A Detailed Guide to Ginkgo Tree Cultivation Methods and Sapling Planting Techniques
How do you cultivate a ginkgo tree? To grow a ginkgo tree well, management during the sapling stage is crucial. Below, the editor will briefly walk you through the techniques for growing ginkgo saplings.
If you want to plant a ginkgo tree, you should first know which planting method suits this tree. Growing ginkgo from seed is slow to show results, and the time it takes to mature is too long, so the results are poor. A more suitable planting method is planting saplings, which means selecting healthy, sturdy ginkgo saplings and finding suitable soil to plant them in. The saplings should be more than one year old; saplings that are too young and tender are also less likely to survive.
Now that the saplings have been chosen, you need to choose the soil. Ginkgo saplings like fertile, loose soil. So choose a place with fertile soil for planting, and never plant ginkgo trees in yellow earth or red earth. When planting, space them at least one meter apart; widening the spacing allows the ginkgo saplings to absorb nutrients better.
After planting, water promptly. Only with water and sunlight will the ginkgo tree take root and grow. The first watering should soak through; do not rush the second watering, and wait until the surface layer of soil is dry before watering. This is because newly planted saplings do not have many roots, so too much water is hard for them to absorb and, sitting in water, the roots rot easily.
It takes about half a month or so for the ginkgo sapling to take root and sprout; once the small tender shoots emerge, the ginkgo tree will grow quickly. During this period, you must ensure sufficient moisture. After a month and a half, you need to fertilize the ginkgo tree; you can use phosphorus-potassium fertilizer or organic fertilizer sold on the market. Do not apply too much fertilizer at one time; apply less but often, with a cycle of once every twenty days being better.
By autumn the ginkgo tree will bloom, and after blooming, stop fertilizing. But be careful not to let the ginkgo tree attract pests; usually after the flower buds form, one round of pest and disease control is needed. You can buy insecticide at a nursery stock market, dilute it with water, and spray it on the ginkgo tree. After the flowers have bloomed, the ginkgo will bear fruit, and after fruiting, do not rush to pick it. Wait until the fruit is ripe, and then you can enjoy the joy of a bountiful harvest.
Cultivation Techniques for Ginkgo Trees
Ginkgo is the oldest relict plant among extant seed plants. From planting to fruiting takes more than twenty years, and only after forty years can it produce fruit in large quantities; it can live to over a thousand years. Ginkgo is a deciduous tree, blooming in May and ripening in October; the fruit is an orange-yellow seed-like drupe. Ginkgo was originally distributed throughout the world, and after the Quaternary glaciation only remained in the subtropical mountainous areas of China. Today most ginkgo distribution belongs to artificially cultivated areas, mainly cultivated in large quantities in China, France, and the US state of South Carolina. Planting Methods1. Sowing and raising seedlings: Seeds should be collected large-grained; mother trees around 80 years old are best, and the collected seeds are peeled and dried in the shade. In the south, autumn sowing is possible; in the north, spring sowing is preferable. For the seedbed, choose sandy loam with good water permeability.
2. Using root suckers to grow nursery stock: Around February (after the ground thaws in the north), dig up suckering shoots with roots on one side at the base, and plant them in the nursery; diameters of 1 cm to 4 cm are all acceptable. This method is easy to succeed with. After about 10 years or so, they can bloom and bear fruit.
3. Cutting propagation: In May to June, select softwood shoots of the current year, cut them into 10 cm to 15 cm lengths, keep 3 to 4 leaves on top, insert half into the soil, and spray water frequently to keep the leaves from drying out; in about one and a half to two months they will root.
