One of the most difficult parts of growing giant pumpkins is thinning the plants to allow for just one or two giant pumpkins to grow, as one local gardener will attest.

On Monday, Science North staff scientist Stephen Smith thinned the Morning North and Science North pumpkin plants. Now, both CBC Sudbury and Science North will root for one plant, hoping it will produce the largest pumpkin.

"That really hurts," said Smith as he yanked one of the smaller pumpkin plants from the ground. "You can hear it pulling and ripping a lot of root growth."
