Colin and Donna Craig-Brown were working in their New Zealand garden in late August.They were removing unwanted plants when they found something strange.After a little digging，Colin discovered there was a very large potato growing in his garden.And they never planted potatoes!
   "We couldn't believe it， " Donna said. "It was just huge." The couple worked the potato out of the soil and brought it to a scale.It weighed almost 8 kilograms.
   The potato may be the largest ever recorded.In 2011，a large potato from Great Britain weighed just under 5 kilograms.The New Zealand potato，now named Doug，could break the record.The Craig-Browns asked Guinness （吉尼斯） to recognize their potato as the largest ever.They are waiting to hear from the organization.
   The potato has become famous in the town of Hamilton，Colin took Doug on walks round the neighborhood， "We put a hat on him.We put him on Facebook，taking him for a walk，giving him some sunshine，" Colin said. "It's all a bit of fun."
   Colin said he does not have any special gardening methods to pass on.Normally，he and his wife fertilize （施肥） their garden with waste from cows and dried grasses.The Craig-Browns were growing cucumbers （黃瓜） in that part of the garden，so they didn't expect there was a potato.It may have been growing for two years or more.
   The potato is getting a little old now，two months after it was taken from the ground.
   Right now，it is in the freezer.
