Increasingly hot summers, watering restrictions, draining soils... What if drought wasn't an obstacle but an invitation to create the most beautiful and freest bed in your garden? Welcome to the world of the dry garden.
Understanding the dry garden principle
The dry garden — or xeriscaping — is not an arid and desolate garden. It's a planting system designed from the start to function without additional watering once plants are established, relying solely on natural rainfall.
The central idea: rather than forcing water-hungry plants to survive in dry soil, we choose species that love drought, that have developed fascinating evolutionary strategies — silvery leaves reflecting heat, succulent stems storing water, taproots plunging to great depths.
"Drought is not a problem to solve. It's a constraint to embrace — and it leads to gardens of singular beauty."
Preparing the soil: gravel, ally number one
Soil preparation is the key step. Dry garden plants hate wet feet: draining soil is non-negotiable. If your soil is clayey and compact, you'll need to amend it before planting.
- Decompact to 30-40 cm depth with a broadfork or digging fork.
- Incorporate 30% gravel or pozzite to improve drainage.
- Plant the vegetation respecting spacing — they will spread.
- Cover the entire surface with a mineral mulch (decorative gravel, slate, pebbles) 5-8 cm deep.
🪨 Mineral vs organic mulch: For the dry garden, prefer mineral mulch (gravel, pebbles): it doesn't retain excess moisture, warms the soil at night and creates the microclimate these plants love. Plus, it's decorative and lasts for years.
Star plants of the dry bed
The catalogue is vast and often spectacular. Here's a tested and approved selection for our regions, between Mediterranean plants and natives from dry areas.
| Plant | Type | Asset |
|---|---|---|
| Lavender | Perennial | Long flowering, bee-friendly, fragrant |
| Stipa pennata | Grass | Spectacular feather effect in wind |
| Agapanthus | Bulb | Blue-white flowers July to Sept. |
| Sedum spectabile | Succulent | Pink autumn flowering, pollinators |
| Echinacea | Perennial | Pink flowers, seeds for birds |
| Achillea 'Moonshine' | Perennial | Silvery foliage, pale yellow flowers |
| Rosemary | Shrub | Evergreen, aromatic, early flowering |
| Field scabious | Native | Mauve flowers, butterflies and bumblebees |
Three golden rules for success
Beyond plant choice, a few simple principles make all the difference between a bed that thrives and one that languishes.
- Plant in autumn, not spring. Autumn rains allow roots to establish before the first heat. A well-rooted plant resists its first summer drought much better.
- Water for the first two years to support rooting, then gradually wean. Patience is key: the dry garden becomes autonomous over time.
- Don't cut everything back in autumn. Dry stems protect crowns from frost and offer precious shelter for overwintering wildlife. Prune in spring, just before growth starts.
🌡️ Exposure, the decisive factor: A dry bed in full south or south-west is ideal. In north exposure or in a shaded area, conditions are too different and most of these plants would languish.
A free, beautiful and sober garden
The dry garden is perhaps the most liberating type of garden there is: once established, it grows, flowers and self-seeds in great autonomy, while you enjoy summer without guilt about water restrictions.
Start with just one bed, even small. Choose five to seven complementary species in terms of height and flowering period, prepare the soil well, mulch generously — and watch the magic happen from the second season. 🌾
