Care that suits your palm
Know your palm species
For tropical and subtropical palms. Choose indoors, conservatory or container growing according to species; palm-like plants are not automatically true palms.
Feed according to growth
April–September is the regular period; tropical species follow their actual growing phase. Pause feeding during a growth pause.
Include the growing medium
After repotting, account for existing fertiliser and handle the root ball gently. Check moisture and drainage before feeding.
Application in one place
Measure. Mix. Apply.
Palm dilution calculator
Choose the water volume or use your palm’s height and width as a rough watering guide. The calculator uses the confirmed standard dilution; young plants and seedlings have their own settings.
Base dilution: 5 ml per 1.5–2.5 l of water. The calculator uses the confirmed standard dilution of 5 ml per 1.5 l. For young plants or seedlings, the selected setting reduces the concentrate amount.

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 guide for watering the roots of one palm, not for spraying or hydroponics. Measure height from the growing-medium surface and the width of the crown, not just stem length. Root-ball moisture, pot volume, rooting, light and temperature also matter. Use only when watering is needed; do not cause standing water or force the whole guide volume into the pot.
How the guide is calculated
General GREEN24 guide: height (m) × width (m) × 3–4 litres. Centimetres are converted to metres. Concentrate quantity follows this fertiliser’s confirmed standard rate and the selected setting. The guide does not measure the individual water needs of your palm species.
Prepare a clean container
Use a clean watering can or sprayer; preferably low-lime water or rainwater at 15–25 °C.
Calculate the amount
Choose the water volume and dilution setting. The standard dilution and original range are shown beside the calculator; plant size does not select the setting automatically.
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? Feed during growth; repeat according to your palm’s development, without a fixed weekly interval. The regular period is April–September; tropical species follow their growth periods. Account for pre-fertilisation and earlier feeds.
Watering · through the roots
Moisten the root ball first and distribute the fully diluted mixture evenly over the growing medium. Allow excess water to drain. Check below the surface; water collects around roots in an undrained outer pot.
Spraying · suited to the fronds
If the species, leaf surface and growing conditions suit foliar feeding, lightly wet the fronds in the morning, evening or overcast conditions. Avoid open flowers. Root and foliar feeds belong to the same nutrient supply.

