Rough guide for root feeding one leafy clematis, not foliar application. Height and width do not replace checking the root ball; use actual water volume for trellised plants.
How the guide is calculated
General GREEN24 guide: height (m) × width (m) × 3–4 litres. Centimetres are converted to metres. The concentrate amount follows this fertiliser’s standard dilution. The estimate does not measure individual water requirements.
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. When using the size-based guide, also check root space and actual root-ball moisture.
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 3–4 weeks during active growth; normally April–September. Account for nutrients already present, especially in fresh compost. Do not continue the summer schedule during dormancy.
Watering · through the roots
Pre-moisten the root zone and distribute the mixture through rooted soil. Let excess water drain from containers; first correct dry root balls or waterlogging.
Spraying · onto the leaves
Finely wet existing leaves in overcast conditions or morning or evening; avoid open flowers. Foliar feeding counts towards the same feeding plan and is not automatically added to root feeding.

Ask about specific mixability →Beyond NPK · understand the formulation
Well mixed – available to leaves and roots
The liquid NPK concentrate supplements nutrition during clematis growth. The diluted feed is intended for roots and existing foliage.
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 adherence help distribute the spray solution across the leaves. Dissolved nutrients are then available at the leaf surface for uptake.
Reduce hard-water effects
The formulation helps reduce adverse hard-water effects and deposits on the leaves. Low-lime water or rainwater provides a good starting point.
Feed with plant tolerance in mind
Application according to the label supports clematis in garden and container. Suitable root conditions, light and moisture remain separate requirements.
Understand foliage and flowering
Nutrients contribute to leaf development and metabolism. Flowering season and abundance also depend on species, cultivar, site and pruning; the fertiliser does not promise a particular flower number or size.
Chelation can reduce effects of hard water in solution; it does not remove calcium or magnesium. The product pH of 6.9 describes the concentrate, not the soil or a guaranteed pH of the diluted feed.
Use clean, suitable watering or spraying equipment. Measure the water and calculated concentrate quantity carefully.
Clematis through the year
Shoots. Flowers. Seed heads.
Clematis includes early and late flowering climbers as well as herbaceous forms. Seasons and flowers differ by species and cultivar; the scenes show examples.
Support growth and flowering.
Nutrition is one part of clematis care. Root conditions, light, water and the correct pruning group affect growth and flowering. Fertiliser does not replace a suitable position or pruning.
Leaves support the clematis
Leaves use light to make sugars. Many garden forms are deciduous, some species evergreen; foliage and seasons differ.
Flowering by species and pruning group
Early species bloom in spring on old wood; later types may flower on new growth. Images show group examples and do not imply continuous flowering of one cultivar.
Seed heads after flowering
Many clematis develop decorative silky seed heads. Flowering and seed production depend on species, cultivar and weather; they are not a food crop.
Choose clematis for its space and support
Climbing clematis grip slender supports with leaf stalks. Compact and herbaceous types need different space planning from vigorous climbers. Check cultivar and pruning group before purchase.
From root to flower
How clematis uses nutrients
Fine roots absorb water and dissolved nutrients. Leaves use light to make sugars for growth. Stems connect the plant and carry leaves and flowers. Nitrogen supports foliage, phosphorus energy transfer and potassium water balance. Flowering and dormancy differ by species, cultivar and pruning group.
Roots · uptake & anchorageFine root areas access water and dissolved nutrients.
Fine roots need moist, aerated soil. Container root space is limited; drainage holes and suitable compost without waterlogging matter.
Stems · transport and supportCarry leaves and flowers; leaf stalks of many climbers grip slender supports.
Climbing and herbaceous clematis grow differently. Living previous-year stems matter for the first bloom in pruning group 2; group 3 flowers on new growth. Identify the cultivar before pruning.
Leaves · turning light into sugarsLeaves use light to produce sugars for growth and flowering.
Many garden forms are deciduous, while some species are evergreen. Nutrients support leaf functions but do not replace light. Autumn leaf fall is normal for deciduous types.
Seed heads · decorative fruiting structuresMany clematis form silky seed heads after flowering; they are not a food crop.
Small dry fruits often carry elongated feathery styles, forming the fluffy overall look. Seeds of garden hybrids do not necessarily retain cultivar traits.
Understanding plant feeding
How nutrients enter your clematis
Root feeding brings diluted solution into clematis root space. Fine roots take up dissolved nutrients; foliar feeding puts solution on existing leaves. Both routes belong to one feeding plan.
Select a point in the picture or choose a stage.
Stage 01 / 04
Nutrient solution reaches fine roots
In pre-moistened soil, the diluted mixture meets fine root areas. Dissolved nutrients are available for uptake at the contact surface.
