Summer is the time of active growth of orchids. In the warm season, all life processes are activated – leaves grow, flower stalks develop, orchids bloom. But if there is a strong heat outside the window and the scorching rays fall on the flowers, the risk of losing a delicate phalaenopsis or another type of orchid increases.

To protect orchids from burns, remove flowers from windowsills where the sun’s rays fall for a long time. In hot weather, move plants to shady spots on nightstands, tables, shelves, and racks. You can even put pots on the floor.

If there is no suitable place, leave the orchid on the windowsill. But put protection on the glass. Both a special shading film and a thick sheet of paper will do.

Perfectly protect from the scorching sun blinds or roller blinds.

Control the temperature and humidity of the air in the room.

If your home has air conditioning, turn it on. This will benefit the plants. But just make sure that they are away from the flow of cold air.

If a cooling device is not available, ventilate the room more often, preferably at night when the temperature drops.

Pay special attention to watering. In the heat, orchids need more water, they have to be watered more often. When the temperature rises, more moisture evaporates and the roots dry out faster.

Water not according to a specific schedule, but depending on the needs of the flower.

It’s time to water orchids if:

  • the substrate in the pot has dried up,
  • roots are light green
  • inside, single drops of water are visible on the walls of the pot,
  • the pot became light.

For watering, use soft settled water. But do not overdo it with watering. This is the most common reason for the death of orchids.

How to save an orchid in a hot summer

If for some reason the orchids have been without water for a long time and the leaves have become lethargic and wrinkled, do not rush to get upset. A dried plant can really be saved.

Put the pot in water and hold for a few hours longer than usual. For more severe “dehydration” of the plant, leave the planter in the water overnight. Until the moisture nourishes all the tissues of the plant, the situation will not change. But on the 2-3rd day there will be a positive trend.

Remember that only orchids with a strong and healthy root system can be abundantly saturated with moisture.

In the case of waterlogged orchids, on the contrary, drain the excess water from the pan and limit watering for a while. Place your tropical beauties planter in a shady spot.

Move the overheated orchid to a cooler shady place for several hours. Just do not water or spray such a flower right away! This can cause the roots to die and the leaves to turn yellow. It will take 3-4 days for the plant to recover. Please note that it may not withstand the second overheating.

If the sun burned the leaves of an orchid, do not despair, the situation is also fixable. Examine the burn site. If it is small and dry, you should not cut this sheet. Gradually, it will dry up and fall off on its own.

If the place of the burn began to turn black and moisture appeared there, immediately cut off such a sheet. These are signs of decay, which can spread to the entire flower and cause its death.
