Cultivation methods and matters needing attention of cotinus coggygria bonsai

If many people have never seen Bo Huang, it is estimated that everyone has heard of "Red Leaves in Xiangshan", that's right! The main tree species of red leaves in Xiangshan is cotinus coggygria. Cotinus coggygria is green in spring, dark green in summer, golden in early autumn and purple in late autumn. The mountains and plains are very beautiful. At present, few people in the market plant cotinus coggygria as a stump bonsai. These big bonsai piles in the market are basically dug from the mountains, and the process of transplanting is very complicated, so they can't live with a little carelessness. There are also many new varieties derived from cotinus coggygria. At present, the products we know are: Cotinus coggygria, Cotinus coggygria and so on.

The following are the operation steps of transplanting the old pile of Cotinus coggygria after I have been engaged in the garden industry for so many years, hoping to have reference significance for parents who want to play with the bonsai of Cotinus coggygria.

1. Because cotinus coggygria leaves in winter, the trees go into dormancy. As long as the branches are artificially broken, bleeding will occur, which will seriously kill the trees. Therefore, cotinus coggygria cannot be transplanted in autumn and winter.

2. Roots

According to my years of experience, the best transplanting time is 7 days before germination and 15 days after germination in spring.

3. Cotinus coggygria seedlings have dense roots, but there are not many capillary roots. When transplanting, you must use rooting agent to stir and pull mud for planting.

4. If the seedling is too big, the root system is too thick, and the root system is more than 3 cm, it should be sawed flat with a hand knife, and then the root system should be smeared with rooting agent mud.

5. Before transplanting the seedlings, the aboveground parts should be pruned vigorously. The harder you prune, the easier it is to survive after transplanting. All trimmed wounds should be coated with wound daubing agent to prevent bacterial infection.

6. When transplanting big seedlings or old piles, don't go directly to the basin. First of all, choose an oversized flowerpot or a flat land with the leeward facing the sun.

According to the size of the root, dig a square hole 50 cm deep.

7. After the pit is dug, lay 5 cm of fine sand at the bottom. Then add the trimmed cotinus coggygria. The gaps between the surrounding tree roots are all filled with fine sand.

8. Immediately after filling, pour the water thoroughly, and always keep the surface of fine sand moist.

9. Summer maintenance should pay special attention to prevent the harm of powdery mildew and red spider.

10. After a year of careful maintenance, it can be potted.
