1. Prepare the seeds
Soak the seeds in warm water. Soaking time is about 2-3 hours. (Purpose: help seeds germinate quickly and have a high germination rate)
After that, remove the seeds and wipe off the slime. Use a damp cloth to wrap the seeds. Place it in a sunny spot and water it regularly to keep it moist. If favorable, after about 2-3 days, the seeds will germinate..
2. Planting seedlings
When the seeds germinate, you plant them directly in the pot, but for better germination, you put them in small nursery pots.
About 7-10 days later, the seeds will develop into seedlings with 2-3 leaves. You will move plants from potting soil to large pots
3. Care for
Watermelon is a plant that loves water. Water your plants at least twice a day, in the early morning and late afternoon.Keep in mind that if there is too much standing water, the plant will not grow as much.
Also, you may use rice water for irrigation to improve the soil's nutrient content.
4. Make a trellis for watermelon
About a month after planting the plant, you should consider making a trellis for it
You can use existing bamboo, wooden, or plastic rods to form fixed, criss-cross frames. Next, use a string to tie the trunk to the trellis.
5. Harvest watermelons
You may harvest as intended after around 80–90 days of planting. Or after flowering for 30–40 days, the fruit will ripen and can be harvested. Harvest time lasts for a few weeks, but it might be prolonged in good weather.
