Phosphorus is one of the elements that a plant needs at all stages of its development.
Most often, according to the expert of the online publication BelNovosti, scientist-agronomist, landscape designer Anastasia Kovrizhnykh , it is young plants that suffer from a lack of phosphorus.
How to recognize phosphorus deficiency
A lack of phosphorus manifests itself as blueing and darkening of the leaves of seedlings.
If you notice that the leaves of young seedlings first become emerald green, dark, after which the stems acquired a purple color, and the back of the leaves began to turn blue, it becomes clear without words - you had to deal with a deficiency of this element.
If you notice any of these signs in the plants you grow, take action as quickly as possible.
Blueness of seedlings, indicating a lack of phosphorus, inhibits the growth of leaves, stems and shoots.
How to help seedlings
As a rule, phosphorus deficiency, which appears at the seedling stage, is a consequence of cold soil. Therefore, to solve the problem, try moving the containers with seedlings to a warmer place, where the soil temperature reaches +15-20 degrees.
Foliar feeding or root watering with phosphorus fertilizer will also help.
To prepare the fertilizer, you will need to dissolve 1 g of potassium monophosphate in a liter of water.
