When 8-year-old Jackston isn't shooting hoops, he's helping his grandfather with the plants in the backyard.

“Pepper plants, bell peppers, jalapenos, onions, tomatoes, and a large cabbage,” said Glenn Scarboro.

Two months ago, Jackston Scarboro brought home a small cabbage.

“My third grade teacher, Mrs. Macie Tanner, gave it to us to bring home and grow. We put it in this pot and we fertilized it and watered it,” said Jackston.

It's a part of the Bonnie Cabbage Program that started in 1996.

Over the years, the project grew to 48 states, specifically targeting third graders.

Jackston’s mother, Wendi, says that he hasn't stopped taking care of the plant since he received it.

“I'm very excited for him, and he's very excited,” said Wendi. “I'm super proud.”

He never thought it would get this big, but with the help of his family and his grandfather's green thumb, it’s the biggest in his class.

His grandfather says that this teaches him important qualities.

“You got to have responsibility. When I was that age, I had it, and got to do things,” said Scarboro.

They used pond and fish water and his mother says that he hopes he wins the competition.

“We're going to take it to Roach Farm and Garden and do an official weighing of it, and then we can send it to Bonnie Plants with their official weigh-in and he could get him a $1,000 to $3,000 scholarship,” said Wendi.
