A: Watermelon is prone to a kind of fungal disease called blight in the process of growth. The disease is transmitted through the soil, and the residual time of the bacteria in the soil is as long as 3 to 5 years. In the soil where watermelon is planted, a large amount of Fusarium oxysporum often remains. If the next year, the watermelon is particularly susceptible to infection and causes dead seedlings. Therefore, the plot of watermelon is best changed every year. For the land that has been planted with watermelon, it is best to grow grass crops such as rice and corn, or vegetable crops such as potatoes and cabbage, but it is not suitable to grow melon vegetables to reduce the survival rate of Fusarium. If it is really impossible to change crops, seedlings of some cucurbitaceous crops that are more resistant to Fusarium wilt can be used as graftstocks to graft watermelon.
