How to Plant Viburnum macrocephalum? Detailed Planting Methods and Precautions

Viburnum macrocephalum may be relatively rare in our daily lives, and it is a particularly unique flower. Although Viburnum macrocephalum is not dazzlingly beautiful, its petals are as white as jade, elegant and refined, with a charming delicate fragrance, and it is deeply loved and sought after by everyone. As for planting Viburnum macrocephalum, many people do not know much about it. Below, the editor will introduce in detail some planting techniques for Viburnum macrocephalum!

How to Plant Viburnum macrocephalum

After the shell is removed, the seeds generally sprout in about 1 month. When the seedlings have just produced their first pair of leaves, they should be properly shaded. Especially at noon, do not let direct sunlight hit the seedlings, so as to avoid excessive transpiration and wilting of the young leaves. If the leaves are found to curl inward but recover immediately in the evening, it indicates that leaf transpiration exceeds root absorption, which is a common phenomenon under hot or dry conditions. Viburnum macrocephalum sown and sprouted in the same year does not grow quickly. From the second year, growth begins to accelerate noticeably. When it grows to more than 10 cm, the terminal buds can be removed according to the size of the pot to promote rapid growth of lateral buds and prepare for potted shaping and grafting.

Planting Methods and Precautions for Viburnum macrocephalum

1. Sowing method

The sowing time for Viburnum macrocephalum is generally around Qingming Festival. Take out the seeds collected the previous year, remove the hard outer shell, soak them in warm water for 24 hours, and sow after the shell has softened. Note that untreated seeds are difficult to sprout after sowing.

After sowing the seeds, they generally sprout in about 1 month. When the seedlings grow their first leaf, they can be properly shaded. It is best not to expose them to light at noon, so as to prevent water from evaporating too quickly and causing the seedlings to wilt.

If leaf curling is often observed but the leaves recover after evening, it indicates that the weather is dry and water is insufficient. During the day, water should be sprinkled frequently to increase air humidity.

2. Pruning method for Viburnum macrocephalum

Pruning is the most important step in the process of caring for Viburnum macrocephalum. After the remaining flowers fade each year, new flower buds differentiate. In March of the second year, flower buds begin to form. Therefore, after the flowers fade, a short pruning should be carried out to shorten excessively fast-growing branches and prevent the lower branches from becoming bare as Viburnum macrocephalum grows.

As Viburnum macrocephalum continues to grow, the branches gradually age, so timely heavy pruning should be carried out. Keep stout branches at 50 cm, and cut off all remaining crown branches to promote the sprouting of new branches.

3. Pest and disease control for Viburnum macrocephalum

During cultivation, Viburnum macrocephalum often shows yellowing leaves. Pay attention to supplementing phosphorus and potassium fertilizer in time, and spray ferrous sulfate solution once a week.

The leaves of Viburnum macrocephalum are covered with fine hairs, so they are generally not attacked by insect pests. However, bacteria can attach to the leaves, especially during rainy seasons. Therefore, Bordeaux mixture should be sprayed once a month, and ventilation should be maintained frequently.

How to Water Viburnum macrocephalum

If the upper layer of soil has already become somewhat dry, then it can be watered, and it should be watered thoroughly in one go. Do not water only halfway and leave the rest. Over time, this will cause the soil to clump and affect normal root growth as well as the normal absorption of water and nutrients. If you cannot judge whether it has been watered thoroughly, you can observe the drainage holes below. If water flows out, it means it has been watered thoroughly. When watering, pour slowly.

Too frequent watering or accumulated water in the pot can both cause its roots to rot. On rainy days, watering can be paused to prevent the water from being unable to evaporate, which would cause the soil to remain in a moist environment for a long time. In winter, the frequency of watering should be appropriately reduced. It is best to water in the morning or evening. Just after sowing, the soil must be kept moist, as this is beneficial for rooting and sprouting, and the frequency of watering can be increased.

Fertilization Method for Viburnum macrocephalum

Viburnum macrocephalum has very strong growth momentum and lush branches and leaves, so it cannot go without fertilization for a long time. During the peak growing season, fertilize once every 10 days, and the concentration should preferably be dilute rather than concentrated. Apply one topdressing after flowering, because a large amount of nutrients is needed during flowering, and if nutrients are not supplied promptly after the flowers fade, it will affect its growth and fruit formation.

Its fertilization should follow the principle of alternating dry and wet, meaning that when the upper layer of soil is relatively dry, it can be fertilized; if the upper layer of soil is still moist, then fertilization should be paused. Therefore, in daily cultivation, try to make a simple management plan and reasonably alternate watering and fertilizing.

Through the above content, I believe you have gained a certain understanding of the cultivation methods for Viburnum macrocephalum. If the care techniques are mastered well, Viburnum macrocephalum has a very long lifespan. Around April each year, it produces very beautiful white flowers, fresh and bright.
