Why the watermelon vines became drought?
Why the watermelon vines became drought? During the field watering, we look for vines which are destroyed by disease, but we don't know what's the cause. Please advise me on some plan to remove this problem.
Before you can remove a problem, you have to determine what the problem is. The place to begin is to determine if there is a cultural problem, so let's start with a basic primer of growing healthy watermelons: https://www.gardeningknowhow.com/edible/fruits/watermelon/growing-watermelon.htm
After assessing basic cultural needs, you can turn your attention to the possibility of disease or insect infestation. You need to describe the symptoms, or even better than that, take leaf, vine, root and soil sample to a horticultural professional for analysis. Do you have any agricultural or horticultural services in your area, or university botany department, or botanical garden? Hopefully, by using these methods, you'll be able to learn the source of your difficulty.
