Christmas tree tips

Sam and Josh Lyle set up their business Pines and Needles when they were only 15 years old and successfully sell 60,000 trees a year to customers including Sir Elton John and Madonna, and have revealed the large firs are like humans because they don't like sudden change and has a tendency to drink quite heavily over the festive period.

Speaking about the best ways to keep a tree alive, they said: ''Do not expose your tree to sudden changes in temperature. Trees like most people are creatures of habit and prefer steady conditions.

''Your Christmas tree may drink two to three pints of water per day, depending on its size and your central heating settings.

''This is very important as once the water level drops below the tree's trunk, sap will re-seal the bark within a few hours, preventing the tree from drinking any further water even if you then re-fill the Christmas tree stand.''
