Is it good to spray plant leaves with water every day? Analysis of the causes of blackened flower leaves

In hot weather many people drink more water, so many flower growers think that people and flowers are alike, and because water evaporates quickly in the heat, they diligently spray plant leaves with water to increase humidity and cool them down. However, the characteristics of plants are fundamentally different from those of people, so do not presumptuously spray your plants with water anymore. Below we have compiled some common plants that must not be sprayed with water.

Common plants whose leaves rot when sprayed with water include hydrangea, gloxinia (Sinningia speciosa), Cuban oregano (Plectranthus amboinicus), and geranium. They are all among the best-selling flowers on the flower market, and they share one characteristic: their leaves are covered with fine, dense tiny hairs, so most of the water cannot be absorbed by the roots and can only remain on the leaves; over time this clogs the leaves, and the eventual bad results are problems such as rotting stems, rotting roots, and black rot.
Also, another type whose stems rot when sprayed with water includes Rieger begonia and wax begonia. Their characteristic is thick, rather fleshy stems; usually plants with fleshy stems do not need too much water, simply because they can already store water inside themselves. Once, when they are full of water, you spray them with water without even realizing it, the result is problems of rotting stems and rotting leaves.

By the same reasoning, there are also some plants with fleshy leaf stalks, such as cyclamen and violet. Their growth form is a rosette of leaves clustered at the base, and their leaves are also covered with fine, dense hairs. Both of these characteristics help them reduce water evaporation. Therefore, if you still spray them with water in daily care, this may cause problems such as rotting leaves and rotting roots. In addition, during the rainy season be careful not to pour water on them anymore; it is recommended to manually add some sand at the bottom of the pot or mix it into the potting soil to improve their drainage performance.

In addition, there are also plants with multiple "leaf cores" such as orchid, clivia, and amaryllis, because their characteristic is that new leaves and flower scapes emerge from the leaf core and grow upward. So if you spray water on their leaves, the water will flow along their leaves into the leaf core, and when the water accumulates in the leaf core and cannot evaporate, it easily leads to core rot.
