Perhaps the orchid can be called one of the most popular flowers on our window sills. This amazingly beautiful plant needs proper care and dressing - in this case, regular flowering will be guaranteed! Her food should be balanced, and the conditions in which she grows are suitable for her. The five main elements that provide the orchid with beautiful green foliage and delightful flowers are nitrogen, phosphorus, potassium, magnesium and iron.
Nitrogen participates in the growth of the plant, without it the orchid practically stops growing, and the leaves become small. However, with an excess of nitrogen increases green mass, and flowering does not begin.
Phosphorus An orchid is needed to form flower stalks. With a lack of phosphorus orchids appear spots on the leaves, do not form and bloom. With an excess of this element, the leaves of the flower turn yellow, and the plant quickly ages.
Potassium enhances immunity and also participates in the formation of peduncles in orchids, contributes to long-term flowering. With a lack of potassium, the plant turns yellow and does not bloom. With an excess of orchid leaves can darken and become small.
Magnesium is the main element that helps the plant to participate in photosynthesis. With a lack of orchid leaves lose their rich color, become pale, the flower grows slowly and does not bloom. At the same time, the leaves darken and stop growing with an excess of magnesium.
Iron Also an important element for a flower. With a lack of leaves in the veins begin to turn yellow, and with a lack of - darken and cease to form.
Depending on what goal you are pursuing, this should be the dosage of fertilizer for orchids. The most important elements are nitrogen, phosphorus and potassium - is in the composition of complex fertilizers. If you want to increase the green mass of orchids, then choose the ratio of 4: 3: 3. If you need to stimulate flowering, the ratio will be as follows: 4: 6: 6.
