Will the watermelon seed grow to watermelons?

[Ban my account ffs!]

If you plant it in warm conditions in a sunny area with ample water and a well drained, but moist, nutrient rich soil... watermelons are water intensive and love heat.  In northern Minnesota, even the cold tolerant varieties usually only get to the size of a grapefruit.  The small amount of flesh is absolutely delicious but it’s not worth the effort.
