Use a clean watering can or sprayer; preferably low-lime water or rainwater at 15–25 °C.
Calculate the amount
Enter the water volume and read the calculated concentrate amount.
Add some water first
Start by filling the container with part of the chosen water volume.
Shake & measure
Shake well. Measure the calculated amount using a suitable measuring aid.
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 2–3 weeks during growth. Do not add feed during dormancy.
Watering · through the roots
Moisten the root ball first, then distribute the mixture across the root zone. Let excess water drain through the pot; do not leave nutrient solution standing in a cachepot.
Spraying · onto the leaves
Wet the foliage lightly in the morning, evening or under overcast conditions, avoiding open inflorescences. Root and foliar feeding belong to one programme, not two parallel routines.

For Alocasia
For Alocasia · elephant's ear; follow this concentrate's directions.
During growth
The plant is actively growing; moisten the root ball before application.
Consider the root zone
Account for nutrients in fresh compost. Check the cause of care problems first.
Beyond NPK · understand the formulation
Well mixed – available to leaves and roots
Declared main and trace nutrients are applied in diluted form. Refer to the full nutrient declaration for proportions.
Protected trace nutrients
The declaration lists copper, iron, manganese and zinc as EDTA chelates. Individual proportions are listed below.
Fewer hard-water effects
Preferably use low-lime water or rainwater at 15–25 °C. Product pH describes the concentrate, not the prepared solution or compost.
For sensitive foliage plants
Dilute according to the label and apply during growth. Check root damage and unsuitable growing conditions first.
Understanding leaf quality
Appropriate nutrition supports leaf formation and greenness. Leaf finish means an even, well-cared-for appearance, not a sprayed-on gloss coating. Species, light and maturity also shape natural leaf patterns and form.
Follow this product's water quality and application directions. These do not establish a general water-treatment programme.
Suitable for compatible fertiliser dosing equipment. Set equipment to this product’s dilution and follow the device instructions.

Alocasia · elephant's ear: understanding leaves and roots
Light, water, root space and nutrients work together. These scenes show the plant and its care; they do not demonstrate a fertiliser effect.
Preserve the root ball
The ball and fine roots form one unit. Support it from below and remove only loose old compost.
Fine roots and rhizome
Fine roots absorb water and nutrients. The rhizome stores reserves; handle both gently when repotting.
Position the crown correctly
Keep the leaf-stalk base at its original level. Do not heap extra compost over the crown and rhizome.

