It borrowed its format from Top Gear of the Pops, a similar one-off special which aired as part of Comic Relief 2007.

Regular Top Gear hosts Jeremy Clarkson, James May and Richard Hammond take over sportsman Steve Redgrave's garden, to dispense advice on creating a zero maintenance lawn, installing an impressive water feature and getting rid of unwanted plants.

The Top Gear team impersonate and belittle the show Ground Force, and provide a garden makeover for British Olympian Sir Steve Redgrave.

Meanwhile, Clarkson and May arrive back from a garden center with their desired equipment, only to destroy the push bike of one of Redgrave's children.

His explanation of his decision for using a homemade bomb to finish the job quickly and easily is made more difficult with the arrival of the Salvation Army Brass Band drowning his voice out.

The special ends when Clarkson activates his turbo-powered water feature which sends the top of the fountain flying through the air and crashing into the greenhouse he built, destroying every window upon impact.
