Excavation can be carried out in late autumn and early winter, before the leaves begin to freeze, or after thawing in the following year, before the leaves are displayed. After the stump comes out of the pit, it should be roughly trimmed, dipped in mud, wrapped in plastic bags with wet straw or wheat straw, and transported back quickly.
Due to the clumping characteristics of goldfinch, its modeling should first consider jungle style, multi-dry or double-dry, and try to keep elegant dry branches. Because the goldfinch is easy to move down to the germination point, the germination is not in place, so the kerf stays at the expected germination point 1CM-2CM and is sealed with paint or wax. Goldfinch's roots are soft, so try to keep them long when digging, especially the tiny roots, in order to make up for the base. Its soft and slender roots can be tightly wound together at the base, and can grow into a whole, becoming an artificial raised stump in the future. Thick roots should be cut in place at one time, so as not to affect the pot in the future. The root quality of goldfinch is different from other tree species, with fleshy roots and strong longitudinal fibers. It is difficult to trim evenly, and it is easy to break horizontally and split vertically from the base of one root. Bacteria can easily invade this broken root.
After quick pruning, soak the dug or purchased stumps in clear water for 24 hours, and then plant them in a slightly larger clay pot or wooden box. The culture medium can be pure river sand, the sand is sealed as high as possible, and then gradually recedes after germination. After planting, water, cover the pots and trees with large plastic bags and put them in sunny places to increase the air temperature and temperature, which is beneficial to the survival of stumps. Observe and spray water frequently. Make the air convection, cut it twice every few days until the new branches are lignified, and the plastic bags can be taken out and transferred to normal management. In the first year, new branches can grow in the whole sand, and after lignification, they can be applied thinly and diligently without affecting their growth. In the spring of the following year, after the roots grow vigorously, they can be placed in a pot with loose and fertile soil, which can greatly shorten the molding time.
The new branches of goldfinch are slender, and the new pile will flourish without any sleep in the first year. Wait until the next spring, you can cut off the branches that are useless for modeling, and improve the tree shape by means of coarse binding and fine cutting. The handle of goldfinch is difficult to harden into a needle, so it is more difficult to tie it flat, so it is often cultivated by hanging and pulling. What needs special attention is that the upper branches are sunny, well ventilated and grow rapidly. Inhibit its growth. However, the growth conditions of the lower branches are relatively poor and the growth rate is slow. Therefore, it is necessary to remove the branches that affect the lower growth, keep the lower branches ventilated and transparent, create a good growth environment for the lower branches, and promote their vigorous growth. The top of the horizontally growing lower outer branch can be erected with bamboo poles, and the lower branch will soon become thicker, and then shrink back to its original position after reaching the ideal thickness.

The management of the formed goldfinch bonsai is relatively extensive. After budding, it only needs to be reshaped and cut off dead branches, twigs, dense branches and unsightly branches every year before flowering. After flowering, the residual flowers should be picked in time to avoid pod setting and nutrient consumption. For the branches of the previous year, two or three leaves should be cut off from the base to promote new branches and increase the number of branches. The branches after flowering are 5CM long.
Although goldfinches are barren-tolerant, they also like to fertilize. After the newly planted stumps survive, fertilization can only be carried out after the newly planted branches are lignified. Thin fertilizer should be applied frequently every other week. Nitrogen fertilizer is dominant in spring and summer, followed by phosphorus and potassium fertilizer after beginning of autumn. Combined with root application, potassium dihydrogen phosphate can be sprayed for two or three times. Combined with turning the pot, it is necessary to apply full base fertilizer, and the fertilizer is preferably decomposed sesame cake, soybean meal and bone meal or poultry.
