He toned down his Spooky Zoo idea this year after the event brought in 1,200-1,500 children in October half term 2013, which Barnden said was "getting scary". He added: "You only have a week for Halloween and you don't want to turn it into a monster. You need to look after your regulars."
With gardening sales generally over, Christmas sales yet to begin and half term on, Halloween is a good opportunity to promote Christmas events, sell grotto tickets and fill the coffee shop. But Barnden said Halloween product sales are not high.
Woodcote Green shows are bookable online at £2.50 a child and it runs a "find the golden pumpkin" competition in store.
Spooky Zoo is on at Chessington Garden Centre from 25 October to 2 November. The event gives children a chance to see, handle and have their photo taken with lizards, snakes, spiders and crocodiles. The cost is £2 per child for a 45-minute session and games with the Rainbow Trust Children's Charity.
Other Halloween events include Spooky Films, face painting, a slime tombola, Thriller flash mob, skull skittles and fancy dress.
