Hi, I am having a very irritating issue with watermelons. What's is that all of the young watermelons are shriveling up and discoloring. I have no idea if what is. Also the watermelon has ZERO flowers on it. Any that try to come out just turn black.We also live in dickson, so we have not been getting rain for a month. They are getting watered 15 minutes each morning though. I just really want to grow watermelons! I have no clue what I'm doing wrong! Please help!
