Passion flower 1 pruning and shaping method, traction treatment
When the passion fruit grows to 50 cm, it is necessary to establish a bracket in time and pull out the young branches and vines on the shelf to avoid lodging and affecting the appearance. Then, when the passion fruit grows to 70 cm, it is necessary to pull out the side vines on the shelf and cut off the redundant side branches below the main vines. After that, it needs to be pulled several times according to the growth situation to form a double-layer vine plant type.
2. Refinement treatment
Because passion fruit has strong germination ability, proper thinning treatment should be carried out in the peak season to reduce the useless consumption of nutrients. You can cut off some densely growing stems and vines, and also cut off the dense branches, inner branches and shade branches in the middle to promote the concentration of nutrients and help the growth of roots.
Step 3 prune before flowering
Pruning before flowering is an important condition for passion fruit pruning and shaping. At this time, light pruning is the main way, which is to shorten the long stems and vines to about 5 ~ 10 cm and cut off the upper stems and vines. At the same time, cut off some branches that affect the appearance in combination with modeling to reduce the useless consumption of nutrients.
4. Pruning after fruit
Passion fruit should be pruned properly every time it is harvested, but it should not be pruned again during the dormant period. When the stems and vines are full of scaffolds, the internal leaves and aging branches should be cut off in time to shorten the drooping branches by about 15 cm, and the pests and diseases branches and old branches can be pruned again to stimulate the formation of new shoots.
