Umm, if those pictures show the new larger pot, the plant will continue to be in trouble. Much too small afor a plant that can easily become 4 feet across. It's early enough in the season that you might consider seeding new plants, fertilizing regularly as soon as the 2nd set of leaves develop. And it would likely be helpful to become acquainted with your county's Extension Service office which will be able to direct you to local gardening information.

I planted my first watermelon this year with three Sugar Baby transplants. Since it's my first year growing, I've been taking lots of notes and pictures. I documented the first melon on 6/15, about a month after planting and was the size of an almond. It grew surprisingly fast and stopped at 8 inches turning from a striped juvenile to a typical solid deep dark green. Then I started watching the nearest tendril which turned completely brown at about 30 days, but the bottom stayed dark. It was sitting on a piece of wood since it was found and no sign of white or yellow bottom. I've read this thread and others that mention Sugar Babies are tricky. Lots of videos on YouTube of people cutting into their first Sugar Baby, some darn right funny. Especially when they aren't even red, or they look good and they taste them and you can tell they are trying very hard to like it. I was dying to try one, and decided to sacrifice my first born at 41 days on 7/26 despite his dark bottom. Needless to say he was a tasty, crispy little boy with surprisingly very few seeds.

Funny thing - I just logged on to GardenWeb to ask something similar. I have (had?) six melon vines growing well with lots of fruit almost ripe and out of the blue a foliage disease (I believe) spread through them and within 7 days all the leaves where wilted, brown and gone. To my inexperienced amazement the fruit continued to ripen and I have harvested a Noir de Carmes, Collective Farm Woman, Honeyrock and Petit de Rennes. They were of average quality, but passable. I really thought without leaves they couldn't ripen. Maybe one difference is that the leaves are dead but not the vine. The vine still looks normal as far as I can tell.

I planted Sugar Baby Watermelon seeds and they grew really well. However, I will NEVER plant them again. There were way too many seeds! The watermelons are a nice size for singles and small families, but there are as many seeds as a large watermelon.
