Back to All Watermelon Seeds

Giant watermelons can weigh in at over 45 lbs, with some fruits getting as heavy as 70 lbs. If you are looking for monster sized watermelons, this is the class for you. Note that not all fruits will reach the 45 Lb mark, these are the varieties capable of that size when conditions are right for them.
