Answer: Watermelons need full sun, warm temperatures, rich soil and adequate moisture to grow well. If any one of these is missing, the plants may sulk. You might try fertilizing according to the label instructions if you haven't already done so and be sure to water it if it doesn't rain. If your plant is in the ground, it will need an inch or more a week along with a few inches of organic mulch; if it is in a pot, it may need watering every day. Good luck with your watermelon!
