Detailed Guide to the Production Techniques and Cultivation Methods of Caragana Bonsai
Caragana gets its name because its golden-yellow flowers resemble a sparrow about to spread its wings in flight. It also has other aliases such as peashrub, Feilai Feng, Qun Que, and Baopi Bian, and is a deciduous small shrub in the genus Caragana of the Fabaceae family. The plant is about 1.5 m tall, with an iron-black-brown trunk that grows upright in clusters, slender small branches that are yellow-brown or gray, and long branches that droop as they grow; the stems have prickles and the bark peels off in thread-like strips. The odd-pinnate compound leaves bear tiny leaflets that are leathery and dark green. One to two flowers are borne in the leaf axils; they are papilionaceous, yellow with a red blush, and bloom from April to June.
Caragana is distributed on sunny slopes in the hilly and mountainous areas of China's Yangtze River basin and North China region, and is now widely cultivated as a garden ornamental. The roots of Caragana are gnarled and vigorous, the trunk is steely and sturdy, and the supple branches are easy to twist and wire, making it suitable for creating different forms of bonsai such as wind-swept style, cascade style, forest style, raised-root style, connected-root style, rock-clinging style, curved-trunk style, slanting-trunk style, and double-trunk style. When creating them, the form should be made according to the material, using both wiring and pruning, combined with methods such as pulling to carry out comprehensive shaping, so that the finished bonsai is both aged and archaic and lush and full of vitality, achieving an artistic realm that originates from nature yet surpasses nature. Before Caragana bonsai is placed in a fine pot, the stump can first be grown in a clay tile pot filled with clean plain sandy soil; after it survives, following preliminary shaping and root raising, it can be moved into a fine pot for viewing in the second or third year. Potting and transplanting of Caragana should be carried out before bud break in spring. Before planting, excess branches should be cut off, and torn or injured roots should be removed, with the cut surfaces required to be smooth. Soaking in water is strictly prohibited, otherwise the plant will inevitably rot at the roots and die after planting. After planting, water once to settle the roots, and thereafter do not water until the soil is dry. Plants that have not yet unfurled leaves should be placed in a wind-sheltered, sunny spot for care after potting; the ambient temperature need not be too high, so that they first grow roots and then leaves, avoiding premature sprouting due to excessively high temperature, which causes the "false survival" phenomenon.
Caragana cultivation commonly uses methods such as sowing, division, cuttings, and layering. It prefers a sunny environment and tolerates drought and poor soil, but fears waterlogged and overly shady conditions. Its sprouting ability is very strong and it grows rapidly, so during the growing season it should be pinched back frequently, which not only keeps the leaves small but also encourages more buds and more flowers. At any time, cut off branches that are too long, too messy, or otherwise affect the bonsai's appearance. Each spring before bud break, heavily prune the plant once, cutting away weak branches, leggy branches, dead branches, and other branches that affect the shape. Caragana is not afraid of sun, and even in midsummer it does not need shading. However, too much water will rot the roots, and too much fertilizer will make the leaves too large and reduce the ornamental effect, so in general no additional fertilizing is needed during care; however, when flower buds form, spray the leaves once with 0.2% monopotassium phosphate to extend the flowering period. In winter, overwinter it indoors in a cool place or outdoors in a wind-sheltered, sunny place. About every 3 years, before bud break in spring, repot once; the potting soil should be a moderately fertile, well-drained sandy soil.

How to Care for Caragana Flower Bonsai
Caragana, also known as Caragana flower and peashrub, is mainly distributed in East China, Southwest China, and other regions of China. It is a deciduous shrub in the Fabaceae family, with angular branchlets and four small leathery leaflets with a glossy surface; its roots can coil and are easy to shape. It blooms in spring, with golden-yellow flowers. It can be propagated by layering and cuttings.
Caragana is small in tree form, with a straight, slender stem and bark of an antique iron color. A single-trunk plant can be wired and pruned into many forms such as slanting-trunk style, curved-trunk style, lying-trunk style, weeping-branch style, and cascade style, and the roots can also replace the trunk. Caragana should be collected during the dormant period and the plum rain season. When collecting, first cut off most of the aboveground stems, keep a small number of well-formed short stems, then carefully dig out the main root; roots with curves and coils are better. After collection, coil and shape the roots, shape the stems according to a suitable production form, and after pruning, pot them. First plant them in a clay pot with soil for care; the roots must not be exposed too much, and the soil is required to be loose, breathable, and well drained. Pay attention to caring for the roots and avoid water accumulation that damages the roots. Newly potted plants should be kept moist and placed in a shady place, then repotted year by year, with root raising and root exposure carried out.
After Caragana is potted and sends out branches, fertilize and water as appropriate, applying frequent light fertilizer and strengthening management. If many stems grow in clusters, they can be thinned out. Pinch back promptly to promote branching and shaping.
Caragana is a sun-loving flowering plant. During the growing period it needs sufficient light, and fertilizer and water should not be excessive, otherwise the branches and leaves will grow leggy and the internodes will become longer. When branches and leaves are too dense, they can be removed by hand. After flowering each year, prune and thin the branches. When pruning, pay attention to the growth direction of new buds, keep 2 to 3 buds per branch, and cut off crossing branches, leggy branches, and diseased or weak branches.
The branches and trunks are susceptible to damage by wood-boring insects. The common wood-boring beetles feed on the phloem and xylem of the trunk and branches, so pesticide spraying should be carried out regularly for control. Frequently check whether there is insect frass on the soil surface of the pot. If frass is found, follow the direction in which the frass falls and search upward for the insect hole. A thin iron wire can be used to pierce along the insect hole to kill the pest, or a syringe can be used to inject a 1000-fold dilution of 80% dichlorvos into the hole, and cotton soaked in the pesticide solution can also be used to plug and seal the hole to kill the pest.
