Many flower friends will buy some potted Dendrobium online and keep them at home. But the potted plants given by others are very lush, and they will become ugly after being maintained in their own hands for a period of time. Either the leaves are dry or the stems are white. What the hell is going on here? In fact, a large part of this is caused by improper watering. So how should Dendrobium be watered? Are there any other watering techniques? Today, Wall Valley will study with you!
What are the watering problems?
As soon as my friends see the flower valley, I say there is something wrong with watering. They will definitely think that it is their own way of watering, right? Is there too little or too much water? In fact, not only water quantity, water quality and air humidity are also important reasons for Dendrobium's poor growth!
How to water Dendrobium?
Water quality treatment
Living in the city, how can we water the potted Dendrobium? The first thing we need to pay attention to is water quality. Urban tap water contains a lot of disinfectants, which are harmless to human health, but generally we need to boil it before eating it. After boiling, harmful gases such as chlorine will be reduced.
If we directly water Dendrobium with tap water, it will easily lead to dry leaves and white stems. This is why the quality of tap water is not suitable for direct irrigation. We usually water the flowers in flowerpots or buckets with tap water and expose them to the sun on the balcony for one to three days before using them. After contact with tap water, chlorine and other substances harmful to plants will decrease.
Of course, we can also water Dendrobium with cold boiled water, just as it is not easy for us to grow floating objects when we cultivate hydroponic plants with cold boiled water, so it is safer and more effective to water Dendrobium with cold boiled water!
Watering skill
Water quality has been treated and improved. How should we water the flowers? Of course, we thought we could just pour it into the flowerpot. It's too simple! It is more appropriate to water Dendrobium according to the growth law. Dendrobium likes to grow in a humid environment without stagnant water. If we water the substrate frequently for a long time, it will lead to root rot. In the long run, it will lead to a large number of empty roots, which is very unfavorable to the growth of Dendrobium.
Every time we water it, we should observe it first. When we saw that the substrate was almost completely dry, we watered it. If we casually lift a layer of bark or other substrate on the surface, the bottom will still be wet. You must not water at this time! On the other hand, if we pick up some surrounding substrates and find that the bottom is dry, it means that they are almost dry and can start watering, otherwise, the longer the water shortage, the more likely Dendrobium Harrison will dry up or grow new leaves.
Of course, the timing of watering is not without trace. We water it on weekdays and then maintain it in the shade, which will not lead to water shortage for three or two days. If it is hot in summer, you can spray water to replenish water first, instead of watering the roots immediately, which can effectively avoid the occurrence of root rot. Generally speaking, it takes at least three to five days for Dendrobium nobile cultivated in the substrate to be completely dried. We can make a general judgment and then observe the situation in the matrix.
Moisturizing seedling raising
The best growth environment of Dendrobium should be about 80% air humidity. Summer and winter need more spray to cool and moisturize. If the temperature is too high, we need to spray water to increase the humidity of the air, reduce the temperature of the leaves and prevent the leaves from drying up due to excessive transpiration. The air is dry in winter, so we need to spray water to prevent the leaves from dehydration.
In summer, we need to spray water on the leaves or the surrounding air every day to cool down. Leaves that have not been sprayed with water for a long time will turn yellow and white at high temperature, and new leaves will not grow slowly.
The above are the watering methods and skills of Dendrobium introduced by Huaergu and some precautions. To raise Dendrobium, watering is a very important step. Water quality, quantity and watering method are indispensable. Dendrobium is so difficult to raise, we still have to raise it. What's a better solution? Can only do a good job of watering!
