Plant combinations for sandy soil: thriving on dry, light ground

Sandy soil: lighter than you think

Where clay-soil gardeners wrestle with heavy, wet material, sandy-soil gardeners face a different challenge. The ground is light, dries out fast and warms up early in spring — ideal for early plant growth. But there is a flip side: water and nutrients drain through at lightning speed. The trick is to choose plants that actually thrive on that.

Think Mediterranean. Think prairie. Think silvery foliage and deep roots. The most beautiful sandy-soil gardens look as if they have been lifted straight from Provence or a coastal heath — and that is precisely the charm.

Combination 1: Mediterranean dream

Lavandula angustifolia 'Hidcote' (lavender) forms the foundation. These compact, deep-purple bloomers are at their absolute best in dry, lean soil. Plant them as a low hedge or in groups of five. Behind them, set Perovskia atriplicifolia (Russian sage) with its silvery-grey foliage and lilac plumes. At the front, Stachys byzantina (lamb's ear) finishes the picture with woolly, silver-grey leaves that creep across the sandy ground like a carpet.

Together they create a dreamy scene in purple, silver and lilac that holds from June to September. Bonus: butterflies and bees adore it.

Combination 2: Grass-driven dynamics

For a more contemporary look, combine Stipa gigantea (giant feather grass) with Achillea 'Terracotta' (yarrow) and Eryngium × zabelii 'Big Blue' (sea holly). The feather grass sways at two metres tall, the yarrow brings warm orange-terracotta tones and the steel-blue sea hollies add a tough accent.

Plant the feather grass as a specimen or in a trio. The yarrow and sea hollies go in larger drifts — seven to nine plants — for the best effect.

Combination 3: Heathland atmosphere

On poor sandy soil, a heathland-style planting works phenomenally. Calluna vulgaris (heather) in mixed colours, combined with Molinia caerulea (purple moor grass) and Erica carnea (winter heath). The molinia turns golden yellow in autumn, the heathers bloom in waves from summer to winter and the whole scene feels as though a wild heath has wandered into your garden.

Combination 4: Edible sand garden

Sandy soil is perfect for herbs. Plant Thymus vulgaris (thyme), Rosmarinus officinalis (rosemary) and Salvia officinalis (sage) together in a sunny bed. Add Sedum spurium (stonecrop) as ground cover. You get a herb garden that looks fantastic, smells wonderful and barely needs watering.

Combination 5: Bulb paradise

Sandy soil is paradise for bulbs. Tulipa sylvestris (wild tulip), Crocus tommasinianus and Allium sphaerocephalon (drumstick allium) naturalise effortlessly in well-drained sand. Plant them among ornamental grasses for a natural effect that improves every year.

Tips for success on sandy soil

Add compost annually — not to make the soil heavier, but to improve its ability to hold water and nutrients. A three-centimetre layer, lightly worked in, makes a big difference.

Mulching is your best friend. Gravel, shells or bark chips slow evaporation and give the garden a polished look. On sandy soil, a mineral mulch (gravel, grit) often works better than organic, because it breaks down more slowly.

Water in the early morning, deeply but less often. This trains roots to reach down deep.
