How does water affect flower growth?

Water is an important component of plants; generally, the water content in a plant's body reaches more than 30%. Water is also one of the main raw materials for plant photosynthesis, and nutrients in the soil can only be absorbed by the plant body after dissolving in water.

In addition, because of the presence of water, plants can rely on transpiration through their leaves to regulate their internal temperature. Therefore, all kinds of physiological activities within the plant body must be carried out with the participation of water, and without water plants cannot survive. However, in nature there are many kinds of flowering plants with different habits, and different plants have clearly different requirements for water. Some can only grow in water, some can adapt to relatively long periods of drought, some need to grow in very humid places, and some like to grow in moist soil. Therefore, in cultivation, the special water requirements of various flowers must be taken into account and cannot be generalized. But overall, an appropriate water supply is the guarantee of normal growth and development for flowers.

Long-term excess water in the soil or insufficient water supply will both bring harm to flower growth. If there is long-term excess water in the soil, the air in the soil decreases, which will hinder root respiration and make the roots lose their ability to absorb water, causing root suffocation and rot, yellowing and falling leaves, and even plant death. If the soil lacks water, the water absorbed by the roots can hardly meet the evaporation of water from the leaf surface, and the leaves will wilt. When flowers are in a state of insufficient water supply for a long time, they must be watered and irrigated in time. Especially for some potted flowers, the volume of the pot is limited and the wet-dry difference is obvious, so attention should be paid to watering at any time and supplying evenly. Especially under conditions of high temperature and dryness, spraying water on the ground or on the leaves can also be used to increase air humidity and create a suitable microclimate for flower growth.
