Stump bonsai cultivated by elm is deeply loved by people for its vigorous and simple trunk and exquisite branches and leaves. Elm is a deciduous tree of Ulmaceae. It is widely distributed in China, especially in the south of the Yangtze River. It can be described as "where there is a village, there is an elm tree". There is wild distribution in Liaoning mountainous area, and family cultivation is also very common. Elm leaves alternate, oval, sharp at the apex, 3-6 cm long and 65,438+0-3 cm wide, with neat obtuse serrations at the edges, straight bark, soft gray shoots and wide extension. The flowers are yellow and green, and the samara is round like a coin. The leaves, branches and stems of elm have certain ornamental value. Its leaves are thin and dense, thick and hard, the fresh bark of the new leaves is irregular like scales, and the lovely spotted branches are soft and drooping, fluttering in the wind. Even though the branches of willows are half decayed or riddled with holes, they are still strong and upright and live forever. It is precisely because of these characteristics that it is vigorous and simple when used as a bonsai, and it has been highly appreciated by the framing industry. Choose elm as bonsai, it is best to dig old stumps on the mountain, cultivate them on the ground first, and then transplant them into pots. It can also be cultivated into small bonsai by high pressure method. Elm is a very common tree species, and Yuan can be seen everywhere. Stump can be dug on the mountain in winter. Note that the base is Catherine-shaped, or the fracture is deformed, there is a hole in the stem, and there is a tumor stump in the cross section of the branch.
