Heatwave in the garden: choosing the right planters and plants
Every summer, the same days return: a cloudless sky, sun beating down on the terrace from midday, and potted plants that, without attention, wilt before evening. Yet a terrace or balcony can withstand a heatwave without losing its charm. It all comes down to the choice of planters, their placement, and a few simple steps that make the difference between a space that suffers and one that breathes.
The container, the first defence against heat
Even before watering, it all starts with the planter itself. Some materials store heat and release it back to the roots all night long. Others, thicker and more mineral, instead act as a buffer and keep the root ball cooler for longer.
Glazed ceramic: protective thickness
Glazed ceramic remains one of the most temperate materials in full sun. Its thick wall limits temperature fluctuations around the roots, while offering a wide palette of colours and finishes to create a Mediterranean atmosphere. The Lancelot model, available in several colours such as Honey, jade or Tropical lagoon, is a fine example of this ability to combine aesthetics and plant comfort.
Recycled fibre concrete: the freshness of mineral materials
Fibre concrete shares this mineral quality: a dense wall that moderates sun exposure, paired with clean, contemporary lines. The Kubix model, with its bold cubic forms, embodies this quiet strength: a piece that structures a terrace while offering your plants a more stable environment in intense heat.
Conversely, dark colours and thin materials exposed to full sun heat up more: reserve them for shaded locations or the coolest hours of the day.
Placement: shade, your best ally
A well-chosen planter is not enough if its position leaves it continuously exposed during the hottest hours. A few simple principles are enough to turn a scorching terrace into a cool corner:
- Choose an aspect that provides shade in the afternoon, the most intense period.
- Place planters close together to create a cooler, more humid microclimate.
- Use tall plants, such as an olive tree or dwarf palm, to shade lower planters.
This is the whole principle of plants as climate allies: they do more than decorate a space, they work. They breathe, cool, protect and soothe. A generously planted terrace remains noticeably more pleasant to live in than an entirely mineral space, even during the hottest hours.
The right steps for a peaceful summer
Water at the right time
Water early in the morning or at the end of the day, never in full sun: the water evaporates before it even reaches the roots and can scorch the foliage if it remains in droplets on the leaves. Deep, less frequent watering encourages roots to grow deeper, rather than multiplying small surface applications.
Mulch to limit evaporation
Mineral mulch (clay pebbles, light-coloured gravel) or organic mulch on the surface of the planter limits evaporation and maintains more consistent coolness around the roots. It is a simple, discreet step that noticeably extends the comfort of your plants between watering.
Choose plants that thrive in summer
Some plants make their way through the warm season with natural ease: olive trees, lavender, agapanthus, ornamental grasses and cacti particularly appreciate the sun and require little maintenance. Paired with a well-chosen mineral planter, they create a summer scene that is both generous and serene.
Creating a cool, vibrant terrace all summer long
A beautiful summer terrace is not simply an assortment of planters: it is a considered composition, where material, placement and plants complement one another to create a space where it is pleasant to stay, even in the height of a heatwave. By choosing containers that moderate heat and organising shade and watering wisely, every outdoor space can become that cool corner you dream of returning to each evening.
