Living within earshot of the waves is a privilege, but the sea makes demands of a garden. Salt-laden wind scorches leaves, snaps tender stems and dries soil faster than any inland plot. The good news is that a coastal garden can be every bit as productive and beautiful as one in a sheltered valley — you simply have to plan for wind rather than against it. Here is how to build a garden that bends instead of breaking.
Spend a full season watching your patch before you spend a penny on plants. Wind rarely arrives evenly; it funnels down side passages, gusts around gable ends and races across open ground in a way that no map will show you. In most of the UK the prevailing south-westerlies do the damage, but on the east coast a February north-easterly can be far more brutal.
Nothing else you do will matter as much as getting shelter right. A solid wall or fence seems the obvious answer, but it creates howling eddies on its leeward side that can be worse than open wind. What you want is a permeable barrier — something with roughly half its surface open to the air — which filters and slows the wind rather than blocking it. Reducing wind speed by even half transforms what you can grow.
A shelterbelt protects a distance of roughly four to six times its height downwind, so height matters as much as density. Establish a salt-tolerant evergreen hedge on the seaward boundary, and use woven hurdles or slatted fencing as a temporary screen while it grows. Plant in autumn, water through the first two summers, and resist the temptation to trim the top until the hedge has reached the height you want — trimming early simply encourages dense, wind-tight growth.
Coastal ground is often thin, stony and free-draining, with salt accumulating in the top few centimetres and precious little organic matter to hold water. Improve it patiently and you will see the difference within a season.
Look for glaucous, leathery, hairy or narrow leaves — these are nature's windproofing. Silver and grey foliage reflects light and shrugs off salt, while plants with a naturally compact habit suffer less stem damage.
Plant small specimens in autumn and group them closely so they shelter one another while they establish.
Kitchen gardening on the coast is perfectly possible, and some crops positively relish the conditions. Chard, kale, purple sprouting broccoli, broad beans, beetroot, carrots, onions, garlic and early potatoes all cope well. Leaf crops suffer most from salt burn, so give young plants a low fleece tunnel or cloche for their first month.
Herbs are the coastal gardener's secret weapon: rosemary, thyme, sage, sorrel and lovage thrive in free-draining, sunny ground. Autumn-fruiting raspberries and blackcurrants are reliably tough, and strawberries will crop generously in a warm, sheltered pocket. If you have a south-facing house wall, use it — trained apple, pear or plum cordons against that wall enjoy a microclimate worth several degrees. Choose early-ripening varieties and avoid anything that flowers late, when wind and salt are at their worst.
Trim hedges in late spring, once the risk of salt burn has passed, so they are dense before the next winter. Plant and mulch in autumn while the soil is still warm. In winter, check tree ties and repair any storm damage promptly — a loose plant rocks and tears its own roots. Through spring and summer, water deeply, feed sparingly, and watch the windward edges of leaves for browning, which tells you a screen is needed.
Coastal gardening asks for a little more thought and a little more patience. In return you get luminous light, mild winters and a garden that feels genuinely part of the landscape.
