A rough guide for root watering of one leafy plant, not for spraying. Measure height from soil level and full plant width, not fruit length or a single leaf. Also check the pot, moisture, substrate and weather; a known water quantity remains the direct input.
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
Select the water quantity in the calculator. Initially select the half rate for young chillies and peppers.
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? 5 ml per 2.5 l of water. With every watering until the fruit is ripe, during the growing season. Regular application period: March–September. Initially feed young plants at half strength.
Watering · through the roots
Distribute the mixture in the previously moistened root zone. In pots, consider the whole root ball and free drainage. Extra concentrate does not improve feeding in a small, dry root ball.
Spraying · onto the leaves
Moisten both leaf surfaces finely in the morning, evening or under overcast skies; avoid open flowers. Foliar feeding belongs to the same feeding plan as root application, not automatically on top of it.

Does it suit your plant?
For chillies and sweet peppers
For chillies and sweet peppers of the genus Capsicum under suitable cultivation. Species and cultivar determine growth habit, fruit ripeness and further care.
During active growth
Usual period March–September. Apply with each watering until fruit ripeness during the growing season.
Initial nutrients count
After planting or repotting, account for pre-fertilisation in the compost. If roots are dry or damaged, address growing conditions first.
Beyond NPK · understand the formulation
The nutrient solution for roots and leaves
The water-soluble nutrients are diluted with water. For chillies and peppers, this product supports application through the root zone and onto existing 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 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
When used correctly, the plant-compatible formulation supports feeding chillies and peppers. Young plants initially receive the specified half rate. Light, warmth and a functioning root zone remain necessary.
Understand leaf formation and fruit development
Nutrients support leaf formation and metabolism. Leaf finish means the appearance of well-kept foliage, not a glossy coating. Fruit count, colouring and heat cannot be predicted from this; species, cultivar and growing conditions also contribute.
Chelation can reduce disruptive hard-water effects; calcium and magnesium are not removed from the water. The product pH of 6.9 describes the concentrate, not the soil. Source water influences the final mixture’s pH; no fixed target is promised.
Use clean, suitable watering or spraying equipment. Measure the water and calculated concentrate quantity carefully.

GREEN24 · Plant knowledge
Branching shoots. Small flowers. Different fruits.
Flowers and later fruit develop among the simple leaves. Elongated chillies and blocky sweet peppers represent only part of Capsicum diversity. Fruit shape, colour and heat depend on species and cultivar.
Leaves produce sugars
The simple, usually entire leaves use light for photosynthesis. Leaf surfaces and hairiness differ between Capsicum species. Intact leaves supply the plant with sugars they produce.
Small flowers along the branches
Many Capsicum flowers are whitish; other species can have violet colouring. Self-pollination is possible, while insects can transfer pollen between plants. Avoid open flowers when spraying.
Assess fruit shape and ripeness by cultivar
Sweet peppers and hot chillies belong to the same genus. The stage used in cooking and full ripeness may differ.

