Detailed Explanation of Viburnum macrocephalum Grafting Methods and Pest and Disease Control Techniques
Viburnum macrocephalum seedlings usually need 7 to 8 years to bloom. If they are grafted with branches from adult geranium flower buds, they can bloom in the very first year after surviving. How does the grafting method work? The following is suitable for everyone. Viburnum macrocephalum grafting methods and pest and disease control methods.
Viburnum macrocephalum Grafting Methods
1. Material Selection
This step is very important because it is related to the flowering time after grafting. If it is a seedling, then it can bloom after seven or eight years, so the wait is too long. However, if you choose an adult branch with flower buds, then once it survives, it can bloom in the very first year. Therefore, choose branches from a mother plant that is able to bloom, usually relatively peripheral ones above the crown.
2. Soil Selection
Although this plant has relatively strong adaptability and can be planted in general soil, plants grown in sand will have a more developed root system, so we should choose this kind of soil.
3. Timing Selection
Under normal circumstances, we choose early March, because this stage is when the buds sprout, and the temperature at this time is relatively suitable, neither cold nor hot.
4. Specific Steps
Cut about 5 cm in length from the selected branch, preferably using the terminal bud, and use the "high grafting" method for grafting. After completion, place it in a shaded environment or take appropriate shading measures. When the leaves grow out, they can receive sunlight.
5. Precautions
Due to the growth correlation between the main branch and the branches of this plant, we should cut off the top of the main branch after the side branches have been grafted. Doing so can accelerate the growth of the scion and also allow it to enter the flowering period more quickly.
Viburnum macrocephalum Flowering Time
When does Viburnum macrocephalum bloom? In fact, Viburnum macrocephalum blooms in April every year; when it blooms in May, the flowers can last about 20 days.
Pest Control Methods for Viburnum macrocephalum
1. Growing Season
Although Viburnum macrocephalum is not picky about the growing environment, this does not mean its growth rate is always consistent. Like all flowers, Viburnum macrocephalum can only grow quickly at a certain time, but we are happy about that. While it is growing, we must not forget that at this time, pests and diseases are actually the most dangerous organisms. If we frequently use fertilizer and the amount each time is very small, when the leaves are still yellow, we should understand that the cause is pests and diseases making the leaves unable to get nutrients.
At this point, we should take measures to treat pests and diseases. Generally, we choose a ferrous sulfate solution. If this solution is sprayed on the leaves, it will effectively kill the hateful pests, but attention must be paid to the ratio of the solution. If there is too much or too little, it is not good, so we must see that we need to use a one-thousandth solution.
2. Rainy Season
In fact, Viburnum macrocephalum itself is very susceptible to insect attack at that time. This is because its own very good characteristic is that its leaves actually have a lot of fuzz, so pests will not harm their roots, but despite its strong defensive function, its epidermis is its weak point, and the degree of keratinization here is not high. Therefore, some pests take advantage of this feature, and they can secrete certain substances, and these substances happen to be able to dissolve the keratin of this thin layer, which provides considerable possibility for the invasion of pests and diseases.
And this usually happens in the rainy season, so we should pay attention to the rainy season, and we must take strong measures to protect Viburnum macrocephalum. Our measure is generally to spray insecticide, which is a commonly used insecticide, so they do not need to worry about buying it. Its name is Bordeaux.
