Key Pruning Points for Passion Fruit at Different Growth Stages
Pruning is important for many crops. It affects the yield and quality of the crops later on. Take passion fruit as an example. The purpose of pruning is to increase light penetration and ventilation, allowing new branches to grow more rationally. However, excessive pruning can also lead to the death of passion fruit. Let's learn about the key points for pruning passion fruit.
Pruning Points
When the main vine of the one-year-old plant reaches the wire mesh of the scaffold, leave two main branches to grow along the horizontal wire, with the main branches producing fruiting branches that hang down. Generally, the branches close to the trunk will fill with fruit first. After the fruit on these branches are mature and harvested, they can be pruned to two or three sections immediately. After the last batch of fruit is harvested in winter, all fruiting branches can be pruned from the base. It should be noted to avoid excessive pruning of passion fruit. There is no need to make significant cuts every year. Excessive pruning will only lead to the withering of the main vine of the passion fruit, and in severe cases, it can directly cause the entire plant to die.
Seedling Pruning
After the passion fruit seedlings are planted and survive, stakes should be inserted to guide the main vines onto the trellis. Generally, one or two main vines are left on the shelf, and many lateral branches are cut. When the main vine grows to one meter high, the top bud can be cut off to allow the lateral vines to grow, leaving two lateral vines on each side. When the lateral vines grow to two meters long, the top of the lateral vines can be cut off.
Fruiting Stage Pruning
After the passion fruit is harvested in batches, cut three to four sections of each lateral vine to promote regeneration of the lateral vines. In summer, pay attention to thinning dense branches, with the branches hanging down to the ground film and pruning them 20-30 centimeters away from the ground.
Winter Pruning
Winter pruning of passion fruit is generally carried out after the last batch of fruit is mature, focusing on the main branch with one side about 50 centimeters. The tendrils on the shelf must be cut off. Fruit branches, diseased branches, old branches, and weak branches should be pruned in a timely manner. After pruning the garden, remember to reinforce the trellis.
The above is a comprehensive explanation of the key pruning points for passion fruit at different growth stages, hoping it can help you.