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 chillies and peppers use nutrients
Roots · uptake & anchorageFine root regions absorb water and dissolved nutrients.
Chillies and peppers need an aerated root zone with even moisture but no waterlogging. Fine roots access the solution within the substrate. In containers, root-ball size and drainage also constrain supply.
Leaves · turning light into sugarsSimple leaf surfaces use light to produce sugars for the plant.
Leaves supply growing shoots and fruit with sugars they produce. Shape, surface and hairiness vary between Capsicum species. A stronger nutrient solution cannot compensate for insufficient light.
Shoots · branch and connectBranching shoots carry leaves, flowers and individual fruit.
Vascular tissues connect the root zone to the above-ground plant. Capsicum forms branching shoots that may become woody at the base. Loosely support heavily laden branches; one pruning rule is not suitable for the different species and cultivars.
Fruit · growth and ripeningFruit uses water, sugars and nutrients for development.
Flowers can self-pollinate; insects can transfer pollen between plants. The stage used in cooking and full ripeness differ by cultivar.
How nutrients enter chillies and peppers
Select a point in the picture or choose a stage.
Stage 01 / 04
Nutrient solution reaches the 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
Root cells regulate individual uptake steps. The plant is not simply flushed through with the entire contents of the watering 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
Onwards 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 the leaf
Distribute the diluted mixture finely over both leaf surfaces. Apply in the morning, evening or under overcast skies and avoid open flowers.
Good to knowThis Chilli & Pepper Fertiliser is also suitable for foliar application. Use only when diluted and include the application in the overall 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
Leaf cells absorb 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
Nutrients may be used in the leaf or redistributed depending on the nutrient. This does not imply immediate, uniform nutrition of all fruit.
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
Young plants, growth and slowing vegetation
Young plants · half strength initially
Feed young plants at the specified half strength initially. Account for initial nutrients, root contact and moisture. No universal age or fixed height defines this initial phase.
Leaves, flowers and fruit develop
During the growing season, further branches, leaves and fruit develop. Coordinate the specified feeding plan with actual water demand and existing nutrient supply.
Reassess when growth slows
Development can slow as light decreases and temperatures fall. Feed only during the growing season; the usual period is March–September. Frost-free overwintering of selected Capsicum plants is a separate cultivation task, not a reason to continue unchanged feeding all year.
Consider growth, roots, warmth and existing nutrients together. Plant height alone determines neither feeding strength nor water needs.
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.
Where do your chillies and peppers grow?
Containers · root ball and drainage
Use a suitable container with drainage holes. Regularly check moisture in the limited root ball and account for pre-fertilisation. Support heavily laden branches if needed and avoid crowding the plant between other containers.
Beds · warm and sheltered
Plant in a suitable warm position only after the last frosts. Gradually acclimatise young plants to outdoor conditions and sunlight beforehand. Check soil moisture and existing nutrients; more root space in the ground does not imply the same watering need as in a pot.
Greenhouses · warmth without overheating
Provide light, air exchange and even moisture. Regularly check temperature and leaf undersides. If fruit does not set, inspect flower development and growing conditions, not just feeding.
Overwintering · frost-free and adapted
Selected healthy Capsicum plants can be kept frost-free. Light, temperature and actual growth then determine care. Winter quarters are not a reason to continue the summer feeding plan unchanged.
What is changing on your chilli or pepper plant?
Aphids, whitefly and spider mites
Inspect growing tips and leaf undersides. Record sticky deposits, pale feeding marks or webs and identify the cause before selecting treatment.
Spots, grey mould and wilting
Persistently wet foliage, dead plant material and still damp air can encourage problems. If plants wilt despite wet compost, inspect roots and drainage.
Blossom-end rot
Dark sunken areas at the blossom end of fruit may be a physiological disorder. Check steady water supply and root function; do not automatically increase fertiliser strength.
Flowers drop or fruit stays small
Consider warmth, excessive heat, light, water and pollination conditions together. A single symptom does not prove a particular nutrient deficiency.
Advice for chillies and peppers
This information helps us assess leaf development, growth habit and fruit set more precisely:
- Photographs of the whole plant, both leaf surfaces, shoot tips, flowers and affected fruit. Also show unusual roots or a wet root ball.
- Identify chilli or sweet pepper, ideally the species and cultivar, seed-grown or purchased young plant, pot size, substrate and whether it grows in a bed, on a balcony or in a greenhouse.
- Describe when the change began, light and temperature conditions, watering and previous feeding. If fruit is absent, also describe flower development and possible heat stress.
Leaf changes alone do not establish a particular nutrient deficiency. Use fruit only from varieties explicitly grown for food; ornamental plants are not automatically suitable for consumption. Keep hot fruit away from eyes and mucous membranes.

Quick answers before you buy (FAQ)
Which pack size suits my needs?
At the label rate, 250 ml makes 125 litres of fertiliser solution, the twin pack makes 250 litres and the 1 litre bottle makes 500 litres. Formula and dilution match on the two labelled bottle sizes.
How should I feed young chilli plants?
The label specifies half strength initially for young plants. Select the young-plant stage in the calculator. For 3 litres of water, this is 3 ml rather than 6 ml. Allow for nutrients already present in propagation or planting compost.
Will extra fertiliser make a chilli hotter?
Extra feed cannot guarantee a particular heat level. Variety and growing conditions influence the result. Do not exceed the label rate to force greater heat or yield.
Should I feed leaves and roots at the same time?
Watering and spraying are two routes for the same nutrient supply. Choose the appropriate application; foliar feeding is not an automatic extra portion. Both follow the product label, including temperature limits and avoiding open flowers.
When should I feed after repotting?
Check the initial nutrients and instructions for the new compost. The linked chilli and pepper compost specifies about six weeks before supplementary feeding. Account for growth, season and other nutrients supplied.
