Chelsea flower show: a garden with a green message for the green-fingered

RHS entry includes old concrete and drainpipes alongside the blooms to highlight the importance of environmentally friendly gardening

A week before the opening of the UK's most prestigious flower show, the site is full of JCBs and people in hi-vis vests with steel-capped boots. Some gardens still look like construction sites, including part of the RHS Cop26 Garden - except that this one is finished.

Drainpipes, a manhole chamber, old concrete and industrial offcuts lie strewn around. When I told people we were taking this stuff to Chelsea they thought we were fly-tipping," says Marie-Louise Agius from landscaping company Balston Agius, who designed the garden. It has taken 12 people three weeks to put together.
