A controlled-release fertilizer for flowering annuals, balcony pots and compact seasonal plantings. Its formula is designed to support abundant flowering, tidier compact growth and a better-looking plant for weeks, without the need for constant repeat feeding.
Formula: 13-7-18 + 1.5 MgO + TELongevity: 2-3 months @21°CFor flowering & compact growthControlled releaseMix-in or top dressing
Made for flowering annuals: the higher potassium level helps support stronger flowering and a more compact, balanced shape.
More practical feeding: it works gradually for up to 2-3 months, so you do not need to fertilize as often.
Better distribution in small pots: the fine granule size helps it spread more evenly through the growing media.
Well suited to seasonal displays: ideal for plants with a short, intense cycle of growth and bloom.
How to use it
Main use: mix it evenly into fresh potting mix before planting or repotting.
Also suitable on the surface: you can apply it on top of the soil in a small, even amount as a top dressing.
If the soil is already fertilized: start more cautiously so the plant does not receive more feed than it needs.
Water after application: a good watering helps the gradual nutrient release begin properly.
Measure the rate: choose a light, normal or higher rate depending on the plant and the potting mix.
Apply it: either mix it into the soil or spread it evenly on the surface around the plant.
Water well: the fertilizer starts working gradually and continues for weeks, depending on temperature.

Ideal for: petunias, surfinias, geraniums, calibrachoa, flowering annuals and, in general, bloom-focused plants in pots and planters.
Helpful note: this product is designed to feed gradually through the plant’s active cycle. If your soil already contains fertilizer, start with a lower rate.
How much should I use?
For general use, a safe starting point is 2-3 g per litre of potting mix. For lighter feeding, start at 1.5-2 g/L, while heavier flowering plants can go up to 3-4.5 g/L.
Can I apply it on top of the soil?
Yes, it can also be used on the soil surface as a top dressing. However, the main and most even application method is to mix it into the growing media.
How long does it last?
The stated longevity is 2-3 months at 21°C. In cooler conditions it lasts longer, while in warmer conditions nutrients are released faster.
Do I need another fertilizer as well?
In most cases, no, especially when it is used correctly from the start. If the plant has a much longer growing cycle, or if the potting mix and water require correction, additional feeding may be needed later on.