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
Uptake at the root surface
Fine root hairs increase contact with the soil. Transport proteins in cell membranes help take up dissolved nutrients.
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
Living root cells regulate uptake
Dissolved nutrients pass through regulated steps in living root cells. The clematis is not simply flushed with the entire contents of the feed solution.
Good to knowMore fertiliser does not automatically mean better nutrition.
A closer look
Controlled steps within root tissue lie between the root surface and onward transport. Transport across cell membranes enables nutrient uptake; water movement and nutrient uptake are different processes.
Stage 04 / 04
Onward to shoots and leaves
Water and absorbed nutrients can move through the xylem to above-ground parts. Healthy roots and active leaves are part of this process.
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.
Stage 01 / 04
The solution wets existing leaves
The diluted mixture contacts the leaf surface. Apply in the morning, evening or under overcast skies, avoid open flowers and observe the temperature limits.
Good to knowThis concentrate is also suitable for foliar application. Use only diluted and include it in the combined feeding plan.
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
Crossing the protective leaf surface
Dissolved nutrients can cross the protective surface layer; routes involving small leaf openings may also contribute. Conditions and leaf characteristics affect uptake.
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
Living leaf cells take up nutrients
After crossing the surface, living leaf cells can take up nutrients and use them in metabolism. A visible droplet alone does not demonstrate this step.
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
Use in the leaf and onward movement
Absorbed nutrients can be used in the leaf or redistributed, depending on the nutrient. This does not mean immediate uniform supply to every shoot or flower.
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.
Development influences requirements
Establishment, growth and winter dormancy
Young and newly planted clematis
First secure root-ball moisture, stability and protected stems. Fresh pre-fertilised compost counts towards nutrition. The label does not establish a separate stronger or weaker dilution for young plants.
Growth, foliage and flowering
Observe stems, foliage and flowers during growth. Spring and summer bloomers and old and new flowering wood differ; coordinate label feeding with moisture and nutrients already present.
Winter · species-dependent dormancy
Many garden forms shed leaves in autumn and rest in winter. Evergreens behave differently and may need protection. Do not extend summer feeding mechanically into dormancy.
Consider species, cultivar, season, roots and existing nutrients together. Height alone sets neither dilution nor water amount.
Application & calculator →Your growing conditions matter
Where does your clematis grow?
Climbing, compact and herbaceous forms need different space. Choose position, moisture, planting depth and support for the species and cultivar.
Container · moisture & drainage
Choose a stable container with drainage, enough root space and suitable support. Check root-ball moisture and let excess drain. Account for compost nutrients when applying liquid feed.
In ground · roots and support
Provide aerated, drained root space and a stable support with slender elements. Sun to partial shade with a cool root zone suits most garden forms. Choose planting depth by plant group.
Hardiness by species and cultivar
Container roots face more frost than roots in the ground. Tender evergreen species need suitable shelter; deciduous types shed their leaves.
Trellises and herbaceous types
Climbers grip slender supports with leaf stalks. Guide non-climbing herbaceous types loosely or support them among neighbouring plants. Plan pruning by cultivar and group.

Understand plant care problems
What has changed on your clematis?
Wilting stems, yellow leaves or few flowers have different causes. Check root-ball moisture, drainage, stem injury, position and pruning group before changing feeding.
Investigate sudden wilt
Fungal clematis wilt especially affects large-flowered hybrids. A dry root ball or damaged stems can look similar. Inspect roots and stem bases, remove affected dead stems and seek advice when the cause is unclear.
White coating on leaves
A powdery coating can indicate powdery mildew. Inspect both leaf surfaces, improve airflow and reduce drought stress; choose treatment only after suitable diagnosis.
Inspect young shoots and leaves
Aphids can colonise soft tips, while slugs and snails especially damage young shoots. Inspect regularly, identify the pest and damage, and choose targeted measures instead of a routine spraying programme.
Protect roots and stems
Dry roots, waterlogging or a broken stem can cause similar visible symptoms. Check root-ball moisture, clear drainage holes and stem injuries before adding fertiliser.
Advice for clematis
These details help assess growth and possible damage:
- Photos of the whole plant, stem base, young shoots and both leaf surfaces; include flowers and affected roots.
- Species or cultivar and pruning group if known; container or ground, support, planting depth and compost used.
- Record when the change began, root-ball moisture, pruning, weather and previous feeding.
One symptom does not prove a nutrient deficiency. Sudden wilt may also involve dry roots, stem injury or disease; large-flowered hybrids can be affected by fungal clematis wilt.
Pests or disease: plant protection
Check root-ball moisture, roots, damaged stems and leaf undersides. For advice, provide photographs of the whole plant and affected parts, together with the cultivar name.
