FS003 Passion Fruit Seed (100 seeds/bag)

· Passion fruit seeds, with 100 seeds in each pack. The seeds are dark brown, approximately oval - shaped, with a smooth and shiny surface. Passion fruit, whose scientific name is Passiflora edulis, is a perennial evergreen vine. The plants grown from these seeds have strong climbing ability and can quickly cover supports such as pergolas. Passion fruit is rich in various vitamins needed by the human body, such as vitamin C and vitamin E, as well as minerals like calcium, iron, and phosphorus. It also contains unique aromatic substances, with a rich and distinctive flavor. The fruit can be eaten fresh to taste its sweet - sour and juicy texture, or squeezed into juice to add rich layers to beverages. It can also be used to make desserts, such as passion fruit cakes and passion fruit puddings, and is deeply loved by the public.

1. Soil preparation: Select loose, fertile, and well - drained soil with a pH value between 5.5 - 7.5. Mix leaf mold, peat soil, and perlite in a ratio of 3:2:1 evenly and put it into a seed - raising pot or planting area. Before filling the soil, lay a layer of ceramsite or broken tiles at the bottom to enhance drainage performance. Then water it thoroughly to keep the soil in a moist but not waterlogged state.

2. Seed pre - treatment: Put the passion fruit seeds into warm water at 30 - 40℃ and soak them for 24 - 48 hours. Change the water every 6 - 8 hours during the soaking period to ensure clean water quality and promote the seeds to fully absorb water and swell, improving the germination rate. After soaking, take out the seeds, wrap them with a wet gauze, and place them in a warm (25 - 30℃), well - ventilated place for germination. Rinse them with clean water once a day. After about 2 - 3 days, when some seeds show white, they can be sown.

3. Sowing operation: Evenly sow the seeds on the surface of the prepared soil. Keep the seed spacing at 1 - 2 cm to prevent overcrowding that affects growth. After sowing, cover a thin layer of soil 0.5 - 1 cm thick and gently compact it to make the seeds closely adhere to the soil.

4. Moisture and light preservation: After sowing, use a sprayer to gently spray water to keep the soil moist. Cover a layer of plastic film or transparent plastic wrap on the seed - raising pot or planting area to maintain humidity and temperature. Place it in a brightly lit place but avoid direct sunlight. The suitable germination temperature is 20 - 30℃. Open the film for ventilation for 1 - 2 hours every day to prevent the seeds from mildewing due to excessive humidity.

5. Management after emergence: Generally, the seeds begin to emerge 7 - 10 days after sowing. After emergence, remove the covering in time and gradually increase the light duration, but avoid direct strong light to prevent burning the seedlings. Keep the soil moist, following the principle of "watering when the soil is dry". That is, water when the soil surface is dry 2 - 3 cm, and water thoroughly each time. When the seedlings have 2 - 3 true leaves, thin out the seedlings, remove the weak and over - dense seedlings, and keep the strong seedlings. When the seedlings have 4 - 5 true leaves, they can be transplanted into flowerpots or planting areas. Try to transplant with soil clumps to protect the roots of the seedlings.

a. Temperature control: The germination of passion fruit seeds and the growth of seedlings have high requirements for temperature. If the temperature is lower than 15℃, the seeds germinate slowly or even stagnate; if it is higher than 35℃, the seedlings are prone to spindly growth and reduced resistance. When sowing in winter or early spring, take heat - preservation measures, such as using a greenhouse, covering with plastic film; in high - temperature summer, carry out shading and cooling, and a sun - shading net can be set up to avoid the inappropriate temperature from affecting seed germination and seedling growth.

b. Light adjustment: Passion fruit seedlings need sufficient light for photosynthesis, but in the initial stage of germination and the seedling stage, too strong direct light will damage the seedlings. After emergence, gradually increase the light duration and intensity. During the high - temperature period in summer, especially from 11 a.m. to 3 p.m., appropriate shading is required to avoid direct strong light. As the plant grows, the light intensity can be gradually increased to promote the robust growth and flower bud differentiation of the plant.

c. Water management: From sowing to emergence, keep the soil moist but not waterlogged. Waterlogging is likely to cause seed rot. After emergence, water the plants reasonably according to the dry - wet condition of the soil. Avoid over - watering, which may cause root hypoxia and rot, and also prevent the soil from being too dry, which will affect the growth of the plants. Generally, water when the soil surface is dry 2 - 3 cm, and water thoroughly to avoid watering "half - water".

d. Fertilization points: In the initial stage of passion fruit seedling growth, apply a small amount of thin nitrogen fertilizer appropriately to promote the growth of stems and leaves. When the plant enters the vigorous growth period, increase the application amount of phosphorus - potassium fertilizer. For example, spray a 0.2% - 0.3% potassium dihydrogen phosphate solution every 10 - 15 days to promote flower bud differentiation and fruit development. Fertilization should follow the principle of "applying thin fertilizers frequently" to avoid burning the roots with concentrated fertilizers.

e. Pest and disease control: Common pests and diseases of passion fruit include root rot, anthracnose, aphids, fruit flies, etc. Keep the planting environment well - ventilated, regularly clean up diseased leaves and fruits, and reduce the breeding environment of pests and diseases. Regularly check the plants. Once pests and diseases are found, take control measures in a timely manner. For root rot, improve the soil drainage conditions and use fungicides such as carbendazim for root irrigation; for anthracnose, use fungicides such as thiophanate - methyl and chlorothalonil for spray control; for aphids and fruit flies, use insecticides such as imidacloprid and beta - cyfluthrin for control, and at the same time, hang yellow boards and sugar - vinegar liquid to trap adult fruit flies.
