Clairsy & Lisa are always low-key coy when chatting to the greenest of thumbs, Costa Georgiadis.

“I know those thumbs are a light shade of green,” he graciously assured The Bunch on Wednesday.

“We’ve just got to work on the depth and tone of that colour.”

He also knew the very plant to do it.

“I say to people start there and watch the addiction slowly set in.”
