When we choose the flowers for a sunny balcony we must pay close attention to the needs of the plant, because not all species can survive daily exposure to sun rays, especially during the summer.
We must say that the plants bear the heat in different ways depending on the surrounding. In reality, on a balcony overlooking the street surrounded by building, our plants will be more stressed by the sun, rather than being in a garden, even a sunny one, but in the middle of the lawn and even better shaded by shrubs or higher plants.
Always have more new soil and make sure it’s always damp. When watered only use room temperature water, and be careful not to get water directly on the leaves as this could change extreme temperature changes and damage the plant.
It’s recommended to water late in the evening, when the temperature is lowered, and if you add a cap of liquid manure every time you can ensure blooming until the fall.
