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) × 10 ÷ 2.5.
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? 10 ml per 2.5 l of water 10 ml per 2.5 l of water. Every 1–2 weeks during the growing season. Regular application period: April–August. Do not use undiluted. Shake well before use. Preferably use low-lime water or rainwater at 15–25 °C. Do not apply in direct sunlight or at temperatures below 5 °C or above 30 °C. Apply to a pre-moistened root zone or spray the foliage. Do not spray open flowers.
Watering · through the roots
Apply the diluted solution to the pre-moistened root zone. Allow excess water to drain from containers and account for nutrients in the soil or compost.
Spraying · onto the leaves
Wet leaves evenly according to the label, avoiding open flowers. Foliar feeding is part of nutrition, not an automatic extra dose.

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.
Apply the diluted solution to the pre-moistened root zone. Allow excess water to drain from containers and account for nutrients in the soil or compost.
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.

GREEN24 · Plant knowledge
From tendril to grape bunch
Tendrils hold young shoots to supports. Cultivar, pollination, pruning and climate contribute to fruit set.
Foliage and habit
Alternate, usually palmately lobed and toothed leaves. Tendrils grasp support; leaf size and autumn colour vary by variety and species.
Flowers and development
Tendrils hold young shoots to supports. Cultivar, pollination, pruning and climate contribute to fruit set.
Fruit development
Grape bunches comprise many individual berries. Dessert and wine cultivars differ in size, skin, seeds and flavour; site and warmth affect whether crops ripen fully.

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 young and container vines in dry weather. Water thoroughly as needed and allow drainage; rainfall may not reach roots beneath roof overhangs.
LeavesAlternate, usually palmately lobed and toothed leaves. Tendrils grasp support; leaf size and autumn colour vary by variety and species.
Tendrils hold young shoots to supports. Cultivar, pollination, pruning and climate contribute to fruit set.
Shoots and habitDeciduous woody climbers; the trunk and framework arms remain for many years.
Climbing shoots can cover several metres in a season. Train them deliberately along a support and keep the fruit zone accessible. Containers, trellises and pergolas need different trunk heights and training forms.
Fruits and seedsGrape bunches comprise many individual berries. Dessert and wine cultivars differ in size, skin, seeds and flavour; site and warmth affect whether crops ripen fully.
For an identified edible vine, test a berry for sweetness and cut ripe bunches with their stalks attached. They will not become sweeter after picking. Store only sound, undamaged bunches.

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 young and container vines in dry weather. Water thoroughly as needed and allow drainage; rainfall may not reach roots beneath roof overhangs.
In the garden
A sunny, warm position with strong support and airflow. Provide a draining root zone without persistent waterlogging; match rootstock to soil. In challenging climates, choose carefully for ripening time and frost tolerance.
Winter and rest
Protect container roots from severe cold without letting the root ball dry completely. While leafless, assess the framework and suitable fruiting wood for pruning.
Planting and repotting
Choose a stable container and clear drainage. Retain root-ball depth, keep the graft union exposed and allow for initial nutrients.
Observe and identify the cause
Powdery and downy mildew
Record whitish coatings or unusual spots on both leaf surfaces. These are different diseases; variety choice, airflow and reliable diagnosis come before treatment.
Grey mould and damaged bunches
Inspect dense, injured or persistently damp grape clusters. Remove affected berries and dried fruit remains without unnecessarily injuring sound grapes.
Mites, grape moths and phylloxera
Leaf galls, webbing or feeding damage call for closer identification. Seek specialist advice if phylloxera is suspected; choosing a suitable rootstock starts when buying the vine.
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.
