Measure the calculated concentrate with a suitable measuring aid. Do not estimate small amounts by eye.
Enter a water amount from 0.1 to 1,000 litres.
Use the water volume actually needed. Plant height alone does not provide a reliable watering volume.
How the guide is calculated
Concentrate (ml) = water (l) × 5 ÷ 1.
Prepare a clean container
Use a suitable clean watering can or sprayer and follow this product's water directions.
Choose the water volume
Choose the amount actually needed. Check root-ball moisture and drainage before watering.
Add water first
Start with part of the selected water volume.
Shake and measure
Shake the bottle well. Measure the concentrate calculated for the selected water volume accurately.
Add the concentrate
Add the measured amount to the water; never apply concentrate directly to the plant.
Top up and mix
Top up to the chosen water volume and mix thoroughly. Water or spray according to this product's own directions.
When to feed? 5 ml per 1 litre of water 5 ml per 1 litre of water During fruit development. The growth-stage setting does not change the application timing. Every 1–2 weeks; May–September. Do not use undiluted. Shake well before use. Keep out of reach of children and animals. Preferably use low-lime water or rainwater at 15–25 °C.

Nutrients in context
Nutrition, light, water and root condition work together. Extra fertiliser cannot correct insufficient light or damaged roots.
Apply the prepared solution to a moist root zone. Match the water volume to the root ball and conditions; allow excess water to drain.
Use clean suitable containers and an appropriate measuring aid.

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.
Roots, foliage and growth
RootsFine roots contact soil water. Their cell membranes regulate uptake of dissolved nutrients.
Check compost and soil regularly, especially in containers. Water the root zone as needed and avoid waterlogging; weather and plant size determine the amount.
LeavesLarge herbaceous leaves. Shape, hairs and natural pale markings vary with crop and cultivar.
Many pumpkins need room for long vines. Use this concentrate during fruit formation as stated in its own profile; dose stages do not change the application period.
Shoots and habitCucumbers climb or trail; courgettes are usually bushy; edible pumpkins may form long runners, depending on cultivar.
Climbing cucumbers gain height using tendrils; bush courgettes carry leaves and fruit around a short main stem. Pumpkin runners may extend well beyond the planting site. A single pruning rule would overlook these differences.
Fruits and seedsCucumbers, courgettes and pumpkins form fleshy fruits but are harvested at different stages. Culinary squashes must be distinguished from ornamental gourds.
Pick cucumbers and courgettes young and regularly; let storage squashes mature. Do not eat bitter-tasting fruits: cooking does not make them safe. Use clearly identified culinary cultivars.

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.
Growing conditions
In containers
Check compost and soil regularly, especially in containers. Water the root zone as needed and avoid waterlogging; weather and plant size determine the amount.
In the garden
Begin with warmth, a sunny sheltered site and well-drained, adequately nourished root space. Distinguish greenhouse and outdoor cucumbers. Courgettes need room for their leaf canopy; large pumpkins often need still more ground. Containers must retain moisture while draining excess water.
Winter and rest
Harvest cucumbers and courgettes regularly. Bring storage pumpkins in when mature for their cultivar and before frost. Remove dead plants and sow again the following year.
Planting and repotting
Acclimatise young plants to outdoor conditions. Plant with roots undisturbed once the soil is warm enough; prepare support, spacing and drainage first. Do not treat pre-fertilised compost as a low-nutrient seed medium.
Observe and identify the cause
Aphids, whitefly and mites
Inspect young shoots and leaf undersides. Describe and photograph sticky deposits, pale speckling or webbing when seeking advice.
Mildew and leaf spots
Have white coatings distinguished from other leaf spots. Natural pale markings on courgette leaves are not by themselves evidence of disease.
Poor fruit set
Consider cold, heat, pollination, cultivar and moisture together. Parthenocarpic cucumbers set fruit without pollination; courgettes usually require it.
Discuss the care problem
These details help assess the problem:
- Record plant species, position and recent changes.
- Describe root-ball moisture, drainage and previous feeds.
- Provide an overview and clear photos of affected organs.
This guidance supports investigation; it does not replace a reliable diagnosis or authorised plant-protection directions.
