carries water and dissolved substances upwards. Sugars from green foliage move through other conducting tissue to growing or storage tissues. A leading shoot is part of many upright forms; routine topping is not a necessary feeding or care measure.

Needles & scale leaves · use lightNarrow needles and small scale leaves also carry out photosynthesis.

Nitrogen is part of chlorophyll and proteins; iron and manganese have further metabolic roles. Leaf shape and protective surfaces differ between genera. Bluish or golden cultivar colour and normal foliage renewal are not automatically signs of deficiency.

Young shoots · continue growthNew shoots extend the leafy crown according to species and cultivar.

New cells require nutrients and sugars made by the plant. Phosphorus contributes to energy transfer. Growth rate and regeneration also depend on the genus: yews can reshoot from older wood, while many thuja and cypresses do not reliably regrow from bare old sections.

A closer look

Development influences requirements

Distinguish establishment, new growth and rest

Establishment & young conifers

After planting, even root-ball moisture, soil contact and protection from drying wind matter. Account for pre-fertilised compost and existing nutrients. No additional young-plant dilution setting is verified for this concentrate.

Needle, scale-leaf and shoot development

Feed at the specified interval during active growth. Dwarf forms naturally grow more slowly than tree-sized conifers. Do not try to change their growth habit through extra or more concentrated applications.

Resting period · with or without green foliage

Green winter foliage does not automatically mean active growth. Do not fertilise during rest, but check root-ball moisture in frost-free weather. Autumn foliage loss is normal in larch, dawn redwood and bald cypress.

Genus, cultivar and foliage age help interpretation. Compare normal inner foliage renewal with new damage to outer shoots. Seasonal changes do not establish an additional dilution setting.

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.

Specimen, hedge or container?

Container · account for limited root space

Use a pot suited to the plant’s habit with open drainage holes. Check root-ball moisture regularly without keeping every conifer equally wet. Account for initial nutrients and planting depth when repotting; fertiliser concentration remains unchanged.

Garden · match species and soil

Choose light, soil moisture and future space according to species: pines generally prefer sun, while yews tolerate shade. Maintain the original planting depth. Established conifers in adequately supplied soil do not automatically need regular supplementary feeding.

Winter · consider site and origin

Hardiness is not uniform across the group. Hardy outdoor species stay outside; more tender Mediterranean cypresses need protection suited to the region. Protect container roots from severe freezing and do not leave evergreen foliage over a dry root ball. Norfolk Island pines need their own indoor care plan.

Hedge · retain the green outer growth

For suitable hedge forms, a narrower top helps light reach the lower branches. Do not cut thuja and many cypresses deeply into bare old wood. Yews are an important exception in their ability to regenerate. Check for occupied bird nests before clipping.

What is changing on your conifer?

Needle renewal or stress?

Older inner needles are naturally replaced. Large brown patches and wilting shoot tips instead call for a check of soil moisture, drying winds, frost and previous pruning.

Conifer aphids

Inspect shoots for aphids, sticky honeydew and dark sooty mould. Green spruce aphid can damage older spruce needles, especially after mild winters; identify both plant and pest.

Scale insects on scale foliage

Check junipers, cypresses and arborvitae for small attached pale or brown scales. Not every deposit signals a severe infestation; juniper scale does not produce honeydew.

Damaged roots

If a plant fades and browns despite wet soil, inspect drainage and roots. Waterlogging and root diseases such as Phytophthora can look alike; reliable identification may require specialist diagnosis.

Advice for your conifer

These details help distinguish normal foliage renewal, site problems and possible pests:

  • Photos of the whole plant or hedge section, damaged and healthy shoots for comparison, needles or scale leaves, and the base of the trunk.
  • Genus and cultivar, planting date, specimen or hedge, pot or garden, soil, light, wind and whether neighbouring plants are affected.
  • Onset and spread, soil moisture, recent drought or frost, timing and depth of pruning, and previous fertiliser and care products.
Request advice for my conifer

Individual yellow or brown needles do not establish a deficiency. Check roots and soil when larger sections fail; identify aphids or scale insects before treatment. The mixing partners below are not automatically authorised for every conifer species or problem.

