We planted Sugar Baby watermelons this year. Seeds for all vines came from the same package. About a week ago, we harvested the first one. Ripe, red and delicious. Yesterday, I harvested another one, and put it in the fridge to cool. We cut it today and it has YELLOW meat, with little tinges of pink around the seeds. This one was harvested 77 days from transplanting, and it was deep yellow on the side touching the ground. The stem had not turned brown, but looked dry and shrunken. The first melon had same indicators of being ripe. But it turned out red. The mystery is I tasted of the yellow melon, and it tastes sweet and ripe, with a very juicy texture.

How can this be? Is the melon ripe, or just short of ripe? Do they turn yellow before they turn red? The seed package says melons should be mature at 70 days. Has anyone else had a Sugar Baby that ended up with yellow meat? And took longer than 77 days from transplant to ripen?
