Episode 4

Carol Klein and Diarmuid Gavin lead the search along with guest judge and keen gardener Katie Piper to find Northern Ireland’s greatest garden.
Up first is Colin’s surprising suburban rustic garden in suburban Ballymena.

In the foothills of the Sperrin Mountains, near the windswept Glenshane Pass, Adrienne has transformed two acres using a variety of planting styles.

The final stop is in Dromore, where Julietta has created a garden designed with her young family very much in mind, including a wild meadow playground and a courtyard filled with edible plants.

There are mixed opinions at the judging table – so which will expert judges Diarmuid, Carol and Katie feel deserves a place in the Greatest Garden final?
