Essential Reading for Passion Fruit Cultivation: A Detailed Explanation of Key Technical and Management Points

SummaryIf the passion fruit seedlings you bought show yellow leaves, they need to be pruned. When planting, you can dig a hole 30cm wide and 20cm deep, then apply farmyard manure. Within 5 days after planting, the seedlings need to be covered with a shade net to protect them from the sun. About 10 days after planting, start watering frequently. Yellow or curled leaves during the seedling stage mean a lack of fertilizer and nutrients, so fertilize frequently, but be careful not to touch the roots. Later, prune the branches and leaves in time and set up a support frame.

I. Essential Reading for Passion Fruit Cultivation

1. Leaf pruning

After receiving the seedlings, take them out immediately, place them in a cool indoor spot and water lightly to keep the seedling leaves moist. If some seedlings show yellow leaves or leaf drop, this is normal. Before planting, most of the leaves need to be cut off, cutting each leaf in half is sufficient; those without yellow leaves do not need pruning.

2. Planting and applying base fertilizer

They can be planted in a pot 30cm in length, width and height, or planted in the ground or in a courtyard. You can dig a hole 30cm wide and 20cm deep, then apply compound fertilizer, or about 2 jin of farmyard manure, then backfill with 15cm of loose soil. Plant in the evening or on a rainy day. Cut off the plastic bag protecting the roots with scissors, being careful not to knock off the soil, then plant the seedling in the soil, water thoroughly, cover with soil and firm it down.

3. Shading and watering

Within 5 days after planting, exposure to the sun will affect the seedling survival rate, so a shade net can be used to block the sun. About 10 days after planting, water frequently; when it rains, there is no need to water.

4. Maturity period

Purple passion fruit seedlings will flower and bear fruit in 3-4 months, while yellow passion fruit seedlings will flower and bear fruit only in 7-8 months. Generally, the yield is relatively small in the first year, and in about May of the second year there will be a large amount of flowering and fruiting, and no manual pollination is needed. Two months after flowering, the fruit enters the maturity period.

5. Fertilizing, pruning and trellising

During the growth of the seedlings, phenomena such as yellow leaves and curled leaves are all caused by a lack of fertilizer and nutrients, so frequent fertilization is needed. When fertilizing, be careful not to scatter it on the roots of the seedlings. When the seedlings grow to 80cm, only 1-2 main stems need to be kept, and all the excess can be cut off. Later, the method of building a support frame is the same as for growing grapes; you can find a bamboo pole and insert it into the soil to guide the seedlings to grow upward.

II. Precautions for Planting Passion Fruit

1. Climate

(1) Passion fruit is a tropical fruit that likes warmth, so it has relatively high temperature requirements. The suitable growing temperature is around 25°C, but as long as the temperature does not drop below 0°C it can still grow normally. If it is below 0°C, passion fruit will suffer severe cold damage, and in severe cases may even be frozen to death.

(2) If there is continuous frost and low-temperature weather, insulation measures need to be taken for passion fruit in time. Passion fruit can be insulated in a greenhouse. Although passion fruit does not have very high requirements for rainfall, planting it in areas with an annual rainfall of about 2000mm and evenly distributed rain is more conducive to its growth and development.

2. Land

(1) Passion fruit has relatively strong adaptability. Although it does not have very high requirements for soil, for large-scale planting the soil layer should be at least 50cm or more, and the soil quality needs to be fertile, well-aerated and well-drained.

(2) If the soil is relatively barren, it cannot provide sufficient nutrients for the fruit trees over a large area, which will cause poor growth and development of passion fruit and affect its quality and yield.

3. Varieties

There are many varieties of passion fruit. The varieties generally planted include Mantianxing and Tainong No. 1, among others, because other varieties, such as Zixiang No. 1, have relatively lower yields in artificial cultivation compared with other varieties and require more time and effort, which has a great impact on the economic benefits of growers. Therefore, high-quality varieties need to be selected for planting.

4. Planting

Although passion fruit has relatively strong adaptability, if you want to plant on a large scale and obtain high quality and high yield, you still need good management and planting techniques. In the later stage, do a good job in pest and disease control, and set up trellises and prune branches and leaves in time.
