Does the stem always turn black after transplanting flowers rooted in water?
Today's topic is about the related issues of flower cultivation when the stem always turns black after transplanting flowers rooted in water. If there are any mistakes, please correct them!
Many flowers can be propagated by cutting in family cultivation, and among the propagation methods of cutting, water cutting is one of the simpler and easier methods. It is convenient to operate and manage, with a high survival rate and low technical requirements for cutting. Many flower lovers choose to use water cutting for propagation, such as water cutting roses, geraniums, dwarf morning glories, lucky trees, gardenias, and so on.
So, what should we do after the roots have grown in water? How to pot them to ensure the survival rate?
The method of water cutting has a high rooting rate, but the chance of black rot is also high when potting, because the young plants that survive after water cutting are transplanted with bare roots, and the huge environmental changes can easily cause the young plants to becomeunaccustomed and develop black rot.
Transplanting method after rooting in water cutting
No matter what kind of flower variety is transplanted after rooting in water cutting, it should be transplanted with simple soil first, which is soil without fertilizer.
Soil containing organic fertilizer has many bacteria, including beneficial and harmful ones. Therefore, if the soil contains organic fertilizer, it is easy for the young plants to get infected after transplanting and develop black rot. On the other hand, if the soil contains fertilizer, it can easily cause the young plants to suffer fertilizer damage, because the young plants that have just survived after cutting have weak fertilizer tolerance and are easily affected by fertilizer damage, leading to root damage and then black rot, resulting in failed transplantation.
In addition to soil selection, the method of transplantation is also very important. The root system of young plants from water cutting is relatively weak and easily damaged by external forces. When transplanting, if the conventional method of planting with dry or wet soil is used directly, the new roots can easily be damaged by the weight of the soil, leading to failed transplantation.
Therefore, it is recommended to use the "water absorbs soil" transplantation method when transplanting, using the buoyancy of water to buffer the pressure of the soil, which can well protect the new roots from damage.
Specific practice:
Find a water basin, place the flower pot in the water basin, add water to half of the flower pot, put the young plants with new roots into the flower pot, immerse them in water, and then slowly add the prepared simple soil into the flower pot, noting to add a small amount each time and not to add too much soil at once, otherwise it is easy to damage the roots.
In the process of adding soil, gently straighten the young plants until they can stabilize completely, then slowly add soil to 2-3 centimeters below the edge of the flower pot, and finally water thoroughly.
Then place the planted young plants in a bright and well-ventilated area with diffused light for slow seedling growth. The newly transplanted seedlings should not be exposed to direct sunlight, or they will easily wither. After a week of slow seedling growth, when the seedlings are stable, they can gradually be exposed to sunlight.
During the slow seedling growth period, if the potting soil is not dry and the leaves of the seedlings appear wilted, it is necessary to spray water supplement in time. Do not water easily, and water only when the surface of the potting soil is dry. At the same time, during the slow seedling growth period, it is necessary to maintain a well-ventilated environment to speed up the evaporation of excess water in the potting soil.