Quick answers before you buy (FAQ)

Which pack size suits me?

At the stated dilution, 250 ml makes a calculated 50 litres of fertiliser solution. The twin pack of two 250 ml bottles makes 100 litres; 1 litre of concentrate makes 200 litres. The concentration is the same.

How often should I feed conifers?

The original labels specify every three to four weeks during active growth, with April to August as the regular period. Feed when needed and account for nutrients already supplied by fresh compost.

Will fertiliser fix brown needles?

Brown needles alone do not establish nutrient deficiency. Drought, wet roots, frost, pruning damage and pests are other possibilities. Autumn needle loss is normal in larches and dawn redwoods. Identify the species and pattern first.

Should I feed roots and foliage at the same time?

The label permits both routes. Choose the one suited to the situation and account for every application. Foliar feeding is not an extra standard dose on top of routine root feeding.

Can every conifer use the same compost?

Water and soil requirements depend on the species. The linked Tree & Shrub Compost is a general growing medium; it does not replace choosing the right site or ensuring drainage. Specialist cultivation such as bonsai needs its own root environment.

Diesen Dünger nutze ich schon seit Jahren mit überwältigendem Erfolg für alle meine Nadelbäume, Koniferen und Zypressen. Selbst sehr sparsame Anwendung führt zu sichtbarem Wachstum und sattgrünen Trieben. Rechtzeitig im Spätsommer stelle ich die Düngegaben ein, damit die Gehölze für den Winter ausreifen können. Ich hatte noch nie Frostprobleme. Wenn sich die ersten Triebe im Frühjahr zeigen, fange ich wieder an zu Düngen. Diese Lärche (auf dem Bild) habe ich nach Erhalt mit dem Koniferendünger von Green24 gedüngt und sie ist daraufhin sehr freudig gewachsen, ist nochmal stark durchgetrieben, und hat sogar viel größere Nadeln bekommen. Aber jetzt zum Herbst hin hat sie Winterknospen entwickelt und wirft jetzt auch allmählich die Nadeln ab. Genau, wie es sein soll. Insgesamt bin ich äußerst zufrieden mit dem sehr ergiebigen Koniferendünger von Green24.

Ich verwende diesen Dünger für im Herbst 2016 gepflanzte Smaragd Thuja(ca. 160cm hoch) und bin damit bisher zufrieden. Mit dem Koniferen Dünger XL Profi Linie 1 muss ich nur alle 3 Wochen düngen, mit dem preisgünstigeren auch guten Dünger von der BayWa jede Woche, hatte also 3 mal mehr Arbeit. Durch das wöchentliche Düngen entstehen mit dem preisgünstigen Dünger die gleichen Kosten wie mit dem Koniferen Dünger XL Profi Linie 1, den ich nur alle 3 Wochen verwende.

Habe das Produkt gekauft weil meine, im letzten Jahr gepflanzten, Smaragdthujen kein Wachstum erkennen ließen.
Der Dünger wurde sehr schnell geliefert und war ordentlich verpackt.
Nach dem Kauf bekommt man vom Händler eine E-Mail mit diversen Hinweisen und Anwendungsbeispielen.
Ich habe dann 1x im Monat meine Thujen mit dem Dünger gegossen ( man kann die Thujen auch damit besprühen, so das der Dünger über die Blätter aufgenommen wird ). Im 3. Monat - ich hatte schon nicht mehr daran geglaubt, begannen die Thujen plötzlich an den Spitzen auszutreiben!!
Somit scheint das Produkt seine Arbeit zu machen - ist zwar nicht billig, aber ich werde diesen Dünger sicher wieder kaufen und verwenden!!