Request the compatibility table →Beyond NPK · understand the formulation
Well mixed – available to roots and fronds
Water-soluble nutrients and the formulation support straightforward feeding for your palm. Discover the properties of the finished watering or spraying solution.
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
At a suitable dilution, high plant tolerance supports the development of new fronds. Appropriate nutrition supports your palm’s natural foliage.
Understand frond quality and growth
Suitable nutrition supports leaf development and green foliage. Leaf finish means an even, well-kept appearance, not a sprayed-on gloss film. The rate of new frond development also depends on species, light, warmth and roots. Feed during actual growth.
Chelation binds metal ions and can reduce adverse hard-water effects; it does not remove calcium or magnesium from the water. The product pH of 6.8 describes the concentrate. The finished mixture’s pH also depends on the source water; no fixed target value is promised.
Use clean, suitable watering or spraying equipment. Measure the water and calculated concentrate quantity carefully.
Green fronds. A special place.
When a new frond unfolds
A narrow spear at the centre of the crown gradually opens into a new frond. Fans or fine leaflets bring light and shade to life, revealing the development of your palm.
Support the next growing period with care.
A suitable nutrient supply belongs in your palm-care routine alongside light and a healthy root zone. A measured water volume and the calculator make the concentrate easy to include in your care.
Fans and leaflets shape the space
Each palm species has its own habit: broad fans, slender leaflets or gracefully arching fronds. Suitable light and space allow that natural form to stand out.
The new spear becomes a frond
New fronds develop at the growing point of each stem. Watch the central spear open and retain living fronds on the plant.
Good care starts in the root ball
In a pot, water, air and root space must work together. Check moisture below the surface and allow excess water to drain.
The right palm for your space
A kentia in a bright room needs different care from a windmill palm in a garden. Choose position and winter care by species; the plant profile helps you compare them.
From root ball to growing point
How does your palm use nutrients?
Fronds use light to make sugars. Roots supply water and mineral nutrients. Transport tissues in the stem link these areas with the growing point, where new fronds develop. Nutrition and growth work together.
Roots · absorb & anchorAnchor the palm and explore the moist root zone.
Roots need water as well as air in the growing medium. A well-rooted, freely draining root ball provides both. Handle roots gently when repotting, retain the previous planting depth and account for fertiliser in the new compost.
Fronds · capture light & energyFans and leaflets make sugars for the palm.
Green fronds provide the basis for further growth through photosynthesis. Nitrogen contributes to chlorophyll and protein formation. More fertiliser alone will not correct slow growth in a dark position. Retain living fronds.
Growing point & stem · connect growthNew fronds develop from the growing point of each stem.
The central spear is the new leaf. Do not shorten the stem or cut off its growing point: that stem will not replace it with ordinary side shoots. Clumping species have several stems; several seedlings in one pot are not branches of one plant.
Nutrients · working togetherNitrogen, phosphorus and potassium for mineral nutrition.
Nitrogen supports chlorophyll and proteins in green fronds. Phosphorus contributes to energy transfer; potassium supports water regulation and transport. Declared trace nutrients complement the supply. No magnesium content is declared for this fertiliser; investigate unusual fronds rather than assuming a deficiency this product will cure.
Understanding plant feeding
How nutrients enter your palm
From the root ball or frond surface into living tissues: explore the uptake routes. Choose the application to suit your palm species and its growing conditions.
Select a point in the picture or choose a stage.
Stage 01 / 04
Nutrient solution reaches the palm roots
The mixture reaches the growing medium around the palm’s roots. Dissolved nutrients are available at the interface between moist medium and absorbing root surfaces.
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 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
Root cells regulate uptake
In your palm's roots, cell membranes and their transport proteins regulate the uptake of dissolved nutrients. Substances do not simply flow unfiltered into the plant with the irrigation water.
Good to knowMore fertiliser does not automatically mean better nutrition.
A closer look
Between contact with the root surface and onward transport, controlled processes take place within the root tissues. Transport across cell membranes helps the palm take up nutrients; water movement and nutrient uptake are distinct processes.
Stage 04 / 04
Onward through the stem to the fronds
Inside the roots are transport tissues called xylem. Water and absorbed nutrients can travel through the stem to the fronds and other growing areas.
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 wets the palm frond
The fully diluted mixture wets the frond surface. Account for palm species and growing conditions, avoid open flowers and spray only within the application limits.
Good to knowOur Palm Fertiliser also allows suitable foliar application. The choice depends on species, leaf surface and growing conditions; the feed belongs to the same nutrient 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
Uptake across the frond 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
Living frond cells 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
Use within the leaf and possible redistribution
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
Keep the next frond in view
Seedling & young palm
Young palms need a suitable, consistently supplied root zone. The calculator gives young plants half the standard dilution and seedlings one fifth. Account for nutrients in seed or potting compost. Repotting does not automatically make an older palm a young plant.
New fronds & active growth
When new fronds develop, plan light, moisture and nutrients together. Repeat feeds according to growth, not a rigid weekly schedule. Size and warmth alone determine neither the dose nor the next feed.
Growth pause & overwintering
Pause feeding during a growth pause. Tropical indoor palms can grow for longer under suitable conditions; container palms need winter quarters matched to their species. Assess light, warmth and actual growth together.
Developmental stage remains a separate decision. Height or pot size determines neither the growth stage nor a higher concentration.
Application & calculator →Your growing conditions matter
Where does your palm grow?
True palms share their basic structure, not one set of growing conditions. Species determines whether a bright room, conservatory, patio or sheltered garden position is suitable.
Indoors · check light at the plant
Parlour, kentia and golden cane palms are common indoor choices. Provide suitable bright light and avoid dry heated air. Check root-ball moisture and water in the outer pot; a bright room is not equally bright everywhere.
Conservatory · balance warmth and light
Light and temperature can vary considerably under glass. Allow space for the mature crown and acclimatise gradually to stronger sun after moving the plant. Warmth alone is not a reason for an extra feed.
Containers · provide drainage and winter quarters
Sunny outdoor positions can suit Phoenix or Chamaerops where other conditions are appropriate. Monitor moisture and drainage in the limited root space. Prepare species-appropriate winter quarters or protection before cold weather.
Garden · choose a suitable species and site
Windmill palms may suit sheltered garden positions. Assess climate, age, root conditions and protection of roots and growing point together. This does not establish one cold limit for all palms or frost protection from fertiliser.

Understand plant care problems
What is changing on your palm?
Brown tips, yellow fronds or an unusual central spear deserve a closer look. Compare old and new fronds, root-ball moisture, light and possible pests before changing your care.
Scale insects and mealybugs
Inspect leaf undersides, leaflet bases and stalks. Attached scales, cottony deposits or sticky honeydew help identify the problem.
Spider mites
Check indoor palms for fine pale stippling and webbing. Examine undersides with a magnifier and move affected plants away from neighbours.
Root or bud rot
Persistently wet compost, soft tissues or a rotting spear need investigation. Check drainage and roots; extra fertiliser will not cure rot.
Brown tips and yellow fronds
First compare root-ball moisture, salt build-up, light and dry heated air. Individual old outer fronds age naturally; damage to several young leaves is a different sign.
Sun and cold damage
Acclimatise gradually to stronger sunlight after moving a plant. Never apply one species' cold tolerance to all palms; pay particular attention to the container and growing point.
Advice for your palm species
These details help assess problems with growing conditions, roots and foliage:
- Photographs of the whole palm, the central spear and both sides of affected fronds.
- Botanical name, indoor or outdoor position, pot size, growing medium and when the palm was last repotted.
- When the changes began, root-ball moisture and drainage, changes in light or temperature, and previous feeding or treatment.
Palm species and the cause determine the next steps. Yellow fronds alone do not establish a nutrient deficiency; extra fertiliser will not restore a soft, rotting spear.

Quick answers before you buy (FAQ)
Is this fertiliser suitable for my plant?
For tropical and subtropical palms. Choose indoors, conservatory or container growing according to species; palm-like plants are not automatically true palms.
How do I dilute the concentrate?
Dilution: 5 ml per 1.5–2.5 l of water.
Measure out the concentrate and mix it with the stated amount of water. Never apply undiluted.
How much solution does one pack make?
At standard dilution, 250 ml is sufficient for 75 l of water, 2 × 250 ml for 150 l and 1 litre for 300 l. Across the full dilution range, these become 75–125, 150–250 and 300–500 l of water for preparing the solution.
What should I check before use?
Do not apply in sunlight, below 5 °C or above 30 °C. Never apply the concentrate undiluted.
