Cross pruning method is suitable for varieties with small branch opening angle (branch lifting), such as' Zijin hammer'. When the seedling is higher than 20 cm, it should be cored to promote the germination of new branches. Because the lateral branches are generally symmetrical, when pruning, you should keep the two symmetrical branches above and wipe off all the branches and leaves below. When the lateral branches grow to about 10 cm, they need to be topped. Let the new branches grow after they grow. Pay attention to cut off the inward and downward growing side branches at any time.
After pruning, potted plants with the same length and diameter of 8 to 15 cm- 18 cm will retain 8 to 10 branches. ?
Tower pruning method is suitable for varieties with large opening angle of lateral branches (branches extend horizontally) and vigorous growth, such as' white calyx' and' girl skirt'. Don't top plants when they are small. When it grows to 20 cm, cut off all branches and leaves below 10 cm. After the lateral branches grow, in order to avoid overlapping branches, layered pruning can be used. Leave a symmetrical branch on each layer, remove a pair of symmetrical branches, leave another layer of symmetrical branches, and so on.
Natural pruning method is suitable for varieties with creeping branches and weak growth and varieties with large and double flowers. Trim it into a natural shape according to its shape. When the seedlings grow to 30~40 cm, remove the top of the trunk, remove the adjacent overlapping branches, and shorten the long branches to promote branching. Cut off the inward growing side branches at any time to promote the beautiful shape of the plant.
Upside-down golden bell flower shaping and pruning. In the northern natural environment, the flowering period is from April to July. Therefore, pruning should be stopped in late March in spring to ensure flowering in mid-April. Because the flowers in the upside-down admiralty are at the top, the branches will continue to elongate. When the flower branch grows to a certain length, it is necessary to pick the heart before the new branch can continue to blossom.
Cut off the twigs and leaves in the center of the plant at any time when flowering, so as to avoid consuming nutrients and facilitate ventilation and light transmission.
After flower shaping and pruning, when the temperature rises to 30℃ in July, the plant will enter a semi-dormant state. The leaves will gradually weaken and need to be trimmed again to reduce nutrient consumption, which is conducive to safe summer. Cut off all the longer branches, leaving only the main branches, remove all the old leaves and put them in the shade. If there is bud at this time, it should be pulled out in time. New branches will grow in September, when the plant type will be more compact.