4. Seedling transplanting: Ginkgo with a diameter under 5 cm can be planted bare-root; those over 6 cm generally need to be planted with a soil ball. Bare-root planted seedlings have a recovery period that year. Seedlings with a soil ball can grow that same year. After small seedlings are planted in rows, irrigate by flooding. For planting large trees, it is best to fill the pit with water before planting; after the water in the pit has seeped away, plant the large tree into the pit and firm it, letting the water in the pit rise back up to moisten the roots. For the next watering, it is best to dig a diversion ditch at the edge of the pit and fill it with water, letting the water slowly seep through to the ginkgo's roots. Never flood-irrigate; the main reason many people fail to keep transplanted ginkgo alive is not that it died of drought, but that it drowned. Because the ginkgo root system has a high respiration demand, flood irrigation causes the roots to suffocate from lack of oxygen and fail to produce new roots, and the root system gradually rots. Even if some ginkgo trees die, their leaves can still unfurl, and they may even sprout again the second or third year, but the leaves are very small; only when the nutrients in their body are used up do they stop producing leaves. This is the ginkgo's "false life" phenomenon. Some ginkgo trees do not produce leaves the first year after planting, and may not even produce leaves the second year; if you pinch the bark, you will find the bark is fresh and the branches are not shriveled, so such a tree is not necessarily dead, and it may even produce leaves in the third year. This phenomenon is also called the ginkgo's "false death" phenomenon. To determine whether a ginkgo is falsely dead or falsely alive, you cannot look only at the leaves; what matters is looking at the roots. So when buying large seedlings, especially heeling-in seedlings purchased from elsewhere, you must check whether the roots have turned black; if so, it means the seedling is a falsely alive seedling, and no matter how cheap it is, you cannot take it. Fresh seedlings should have root xylem that is white, with the root bark slightly red and closely attached to the xylem.
5. Management of Seedlings
(1) After ginkgo survives, it does not need frequent watering. In northern regions, water once after the ground thaws and before sprouting; in May, if the weather is dry, water once, because this is ginkgo's growth peak of the year. In autumn, mid-August is ginkgo's second growth peak of the year, and you can water once; both waterings can be combined with fertilization.
(2) Fertilization: Fertilization in the nursery can be done in spring and summer. In spring, apply 5000 jin to 10000 jin of decomposed organic fertilizer per mu between the two rows, then rotary till once with a small rotary tiller so the fertilizer is evenly mixed into the soil. For large seedlings, several radial trenches can be opened, and organic fertilizer mixed evenly with topsoil can be filled into the trenches. If the amount of spring fertilization is large, once a year is enough; if the amount is small, apply an additional round in mid-August.
(3) Pruning: Ginkgo generally does not need pruning, because ginkgo produces few new shoots; even for nursery stock, you should keep as many branches and leaves as possible to help it thicken faster. In the year before the seedlings are to be sold, cut off branches below 1.8 m; after a year of growth, the cut wounds can fill in, the bark becomes smooth, and the trunk stands upright.
(4) Cultivation: Proper cultivation can improve the soil's aeration conditions. Cultivation also plays a pruning role for ginkgo's fibrous roots, which can stimulate more fibrous roots to sprout. Cultivating once each in spring and autumn is enough.
(5) Disease and pest control: The main ginkgo disease is damping-off at the seedling stage. The main pest of nursery stock in the field is the scarab beetle larva (white grub). At the seedling stage, pay attention to ventilation and moisture removal, loosen the topsoil, and spray Bordeaux mixture to prevent damping-off. The way to control white grubs is to apply fully decomposed organic fertilizer as much as possible. When fertilizing, spray the whole garden once with 3911 pesticide at 500 times dilution, then rotary till once, turning the pesticide-sprayed fertilizer into the soil. Another method is to moisten bran, rice bran, etc., mix in trichlorfon, store it in a bucket for two days so it fully absorbs the pesticide, then scatter it into the ground and cultivate. Yet another method is to bury a pile of dry grass about every 10 m, water the dry grass regularly, and every two months uncover the dry grass; underneath there will be many white grubs, which can be killed together.
(6) Cultivation of fruiting trees: Ginkgo is dioecious and cross-pollinated, so fruiting trees should be provided with pollinator trees. Ginkgo has strong pollination ability; under a breeze, a downwind area of 25 km is an effective pollination zone. The difference between male and female trees is: female trees have obvious whorled branching, branches spreading flat, and deeper leaf color, while male trees have upright, alternate branches. The planting spacing for a ginkgo orchard is 4 m × 6 m. Seedling trees grow fast; choose seedlings with a diameter at breast height of 3 cm to 4 cm, cut the top, and graft, generally by scion grafting. Choose 3-year-old scions with glossy bark color and 3 to 6 short branches, from fine varieties with large fruit, as the best choice. After grafting, they can bear fruit in 3 to 4 years.

