Water-soluble & available
All nutrients are water-soluble. In the fully diluted mixture, they are available for feeding through roots and leaves.
Conifers include trees and shrubs with needles or scale leaves. Pines, thuja, yews and larches differ in habit, foliage retention and site requirements. This guide connects use of the concentrate with knowledge for your particular garden or container plant.
Application in one place
Dilution: 5 ml per 1 l of water.
1 capful = 5 ml. Use a suitable measuring aid for smaller partial amounts.
Enter a water amount from 0.1 to 1,000 litres.
A rough root-watering guide for one conifer only. Measure height from soil level and the full leafy crown width, not individual needles or trunk circumference. For a hedge, enter the actual water volume. Check moisture, soil, roots and weather; do not force the suggested volume. This is not a foliar spray volume.
General GREEN24 guide: height (m) × width (m) × 3–4 litres. Centimetres are converted to metres. The concentrate amount follows this fertiliser’s dilution. The guide does not measure individual water requirements.
Use a clean watering can or sprayer; preferably low-lime water or rainwater at 15–25 °C.
Enter the water volume or measure one conifer. For hedges, calculate from the actual water volume. Check root-ball moisture and drainage before watering.
Start by filling the container with part of the chosen water volume.
Shake the bottle. 1 capful = 5 ml; use a measuring aid for smaller partial amounts.
Add the calculated amount of concentrate to the water.
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.
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.
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.
Net mass: 273 g for 250 ml; 1094 g for 1 litre.
The dilution is the same for both pack sizes.

Yield at the labelled standard dilution; account for pack size and existing nutrients.
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, normally April–August. Account for soil nutrients, fresh compost and previous applications.
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
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.
All nutrients are water-soluble. In the fully diluted mixture, they are available for feeding through roots and leaves.
Copper, iron, manganese and zinc are declared as EDTA chelates. This binding helps keep these trace nutrients available in solution.
The buffer system helps regulate the pH of the finished watering or spraying solution. The source water also influences the resulting value.
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.
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.
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.
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.
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.
Declared nutrient percentages. Product pH: 6.8.
GREEN24 · Plant knowledge
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.

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.
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 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.

Leaves use light; roots take up water and mineral nutrients. The diagrams show how plant organs work together and how nutrients are absorbed.
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.
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.
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.
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.

After crossing the surface, leaf cells can take up nutrients and use them in metabolism. Nitrogen, phosphorus and potassium have different roles. A visible drop does not itself prove uptake.
Good to knowCultivar colour and natural shedding of old needles must still be distinguished from deficiency.

Redistribution from foliage depends on the nutrient and plant condition. Not every nutrient reaches other organs to the same extent. This does not establish immediate feeding of the entire conifer.
Good to knowBrown old sections do not regrow simply because a foliar feed is applied.

Development influences requirements
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.
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.
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.
Application & calculator →Adapt care to the growing conditions and stage of growth. If you notice changes, check light, water and roots first — then take targeted action.
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.
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.
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.
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.
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.
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.
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.
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.
These details help distinguish normal foliage renewal, site problems and possible pests:
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.

Consider light, water, root space and nutrients together. More fertiliser cannot solve every care problem.
Read the guideAt 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.
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.
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.
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.
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.
