How to preserve the beauty of orchids: the basic rules of care

  • Air. The homeland of exotic flowers is the tropics, so they need high humidity. Otherwise, the tissues of the petals dry out and wither quickly. During the heating season, when the air is particularly dry, the batteries should be covered with wet napkins, and bowls of water should be placed near the plants.
  • Draft. Heat-loving orchids do not accept through cold air – even a short-term decrease in temperature below +7°C can cause the death of plants. During ventilation, remove the pots from the windowsill, and if the street thermometer shows less than +15°C, it is not recommended to open several windows at once.
  • Lighting. You want to put a beautiful orchid in a prominent place in order to get aesthetic pleasure and attract the admiring glances of guests. Such a place should be near a window, because orchids like long daylight and bright lighting, but without the influence of direct sunlight. In winter, plants require artificial lighting, especially such varieties as Vanda, Cattleya, Cymbidium.
  • Fertilizing. For additional nutrition, it is advisable to use a specialized fertilizer for orchids, because delicate flowers need a reduced dosage of active substances. Plants are fertilized regularly during the growing season and flowering period – it is at this time that the soil becomes depleted especially quickly.

To apply fertilizer correctly, the pot should be immersed in a container with ordinary water, pour the soil with a nutrient solution prepared in advance and leave for 15-20 minutes. After feeding, excess solution should be removed from the tray.

Optimal fertilizer for orchids

For the healthy development of an orchid, a complex of NPK – nitrogen, phosphorus and potassium is required. Compositions with increased nitrogen concentration activate the growth of green biomass. Fertilization with an increased dose of phosphorus is recommended during the formation of flower stalks and blooming of buds. Potassium in all periods helps to strengthen the roots and increases the resistance of plants to various diseases.


The best fertilizers for orchids are specialized liquid solutions. Very convenient feeding in the form of applicators, which gradually release nutrients into the soil. If you use a universal fertilizer for flowering plants, consider that the indicated dosage should be reduced by at least 2 times, since orchids do not tolerate high concentrations of active substances.

Remember, only with proper care you will be able to admire your own garden with wonderful blooming orchids.
