I decided to plant some watermelons in my garden this year. Its been a couple years since I tried to grow them. I started to pick them last night. I grow 4 varieties: Sugar baby, crimson sweet, lemon crush, and Carolina cross. The Carolina cross a very large and take around 100 day to get ripe. I picked my first "test" melon last night to see if they are ripe. I weighted it and it weighted 51.5 pounds. I think I also have three more that are larger then this one.
