Because triploids unfortunately cannot reproduce sexually, they are planted next to diploid plants that produce pollen, making it easy for pollen to be transported to the triploid plant by insects or birds; this process is necessary to see the end result take shape.
When the seedlings emerge, one must water them moderately and not douse them; the soil should be moist but not saturated with water. The required pH of the soil is 7. You will be required to get your planting area ready at least three weeks before it can actually be planted.
The result of improper pollination will give a bad batch of seedless watermelons, that lack texture, flavor. As statistics says, the number of pollinating insects should be 15,000 per acre where these are grown. The presence of honeybees is vital. Every row of diploid pollinators should be followed by two rows of triploid plants for effective pollination.
Any fluctuations in temperature will leave your watermelons struggling against a disease's effects. Therefore, maintaining the aforementioned numbers is vital. Check on the watermelons as often as possible and take care of any disease-related issues as and when they occur.
