The rate of seed germination and subsequent seedling development largely depend on the substrate in which they are sown. Previously, people prepared the soil themselves. Now, ready-made commercial soil mixes and special peat tablets are available. They contain all the necessary nutrients, but differ in the method and ease of use. Each has its pros and cons.
Advantages and disadvantages of soil
To ensure strong seedlings and abundant flowering in the future, the soil must be fertile and contain all the necessary nutrients. Soils with a balanced content of mineral components and easily digestible organic matter are suitable for flowers. Good soil remains moist for a long time. It should be environmentally friendly, free of toxins and heavy metal salts. Most crops benefit from neutral, light, and well-drained soil.

- soil from reputable manufacturers is completely ready for use;
- it retains moisture well, is loose, and contains all the necessary nutrients;
- it contains all the macro- and microelements necessary for plants;
- conveniently packaged in bags.
Disadvantages of ready-made soil mixtures:
- On the packaging of the ready-made soil mixture, the content of mineral components is indicated as a range without an exact dosage;
- acidity is also given as a range;
- Unscrupulous manufacturers add peat dust to the soil, which is unsuitable for growing plants.
The main component of universal potting soil is peat. It makes the soil more acidic and reduces its ability to drain. This causes many crops to grow weak and develop slowly. To improve store-bought soil, mix it with an equal amount of disinfected garden soil. To reduce acidity, add 2 tablespoons of dolomite flour for every 10 liters of soil. To improve moisture, add a few hydrogel crystals.
Advantages and disadvantages of peat tablets
To simplify seedling cultivation, peat pellets are used. They come in various sizes, making them suitable for many crops. In addition to a peat- and humus-based substrate, they contain antibacterial substances, mineral components, and growth stimulants. Seeds planted in pellets germinate quickly, develop a well-branched root system, and are more resistant to disease.
Before use, the compressed disks are placed in plastic trays, indented side up. They are placed close together and soaked in warm water. When the columns stop absorbing liquid, remove any remaining moisture with a sponge. Then, place 1-2 seeds in the center of each column.

Advantages of sowing seeds in peat tablets:
- Sowing takes a few minutes.
- There is no need to mix the soil yourself, disinfect it, or add fertilizers.
- There is no risk of damaging the roots of seedlings with a highly concentrated solution.
- Seedlings emerge uniformly and are less susceptible to disease. There is no risk of blackleg, as the pathogen does not survive in peat.
- The peat substrate provides good aeration of the root system.
- There is no need for picking.
- The mesh coating of the tablet does not interfere with root development, so it does not need to be removed.
- Planting in tablets allows for individualized care. Seedlings grow unevenly, so some plants require additional care. This is easier with individual peat posts.
Peat tablets have few disadvantages:
- Growing large quantities of seedlings is very expensive, as one tablet can only grow two plants.
- Peat-based substrate dries out very quickly, which can lead to plant death. Therefore, when growing this way, it's essential to constantly monitor the humidity level.
- Peat tablets require special containers in which the substrate is soaked and the entire growing process takes place.
- Plants still need soil for further development.
