Does the Ginkgo biloba tree need to be watered frequently?
Sharing topics related to whether the Ginkgo biloba tree needs to be watered frequently and the cultivation essentials of Ginkgo biloba will surely bring you help. Let's learn about it together! Every autumn, the sight of "yellow Ginkgo biloba leaves covering the ground" is always unforgettable, but although the Ginkgo biloba tree is beautiful, it is not easy to cultivate. Since it takes a long time to grow large Ginkgo biloba trees, they often need to be transplanted multiple times to meet the specifications. However, there is an acclimatization period after each transplant, which can last from half a year to two years or even longer. Sometimes, phenomena such as "not really alive in the same year and not really dead in the same year" can even occur. Therefore, improving the transplanting techniques of large Ginkgo biloba trees is crucial. The editor will now introduce the key points of transplanting Ginkgo biloba trees, hoping to provide help to everyone.
I. Selecting Seedlings
The seedlings should be strong, with well-developed roots, white xylem, slightly red root bark, and tightly adhering to the xylem. If the roots turn black, even if the trunk is green, the tree may have already died. For street trees, it is better to choose between seedlings or male trees with straight trunks, consistent tree shapes, and branching points around 3 meters.
II. Planting
Planting in early spring before germination is easy to survive. The planting soil should be deep and fertile, with an organic matter content of 1% to 3% and good permeability. Place decomposed organic fertilizer at the bottom of the hole and then add 20 cm of mature soil to mix thoroughly to avoid root burn. If the weather is dry, fill the planting hole with water and let it drain before planting. Ginkgo biloba trees are usually planted with soil balls. Ginkgo biloba trees do not root easily when deeply buried, so it is best to plant them shallowly, usually with the original root line level with or 1 to 2 cm above the ground.
III. Water and Fertilizer Management
Water after 5 to 7 days of planting. Once the Ginkgo biloba tree has survived, there is no need to water frequently. Generally, the first watering is done after the soil thaws and before germination. In May, if the weather is dry, the second watering can be done to promote the growth and development of Ginkgo biloba. In the rainy season, water according to the weather conditions. Ginkgo biloba trees are drought-resistant but afraid of waterlogging. During rainy days, it is important to drain the water. Since Ginkgo biloba trees have a high root respiration rate, it is necessary to prevent root rot caused by excessive soil moisture and lack of oxygen. Fertilizing is done in spring and autumn, around the outer crown of the tree, using a ring fertilization method or by making holes, applying a decomposed organic fertilizer once, followed by watering. Ginkgo biloba trees have the phenomena of false alive and false dead. Some Ginkgo biloba trees can still unfold their leaves even if the roots are dead, and can even germinate in the second or third year, but the leaves are very small. When the nutrients in the tree are exhausted, it will no longer produce leaves, which is the false alive phenomenon of Ginkgo biloba. Some Ginkgo biloba trees do not germinate in the first year after planting, or even in the second year, but the bark remains fresh and green, and it starts to germinate and unfold leaves in the third year, which is the false dead phenomenon of Ginkgo biloba. Therefore, some say: "Planting a Ginkgo biloba tree, it's not alive after three years, and it's not dead after three years."
IV. Pruning, Cultivation, and Pest and Disease Control
Ginkgo biloba trees do not require special pruning. Before transplanting, they can be pruned to shape, and dense, diseased, injured, and dead branches should be removed. During their growth, they generally do not need to be pruned. In the maintenance process, it is necessary to cultivate and hoe the weeds in time, which is beneficial for tree growth, as well as improving soil aeration and promoting root growth and new root development. Ginkgo biloba trees have very few pests and diseases. In hot and dry summers, young seedlings or newly transplanted seedlings are prone to root base burns, which can allow pathogens to enter, and rot diseases can occur after the rain. In summer, sunshades can be set up or Bordeaux mixture can be used for prevention. The main pest is the grub. Ginkgo biloba trees are easy to cultivate and manage with a simple approach, making them excellent绿化树种 (landscape trees). The management of Ginkgo biloba trees after transplanting is important, but the porosity of the soil at the time of transplanting and the ratio of root size to the retention of branches and leaves can also affect the survival of Ginkgo biloba transplants.
