First, the four pruning points of pedicel begonia flower 1, plastic pruning
After transplanting 1 ~ 2-year-old seedlings into pots, redundant tillers and tender branches should be cut off, and then 4 ~ 5 branches with strong light should be selected as the trunk. Before germination in early spring, the branches on the trunk should be pruned properly, and the principle of less strong branches and more weak branches should be followed, so that the whole plant can form a loose crown with a sense of space.
2. Main branch buds
After a year or two of cultivation, the trunk of the plant has been formed. Before the plants germinate in early spring, it is necessary to properly comb the bud points of the main branches, leave 2 ~ 3 strong bud points in all directions of the main branches, and erase other weak buds and staggered buds to make the main branches more robust.
3. Shortcuts and heart selection
During plant growth, some long branches will appear, so it is necessary to shorten the length of long branches from 1/2 to 1/3. When the flower height of Malus longipedunculata grows to 50 ~ 60 cm, it is necessary to remove the heart in time to control the plant height.
4, timely thinning
When the flowering plants of Malus mosaic have dense branches, weak branches and dead branches, they should be thinned and maintained in time to keep the crown ventilated. After cutting off these useless branches, it can also save nutrients to a great extent and promote the growth and flowering of plants. The pruning map of begonia is very simple and rarely maintained in the later period.
Second, the maintenance skills of pedicled begonia flowers 1, the soil is acidic.
Begonia sessilifolia is suitable for growing in fertile, loose and humus-rich soil, and must have good drainage and air permeability. The PH value of soil must be slightly acidic. If the soil is weakly alkaline, plants will grow poorly, wither and die. When watering, you can add appropriate amount of ferrous sulfate to improve it.
Step 2 water properly
Watering begonia longipedunculata should follow the principle of seeing dry and seeing wet, keep the soil slightly wet, and accumulate water and rot roots in the seedling pot. Generally, water is poured once every 3 to 4 days in spring and autumn; Water every 1 ~ 2 days in summer; Once a week in winter. When cultivating outdoors, drainage must be done in time after rain.
Step 3: Proper lighting
Pediceless begonia likes light, so it is best to keep it in an environment with sufficient light and good ventilation, but it should be shielded from strong light in summer to avoid burning the leaves of the plant. In winter, it is best to put begonia in a sunny place indoors for the winter.
4. Rational fertilization
During the growth of sessile begonia, thin fertilizer water can be applied once every half month, and the fertilizer is mainly nitrogen, phosphorus and potassium compound fertilizer. Before flowering, the most important thing is phosphorus and potassium fertilizer to promote flower bud differentiation of sessile begonia and improve the quality and quantity of flowering.
Conclusion: After reading the above contents, I believe everyone should know how to prune begonia. Pruning can not only make plants more beautiful, but also promote their growth and flowering.
