A fully water-soluble fertiliser with equal proportions of nitrogen, phosphorus and potassium for the general feeding of potted and garden plants. For home use, dissolve it in water and apply it mainly by watering at the root. It can also be applied as a foliar spray, using a different dose.
In the 20-20-20 formula, nitrogen, phosphorus and potassium are present in equal proportions. It is the balanced option in the range when there is no need to focus only on vegetative growth, flowering or fruiting.

If the main aim is new leaves and shoots and you need a stronger emphasis on nitrogen, see Nutrileaf 30-10-10 below.
A balanced option for plants in active growth that do not need a specialised formula.
For potted plants, ornamentals, vegetables, flowering plants and trees.
Water at the root to feed potted plants, or spray the leaves using the separate foliar dose.
You do not need to choose a formula that emphasises only one nutrient. The 20-20-20 formula suits the general care of plants in active growth.
For the general feeding of indoor, balcony and terrace plants during active growth.
For ornamentals, vegetables, flowering plants and trees that need balanced supplementary feeding.
Apply dissolved in water to the growing medium around the roots while the plant is actively growing.
When there is no specific target and you want equal proportions of nitrogen, phosphorus and potassium.
Root watering and foliar spraying use different doses. For potted plants, start with the watering dose.
To feed potted plants, dissolve 0.5–1 g in each litre of water. Use 0.5 g/L for small or more sensitive plants and up to 1 g/L for large, vigorous plants in active growth.
Use 2.5–5 g in 5 litres of water, or 5–10 g in 10 litres of water.
If you choose foliar spraying, dissolve 2–4 g in each litre of water and spray the leaves evenly.
Put some water in the watering can or sprayer, add the measured amount, mix well and top up with the remaining water.
For foliar spraying, choose the morning or late afternoon and avoid strong sun and high temperatures. Do not mix it with oils, sulphur, Bordeaux mixture or alkaline products. If you are unsure about a combination, use it on its own.
One pack contains 1 kg of water-soluble fertiliser.
Used mainly by watering potted plants at the root and may also be applied as a foliar spray.
Keep the pack tightly closed in a cool, dry place, away from direct sunlight and heat sources. Keep it away from children, avoid contact with eyes and skin, and do not exceed the recommended dose.

Quick answers on general use, the watering-can dose and the difference from 30-10-10.
It provides nitrogen, phosphorus and potassium in equal proportions, together with trace elements. It is the balanced option in the range for general supplementary feeding during active growth.
For root watering, dissolve 0.5–1 g of product in 1 litre of water. Use 0.5 g/L for small or more sensitive plants and up to 1 g/L for large, vigorous plants in active growth.
For foliar spraying, dissolve 2–4 g of product in 1 litre of water. This equals 10–20 g for a 5-litre sprayer or 20–40 g for a 10-litre sprayer.
It is suitable for potted plants, garden plants, ornamentals, flowering plants, vegetables and trees in active growth that need balanced feeding.
Choose 20-20-20 for balanced general feeding. Choose 30-10-10 when the main aim is new leaves and shoots and a stronger emphasis on nitrogen is needed.
Put some water in the watering can, add the measured amount, mix well and top up with the remaining water. Water the potting mix, preferably when it is already slightly moist, and do not use it at every watering.
