Perhaps the most important component is proper flower care. Flowers love coolness, the ideal room temperature for them is 18-20 degrees. In a hot, stuffy room, flowers will wither much faster than in a cool, ventilated room. But you do not need to put flowers too close to the air conditioner, a draft can also be dangerous for flowers. Flowers should never be placed under direct sunlight. There is a common misconception that flowers love the sun. But, in fact, they begin to wither quickly under its influence.
