What should be noted when transplanting ginkgo trees? Please guideThe points to note when transplanting ginkgo trees are divided into the following for reference:
1. Selection of ginkgo seedlings:The seedlings are required to be robust, with well-developed root systems, whitish xylem, and slightly reddish root bark that clings tightly to the xylem. If the root system turns black, the tree may already be dead even if the trunk still appears green. For street trees, seedling-grown plants or male plants should be preferred, with relatively straight trunks, uniform tree shapes, and branching points at around 3 m.
2. Planting of ginkgo trees:Planting before bud break in early spring makes it easier to survive. The planting soil should be deep and fertile, with organic matter content of 1% to 3%, and good air and water permeability. Place decomposed organic fertilizer at the bottom of the pit, then add 20 cm of mature soil and mix thoroughly to avoid burning the roots. If the weather is dry, fill the planting pit with water and plant after the water has drained away. Ginkgo is usually planted with a soil ball. Ginkgo does not easily develop roots when planted deep, so shallow planting is preferable, usually with the original root collar line level with the ground or 1 cm to 2 cm above it.
3. Water and fertilizer management methods for ginkgo trees:Water 5 to 7 days after planting. After ginkgo survives, it does not need frequent watering. Generally, the first watering is done after the soil thaws and before bud break. In May, if the weather is dry, a second watering can be given to benefit the growth and development of ginkgo.
During the rainy season, watering can be done depending on the weather. Ginkgo is drought-tolerant and afraid of waterlogging, so drainage should be attended to on rainy days. Because ginkgo roots have a high respiration demand, prevent root rot and death caused by excessive water and lack of oxygen in the soil. Fertilize in spring and autumn, applying decomposed organic fertilizer once outside the tree canopy using the ring fertilization method or the hole-punching method, then water after application.
Ginkgo has the phenomena of false survival and false death. Some ginkgo trees can still unfold leaves even if the root system has died, and may even sprout in the second or third year, but the leaves are very small. Only when the nutrients in the tree are exhausted does it stop producing leaves. This is the false survival phenomenon of ginkgo.
After some ginkgo trees are planted, they do not sprout in the first year, or even in the second year, but the bark remains fresh green, and only in the third year do they begin to sprout and unfold leaves. This is the false death phenomenon of ginkgo. Therefore, some people say: when planting ginkgo trees, surviving for three years does not count as alive, and dying for three years does not count as dead.
4. Pruning and pest and disease control methods for ginkgo trees:Ginkgo does not require special pruning. Before transplanting, trunk-setting pruning can be carried out, and at the same time, overly dense branches, diseased and pest-infested branches, damaged branches, and dead branches should be cut off. During its growth process, because growth is slow, pruning is generally not carried out.
During maintenance, timely intertillage and weeding are needed to reduce weeds, which is beneficial to tree growth. At the same time, it improves soil aeration conditions, promotes root growth, and encourages new roots to sprout.
Ginkgo trees have very few pests and diseases. In years with high summer temperatures and drought, seedlings of the current year or newly transplanted seedlings are prone to scorching at the stem base, allowing pathogens to invade, and rot disease is likely to occur after rain. In summer, shade nets can be set up or Bordeaux mixture can be used for control.
The main pest of ginkgo trees is white grubs. Ginkgo cultivation is simple and management is extensive, making it an excellent landscaping tree species. Management after ginkgo transplanting is very important, but the soil porosity at transplanting and the ratio of root size to the amount of branches and leaves retained can also affect the survival rate of ginkgo transplanting.
