The Client Challenge

The client had a well-furnished contemporary balcony with an outdoor sofa, a cushion palette, and beautiful city views. The planter box was the problem: it had failed with live planting more than once, and the combination of direct sun exposure, wind at height, and the realities of balcony watering schedules made any solution a repeat of the same outcome.

• The planter had irrigation infrastructure already installed
• The depth and soil profile of the planter were unsuitable for most species
• The planter was too narrow for a container to sit inside it 
• The client needed something that could go directly into the existing mulch

The Design Objective

The brief was to maintain the city view and add structure to the balcony without erecting walls or fences. The client asked for us to:

• Use the existing mulch as the installation medium 
• Create visual rhythm across the full planter length 
• Match the formality of the rest of the balcony

The Solution and Key Benefits

We specified the Boxwood Topiary Shrub with Ground Spike because it seemed like the perfect defining feature for this application. Each topiary pushes into the garden bed without a separate pot, weighted base, or anchoring system. On a balcony planter filled with existing bark mulch, this means installation looks like this: push, position, done.

We spaced the topiaries evenly across the planter length and filled the gaps between each base with white river pebbles to conceal the mulch. 

Key benefits:

• Ground spike installs directly into mulch or soil 
• UV-resistant with UVTex inhibitors integrated within the leaf to avoid fading
• SafeTex certified, non-toxic, RoHS compliant 
• Low-maintenance, with no watering, pruning, or fertilizing

Installation Approach 

Installation for this project required no tools, no fixings, and no structural intervention.

• We measured the full planter length and divided it by the number of topiaries to establish even spacing. 
• We then pushed the spikes into the mulch to full depth so that the spike is fully embedded, so the topiary base sits at or just above the mulch surface 
• Then, we filled between bases with river pebbles or similar to conceal the mulch, define the planting bed visually, and give the planter a surface finish that matches the quality of the topiaries 
• In the end, we stepped back to assess the rhythm from the main viewing position before treating the installation as complete.

The Result

The balcony planter that had failed with live planting twice became the strongest design element on the balcony. The formal cone topiaries create a structured green border that frames the heritage tower and city tree canopy visible behind without blocking any of it. The outdoor furniture in the foreground now has a setting that belongs with it.

The client adds nothing to their routine after this installation. The planter works, permanently, exactly as it looks in the photos.
