Key points of tree stump bonsai maintenance in autumn

Tree stump bonsai is a living work of art dominated by woody plants, with large pots and small stakes, and the conservation and management measures are far greater than ordinary grass flowers and general small shrubs. If the management measures are improper, not only can not be cultivated into a pile scene of artistic value, but also will destroy the already successful works of art, and all previous efforts will be wasted.

Early September and autumn is the season when everything begins to wither. The general characteristic of tree growth in autumn is that the spring and summer shoots have been lignified, and a new root and leaf system has been formed, which increases the assimilation area of trees and accumulates nutrients for autumn shoot and flower bud differentiation. The autumn shoot growth and flower bud differentiation of evergreen trees are carried out at the same time, the competition for nutrient distribution is fierce, vegetative growth is better than reproductive growth, reproductive growth consumption is greater than vegetative growth, and can inhibit each other.

If the nutrition accumulation in autumn is not sufficient, the autumn shoot can not be lignified, there will be fewer flowers and fruits in the coming year. The new and old branches that are not lignified must undergo the test of severe winter, and the test of plants in severe winter is more cruel than that of hot heat, so autumn must create conditions for trees to survive the winter, promote their autumn buds to sprout early, prolong their growth time, and speed up their growth. Fully accumulate nutrients to facilitate its smooth winter. In autumn, the stump germinates late, the growth time is shortened, the nutrient accumulation is insufficient, the branchlets are not lignified, the old and weak branches and inner branches do not accumulate enough nutrients, and the overwintering branches are easy to shrink and wither. This is especially true of newly planted piles.

Therefore, the management of tree stump bonsai in autumn is an important period, and soil, fertilizer and light should be strengthened. Evergreen trees should also pick their hearts to promote the Lignification of autumn branches as soon as possible so as to create conditions for overwintering. Conifers and deciduous trees sprout but not sprout in autumn, so it is necessary to promote their dormancy in late autumn so as not to waste nutrients and affect their smooth overwintering.

Key points of maintenance and management in autumn:

1. Lighting

Bonsai trees should strengthen the light in autumn, put the pot in the all-day place and let the sun shine, which is beneficial for the trees to accumulate nutrients, take root and grow leaves, blossom and bear fruit.

2. Basin soil

The soil should be dry and wet alternately and poured thoroughly. Usually loosen the soil, let the air seep in, and increase the air content in the soil. The basin soil is dry and wet alternately, when the soil is dry, there is little moisture in the soil, the air can penetrate into the space filled with water, and the root breathes smoothly. Proper drying can promote the growth of roots, facilitate the development of autumn shoots, and form leaflets.

3. Fertilization

Fertilizer should be timely and appropriate, light application should be applied many times in early autumn, less fertilizer should be applied in Mid-Autumn Festival, fertilization should be controlled in late autumn, and it is appropriate not to promote late autumn shoots. This use of fertilizer can promote early growth of autumn shoots, so that vegetative growth and reproductive growth are carried out at the same time, and there will be many leaves and flowers and fruits in the coming year. If the tree is in good condition and there is more autumn fertilizer, spring flowers may bloom in autumn. My black persimmon and Luohansong have spring flowers and autumn blossoms and autumn fruits for many times. Early application of autumn fertilizer is widely used in fruit production, and the management of bonsai stump is fine, so autumn fertilizer should be applied early.

4. Pruning

During the period of tree growth, the top advantage is obvious. Under the condition of good phosgene, the growth is exuberant, the shape proportion of the stump is deformed and expanded in the autumn shoot growth, and the leaves are concentrated to the edge. The distribution of nutrients is also uneven, and the supply of nutrients on the old branches and central branches is insufficient, which is intended to die in winter. Autumn shoot and spring will also sprout at the top, become bigger, lose the center of gravity, break the composition proportion of the stump, and become not very beautiful. Therefore, before the formation and growth of autumn buds, thinning and shearing should be carried out, and the coring of autumn shoots should be removed after the growth of autumn shoots, so as to overcome the top advantage, restrain and combine, distribute nutrients reasonably and maintain a good growth trend.