Ginkgo originated hundreds of millions of years ago. The ginkgo trees alive today are rare and scattered, and old trees over a hundred years old are no longer commonly seen. How much do you know about ginkgo trees? Today the editor will briefly introduce the ginkgo tree price list and its characteristics.

Before learning about the ginkgo tree price list, the editor will introduce it. The ginkgo tree is also called the white fruit tree. It grows relatively slowly and has an extremely long lifespan. Under natural conditions, it takes more than twenty years from planting to bearing ginkgo fruit, and only after forty years can it bear fruit in large quantities. Therefore it is also called the "grandfather-grandson tree," with the meaning of "the grandfather plants it and the grandson gets to eat," and it is the elder longevity star among trees, called "white fruit" in ancient times. The ginkgo tree has ornamental, economic, and medicinal value. The ginkgo tree is the oldest gymnosperm left over after the Quaternary glaciation movement, and is one of the most precious tree species in the world, so it is regarded as a "living fossil" in the plant kingdom.

Ginkgo tree price list: the ginkgo tree is a living fossil in the plant kingdom. What is its growing environment like? Ginkgo is a rare relict tree species from the Mesozoic, native to China, with wild-state trees only in the Tianmu Mountains of Zhejiang, China. It grows in natural forests at 500-1000 m elevation in well-drained areas, often mixed with needleleaf and broadleaf species such as Japanese cedar, torreya, and tupelo, and grows vigorously. Ginkgo is a sun-loving tree, likes appropriately moist and well-drained deep loam, and is suitable for growing in subtropical monsoon areas with relatively favorable water and heat conditions.

The ginkgo tree is a living fossil in the plant kingdom. Let us learn about its history. Ginkgo first appeared in the Carboniferous Period 345 million years ago. It was once widely distributed in Europe, Asia, and the Americas in the Northern Hemisphere. In the Mesozoic Jurassic, ginkgo was widely distributed in the Northern Hemisphere, and it began to decline in the late Cretaceous.

500,000 years ago, it became extinct in most of Europe, North America, and Asia, and only China's populations survived. Most ginkgo distribution belongs to artificially cultivated areas, mainly cultivated in large quantities in China, France, and the US state of South Carolina. There is no doubt that ginkgo abroad was all introduced directly or indirectly from China.

The ecological benefits of ginkgo are mainly reflected in the fact that ginkgo is both a fruit tree —— nut tree and also a timber tree species, shelter tree species, pest- and disease-resistant tree species, long-lived tree species, and pollution-tolerant tree species. Ginkgo has strong adaptability and is an ideal tree species for fast-growing high-yield forests, farmland shelterbelts, roadside protection forests, bank protection forests, beach protection forests, village protection forests, agroforestry intercropping, and "four-side" greening. Ginkgo resists pests and diseases and is generally recognized as a pollution-free tree, and is the most ideal tree species for ornamental greening. The greening effect of ginkgo trees is very good, though it shows rather slowly; small trees need to be planted for 2 years before they have a good effect, and after large trees are planted, they need 3~5 years of recovery time before they can display their beautiful function.

How much does such an ancient ginkgo tree cost? The price of a ginkgo tree should be considered from many aspects, such as the size of the plant and the quality of the ginkgo sapling. Generally, the price list for young ginkgo saplings is about several tens of yuan each, while the price of a mature ginkgo tree can be several thousand yuan. The editor has made a ginkgo tree price list for you, hoping it helps with your choice.
