Step 1: Incubate the seeds
- Soak the seeds in clean cold water (or lukewarm water around 30°C) for 1-2 days.
- Soak until the seeds appear larger and the shells become softer. Then remove the seeds, discard the small ones, and rinse them thoroughly multiple times to remove any sour smell or sticky residue on the seeds.
- Ensure that the soil is loose, fertile, and free from diseases. You can mix the soil with agricultural additives such as straw, compost, rice husk, coconut fiber, or bean husks that have been treated with microbial products to enhance soil fertility and improve the nourishment of yellow watermelon seeds
- Pour soil into the nursery tray and spread it evenly to ensure the soil is compacted. Spray a little water to moisten the soil.
- Use your finger to make a hole in the tray, about 1-2 cm deep.
- Place the germinated lemon seeds in the hole and gently cover with a layer of soil or fine organic fertilizer.
- Water the nursery tray gently, ensuring the entire tray is moist.
- Punch drainage holes in the bottom of the tray to allow good drainage. Place the nursery tray in a place with enough light to stimulate germination.
- Keep the plants well-hydrated by regularly watering them. It is recommended to water 2-3 times a week, preferably after 5 PM to avoid affecting the newly sprouted Watermelon shoots. Use mulch such as straw, compost, or coconut coir to retain moisture.
- Can be harvested after 1.5 - 2 months when the pumpkin is ripe and reaches a certain size.
