Among them, elm is also an excellent tree material for making bonsai, but some kinds of elm with small leaves have better ornamental effect after making bonsai, such as elm and white elm. Let's share the production of elm bonsai.
First, the time of drawing materials
Elms are widely distributed in China and often grow in the wild. The excavation time should be from March to April in spring, when the survival rate after transplanting is relatively high.
Second, pruning treatment
After digging the stump, trim the branches and roots first, and cut off or truncate the branches and roots that are too messy. Because elm has sticky juice, it is necessary to treat the wound after pruning, otherwise too much juice will affect the survival rate. Wound treatment can be sealed with wax or paint, and if the juice is not much, a layer of erythromycin ointment can be applied.
Third, the basin pile
Elm piles can be planted directly with clean river sand, which is moist, warm and easy to take root. At this time, the wound has not healed, so it is not suitable to use too fertile soil. After planting in the upper pot, soil should be cultivated on time to keep the pot soil slightly moist. Keep it in a ventilated and light-transmitting place for maintenance, and you can spray water on the trunk every day to increase the humidity of the environment.
Fourth, the late modeling
For elm modeling, we can make it into different forms of bonsai modeling by pruning, rolling and other methods according to the natural shape and material potential of the stump. The overall effect is dense and orderly, harmonious and natural.
V. Maintenance of Elm Bonsai
1, water
Elm is drought-resistant and afraid of waterlogging, so it can't accumulate water in the basin at ordinary times. Too much watering can easily lead to root rot. Keep the basin soil slightly moist during the growth period. If the pot soil is too wet for a long time and the fertilization concentration is too high in hot summer, it is easy to cause root rot and even the whole plant wither. In hot and dry weather, you can often spray water on the leaves of plants to humidify the environment.
2. _ Nutrients
Elm bonsai does not need to be fertilized too often, but it is easy to make the branches and leaves flourish and the leaves are too large because of too much nutrition. At this time, it is necessary to properly control water and fertilizer to inhibit its growth. In order to make the elm pile grow thick, more organic fertilizer should be applied during the growing period, and thin organic fertilizer or cake fertilizer can be applied once a month. You can also apply more nitrogen, phosphorus and potassium compound fertilizer, which can accelerate the growth of plants and make them take shape quickly.
3. Lighting equipment
Elms like sunshine and thrive in sunny conditions. In an environment lacking sunshine for a long time, plants will grow slowly, with thin branches and slender leaves, thus affecting the ornamental effect. When maintaining at ordinary times, put the bonsai in a sunny place and let it fully carry out photosynthesis, so that the leaves can be green and beautiful. Summer is the period when elm roots grow. Appropriate lighting will promote its vigorous growth, promote the growth of piles and roots, and increase the molding speed of bonsai.
prune
During the growth of plants, branches and leaves should be trimmed to maintain a good tree shape. Pruning in the growth period is mainly about pruning long branches and messy branches. In the later period, the remaining branches can be shaped to keep the whole tree dense and tidy and increase the ornamental value.
For elm trees with large leaves, in order to make the leaves grow smaller and enhance the appreciation. During the growing period, elm leaves can be picked. In this way, elm leaves become smaller. Picking leaves can be done in early and middle August. All the leaves of elm fall off, leaving only a small amount for photosynthesis, so that the new leaves will become smaller.
