The tree is believed to be the largest Christmas tree in the country and rigging the lights on it takes up to nine hours.
Decorating the tree will be carried out by arborists from Wakehurst’s Conservation and Woodland team shortly after first light. While one of the team scales the tree, colleagues will pass the lights over from two high level work platforms.The tree will form the centrepiece of Christmas festivities at Wakehurst and will be switched on at a ceremony on November 26.
Wakehurst conservation and woodland manager Iain Parkinson said: "It’s a bit like decorating the tree at home – but on a giant scale! We have to lay out the lights on the grass beforehand to check from any broken bulbs and unravel any tangles.
"Getting 1,800 lights in place is a long job, but it is always worth it when we see the tree lit up and decorating the tree marks the start of the build up to Christmas here at Wakehurst."
