You can get bags with seeds in basically every florist, seed factory, garden house, drugstore or supermarket for the cheap price. When choosing, make sure that the seeds do not expire. You don't normally use all the seeds from the bag to sow in the box, so you'll have some left over for next year.
Once you have bought the seeds, also buy a suitable substrate for sowing and propagating plants, preferably one suitable for germinating plants. To transplant the seedlings, you can get the soil to grow seedlings, the price for a ten-kilo package is usually around twenty to thirty crowns. Today, you can also easily get a special substrate designed specifically for growing herbs, if you are just starting out with herbs, this substrate will make it much easier for you.
How to germinate seeds
At home, you can start germinating seeds in early March. Start germinating in closable containers with holes. This is very important for maintaining humidity. An room greenhouse, for example, is ideal for this, but an ordinary container is also sufficient. Humidity must be controlled - excessive moisture causes mold on the stands, on the contrary, in dry air the plants do not thrive and are stunted. In residential conditions, you germinate seeds much faster than outdoors. You must not forget to regularly grow the seeds so that they do not dry out and die. Once the sprouts are about 1 cm high, it is advisable to transplant them into the substrate.
Direct sowing into the substrate
If you do not want to germinate the seeds in a complicated way and then transplant them, all you have to do is buy a larger box or flower pots and a quality substrate for herbs. Then simply pour the substrate into a box and sprinkle the seeds thickly. It is important not to forget to grow herbs regularly every day. In both methods, the growing seeds are placed in a place where there is heat and enough light at the same time. In the summer months, be careful not to dry out, there are often high temperatures outside the window.
