The latest (29 August) viewing figures show the programme with 1.7 million viewers, down from 3.4 million for the primetime Wednesday 8pm BBC1 garden makeover show, which launched its four-part run on 15 August.
The show, presented by Joe Swift, Anneka Rice and Phil Tufnell has drawn criticism from TV reviewers and online forums as well as Twitter.
Poster Keiran O'Regan wrote: "The Flowerpot Gang on BBC1. Are the BBC having a laugh."
Gardeners Corner poster EvilLen called the programme "weak and predictable", and Armandii wrote: "It's AKA Love Your Garden, which is AKA Groundforce. Let's have some quality gardening."
A BBC representative said: "The Flowerpot Gang was an original format which went beyond just gardening to bring together local communities and encourage them to get involved in transforming their local environments.
"We are glad that we were able to try something new and - with 3.4 million viewers - we are pleased at how many people have tuned in to watch Anneka, Joe and Phil."
