For cucumbers and courgettes

Both belong to the cucurbit family, but they are trained differently. Warmth, consistent moisture and enough space matter alongside nutrition. The fertiliser is labelled for cucumbers and courgettes; missing fruits or yellow leaves do not automatically mean nutrient deficiency.

During active growth

5 ml per 1.5 l of water · every 1–2 weeks during active growth. Shake well before use and never apply undiluted. One capful equals 5 ml according to the label. Start young plants on half the dose. Official advisory recommendations take precedence. Feed the pre-moistened root zone or spray both leaf surfaces evenly; avoid open flowers. Preferably use low-lime water or rainwater at 15–25°C. Do not feed in direct sunlight, below 5°C or above 30°C.

Account for existing 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.

Understand this formulation

Add nutrients at the right dilution

NPK 4.3 + 5.7 + 8.5 Product pH: 6.9. This describes the concentrate, not the soil or diluted watering solution. 4.3% total nitrogen (N), including 3.6% urea nitrogen. 5.7% water-soluble phosphate (P₂O₅). 8.5% water-soluble potassium oxide (K₂O). Boron (B): 0.0075%. 0.003% water-soluble copper (Cu), as EDTA chelate. Iron (Fe): 0.0150%, as EDTA chelate. Manganese (Mn): 0.0090%, as EDTA chelate.

Water-soluble declaration

The composition lists nutrients declared as water-soluble on this product's own label. Mix the measured concentrate thoroughly in water.

Declared trace nutrients

See this product's declaration for amounts and any chelate bindings. This does not justify an additional unmeasured trace-nutrient feed.

Account for water and position

Follow this product's water and application directions. Concentrate pH does not establish a guaranteed pH for soil or diluted solution.

Measure accurately and store correctly

Retain the original container and labelling and follow this product's full directions.

Nutrients in context

Nutrition, light, water and root condition work together. Extra fertiliser cannot correct insufficient light or damaged roots.

Moisten the root zone first. Then distribute the solution diluted to the label rate evenly, allowing excess water to drain.

Use clean suitable containers and an appropriate measuring aid.

Products

The recommendations cover products for different care tasks. Combining them in the same solution requires the instructions for both products to allow that combination. Otherwise, apply the products separately.

Do not mix undiluted concentrates together. Follow the confirmed mixing conditions and application routes of each product.

Climbing cucumber and bush courgette

Cucumbers can climb supports while many courgettes form a broad bush. Pollination requirements and fruit set depend on the cultivar.

Foliage and habit

Large herbaceous leaves. Shape, hairs and natural pale markings vary with crop and cultivar.

Flowers and development

Cucumbers can climb supports while many courgettes form a broad bush. Pollination requirements and fruit set depend on the cultivar.

Fruit development

Cucumbers, courgettes and pumpkins form fleshy fruits but are harvested at different stages. Culinary squashes must be distinguished from ornamental gourds.

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

Cucumbers can climb supports while many courgettes form a broad bush. Pollination requirements and fruit set depend on the cultivar.
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.

Cucumbers can climb supports while many courgettes form a broad bush. Pollination requirements and fruit set depend on the cultivar.

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.

Young plants and establishment

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.

Active growth

5 ml per 1.5 l of water · every 1–2 weeks during active growth. Shake well before use and never apply undiluted. One capful equals 5 ml according to the label. Start young plants on half the dose.

Rest period

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.

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.

Seit ich diesen Dünger benutze ist meine Gurken Pflanze ertragreicher als sonst. Die Blätter sind riesig und Gurken kann ich fast täglich ernten. Das Wetter ist zwar auch ideal aber da ich jedes Jahr Gurken habe merke ich den Unterschied - mit und ohne Dünger. Auf alle Fälle eine Empfehlung.

Habe bis jetzt 2 mal meine Zucchinis damit gedüngt, sie wachsen und sind viel weiter als die meiner Gartennachbarn.

Ich hab diesen Dünger für meine Zucchinis genutzt. Sie sitzen in Töpfen und das Ergebnis war der Wahnsinn. Mittlerweile hab ich 14 riesige Zucchinis geerntet und 6 Stück kommen noch. Vom Geschmack her waren sie auch ganz wunderbar. Den Dünger kann ich nur empfehlen.

Habe dieses Jahr das 1. Mal damit begonnen, die Gurken zu düngen. Ich muss sagen, sie tragen schon viel früher und mehr Blüten und kleine Früchte. Dünge nach Anweisung, 1x wöchentlich Blätter und Wurzelballen. Kaufe ich wieder.
