From Jiangsu nursery base learned that the price of 15CM seedlings in 1500 yuan;18CM seedlings in 1800 yuan;22CM seedlings in 2500 yuan;30CM seedlings in 5500 yuan. Celtis sinensis germinates in February in spring, leaves in October in autumn, florescence in March, seeds mature in August and September, and the evergreen period of the whole year is 210~240 days.

When is the tree planted?

In autumn and winter, the growth and metabolism of the aboveground and underground parts of the tree body are weak or stopped, and the survival rate is the highest. The influence of planting and transplanting on the tree is the least, and the management is relatively easy.

How to grow trees?

1. The seedling cultivation of Celtis sinensis is mainly obtained by sowing. It can be sown from January to May in South China and East China. It is suggested to sow directly in the field and plant in rows. 8~10 jin of seeds per mu of Celtis chinensis. The soil should be fertile and breathable, which is conducive to drainage irrigation. Saline-alkali soil cannot be planted. First of all, the seeds are soaked in water for 2 days, then taken out and dried, sown, the row spacing is 40 cm, about 10 days to start germination, 20 days to basically complete the emergence, 35 days for the first time, the best seedling spacing 8~10 cm, about 30,000 seedlings per mu, the year can grow 1~1.3 meters.

2. Park tree likes sun and bears shade. It can grow up in 5 years on fertile land. It can also endure drought and barren land and survive in mild saline-alkali land. The seedlings of that year are very thin, the tree stem shape is poor, and it is not suitable for fixed plant planting. It needs to be planted once and grow for 2 years. The seedlings of the current year are planted separately, and the plant spacing is recommended to be 40×70 cm. After 2 years of planting, they can grow to 2~3 cm and 3~4 meters high. At this time, a tree stem is straight and the beautiful tree seedlings have been cultivated. We can consult us by telephone or teach us on the spot in the future. Pay attention to pruning and shaping in seedling stage, and raise straight and complete trunk. It is recommended that the branch point be between 2.8 and 3 meters.

3. Habits of Park Tree

Park trees are not very strict about land requirements. In addition to low-lying ponding land can not be planted, other land can be planted. Celtis can adapt to different soils, including slightly acidic, slightly alkaline, neutral and calcareous soils. In order to make the cypress grow tall and its branches flourish, it is better to plant it on loose, fertile and well-drained land before planting.

4. Celtis planting technology

(1) The planting of cypress trees is usually based on sowing and breeding. The seeds can be collected at the ripening stage of fruit. After harvest, they should be stacked and ripened. They can be sown in March of the next spring. The loose and fertile soil is the best seedbed, and then covered with soil and grass. About 30 days later, they germinate and emerge. Pay attention to timely intertillage and weeding during the growth period, proper watering and fertilization management, to avoid weeds and trees competing for fertilizer.

(2) Transplantation can be carried out from autumn defoliation to spring germination. Transplantation of big trees should be carried out with soil balls at a ratio of 1/7. Except for small and medium seedlings, soil balls are not required to be transplanted, and roots can be dipped in mud. The depth of soil balls and ground surface can be regarded as planting standards.

5. Daily maintenance of Park trees

(1) Summer temperature is higher every day, evaporation is large, after the new branches survive, in order to make the newly grown tender branches grow well, according to the situation of the tree, in addition to spraying on the branches and leaves, water should be poured once in the morning and evening, keep the soil moist, and water should especially master the principle of watering. However, due to heavy rain due to weather reasons, it is necessary to prevent ponding in time. In winter, do not forget to water, you can choose to water at noon when it is not frozen.

(2) The fertilizer should be higher during the growth period of Celtis sinensis. In order to make the tree grow tall, fertilizer is mainly phosphorus and potassium fertilizer, fertilizer can be applied once every half month, and it is better to apply thin fertilizer frequently; on the ground, a deep pit can be dug beside the seedlings, and then the fertilizer is buried in the middle. To autumn topdressing a decomposed organic fertilizer, the purpose is to lay a good foundation for growth in the coming year.

How to maintain the potted plant?

1, placement environment: because the park tree likes light, should be placed in the park tree bonsai sunny courtyard, balcony, need to place the bonsai indoors, should choose enough light and air circulation window. Because the leaves of plants need sufficient sunlight to carry out photosynthesis, only by giving sufficient light can the leaves of the tree be kept full and lush.

2. Water and fertilizer management: Park trees are resistant to drought, so it is not advisable to water their bonsai heavily. The watering frequency is controlled once a day in spring, once in the morning and once in the evening in summer, and once every five days in winter. It should be noted that watering should be avoided at high temperatures (around 2 p.m.) in summer, because plant transpiration is extremely strong at this time, which will cause a large loss of water and lead to tree wither. As for fertilization, nitrogen or potassium fertilizer can be applied once a year in spring and summer to make the growth of Celtis sinensis more robust and enhance its ornamental value.

3, pruning posture: due to strong growth, we can often prune the Park tree bonsai to achieve satisfactory modeling results. In the process of modeling, coarse pruning method is often used. When the new branches are about 7cm long, most of the leaves are trimmed and buds are picked to maintain the modeling.

4, pest control: pests are often an important factor affecting the healthy growth of hackberry, in order to control pests can be sprayed to hackberry diluted dimethoate or dichlorvos solution. However, attention should be paid to the concentration of pesticides formulated to prevent damage to the vitality of the tree itself.
