Multi-knowledge: Sowing seeds on the windowsill
The gardening season doesn't just begin in spring—it often starts in the middle of winter on the windowsill. While there is still snow outside, the first tender green shoots are already sprouting indoors. For many hobby gardeners, sowing seeds is one of the most enjoyable activities of the year. No wonder: home-grown plants are more robust, cheaper, and often more diverse than most young plants from the garden center.
When growing plants, high-quality sowing soil, EM ceramic powder, organic plant aids such as Roots and Plants, and the right sowing time play an important role. There are many professional tricks that experienced hobby gardeners use for this.

Why sow seeds on the windowsill?
Growing young plants yourself has numerous advantages:
Retailers often only stock a small selection of common varieties. With seeds, on the other hand, you can grow unusual tomato varieties, colorful peppers, special herbs, and flowers that are otherwise hard to find.
Young plants grown using EM adapt to their environment right from the start and are more robust. This makes them less susceptible to disease and more resistant to stress from wind, sun, and drought.
A paper bag of seeds often costs less than a single young plant. In addition, sowing seeds indoors saves on plastic packaging and energy for heated greenhouses. And for those who find the dark season difficult, sowing seeds on the windowsill brings a touch of spring into the living room.
The perfect start: high-quality seed compost
The soil is the basis of every successful sowing. It should be fine and homogeneous, light, structured, and permeable, but with good water retention. It should also be low in nutrients, as young seedlings cannot process too many nutrients—the seedlings will become leggy. Multikraft Organic Black Soil for Flowers and Herbs is ideal here.
In addition to standard seed trays and pots, egg cartons or old yogurt cups with drainage holes in the bottom are also suitable. Fill the containers with seed compost and press the soil down lightly before sowing according to the instructions and covering the seeds lightly with soil (except for light-dependent germinators!). EM ceramic powder is used.
EM ceramic powder: Root power from nature
EM ceramic powder stimulates root formation, improves soil structure, and makes young seedlings more resistant. Simply mix a teaspoonful of ceramic powder with the seeds and then sow. When pricking out, dip the roots in a little ceramic powder.
After sowing, lightly moisten the whole thing with a spray bottle. You can increase the humidity with plastic wrap or a clear lid. However, it is important to ventilate daily to prevent mold from forming. During the germination phase, the seeds should be kept warm, bright, and evenly moist. As soon as the seedlings have at least one pair of leaves, they can be transplanted.

Roots for strong roots
Roots supports root development after sowing and pricking out by stimulating fine root growth and improving nutrient uptake. This prevents repotting stress and ensures strong, compact plants. Use Roots diluted at a ratio of one cap per liter of water for watering and for watering after pricking out. Always water sparingly, according to the motto “moisture instead of wetness,” and use room-temperature water. Water that is too cold shocks the delicate roots.
Plants – Vitality spray for strong leaf growth
Window sill plants are often exposed to stress due to dry heating air, low light levels, and fluctuating temperatures. Plants, which strengthens leaves with effective microorganisms and fermented plant extracts, helps to counteract this stress by strengthening the cell structure, promoting photosynthesis, and supporting chlorophyll formation. Ideally, spray the leaves once a week with a dilution of 20 ml Plants to 1 L water.
Avoiding common problems
If seedlings become spindly, i.e., very thin, weak, and unstable, they are either too dark or too warm. Mold on the soil develops when the soil is too wet or there is poor air circulation. To prevent fungus gnats, the soil should not be kept too wet. Fungus gnats hatch from eggs in contaminated soil. Using high-quality potting soil or sterilizing the soil in the oven, for example, can help.

Conclusion
Sowing seeds on the windowsill is worthwhile, as plants are strengthened with effective microorganisms right from the start. With high-quality sowing soil, gentle organic plant strengtheners such as EM ceramic powder, Roots and Plants, and a little patience, you can grow strong young plants that will later yield a rich and long harvest in the garden or on the balcony. A little knowledge, a few tried-and-tested tricks, and regular attention—that's all it takes for a successful start to the season.
