Transform a discarded trolley into a vertical herb garden for your smallest spaces

In short: Limited space does not mean you cannot grow your own fresh herbs. By repurposing a portable trolley with perforated shelves, you can create a tiered vertical garden that moves with the sun. This clever design uses gravity to water your plants while maximizing every inch of your kitchen or balcony.

The secret to a successful herb tower lies in utilizing the verticality of a portable trolley, which can often be salvaged from op shops or hard rubbish. To ensure the structure remains functional, you must select a unit with netted baskets or shelves featuring perforated holes. These openings are essential for drainage, but they require careful lining to prevent soil loss. By using a combination of hessian fabric and pond liner, you can create a durable, contained environment for your plants. The hessian holds the soil, while the pond liner—when punctured—manages water flow and extends the life of the trolley.

The tower design naturally creates a gradient of growing conditions, which you can exploit by placing specific herbs on different levels. As water trickles down from the top, the lower shelves remain consistently moist and shaded, making them ideal for plants like Vietnamese mint (Persicaria odorata) or common mint (Mentha spicata cv.). Because mint is a vigorous grower, trimming one-third of the root ball before planting helps manage its spread. Middle shelves, which receive moderate sunlight, are well-suited for leafy greens like rocket (Eruca vesicaria cv.) and lettuce (Lactuca sativa cv.), or the edible flowers of nasturtium (Tropaeolum majus cv.).

The top shelf, which receives the most direct sun and experiences the fastest drainage, is the perfect home for sun-loving herbs like oregano (Origanum vulgare) and chives (Allium schoenoprasum). When planting, it is best to avoid species with large root systems, such as carrots, parsnips, or sorrel, as they require more depth than a trolley tray typically provides. By working from the bottom up and selecting shallow-rooted varieties, you can maintain a productive, portable garden. This system not only saves space but also offers the flexibility to wheel your harvest into the light as the sun moves throughout the day, ensuring your fresh ingredients are always close at hand.
