What are the key points for spring management of passion fruit? A full analysis of the latest methods
Spring is the season when all things revive, and it is also the opening chapter of passion fruit management, basic yet very crucial. Good spring management can reduce the pressure of pests and diseases during the passion fruit growing period, increase yield and quality, and play a vital role in overall returns. Now let's follow the editor and take a look at the spring management measures for passion fruit.
1. Pruning and orchard cleaning
The focus is to remove dead branches, diseased leaves, diseased fruits, fallen leaves and weeds, etc. For those with more retained seedlings and frost damage, handle them according to the specific situation. If the main vine is frostbitten, it can be directly destroyed, and replant after the temperature stabilizes. Spring pruning must be done after fruit harvest and before budding. Generally, keep 4-6 primary vines on the main vine, and cut each primary vine back to 20-30 cm. After pruning, take the residues out of the orchard and burn them in time to reduce the pathogen base. At the same time, spray the cut openings and branches for disinfection. Choose to spray disinfectant on a sunny day, preferably lime sulfur mixture.
2. Planting new seedlings
When the spring temperature stabilizes above 10 degrees, consider planting. In old orchards, it is recommended not to plant in old holes, to reduce the possibility of stem rot. After planting, water thoroughly to set the roots, or drench with a biostimulant to activate the root system. Do not rush to fertilize, or it will burn the roots. About half a month after the seedlings are planted, when the root system begins to establish, you can drench once with Sea Elf to promote root growth. After new leaves grow, then consider topdressing.

Because there is more rain in spring, in order to avoid waterlogging and root suffocation, after planting new seedlings, do a good job of clearing drainage ditches to keep good drainage in the orchard. After new leaves grow on the new seedlings, apply a high-nitrogen fertilizer once every half month. After each fertilization, water in time. Be careful to apply less potassium fertilizer to avoid stunted seedlings. When fertilizing, pay attention to the distance from the root system to avoid concentrated fertilizer burning the roots. Half a month before flowering, control the application of nitrogen fertilizer, and topdress with phosphorus and potassium fertilizer. At the same time, maintain medium and trace elements such as boron, magnesium and zinc to promote flowering and fruit setting.
4. Pruning new seedlings
Pruning new seedlings mainly includes bud removal, trellising and topping. If large seedlings are planted, bamboo poles can be inserted and branches tied at planting time so they quickly climb onto the trellis. After the main vine is on the trellis, begin topping to encourage primary vines to sprout. When the primary vines grow to 8-10 leaves, top them again to encourage secondary vines to become fruiting branches.
