In simple terms
It places greater emphasis on new green growth, while phosphorus, potassium and trace elements complete the plant's nutrition.

A water-soluble fertiliser with a high nitrogen content for plants in active growth that are producing new leaves or shoots. For home use, dissolve it in water and apply it mainly by watering potted plants at the root. It can also be applied as a foliar spray, using a different dose.
In the 30-10-10 formula, the first number represents nitrogen. Here it is higher than phosphorus and potassium, making this formula suitable when the main aim is the development of leaves and shoots.
It places greater emphasis on new green growth, while phosphorus, potassium and trace elements complete the plant's nutrition.
If you want a balanced general-purpose fertiliser rather than a strong emphasis on new vegetative growth, see Nutrileaf 20-20-20 below.
Suitable when a plant is producing new leaves and shoots or restarting active growth.
For potted plants, ornamentals, vegetables and trees that need a fertiliser with more nitrogen.
Water at the root to feed potted plants, or spray the leaves using the separate foliar dose.
You do not need technical terminology: consider whether your main aim is new leaves and shoots. If it is, 30-10-10 is the higher-nitrogen option in the range.
When they begin active growth and need support for leaves and shoots.
For ornamentals, vegetables and trees during periods of new vegetative growth.
Apply dissolved in water to the growing medium around the roots while the plant is actively growing.
When the plant returns to active growth and begins producing new leaves.
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.

Nutrileaf 20-20-20 1Kg provides equal proportions of nitrogen, phosphorus and potassium for broader supplementary feeding.

Quick answers on what it does, how much to put in the watering can and when to choose foliar spraying.
It has a high nitrogen content and is used when you want to support the development of new leaves and shoots. It also contains phosphorus, potassium and trace elements.
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, vegetables and trees during new vegetative growth when they need a fertiliser with more nitrogen.
Choose 30-10-10 when the main aim is new leaves and shoots. For more balanced general feeding without such a strong emphasis on nitrogen, choose Nutrileaf 20-20-20.
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.
