In Conversation with Jack Merlo

What is your primary guiding principle when curating plantings for a garden?
Everything starts with context. I look at the location, the architecture and the surrounding streetscape, then tailor the planting so it feels as though it belongs. Along the coast that might mean a focus on Australian indigenous species, while other areas often suit a mix of indigenous and exotic. I also like to echo elements of the owner’s previous garden, especially for downsizers, so there is a sense of familiarity. Structural evergreen planting on the boundaries creates privacy and a calm green backdrop.

What should homeowners plant heading into summer to add long-term value and buyer appeal? Provided the garden is well-maintained, most plants can go in year-round, although I avoid starting a new garden in the height of summer when plants can struggle to establish. The most important thing is understanding aspect and conditions. You need to select plants that will thrive in your level of sun, shade, wind or coastal exposure. I like to begin with structural greens and specimen trees, then layer in seasonal colour that can be rotated over time, using flowering trees and classic shrubs to bring freshness and interest.

If you could add only three things to instantly beautify most Melbourne gardens, what would they be, and why?
I would start by making sure the outdoor space is functional and connected to the house, so living areas flow easily to entertaining zones and the garden feels like an extension of daily life. Next, I would refine the material palette so the relationship between architecture, interiors and landscape is cohesive. Finally, I would invest in both good planting and good lighting. A well-planned planting scheme that offers privacy and year-round appeal, combined with subtle, layered lighting in trees, along pathways and around seating, transforms the garden into a space you want to use day and night.

What is your favourite low-maintenance planting palette for terraces and courtyard gardens? On elevated terraces, I often begin with evergreen structure, such as bay trees clipped into a simple form, to create a strong backdrop. In front of that, hardy shrubs like compact Indian hawthorn deliver neat foliage and seasonal flowers without demanding too much attention. I then soften the edges with cascading plants such as silver nickel vine and introduce climbers like star jasmine for fragrance and additional greenery. Textural plants such as foxtail fern bring an architectural quality while remaining tough.

In your own garden, which plants will you always include, no matter the brief?
There are a few species I return to because they provide beauty, structure and seasonal interest. Flowering dogwoods are a favourite for their delicate summer blooms and rich autumn colour. Hydrangeas and bay trees add softness and a classic evergreen backdrop, while Japanese maples and ornamental cardamom round out the palette, offering fine texture and a sense of quiet refinement.
