Roots are the basis of any plant at any stage of development, so in pursuit of an excellent harvest it is important to choose the right fertilizer.
If the root system is weak and poorly developed, then the above-ground part of the plant will not differ much.
It is carried out when the seedlings reach the stage of 2-3 true leaves, or after picking. The emphasis is on fertilizers with phosphorus and potassium. Phosphorus is responsible for the healthy development of the root system.
Potassium strengthens the immune system. The macronutrient is also necessary for the synthesis of proteins, which help seedlings fight stress.
Therefore, for the first feeding, use monopotassium phosphate - 10 g per 10 l of water.
In this case, nitrogen is added to phosphorus and potassium. Its source, for example, is ammonium nitrate. Liquid fertilizer is prepared - 10 g per 10 l of water.
It consists of nitrogen, phosphorus and potassium, and magnesium is also added. For example, summer residents prepare a mixture of ammonium nitrate (5 g), monopotassium phosphate (5 g), magnesium sulfate (5 g). Fertilizers are dissolved in 10 liters of water and seedlings are watered on moistened soil.
These three fertilizers will help strengthen the seedlings. The seedlings will grow stronger roots and will better fight diseases.
