The new growth is made up of tiny shoots which have between one and six small leaves measuring between two and four centimetres each.
Andrew Poad, general manager for the National Trust at Hadrian’s Wall, is urging the public to keep away from the stump and not touch the shoots.
“Our aim is to leave all eight shoots to grow for a few years to see how they develop,” he said.
The next few weeks and months are “vitally important for the success of these shoots forming into the reinvigorated tree”, he said.
Meanwhile, seedlings gathered in the aftermath of the tree’s felling continue to flourish at the National Trust’s Plant Conservation Centre, with saplings possibly being planted in the next two years.
Two men are due to appear in court on 27 August having denied causing criminal damage to the original tree and to Hadrian’s Wall.
