Charlie and his Grandpap’s special project is the watermelon patch, and Charlie declares they should grow a “wishing watermelon” in the patch. The pair works together to plant the watermelon seeds, which Charlie has been keeping safe in his shirt pocket. They work the seeds into the sandy soil, water it and then take a well-deserved break. Their daily routine then includes a regular check of the growing plants, in between trips to their secret fishing spot and swimming hole and games of basketball and cards. Meanwhile, Grandpap has been trying to guess what Charlie’s wish will be and finally, he and Charlie find the perfect melon, which Charlie picks. Later at the house, he sticks his hand in the middle of the watermelon, pulls out a handful of seeds for planting next year and makes his wish. The story (and the ritual) ends with a juicy bite. Moser works in some nice horticultural details, and Schuett’s radiant pictures, in acrylic and gouache, are as warm and friendly as the story. (Picture book. 4-7)