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.
What does a plant do with nutrients?
Roots · absorb & anchorExplore the limited root space inside the pot.
Fine roots need contact with moist compost as well as oxygen. An open structure and drainage help provide both. Feed the pre-moistened root ball with diluted solution, never with concentrate applied directly to roots.
Leaves · capture energyGreen leaf tissue makes sugars for the whole plant.
The green areas of the broad leaves use light for photosynthesis. Nitrogen is needed for chlorophyll and proteins, among other things. White sectors of variegated plants do not perform like green tissue; extra fertiliser cannot replace light or green leaf area.
Leaf stalks · connection & supportConnect leaf blades with the plant base.
Vascular tissues connect roots and leaves. Xylem carries water and mineral nutrients; phloem carries substances including sugars. Avoid damaging shoots and leaf stalks.
Rhizome · reserves & new growthStorage organ supporting roots and new growth.
The rhizome stores reserves. Handle gently when repotting and do not bury the crown deeper. Dormancy is no reason for concentrated fertiliser.
New leaf · unfurl & matureInitially receives support from established leaves.
A new leaf unfurls and matures. Do not force it open. Development and leaf size also depend on species, light and growing conditions.
How nutrients enter Alocasia · elephant's ear
Select a point in the picture or choose a stage.
Stage 01 / 04
Water carries nutrients to the roots
The mixture reaches the compost around the fine roots. Dissolved nutrients are available at the interface between roots and growing media.
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
Roots take up dissolved nutrients
Fine root hairs increase contact with the growing medium. Tiny transport proteins in the membranes surrounding root cells help dissolved nutrients enter the cells.
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
An inner layer controls the route
On their way into the root, nutrients meet a special layer of cells. It prevents substances from simply flowing through the gaps between cells and helps the plant control uptake.
Good to knowMore fertiliser does not automatically mean better nutrition.
A closer look
Nutrients move through the root tissues. The endodermis acts as a control layer: its barrier interrupts unrestricted movement along the cell walls.
Stage 04 / 04
Transport channels carry water and nutrients
Inside the root are fine transport channels called xylem. Water and absorbed nutrients can travel through them towards shoots and leaves.
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
Diluted solution is applied to the leaf
The prepared solution wets the leaf surface. Avoid open flowers and always dilute correctly.
Good to knowThis product is labelled for foliar application. Always dilute correctly.
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
Nutrients must cross the protective surface
The leaf surface protects the plant. Dissolved nutrients can pass through this layer; tiny openings in the leaf may also play a part. Uptake varies with the type of leaf and the conditions.
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
Cells inside the leaf take up nutrients
Behind the surface lies living leaf tissue. Its cells can take up nutrients that have crossed the surface and use them for their activities.
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
Nutrients are used in the leaf and may move onward
The plant can use absorbed nutrients within the leaf. Some can also reach other plant parts. This depends on the nutrient and the plant's condition.
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
Care that follows each flush of growth
Young plant & establishment
For young plants, consider root establishment, light and nutrients already in compost. Unrooted cuttings are not established pot plants.
New leaves & shoots
When leaves unfold and shoots develop, feeding can be part of the care routine. Keep the feeding interval separate from watering: not every necessary watering needs fertiliser.
Lower light · slower growth
As growth slows, check compost moisture and adjust care to demand. Do not try to force dormant plants into growth with extra fertiliser.
Actual development matters: species, location and season affect the pace. Plant size alone determines neither dose level nor watering volume.
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.
Caring for Alocasia · elephant's ear
Indoors · enough light to grow
A bright position without harsh midday sun supports leaf development. Gently remove dust from broad leaves. Extra fertiliser cannot compensate for growth slowed by persistently poor light.
Humidity and temperature
Protect from cold draughts. Consider the species' light and humidity needs.
Recognise dormancy
Water dormant plants less. Leaf loss does not automatically mean nutrient deficiency; check light, moisture and roots first.
Pots & repotting · consider the roots
A draining pot and open, stable compost help manage moisture. After repotting, account for nutrients already in the new compost. This guide does not establish a programme for hydroponics or a permanent nutrient reservoir.

Plant health advice for Alocasia · elephant's ear
These details help distinguish growing conditions, root or nutrition problems and an infestation:
- Photos of the whole plant, both leaf surfaces, leaf stalks and affected stem nodes.
- Species or cultivar, pot size, compost and position near a window; root photos where relevant.
- When symptoms began and progressed, pot moisture, repotting date and previous fertiliser or plant protection applications.
Check the cause, crop and authorised growing location first. A product recommendation does not approve mixing.

Quick answers before you buy (FAQ)
How much solution do the packs make?
At 5 ml per 2 l of water, 250 ml makes 100 litres of prepared solution and the twin pack makes 200 litres. Both contain the same formulation.
When and how often should I feed?
Every 2–3 weeks during the growing period. Observe actual growth; do not try to force a dormant Alocasia with extra feed.
Can I use it on the leaves?
The product is labelled for watering or spraying. Always dilute 5 ml in 2 l of water, avoid open flowers and do not apply in direct sun, below 5 °C or above 30 °C. Both routes belong to the same feeding programme.
Does leaf loss always mean nutrient deficiency?
No. Alocasias may lose foliage during dormancy. Check light, temperature, compost moisture and roots first; extra fertiliser is not an automatic solution.
Should I feed straight after repotting?
Account for nutrients in fresh compost. With the linked Alocasia Compost, review nutrition after four to six weeks and supplement only if needed. Handle the rhizome gently when repotting.
Are complementary products approved for mixing?
No. “Pairs well with” identifies complementary care products. Mix products only when both sets of directions allow that exact combination.
