The survey shows one in three will buy outdoor Christmas lights, and almost one in five will buy a wreath for their front door.
At least one in three of those surveyed feel "a warm sense of community spirit" when they see a house with outdoor Christmas decorations and also feel "a heightened sense of personal joy and happiness".
Men are 40 per cent more likely to speed between £40 - £80 on outside decoration such as lightings and wreaths – that is 50 per cent more than what women are likely to spend.
Wyevale is also selling 60 per cent more Christmas cactus than in 2014.
Category manager Mairi Devlin said: "The Christmas Cactus is certainly making its presence felt and adds to the gift options open to customer. There is no doubt that the cactus with its longevity, robust personality and easy to look after requirements make it a very appealing purchase both as a gift and for your own home. The idea of giving a gift which, if looked after correctly, will still be blooming in years to come is very compelling.
Christmas Cactus are £7.99. They are also included in the Wyevale Garden Centres 2 for £10 mix & match with Poinsettias & Azalea.
Wyevale Garden Centres Christmas product buyer Laura Comfort said: "As the whole family gather to pick up both the variety of inside and outside Christmas decorations, men will dominate the outdoor section, taking control of the purchases and typically spending more money than women. Whilst we do generally see men buying for example an extra Christmas tree for outside or masterminding the outdoor lighting, we are now seeing how they are spending more than women on such items."
Christmas Wreaths at Wyevale Garden Centre are 50-60 per cent sold through. They have a replica of the wreath featured at No.10 Downing Street last year and made by the same supplier. Red and orange ranges and scented wreaths are top sellers this year.
