Ulmus pumila Jinye is one of the few new varieties of color-leafed tree species in the world that can be applied across five temperature zones, and it is also the only new variety of color-leafed tree species in China that has obtained the protection right of new plant varieties from China, the United States and the European Union, thus showing its status. Elm has golden leaves, which are very beautiful and have many garden uses.

First, how to trim the golden elm ball?

Golden elm is very resistant to pruning, and it is also one of the color-leafed seedlings that are very suitable for modeling. There are regular shapes and different shapes in general gardens, as well as animal-like shapes, of course, natural shapes and lively levels. Golden-leaf elm ball looks both normative and lovely, and it is a popular one in modeling. So what are its modeling methods? First, choose Ulmus pumila. Plants with short plants, dense branches and compact crowns are more suitable for modeling. Single plant modeling is difficult, and the effect of multi-plant co-planting is generally better. During the curing period, the crown should be properly dense and evenly distributed on all sides.

Second, the elm ball pruning method

The pruning method of golden elm, the shape of golden elm is eclectic, mainly including regularity, imagery and nature. Regular modeling pays attention to regular shape, solemn and beautiful appearance, and most of them only need to cut off the upper part of branches by 20 ~ 30 cm, which will be evenly matched with modeling when planting. Image modeling pays attention to vivid images, such as "triumphant" and "Golden Rooster Dawn" are all popular modeling forms. Before planting, plants of corresponding size should be selected according to the morphological requirements. Firstly, the general outline is cultivated, and then the modeling is carried out by combining the methods of winding, drawing, hanging and winding, so that the modeling tree finally presents the desired effect. Generally speaking, the spherical shape of elm is easy to build, but it also needs long-term pruning and maintenance to form.

3. When will the elm be pruned?

1, habit

Elm is cold-resistant and pruning-resistant. Its axils are arranged in clusters, and its samara is nearly round with dense branches. It likes fertile and moist soil and is not resistant to water and humidity. Plants like light, cold and drought. Widely planted in various places, with high greening value and obvious ecological function.

prune

Elms are resistant to pruning, but they can't be pruned all the time. Early spring and summer are good times for pruning. In spring, remove redundant branches, dead branches, drooping branches and insect branches, and increase ventilation and light transmission of the crown, preferably by cutting them short. Remove the green leaves from the branches in summer and prune the weak branches for the second time. Summer is the peak season for growth, and pruning at this time can promote leaf germination and enhance the ornamental effect.

Step 3 maintain

After pruning elm trees, the wound should be properly treated, otherwise the wound will be infected with germs. Generally, after pruning, apply healing agent to the incision to promote wound healing and try not to let the wound get wet in the rain.
