The excellent seed-collecting mother trees with strong growth and no diseases and insect pests were selected and began to be collected around September when the seeds were fully mature. The seeds of Cornus officinalis have the characteristics of deep dormancy, hard core, containing a transparent mucus resin, impervious to water and air, affecting seed germination. Therefore, seed germination must be carried out before sowing. The treatment methods include chemical treatment method, stratification sprouting method, human feces and urine heap method, nursery surface burning method and so on.

The sandy loam soil with flat topography, fertile soil and good drainage is selected as the nursery land, which is ploughed deeply with sufficient bottom fertilizer in winter, and the base fertilizer is better with stable fertilizer and plant ash. Make a bed after shallow ploughing and raking before raising seedlings in spring. Soil disinfection should be carried out in the nursery land where mole cricket, grub and other underground pests are easy to occur. Propagation method of Cornus officinalis

Spring sowing is usually carried out after soil thawing from February to March, while autumn sowing is usually carried out before soil freezing from September to November. Using the strip sowing method, the row spacing is 20 to 30 meters, and the ditch depth is 4 to 5 meters. After watering and sowing in the ditch, the soil is covered with 2 to 3 meters and covered with wet grass.

The seedlings can emerge about 25 days after sowing, and when the seedlings are unearthed up to 70%, the covered grass on the seedbed should be removed 2 to 3 times. If the height of the seedling is more than 10 cm, the seedlings can be fixed and fertilized properly when the height is 20 cm. After the seedlings enter the fast-growing period in July, the management of fertilizer and water should be strengthened. In September, in order to accelerate its Lignification, we should stop applying nitrogen fertilizer and increase the application of phosphorus and potassium fertilizer. The seedlings can come out of the nursery when they are as high as 60 to 100 centimeters.

Dogwood borer, one of the most serious pests of dogwood is the dogwood borer, which is a caterpillar that tunnels into the trunk of a tree. Weak branches and old trees are the most prone to moths. If it is found that dogwood tree drops, it may be a more obvious symptom. Once these destructive pests such as moths are in the tree, they are difficult to eradicate.

Shell insects are nasty bugs that affect the growth of dogwood. They can secrete a sugary liquid called honey, which can cause leaf droplets in heavy rainfall. Large-scale infestation is more destructive than other pests. Using soap is an effective insecticidal treatment for this problem.

Tree aphids, aphids usually affect ornamental trees, they will absorb dogwood juice. They also secrete honey, which can be easily recognized. Neem oil is a good way to control aphids on trees, or you can use homemade organic control solutions.

Dogwood sap, not all dogwood problems are the result of pests and diseases. Cornus officinalis sap can also result in improper pruning. Sometimes Cornus officinalis is injured by other causes, such as storm damage. Because Cornus officinalis is known to have "bleeding", sap should be released from the wound.
