What is the hardest thing to grow flowers? I believe that every florist's answer is different, but it is meaningless to say that watering is extremely important in the process of growing flowers.
For example, orchids, there is an old saying: "Water orchids in three years." It can be seen how important it is to water flowers or green plants, and it is even more daunting to judge whether flowers need watering.
Here are four common ways to judge watering flowers.
Observation method
This is equivalent to observation and questioning in Chinese medicine, and it is also the most commonly used method to judge whether flowers need watering.
On the one hand, we can judge by observing the color change of the soil in the flowerpot: when the color of the soil becomes lighter or even whiter, it means that the soil is dry and should be watered in time; If the color is dark brown, there is generally no need to water it. If there is water or seepage on the soil surface, it means there is too much water.
If the water shortage of plants is too serious, the branches and leaves will wither and droop, the leaves will turn yellow and the flowers will wither and fall off.
Tactile method
Some experienced flower farmers, old farmers and vegetable farmers like to dig some soil with their fingers, judge the moisture in the soil by feeling the humidity with their fingers, and then decide whether to water it.
The method is also very simple: twist a small amount of soil. If the soil is easily ground into powder, it means that the soil is dry and needs watering. If the soil sticks to your fingers and is granular and difficult to disperse, you can temporarily not water it.
Some people don't water much, which makes their surfaces wet, but their hearts are thirsty. Then you can gently insert your finger into the soil below 2cm and feel the soil. If it is delicate and soft, it means that there is enough water.
method of specific gravity
This method is somewhat similar to picking watermelons. Tap the middle part of the flowerpot with your finger or a small stick. If the sound is crisp, it means that the soil is dry and needs watering. If the sound is dull, it means that the soil is wet and there is no need for watering for the time being.
But this method is more suitable for clay flowerpots. For plastic flowerpots, you can weigh them by hand. If they are lighter than normal, it means they need watering.
Tool method
The above three methods are relatively simple, but the conclusion is easy to be subjective, reliable and unreliable. After all, we can only make a general understanding through sensory judgment.
If flowers are more precious and you prefer to know accurate data, then you can buy a soil hygrometer or soil tester, the price ranges from 20 yuan to 100 yuan, which can be prepared to help you measure soil humidity, pH and even the illumination of the environment.
It is cost-effective to invest dozens of pieces at a time and easily control the watering of flowers.
